An Empirical Analysis

Do changes in the dollar's value on foreign exchange markets affect prices in the United States?
This article, based on an Atlanta Fed working paper
"The Dynamic Relationship Between the Dollar and
U.S. Prices: An Intensive Empirical Investigation,"
suggests a significant connection between moves in
the dollar and periods of inflation and disinflation.
4 OCTOBER 1986, E C O N O M I C R E V I E W

W h e n floating exchange rates were adopted in
the early seventies, they brought wide fluctuations in the values of world currencies on foreign exchange markets. Economists have been
trying ever since to determine how, and if, changes
in the value of the dollar on foreign markets affect
domestic prices. The interaction is complex. Like
many macroeconomic relationships, the effect of
the dollar's value on domestic price levels involves complicated lag patterns overtime as well
as possible feedback from prices to exchange
rates.

Significant correlation between moves in the
dollar's value and fluctuations in U.S. prices could
have important policy implications, since it suggests that price stability will be hard to attain as
long as exchange rates continue to fluctuate
widely. Periods of unexpected dollar depreciation would be associated with worsening inflation, while unexpected appreciation would be
associated with disinflation. Using a methodological approach especially suited to the complexities ushered in by floating exchange rates, our
research confirms a group of previous studies
that used other methods to discover a significant
dollar-price level relationship and suggests that
changes in the dollar's value may be associated
with larger price changes than previous studies
have indicated. Our results provide a stylized description of past relationships and are not suitable
for direct or precise extrapolation into the future.
Most existing research, which uses different
methodologies than ours, estimates that a permanent 10 percent drop in the dollar's value is associated with an eventual increase of 1 to 2
percent in the consumer price index. Two recent
studies find essentially no impact. Our study
finds a definite price response, with the increase
being approximately 4 and 3/4 percent. All of
these estimates are based on the limited data
available on the past relationships between the
dollar and prices. U p until a few years ago most
Americans had little direct experience with exchange rate changes, though other countries have
certainly experienced them. However, since the
advent of floating exchange rates, the dollar's
value has moved up or down several times by

Periods of marked decline in the dollar's value such
as 1971-73 and 1977-78 appear to be followed

more than 10 percent within a 12-month period.
For a variety of reasons, estimated relationships
involvingthe dollar and prices based on past data
may not necessarily remain unchanged in the
future. Moreover, the dollar is not the only variable which affects inflation. Nevertheless, our
finding of a strong past association between the
dollar and subsequent inflation suggests that the
dollar bears close watching to help gauge the
outlook for inflation.
Perhaps the most well-known measure of the
overall price level is the consumer price index
(CPI), which measures the cost of living for an
average household in the United States. It is not
obvious that there should be an important link
between the value of the dollarand the CPI. After
all, U.S. merchandise imports, which are presumably the items directly affected by exchange
rate changes, constituted less than 10 percent of
the U.S. gross national product in recent years.
Nevertheless, a casual look at the behavior of
inflation (in terms of the consumer price index)
compared with an index of the dollar's exchange
value from 1970 to mid-1985 (as measured by the
Federal Reserve Board's trade-weighted index)
shows a relationship (Chart 1). During this period
phases of dollar depreciation such as 1971 -73 and
1977-78, indicated by declines in the dollar index,
tended to be followed by increases in inflation,
5

whereas the dollar's appreciation in 1981-84 is
matched by subsequent disinflation.
To understand this relationship fully, a dynamic
mathematical model that can account for patterns of change in a given time period is essential.
During the era of fixed (or pegged) exchange rates
when the values of currencies held steady except
for occasional large jumps, modeling the impact
of shifts in the dollar's value was fairly straightforward. W i t h floating exchange rates, however, the
values of currencies are always moving. W e cannot say simply, for example, that a drop in the
value of the dollar at one particular point generated the increase in prices at another particular
point; rather, a whole pattern of changes in the
dollar's exchange rate must be compared with a
whole pattern of changes in prices. Another complicating factor is that the impact on prices of
changes in the dollar's value is felt only incrementally over time. For example, the effects of a particular shift may be noticeable in three months,
more acute in four months, peaking at six months,
diminishing at eight months, and disappearing in
twelve months. The aftermath of a change in the
dollar's value moves through the rest of the
economy like a wave rather than affecting it in a
more easily discernible one cause, one effect pattern. To determine when and to what extent the
effects of alterations in the dollar's value have
emerged, when they have crested and when they
have ebbed, w e have used a group of statistical
techniques, time series analysis, to develop
mathematical models of the lag structure. They
describe, as it were, the size and shape of the
wave.
Other studies of the interplay between the
dollar's value and domestic prices attempt to
model the specific channels, such as import
prices or wages, through which the dollar might
affect domestic prices. In addition, these studies
attempt to gauge the impact of the dollar in the
absence of change in other factors, such as real
gross national product and monetary policy. Our
time series analysis enables us to create a model
that will reflect the nature and extent of the price
response to the dollar's movement regardless of
how the dollar affects prices, whether through
import prices, wages, or some other channel. Our
approach differs from others in that it does not
provide a detailed breakdown of the dollar's
impact in terms of the specific channels through
which the impact travels. In addition, while a few
other studies attempt to provide an explanation
of why the dollar moved (in terms of changes in
6




foreign fiscal or monetary policy, for example),
our approach does not; w e focus solely on the
observed interaction of prices and the dollar's
value during the period of floating exchange
rates.
Our results indicate that during the period w e
analyze, exchange rate movements were followed
by substantial changes in the price level. If wide
fluctuations in exchange rates continue and the
linkage between the dollar and prices persists,
then achieving price stability, which is one of the
goals of monetary policy, may be difficult.
To reduce the volatility of the dollar, some
economists advocate a return to greater fixity of

exchange rates, perhaps through a system of
"target zones" as in the European Monetary System, which links the currencies of a number of
European countries. Other economists insist that
the current floating rate system would exhibit less
volatility if governments would follow more stable and predictable policies. W h i l e the debate
between those advocating a return to fixed rates
and those committed to floating rates is beyond
the scope of this paper, our results indicate that
there is an important link between the dollar and
the future price level which bears consideration.

Measuring the Impact of Exchange Rate
Changes
Interest in the effect of exchange rate changes
on U.S. prices has grown considerably since the
breakdown of the Bretton Woods system of pegged
exchange rates in the early 1970s. Near the end of
OCTOBER 1986, E C O N O M I C REVIEW

World War II, delegates from many nations met in
the resort of Bretton Woods, N e w Hampshire, to
plan an international monetary system that would
promote economic growth and international trade
in the post-war world. In the system which grew
out of this meeting, governments intervened in
the foreign exchange markets to maintain pegged
exchange rates, often foryears at atime. For example, the exchange rate between the dollarand the
British pound was maintained at $2.80 per pound
from 1949 to 1967. The breakdown of the Bretton
W o o d s system introduced a period of floating
exchange rates that has continued to the present
day.

"If wide fluctuations in exchange
rates continue and the linkage
between the dollar and prices
persists, then achieving price
stability, which is one of the goals of
monetary policy, may be difficult."

As shown in Chart 1, the years of floating exchange rates have been marked by large fluctuations in both the exchange value of the dollar
and the U.S. inflation rate. Not surprisingly, economists have been drawn to investigate the apparent
relationship between moves in the dollar's value
and U.S. prices. Prior to the collapse of Bretton
Woods, analyses of U.S. inflation tended to focus
solely on domestic determinants. Monetarist literature concentrated on the U.S. money supply as
the source of inflation, while Keynesian literature
saw the rate of inflation as a result of excess
demand, which is identified with the unemployment rate in the Phillips curve framework used in
most of these studies. ' This approach seemed to
work well in explainingthe modest inflation of the
1960s, but it has proved inadequate since then. A
common tactic in more recent studies has been to
add energy or food prices as additional factors to
explain inflation, based on the rationale thatthese
prices have been subject to large externally generated supply shocks caused by OPEC and weather
conditions. 2 Other investigators have tried to
FEDERAL RESERVE BANK OF ATLANTA




determine the role of exchange rates as an influence on U.S. prices.
The idea that a connection exists between
exchange rates and overall price levels can be
traced to the theory of purchasing power parity. It
states that the exchange rate between any two
national currencies adjusts to maintain equality
between the purchasing power of a currency at
home (in terms of real goods and services) and its
purchasing power abroad after conversion into
the foreign currency. As a result, depreciation in
the exchange rate should be associated with a
proportionate increase in the ratio of domestic to
foreign price levels. For example, suppose the
exchange value of the dollar fell (or depreciated)
by 5 percent, while foreign prices rose 2 percent.
According to purchasing power parity, the ratio of
U.S. to foreign prices should rise by the amount of
the depreciation (5 percent). To obtain this result,
the U.S. price level would have to rise by approximately 5 + 2 = 7 percent. 3 However, empirical
analysis suggests that purchasing power parity is
not by itself sufficient to explain price movements
in recent years.4
Another strategy to account for the last decade
of price fluctuations has been to modify the descendants of Keynesian models of the 1960s to
include exchange rates or import prices as additional explanatory variables. This approach has
been mathematically specified in a number of
ways, which are reviewed in the study by P.
Hooper and B. Lowrey (1979).
In the single-equation method, the domestic
price level is viewed as a function of labor costs
(wages), demand pressure (unemployment), and
import prices. The effect of exchange rate changes
on the domestic price level is then inferred indirectly from statistical calculations that measure
the impact of import prices, c o m b i n e d with
analysis that considers the consequences of exchange rate changes for import prices. These
studies, adjusted for comparability by Hooper
and Lowrey, indicate that the long-run effect of a
10 percent depreciation of the dollar, with no
change in labor costs or demand pressure, is a rise
of 0.8 to 1.5 percent in consumer prices.5

This approach treats labor costs, demand pressure, and import prices as separate sources of
inflationary pressure, so that exchange rates affect
domestic price levels only through their direct
effect on import prices. However, it is plausible
that exchange rate changes might affect, perhaps
after a lag, both labor costs and demand pressure.
If this were the case, it would mean that the total
7

impact of exchange rate changes on the domestic
price level might be greater than their direct effect
alone would indicate.
In attempting to account for some of these
additional channels by which exchange rates
could affect domestic prices, other studies have
developed more complicated structural simultaneous equation models that incorporate exchange rate effects on labor costs and demand
pressure. Studies using this approach, as adjusted
for comparability by Hooper and Lowrey, estimate
that a 10 percent dollar depreciation will eventually result in a 0.8 to 2.7 percent rise in consumer
prices, with nearly all results below 2 percent. 6
More recently, R. Dornbusch and S. Fischer (1984)
and J. D. Sachs (1985) obtain somewhat larger
estimates, using different measures of exchange
rates and prices.
In contrast, two recent studies suggest that
exchange rates have little or no effect on U.S.
prices. W . T. W o o (1984) analyzes the G N P consumption deflator, a broadly based measure of
consumer prices, excluding food and energy,
with quarterly data from the second quarter in
1975 to the first quarter in 1984. Employing the
single-equation approach, he finds that neither
import prices nor the exchange rate have a significant impact on the consumption deflator excluding food and energy, once wages and oil prices are
incorporated. J. E. Glassman (1985) argues that
earlier studies overstate the effect of exchange
rates on domestic inflation because of the strong
correlation between exchange rate movements
and energy price shocks. In his view, relative
energy prices (and perhaps food prices) should be
treated as separate explanatory variables for
overall inflation. The results of his analysis, using
quarterly data that cover both fixed and flexible
exchange rate regimes, suggest that exchange
rates have no significant effect on U.S. inflation.

An Alternative Approach
In ouropinion, the behaviorof inflation and the
dollar's value under the flexible exchange rate
system have been substantially different than
under the Bretton W o o d s arrangement. Both inflation and especially the dollar have shown
dramatically greater volatility since the end of
Bretton Woods. W e have therefore based our
estimates solely on data from the period of floating exchange rates.7 Moreover, it is generally
8




agreed that the relationship between the dollar
and U.S. prices involves significant time lags, but
theory provides little guidance as to the length of
the lags or their pattern.8 Therefore, time series
analysis is a natural approach to analyzing the
data, because it is especially designed to uncover
the length and patterns of lagged effects. 9 A
model of the interaction between the dollar and
prices based on time series analysis accounts for
the impact of the dollar on prices regardless of the
channel, whether through import prices, labor
costs, demand pressure, or some other factor. O n
the basis of our preliminary results, w e allowed for

" B o t h inflation and especially the
dollar have shown dramatically

Bretton W o o d s . "

longerand less restrictive lag structures than those
imposed in most previous studies.
Time series analysis requires a sizable amount
of information on the relevant variables. Nowthat
the floating exchange rate regime has lasted more
than a decade, it is feasible to apply these statistical methods using monthly data that allow us to
extract the maximum amount of information
available. The sample period begins in April 1973,
afterthe floating exchange rate regime was fully in
place, and ends in June 1985. For reasons consistent with the methodology, none of the data are
seasonally adjusted.
In creating a mathematical model of the relationship between the dollar and prices, w e tested
to determine the validity of our assumption that
domestic prices respond to changes in the value
of the dollar. W e also had to determine if feedback existed so that changes in prices also influenced the value of the dollar. To accomplish this,
w e considered the price level in any particular
month as a function of its own past history plus a
shock or innovation that had nothing to do with
the price level's past history. In ascertaining
OCTOBER 1986, E C O N O M I C REVIEW

whether or not the shock or innovation in the
price level could be predicted at least in part
using past values of the dollar, w e found that
changes in the dollar's value did anticipate changes
in the price level. However, past values of the
price level did not appear to help in predicting
shifts in the exchange rate of the dollar.
To summarize movements in the value of the
dollar (e t ), w e use the Federal Reserve Board
trade-weighted dollar index.10 Several price measures are examined because economic theories
which distinguish between traded and non-traded
goods, or between export and import goods, sug-

prices. The natural logarithm of each variable is
used throughout to normalize the wide range in
values.11

Identifying the Dynamic Relationships
Between the Dollar's Value and Prices
To investigate the distributed lag relationship
between the dollar and U.S. prices, w e start with
the hypothesis that the price level in any month
(p t ) is a weighted sum of current and past values of
the exchange value of the dollar, plus a (possibly
complicated) random error term, n1t:12
(1) p t = a D e t + anet_i + a2et_2 + . . . + n 1 t

" A model of the interaction between
the dollar and prices based on time
series analysis accounts for the
impact of the dollar on prices
regardless of the channel, whether
through import prices, labor costs,
demand pressure, or some
other factor."

gest that exchange rates may not have a uniform
link to all domestic prices. Traded goods prices are
usually assumed to be highly responsive to exchange rates, while the prices of non-traded products, such as certain services and housing, are
not. In the case of exports and imports, it is sometimes argued that because the United States is
such a large factor in world markets, dollar prices
of U.S. exports are determined by U.S. costs of production and are affected little by exchange rates,
but that dollar prices of U.S. imports are somewhat more responsive to exchange rates. W e
investigate the dynamic relationships between
the value of the dollar and the following three
measures of U.S. domestic prices (p it ):
p 1 t = CPI, all items;
p 2t = CPI, services;
p 3 t = PPI, all finished goods.
The "CPI, all items" is an overall index, while the
"CPI, services" is one component of the overall
CPI containing mostly nontraded items, and the
"PPI, finished goods" is a proxy for traded goods

for all t within the sample period, where the a k 's
are coefficients (numbers that remain fixed
throughout the sample period). The coefficients
a k represent the dynamic response of prices to
current and past movements in the dollar. The
random error term, n qt , incorporates the variation in prices not attributable to exchange rate
changes.
A hypothetical example may help clarify the
meaning of equation (1). Suppose that a 4 = -0.1,
a 5 = -0.2, a 6 = -0.1, and all the other a k 's were zero.
In this case, the dynamic response of prices to
dollar movements has a fairly simple form. Suppose that the exchange rate fell (depreciated) 5
percent in December. There would be no associated price movement during December (because
ay = 0) or in the first three months afterward. I n the
fourth month (April), the price level would rise by
(-0.1) x (-5 percent) = 0.5 percent. In May, the
price level would rise by a further (-0.2) x (-5 percent) = 1.0 percent. In June, the price level would
rise by a further (-0.1) x (-5 percent) = 0.5 percent;
the price response would then be complete, and
the total change in the price level w o u l d be
approximately 2 percent.
Likewise, w e consider the hypothesis that the
exchange value of the dollar in any month (et) is a
weighted sum of current and past values of the
price level, plus its own random error term, n 2t :

a The variable e, represents the Federal Reserve trade-weighted dollar index. In all cases, 36 lags on the dependent variable
are included. The numbers in each column are the F-statistics and (in parentheses) the marginal significance levels for the
hypothesis being tested. For p, t and p2\<30 l a 9 s on the right-hand-side variable are always included, while for p 3 „ 18 lags on the
right-hand-side variable are included. The longer lags were included for the consumer price measures because, a priori, w e
would expect consumer prices to respond less rapidly to exchange rate (or other) shocks than producer prices; in addition, the
cross-correlation functions suggested longer lags for the consumer price measures.

To obtain preliminary information about these
relationships, L. D. Haugh (1976) suggests scrutiny
of the univariate residual cross-correlation function, which essentially shows when current movements in prices match past patterns of fluctuation
in the dollar's value, and vice versa.15
If the price level (pt) and the value of the dollar
(et) were not related to one another, then all the
coefficients a k and b k in equations (1) and (2)
would be zero. In that case, the residual crosscorrelations would be small in magnitude and randomly distributed about zero.
Figure 1 shows the univariate residual crosscorrelation function using the overall CPI as a
measure of prices. The first column gives the lag
length, in months. Negative lag lengths involve
the relationship of the dollar's exchange rate in
any given month to previous fluctuations in prices,
while positive lag lengths describe the price level
versus previous exchange rates. The column
labeled "Plots" represents the cross-correlation
function; large cross-correlations which could
indicate a relationship show up as several asterisks, while the smallest cross-correlations have no
asterisks. The vertical line in the center of the

"Plots" column represents the zero axis. W h e n
asterisks extend beyond the dots to the right and
left of the center line (a confidence interval of 95
percent), we can say that we are "95 percent sure"
that these correlations are different from zero.
The bottom half of Figure 1 (positive lags) gives
the cross-correlations between price residuals and
past exchange rate residuals; these cross-correlations are closely related to the a k 's in equation
(1). Observe that while the cross-correlations at
lags 2 and 3 are mildly positive, nearly all the crosscorrelation at lags 4 to 24 are negative, with an
especially large negative cross-correlation at a lag
of six months. The negative sign of these crosscorrelations suggests that depreciation of the
dollar (a decline in e t ) tends to be followed by an
opposite movement (an increase) in prices.
The top half of Figure 1 (negative lags) gives the
cross-correlations between exchange rate residuals
and past price residuals; these cross-correlations
are closely related to the b k 's in equation (2).
There is some indication of negative correlation
for the early months (lags -2 to -7), with a fairly random pattern otherwise.14 The cross-correlation

other price series are not presented here to save
space, but they show similar patterns.
Formal statistical tests can further help to determine how exchange rates and prices are related.
As mentioned earlier, if p t a n d e t w e r e not related
to one another, then the estimated residual crosscorrelations should be small in magnitude and
randomly distributed about zero. P. D. Koch and
S. S. Yang (1986) provide a test that checks for the
existence of a lead/lag relationship in the entire
set of cross-correlations. Their test is particularly
useful because it can discern patterns in the crosscorrelations. For example, suppose that none of
the cross-correlations, taken individually, are significantly different from zero, but a group of crosscorrelations for adjacent lags are all fairly strongly
negative. Unlike some other tests, the Koch-Yang
test is designed to detect such non-random patterns in the cross-correlations and to reject the
hypothesis that the variables are unrelated if the
non-random pattern is sufficiently strong.
W h e n applied to our data, the Koch-Yang test
indicates that the hypothesis which contends that
the price level and the dollar are unrelated can be
rejected for all three price series.15 The test results,
along with the residual cross-correlations, also
suggest that the lag distributions in question are
fairly long, extending over many months.
Having observed an apparent relationship bet w e e n the dollar's value and domestic prices,
further investigations were in order to determine
whether shocks to the value of the dollar lead
movements in prices, shocks to prices lead dollar
movements, or both. Using the test proposed by
C. W . J. Granger (1969), w e examined statistically
FEDERAL RESERVE BANK OF ATLANTA




whether movement in each variable, dollar and
prices, could be predicted more accurately using
its o w n past history plus values of the other variable, or simply on the basis of its o w n past history
alone (Table 1). In determining the direction of
Granger causality, w e test t w o hypotheses:
H n : e t does not Granger-cause p it ;
H 2 : Pit does not Granger-cause et.
The resulting F-statistics and marginal significance
levels are presented in Table 1. Larger values of F
(smaller marginal significance levels) pointtoward
rejection of the hypothesis being tested. Using
standard significance levels of either .10 or .05,
observe that H 2 (p t does not Granger-cause e t ) is
not rejected for any price series. However, at
those same significance levels, H-, (e t does not
Granger-cause p t ) is rejected for all of these price
series. Including past values of the dollar helped
significantly to predict prices, but including past
values of prices did not help to predict the dollar.
The results of this test suggested that shocks to
exchange rates lead price movements, but not
vice versa.16

The Lag Between Dollar Movements
and Price Fluctuations
As discussed in the Appendix, the results of the
Koch-Yang and Granger tests indicate that it is
appropriate to estimate the distributed lag going
from exchange rate movements to prices, as modeled in equation (1). Our estimates imply that a
permanent ten percent drop in the dollar w o u l d

approximately 1.6 percent after one year, 3.4 percent after two years, 4.3 percent after three years,
and ultimately 4.85 percent. A rise in the dollar
would have opposite effects (see Appendix).
The distributed lags shown in Table 2 between
the dollar's value (e t ) and other price indexes (p it )
also indicate substantial responses following exchange rate changes. The results for services are
particularly noteworthy. Since most of the services in the CPI are not traded internationally, it
seems plausible that exchange rates would have
little direct effect on the prices of services. The
strong response for price indexes based on services may reflect indirect effects from exchange rate
changes to wages, interest rates, or aggregate
demand conditions.
Our results confirm that the lags in question are
fairly long. For all three series, over half of the total
cumulative change in prices comes more than a
year following the exchange rate change, and
sizable effects occur even beyond two years.
Table 3 presents our results for the overall CPI
and compares them with results from other studies
that attempt to estimate the narrower structural
link between the dollar and U.S. prices. The other
studies hold constant, depending on the study,
such variables as real G N P , monetary policy, or
wages. Our results show by far the largest long-run
rise in the CPI following a depreciation of the
dollar.
All of the estimates in Table 3 are subject to
qualification. The various studies use data from
differenttime periods; if the relationship between
the dollar and prices changes through time, then
estimates based on one time period might not
apply to another time period. Secondly, all of the
estimates are based on assumptions about the
specification of the relationships in question,
such as lag structure for included variables and the
properties of the residual error term. In addition,
the single equation regression models and the
structural models require assumptions about
which possible explanatory variables to include
and which to exclude. Since there is no foolproof
method of testing for or eliminating specification
error, all of the estimates are subject to this source
of error. Finally, the estimates in the table are not
entirely comparable, because regression models
and the structural models attemptto estimate the
partial effect of the dollar on prices, holding constant other variables such as wages, monetary

FEDERAL RESERVE BANK OF ATLANTA




growth, or oil prices; moreover, different studies
hold different variables constant. By contrast, our
time series analysis attempts to estimate the price
response to dollar movements during our sample
period through all effective channels, without
holding other variables constant.
Since the end of our sample period, the dollar
has depreciated considerably. If the dollar were
the only determinant of inflation, our estimate
would suggest that a substantial pickup in inflation is likely in the next year or two. The other
studies in Table 3 suggest a significant but more
modest pickup in inflation, while the estimates of
W o o and Glassman would suggest no perceptible
response. However, other factors suggest a more
sanguine outlook for inflation. In particular, compared to the episodes of depreciation during the
1970s, the recent depreciation has coincided
with a period of relatively weak economic activity
in the world as a whole, as well as of weak and
even declining prices of raw materials, especially
oil. Nevertheless, based on our results, w e are
inclined to think that the other estimates in the
table, and especially those by W o o and Glassman
which find essentially no price response to changes
in the dollar, may understate the price response to
the dollar.17

Conclusion
The exchange value of the dollar has fluctuated
considerably in recent years. Most previous studies of the link between the dollar and prices find
that dollar depreciation has a modest but significant impact on inflation, though two recent studies suggest no impact. Our own findings indicate
that during the sample period studied, exchange
rate movements were followed by substantial
changes in the price level. Indeed, our results suggest that, if anything, the majority of previous
studies may have understated the inflationary response following dollar depreciation. Moreover,
there were long lags between changes in the
dollar and the associated changes in prices. If
these historical patterns persist, then progress
toward a policy goal of price stability may be
incompatible with a continuation of wide fluctuations in the value of the dollar.

3 For

Our results based on the univariate residual cross-correlation
functions and Granger tests indicate substantive relationships in which the dollar leads prices over long distributed
lags. The corresponding cross-correlation functions reveal
that the first few coefficients in these distributed lags are often
positive, while the next twelve to twenty-four coefficients are
mostly negative. The Granger tests reveal no empirical support for the alternative hypothesis that movements in prices
lead the dollar.
In terms of equations (1 ) and (2), these results indicate that
all of the b k 's are approximately zero but that at least some of
the a ^ s are different from zero. Therefore, w e confine our
attention to estimating the coefficients in equation (1). Equation (1) w a s estimated using constraints suggested by the
specification test results. Leaving the contemporaneous coefficient and the first three monthly lag coefficients unconstrained (because some of the first few cross-correlations
were positive), w e restricted the remaining coefficients to lie
along a damped polynomial, the "modified Almon lag" proposed by P. Schmidt [Schmidt (1974), G. S . Maddala (1977)
pp. 363-364], This lag structure combines an Almon lag with a
Koyck lag, allowing the polynomial portion implied by the
Almon lag to dominate over the first several coefficients, while
the Koyck lag eventually damps the coefficients toward zero.
The noise model for n 1 t is estimated simultaneously to enable consistent and asymptotically efficient estimation of
equation (1 ); see Box and Jenkins (1976), pp. 388-395. For
further details on the estimating procedures, s e e Koch,
Rosensweig, and Whitt (1986).
The estimated distributed lag coefficients, a k ; k = 0,1,2,...,
fortheoverall C P I are plotted in the first frame of Figure2. In the
k

second frame, the cumulative sum of coefficients, I

i=o

aj, is plot-

ted for k=0,1,2,... 60. This quantity represents the cumulative
response after k months in the C P I following a sustained one
percent increase in the value of the dollar. The contemporaneous and first three lagged coefficients are all positive,
as suggested by the cross-correlation function, though only
the coefficient at lag two months is statistically significant at
the .05 level. The coefficients beyond lag three months are all
negative. The cumulative sum of the coefficients turns negative beyond lag four months and grows toward an eventual
sum of approximately -.485.
Table 2 gives the cumulative sum of the coefficients at
various lags for all our price series. For the CPI, the sum
through twelve monthly lags is -.16; through twenty-four
lags, -.34; through thirty-six lags, -.43; and the infinite sum
converges to approximately -.485.

E. P. Box and G. M. Jenkins (1976) provide a useful introduction
to time series analysis. The use of time series methods in macroeconomics is somewhat controversial; for a critical analysis see
T. F. Cooley and S. F. LeRoy (1985).

d e p r e c i a t i o n of the dollar corresponds to a fall in this index. W e
have also employed the Morgan Guaranty dollar index in this
analysis, with robust results. For more details on the construction
and rationales for these and other indexes of the value of the dollar,
see D. Deephouse (1985) and J. A. Rosensweig (1986).
11 The

data for e t and p t often display trends and systematic seasonal
movements, implying nonstationarity. This problem is addressed
by detrending and deseasonalizing each series with a time trend
and eleven seasonal dummies in the regression models. The
results may then be interpreted as the relationships between the
dollar and prices, abstracting from systematic movements due to
trend and seasonality.
W e have also estimated the relationship between e, and p 1 t
using two other common methods to account for the nonstationarity implied by trend and seasonality: (i) take the first log
difference of each variable and include eleven seasonal dummies
in the distributed lag model; (ii) take a first and a twelfth difference
on the log of the data, before estimating the time series model.
W e prefer to employ the levels of e, and p lt rather than their first
or twelfth differences, since it is the relationship between their
levels that concerns us. Hence, the method outlined in the text is
preferred to those listed here. The distributed lag relationships are
found to be robust, regardless of the method used.

12 ln

particular, the random error term is not restricted to be a white
noise process. In the case of the estimated model for p, t , the best
model for the random error term is a fairly complicated MA
process.

13 To

do this, univariate Box-Jenkins models are first estimated
separately for p, and e t ; the residuals from these models are then
calculated; and finally, the cross-correlation function between the
two sets of residuals is obtained.

line for lag zero in the middle of Figure 1 gives the contemporaneous correlation, which is not significantly different from
zero.

because of measurement error. For instance, if import prices are

Nonbank Activities and Risk
Non bank subsidiaries have become
an increasingly attractive investment
choice for bank holding
companies,
but regulators are concerned about
the possibility of new risks.
Larry D. Wall

The number of bank holding companies (BHCs)
with nonbank affiliates has grown dramatically
since 1976, especially among BHCs with assets in
excess of $10 billion. Whatever the risks involved
in nonbank activities (such as mortgages, consumer financing, and data processing), bankers
apparently see potential for gain. Regulators,
however, must watch the financial condition of
BHCs closely because of the effect the parent
company can have on its bank subsidiaries. Financial problems at the bank holding company level
can endanger affiliated banks.
How do nonbank affiliates affect the stability
and profitability of BHCs? Existing regulation of
BHC activities and regulators' inquiries into further risk-based capital regulation assume that
nonbanks could increase an organization's riskiness, but the relationship between nonbank activities and increased risk is by no means clear-cut.
Even though existing nonbank subsidiaries may
be riskier than their bank affiliates, this does not

necessarily imply that the nonbank subsidiaries
increase the riskiness of the holding company. It is
possible that gains from diversification of an
organization's portfolio, especially geographic
diversification, could actually reduce B H C risk. In
either case, the potential effect of nonbank subsidiaries on BHC risk may have important implications for the regulation of BHCs.
If nonbank activities make BHCs riskier, then
regulators might want to require BHCs with nonbank subsidiaries to hold higher levels of capital.
Currently both banks and BHCs must maintain
primary capital equal to 5.5 percent of their
assets.1 Since not all assets are equally risky and
not all the risks taken by the bank are reflected on
its balance sheet, the Board of Governors of the
Federal Reseive System has proposed supplemental guidelines that include adjustments for
the riskiness of on- and off-balance sheet items.2
Although this proposal does not differentiate
between bank and nonbank subsidiaries of the
BHC, the Board recognizes that nonbank affiliates could add to an organization's risk and recently requested comments on a proposal to establish a new risk category that would " t a k e
account of the higher risks associated with certain
nonbanking activities
"3
If, on the other hand, nonbanks reduce B H C
risk, then perhaps regulations limiting the type of
activities that can be undertaken by BHCs could
be relaxed. Current regulations confine the domestic involvement of BHCs' nonbank subsidiaries to activities closely related to banking.
Practically speaking these nonbanks are restricted
to the same kind of activities allowed to banks. In
spite of these restrictions on nonbank activities,
nonbank subsidiaries may be reducing B H C risk
by providing greater geographic distribution than
is permitted for banks. Proponents of deregulation contend that diversification into currently
prohibited activities would reduce risk by allowing even greater diversification.4 Opponents contend that many activities considered for deregulation, such as investment banking, are far
riskier than commercial banking and would tend
to increase the riskiness of BHCs. 5
This study finds that the importance of nonbank subsidiaries for BHCs increased markedly
during the period from 1976 to 1984 (Chart 1).
M o r e BHCs invested in nonbank subsidiaries,
especially those BHCs with assets in excess of
$10 billion.
These results also show that nonbank subsidiaries are generally less profitable than their
20




banking affiliates. Indications of lower profitability combined with other studies' findings
that nonbank subsidiaries are riskier may seem
to suggest that nonbank subsidiaries weaken the
performance of BHCs. However, this conclusion
must be balanced by consideration of the effect
of nonbank activities on diversification.
Two recent studies find that on average nonbank subsidiaries may tend to reduce the riskiness
of BHCs slightly. Another study suggests on the
contrary that investment in nonbank subsidiaries
is associated with increased B H C risk. In the
analysis presented here, however, the effect of
nonbank subsidiaries on overall B H C profitability
as measured by consolidated return on equity
appears to be small. This research also concludes
that while nonbank subsidiaries may be associated
with increased risk, this does not imply that nonbank subsidiaries cause BHCs to be riskier. Even
given the correlation between nonbanks and
risk, it is possible that nonbanks have no effect on
BHC risk or actually reduce risk.
The implications of this andother studies is that
nonbank subsidiaries should be considered in
risk-based capital regulation. However, riskbased capital regulation should take account
not only of the stand-alone riskiness of nonbank
activities but also their effect on B H C diversification. These findings are neutral for deregulation.
Although nonbank subsidiaries do not significantly
increase risk, neither do they decrease it sufficiently
to support deregulation.

W h y the Concern About B H C Risk?
Bank holding companies are not regulated out
of concern forthe financial condition of BHCs per
se but rather because a B H C s financial problems
can affect its subsidiary banks. Not only is a subsidiary influenced by the overall financial condition of its parent BHC, but it can also be exposed
to losses if other affiliates of its B H C fail.
O n e way to protect subsidiary banks would be
to impose regulations that would prevent banks
from sharing in the losses of their affiliates. Then,
since the financial problems and failures of its
nonbank affiliates would not influence the financial condition of other bank subsidiaries, regulations designed to protect the safety and soundness of the BHC, such as capital regulation and
limits on permissible activities, could be eliminated, according to some analysts.6
Others claim that even though the current system attempts to protect banks from problems in
OCTOBER 1986, E C O N O M I C REVIEW

their nonbank affiliates through regulations that
limit a bank's ability to transfer resources to B H C
affiliates, including limits on dividends and loans
to affiliates, additional restrictions may be needed.
According to Robert Eisenbeis (1983) and Larry
Wall (1984), although existing guidelines reduce a
BHC's ability to use its banking subsidiaries to
help nonbank affiliates, regulations may not be
sufficient to prevent a transfer of resources. Banks
may, for example, attempt to aid their financially
troubled B H C parent or their nonbank affiliates in
order to protect the good name of the bank, or
because the management of the BHC controls the
management of its subsidiary banks. (Often times
the same individuals manage the B H C and the
bank.) Even if a bank could not transfer any resources, it would still be vulnerable to the failure
of its nonbank affiliates if it depended on them for
vital services or if the affiliate's failure impaired
the public's image of the bank.7 Anthony Cornyn
and others (1986) review the evidence and contend that both B H C managers and the public
view BHCs as integrated entities with the health of
each subsidiary depending on the overall condition of the BHC. Eisenbeis suggests that the only
way to protect banking subsidiaries completely
from problems in their nonbanking subsidiaries
would be to require the BHC to operate as a
passive portfolio manager. He notes that doing so
would, however, eliminate the advantages of
banks' affiliation with BHCs. 8

Nonbank Risk in a Larger Context

^ 2 9 8

The most obvious way of analyzing the effect of
nonbank subsidiaries on the stability of BHCs and
their banking subsidiaries is to examine the activity's expected return and the variability of its
return. However, this simple approach to risk
measurement can be highly misleading unless
banks are financially isolated from their nonbank
affiliates. If transactions between bank and nonbank subsidiaries are permitted, then the riskiness
of an activity should be analyzed in terms of its
effect on the entire BHC's expected return and
variability of return. An activity that, in isolation,
appears to be relatively chancy may substantially
reduce a BHC's riskiness when the risk position of
the entire organization is taken into consideration.

285

Diversification. Diversification into a variety of
holdings or over a broad geographic area can
defuse risk, even when some of the individual

holdings themselves are risky. The misleading
nature of activity-by-activity analysis can be illustrated with a simple example. Suppose that
regulators are considering allowing a B H C to invest in three different assets: A, B, and C. Each of
the assets could yield one of six equally likely rate
of return outcomes, as presented in Table 1. For
example, a one-in-six probability exists that outcome 2 will occur, in which case asset A would
yield a return of 0 percent, asset B a 9 percent

return, and asset C a 4 percent return. The comparative merits of these assets can be examined
by looking at their profitability and riskiness. The
profitability of each asset is measured by its expected return and the riskiness is measured by the
standard deviation of its returns. (Higher values for
the standard deviation suggest greater risk.)
Assets A and B are relatively low risk assets, but B
offers a slightly higher expected return for a little
more risk. Asset C is substantially riskier and has a
somewhat higher expected return than either
asset A or B. If a banking organization were permitted to invest in only one asset, then asset C would
be the least desirable since it has a much higher
standard deviation and only a slightly larger expected return. However, asset C could be highly
desirable if a BHC were investing in a portfolio of
assets. The returns from a portfolio with equal
combinations of assets A and B are presented in
the fourth column. This limited portfolio results in
expected returns that are midway between the
returns of assets A and B and a standard deviation
lower than either asset A or asset B taken singly.
22




However, a portfolio of assets A, B, and C formed
with equal weights on all three assets produces
even better results. The expected return on the
three-asset portfolio is slightly greater than on the
two-asset portfolio, and the standard deviation of
returns on the three-asset portfolio is substantially
lower—0.6 percent versus 3.7 percent. Thus, if our
hypothetical banking organization is allowed to
invest in more than one asset, then C should probably be permitted.
The effect of diversification is demonstrated
more generally in Figure I. 9 The vertical axis on
Figure 1 represents an asset's expected return,
and the horizontal axis measures the standard
deviation of the return. The dots in Figure 1 represent different assets, such as bank assets or the
sort of stocks and bonds individuals might invest
in. If an investor purchased only one asset, he
could expect the riskand return associated with
the individual dot he chooses. However, if the
investor purchased a portfolio of several assets,
then the potential combinations of risk and return
would include all the combinations in the circle.

Figure 1.
Effect of Portfolio Diversification

Figure 2.
Benefits of Portfolio Expansion

Through diversification
an investor expands the options for combinations
of risk and returns from one
dot (representing
a single asset) to all the dots or
combinations
in the circle.

Investors seeking the maximum return for the
minimum risk will select a point on the upper lefthand side of the circle, the efficient frontier, as
these points are superior to other alternatives.
The effect of expanding the list of assets available to an investor can be seen in Figure 2. The
inner circle represents the choices available when
tight controls are placed on permissible assets;
the outer circle represents the choices when the
list of permissible assets is expanded. The exact
placement of the two circles depends on the particular assets under consideration. However, expanding the list of permissible assets can never
shrink the circle, because investors can always
choose to ignore assets on the expanded list.
Figure 2 illustrates that wider asset selection is
always preferable. Suppose for instance that an
investor initially constrained to the inner circle
chose his assets so that he would obtain the risk
and return at point a. W h e n the list of assets is
expanded, the investor can choose to maintain
the same return while reducing his risk through
diversification (point b) or he can maintain the
same risk and receive a higher return through
diversification (point c).
Management Influences. Portfolio theory is
inadequate by itself to determine the effect of
BHCs, according to Stephen A. Rhoades (1985).
The discussion of diversification implied that the
efficient frontier is dictated solely by the restrictions on BHC assets, but in fact the way assets are
managed significantly affects the location and

of

shape of the efficient frontier. Furthermore,
management's choice of a portfolio will determine which point on the new efficient frontier an
organization selects—one with less risk or greater
profit—when the list of potential assets is expanded.
Incompetent management and weak internal
controls can increase the level of risk for any given
return, while good management with strong internal controls can decrease the risk for any given
level of returns. Management's strategy, as well as
its quality, can influence the efficient frontier.
Some managers may choose to run a tightly controlled organization to promote cooperation
among its subsidiaries, while other BHCs may
allow their subsidiaries to operate with relative
independence so that they can respond to conditions in their individual markets. W h i c h strategy
will produce the most desirable efficient frontier
is debatable; but, in any event, the location of the
frontier is likely to change depending on management's strategy.
Figure 2 demonstrates how management can
control the location of its organization on the efficient frontier. Suppose that a B H C is at point a
23

prior to deregulation. After deregulation it could
move to point b, which has lower risk forthe same
return, or to point c, which has the same risk with
higher return, or to some point in between.
However, there is no requirement that the B H C lie
somewhere between points b and c on the new
frontier. Management could choose a portfolio
that lies at point d on the curve, a position with
greater returns and greater risks, or point e, with
lower returns and lower risks.
W h e t h e r or not management would use nonbank subsidiaries to increase a BHC's risk exposure is an empirical question. Regulators are
concerned that because FDIC deposit insurance
removes some of the negative incentives to increased risk-taking, management will use nonbank subsidiaries to increase risk exposure.
However, nonbank subsidiaries are not the only
way to increase risk; if managed properly (or improperly) traditional banking activities, too, can
be extremely risky.10 For example, banks can
already make or lose substantial sums of money in
commercial lending.

H o w Profitable are Nonbanks?
Before considering the impact of nonbanks on
B H C risk, it is important to consider the profitability of nonbank subsidiaries and their effect
on the financial condition of parent BHCs. A look
at the data from 1976 to 1984 shows that investment in nonbanks has grown dramatically among
BHCs with assets greater than $10 billion. Even
though the percent invested in nonbanks has
shrunkamongsmaller BHCs—those with assets of
under $1 billion and those with assets between $1
billion and $10 billion—the number of BHCs with
nonbank subsidiaries has increased across the
board (Table 2).11 This suggests that for whatever
reason, BHCs find nonbanks attractive. The analysis in this study indicates that nonbank subsidiaries are more profitable for BHCs with assets
over $10 billion.

Examining the extent of B H C investment in
nonbanks and the profitability of bank and nonbank subsidiaries, as well as parent BHCs, may
offer some insight into the role of nonbanks in
B H C investment strategies. Extending previous
studies, this research includes all BHCs with positive investments in nonbanks, examines time
trends, and splits the sample into three subsamples based on B H C size.12
B H C involvement in nonbank activities is
measured in two ways: first, the number of BHCs
24




with positive investment in nonbanking subsidiaries and, second, median B H C investment in
nonbanking subsidiaries as a percentage of total
B H C investment in subsidiaries. The number of
BHCs with positive investment in nonbank subsidiaries is increasing for all three size categories.
BHCs with consolidated assets of less than $1
billion showed the largest increase in the number
of BHCs with nonbank subsidiaries. The number
of nonbank subsidiaries and BHCs with consolidated assets in excess of $10 billion doubled
over the nine-year period of the study.
The numbers in Table 2 cannot be used to
determine the number of BHCs starting nonbank
activities in each of the three size categories. The
change in the total numberof BHCs with nonbank
activities does not reflect the total number of
BHCs starting nonbank subsidiaries, because the
acquisition of one B H C with nonbank affiliates by
another with nonbank subsidiaries reduces the
number of BHCs reporting nonbank activities. In
the smallest size category, the change in the
number of BHCs with nonbank activities is also
less than the number of small BHCs starting nonbank activities, because some BHCs with nonbank activities shifted size categories as a result of
asset growth. Similarly, in the case of BHCs with
assets in excess of $10 billion, the change may be
greater than the number of BHCs starting nonbank operations because some of the increase
reflects the fact that smaller BHCs have changed
categories due to asset growth.
Median parent BHC investment in nonbank
subsidiaries as a proportion of total parent investment in subsidiaries varies across the different
size categories in recent years (Table 3).13 Median
proportion of investment in nonbank subsidiaries
by all three size categories was small in 1976 with
the largest BHCs having the smallest proportion.
W h i l e the median proportion has fallen since
1976 for BHCs with assets below $10 billion, it has
increased dramatically forthe largest BHCs, jumping from 1.8 percent in 1976 to 12.2 percent in
1984.

The returns for nonbank subsidiaries, banking
subsidiaries, and consolidated BHCs are provided
for each of the nine years in Tables 4-6. Before
examining the results, however, several points
need to be made about the data. First, any study
that uses accounting data from corporations
owned by other corporations must implicitly assume that the reported income is an accurate
reflection of economic values and that the parent
company is not manipulating interaffiliate transfer

pricing to shift reported income from one subsidiary to another.14 This assumption is not subject to directtesting, because the fair market value
of interaffiliate transactions is not observable. If
shifting does, however, bias the reported figures
of BHC subsidiaries, it may be toward lower bank
riskand highernonbankrisk, since bank regulators
are more concerned about the safety of bank subsidiaries than that of nonbank ones.

Second, any study that uses consolidated B H C
figures will reflect not only the results of operations among the bank and nonbank subsidiaries,
but also those of the B H C parent. The profitability
of services provided by the B H C parent must be
considered as a relatively minor influence. BHC
parents typically place most of the service functions in their subsidiaries so that the parent has
few employees and minimal assets. A more significant influence is B H C double leverage practices: some parent BHCs have a greater investment in their subsidiaries' equity capital than they
have equity capital of their own, and they fund the
excess with debt issues. This double leverage
results in both reduced net income and reduced
equity for the consolidated BHC.
A third consideration is that a subsidiary and
BHC parent may report different figures for income and equity in cases in which the subsidiary
is accounted for by the BHC parent through the
purchase method of accounting. Then the income
will generally be lower and the equity greater on
the books of the parent BHC than on the books of
the subsidiary for several years after the acquisition. The purchase method of accounting is required when one company acquires another and
the transaction is paid for primarily with cash or
debt. This method is not used for de novo subsidiaries created by the BHC, nor is it allowed for
acquisitions financed exclusively by stock of the
acquiring organization. The direction and extent
of this distortion is hard to measure since it
depends on how many subsidiaries each B H C has
acquired, how much they are worth, and on the
method used to finance the acquisitions. This
consideration is an important one for any study
that calculates return on investment using data
from the parent company.
Given these caveats, an examination of the data
shows that the median return on parent investment in nonbank subsidiaries is consistently
below that of the return on banking subsidiaries
for the smallest BHCs (Table 4). In some cases,
such as 1982, the return on the nonbank subsidiaries was less than half that of the banking subsidiaries. Furthermore, the lower median returns
FEDERAL RESERVE BANK OF ATLANTA




for nonbank subsidiaries are reflected in median
returns that are lower for the consolidated BHCs
than for BHCs investing in bank subsidiaries.
One possible explanation for the results in the
category for the smallest BHCs is that nonbank
subsidiaries are inherently less profitable. This
explanation implies that the proportion of B H C
investment in nonbanking activities is falling
because small organizations are reducing their
exposure to less profitable activities. However,
the increase in the number of small BHCs with
nonbank subsidiaries appears to contradict this
hypothesis, suggesting that smaller BHCs find
nonbank activities desirable (Table 2). An alternative reason for the low profitability could be that
many small banking organizations are opening de
novo nonbank subsidiaries. Then the low profitability of the de novo subsidiaries would be
reducing the median profitability of all the subsidiaries, and the small size of the new subsidiaries
would be reducingthe median proportion of BHC
investment in nonbanking subsidiaries. Another
explanation is that many of the new nonbank subsidiaries may have been organized to provide services to their B H C affiliates. In this case the parent
organization might not be concerned about the
profitability of the nonbank activities, since the
nonbank subsidiary's profits would be earned at
the expense of the other subsidiaries.
For the intermediate size B H C (consolidated
assets between $1 billion and $10 billion), median nonbank subsidiaries appear to be somewhat less profitable than the median banking
subsidiaries. The gap is narrower in the 1980s,
though, than it was in the 1970s (Table 5). Nonbank subsidiaries helped make the median return
on equity of consolidated BHCs somewhat lower
than the median return for the BHCs' banking
subsidiaries.

The nonbank subsidiaries of the largest BHCs
have been the most successful (Table 6). Although
their median return is generally below that of the
banking subsidiaries, the difference is less than
in either of the two smaller size categories, and
the return on equity for the consolidated BHC is
above that of its banking subsidiaries. This result
could, as previously mentioned, reflect double
leveraging practices by the BHCs.
Nonbanking subsidiaries of BHCs with total
assets below $1 billion, then, reported much
lower returns than did their banking affiliates. The
nonbank subsidiaries of BHCs with assets above
$1 billion did betterand the nonbank subsidiaries
of BHCs with assets greater than $10 billion came
closest to matching banking affiliates.
27

Determining Risk: Some Prior Studies
W h i l e the potential benefits of BHC diversification into currently permissible activities and impermissible activities has been demonstrated by
several studies, the actual effect of existing nonbank subsidiaries has received less attention. 15 A
look at some prior studies of risk helps put the
research presented here into perspective. Examining bond market reactions to bank acquisitions
of discount brokers, Wall and Eisenbeis (1984)
found that bond returns were not significantly
affected by B H C diversification into discount
brokerage. B H C diversification into discount
brokerage, then, does not significantly affect the
market's perception of the riskiness of a BHC.
However, the Wall and Eisenbeis study is limited
in that it only considers BHC diversification into
discount brokers and does not analyze performance after acquisition.
To analyze the effect of nonbank subsidiaries
on the risk of capital impairment among BHCs
(defined as the probability that cash flows from
operations will be less than debt service costs),
David R. Meinster and Rodney D. Johnson (1979)
developed a special methodology and applied it
to determine the impact of nonbank subsidiaries
on First Pennsylvania Corporation and Philadelphia National Corporation over the period from
the first quarter of 1973 to the third quarter of
1977. They found that nonbank subsidiaries reduced the riskiness of the BHCs they analyzed,
but that the financial practices of BHCs caused the
consolidated organizations to be slightly riskier
than their banking subsidiaries.16 Meinster and
Johnson provide a comprehensive examination
of the effect of nonbank subsidiaries on BHC risk,
but it applies to only two BHCs. This study also
depends on the assumption that BHCs do not
shift income between bank and nonbank subsidiaries.
O n e study finds that BHCs are less risky than
their subsidiary banks. Robert E. Litan (1985)
examined the mean and coefficient of variation of
after-tax earnings as a percentage of assets for 31
large banking organizations over the period from
1978 to 1983 to measure the riskiness of a firm's
earnings.17 He found that the bank holding companies had higher mean returns and lower coefficients of variation of returns—implying lower
risk—than their banking subsidiaries. However,
Litan notes that the bank holding companies are
less risky than their bank subsidiaries for only 16 of
the 31 banking organizations in his sample.
28




Litan worked with a largersample than Meinster
and Johnson, but his sample was still a relatively
small proportion of the total number of BHCs with
nonbank subsidiaries. (The sample does, however, include the holding companies that are
likely to have the largest nonbank subsidiaries.)
Litan shares with Meinster and Johnson the implicit assumption that the reported income of
banking subsidiaries is an accurate reflection of
economic income, and his results may also reflect
B H C parent activities and double leverage practices.
In a study that examined the risk of failure
(defined as losses in excess of capital) for banking
subsidiaries, nonbanking subsidiaries, the combination of bankand nonbankingsubsidiaries,and
the consolidated B H C over the period from 1976
to 1984, Larry D. Wall (1986) found that nonbank
subsidiaries did not increase the riskiness of BHCs
and may have caused slight reductions in their
riskiness. All BHCs that had nonbank subsidiaries
at least six of the nine sample years were included
in the analysis. Using data on BHC parent return
on investment in subsidiaries for the B H C parent,
the study found that nonbank subsidiaries by
themselves are indeed much riskier than the
banking subsidiaries. However, nonbank subsidiaries provided diversification benefits such
that combining bank and nonbank subsidiaries
caused a small, statistically insignificant, reduction in the risk of failure on average. Using a contingency table approach to provide statistically
significant evidence that nonbank subsidiaries are
risk-moderating, the study indicated that nonbank subsidiaries tended to decrease the riskiness of high-risk BHCs and increase the riskiness
of low-risk organizations.18
Although it is more comprehensive than the
other studies, the Wall (1986) study, like the previous two, assumes that reported income is not
distorted by interaffiliate transactions. In the Wall
study, however, interaffiliate transactions are assumed to bias the results towards nonbanks
increasing risk, whereas all three studies using
accounting data found evidence for a slight risk
reduction. Wall's results may also be influenced
by B H C parent activities and double leverage
practices. The study uses subsidiary income and
equity as repotted by the BHC parent, and the
figures could differ from those recorded on the
subsidiaries' accounting records.
In a study that seems to contradict Wall's 1986
research, John H. Boyd and Stanley L. Graham
(1986) show that the risk of failure for a BHC is

significantly positively related to its involvement
in nonbank activities over the period 1971 to
1977. Their sample consisted of all domestic
BHCs with total assets exceeding $5 billion at the
end of 1983, except for six deleted due to missing
data or special Federal Deposit Insurance Corporation involvement during the sample period.
The study obtains its results by gauging a BHC's zscore (the sum of expected return on assets and
the capital-to-asset ratio divided by the standard
deviation of return on assets) against two measures of nonbank activity, the BHC's debt-toassets ratio and the log of its total assets. Neither
measure of nonbank activity matched exactly
with the percentage of B H C assets devoted to
nonbank activities, but both are highly correlated
with B H C investment in nonbank subsidiaries as a
percentage of total investment in subsidiaries
over the 1976 to 1983 period. Boyd and Graham
also found that the proportion of nonbank activities does not have a statistically significant
effect over the full sample period from 1971 to
1983 or the subperiod from 1978 to 1983. They
note that the Federal Reserve phased in a "goslow" policy towards new nonbank subsidiaries
beginning in 1974, and they assert that this policy
was the primary cause for the difference in results
between the 1971 to 1977 subperiod and the
1978to 1983 subperiod. Thus, they conclude that
"when management was left more to its own
devices, those BHCs with above-average nonbank activity also exhibited above-average risk."19
This suggests that careful regulation of BHC expansion may be appropriate.
The results of the Boyd and Graham study may
reflect BHC parent activities and double leverage,
but unlike the other studies using accounting
data, Boyd and Graham's results cannot be biased
by interaffiliate transactions. However, the study's
findingthat nonbank activities are associated with
greater B H C risk is consistent with several different interpretations that could reflect three very
different explanations: nonbanks causean overall
increase in a BHC's riskof failure; nonbanks do not
change the overall riskoffailure of BHCs;and nonbank subsidiaries cause a decrease in the overall
risk of failure of BHCs.
For example, the first explanation, that nonbank subsidiaries cause an increase in risk, could
be interpreted as an indication that at least some
BHCs cannot attain their desired risk level with
their traditional banking subsidiaries. Nonbank
subsidiaries enable BHCs to increase their risk
because they allow expansion into the riskier
FEDERAL RESERVE BANK OF ATLANTA




aspects of banking and because nonbank subsidiaries are less tightly regulated than bank subsidiaries. This interpretation raises some concern
about additional deregulation of activities, since
BHCs could use expanded powers in nonbank
activities to become riskier. The hypothesis that
nonbank subsidiaries cause an increase in BHC
risk is inconsistent with the findings of Litan and
Wall showing that BHCs are slightly less risky than
banking subsidiaries, and with Wall's finding that
nonbank subsidiaries are risk-reducing.
An interpretation consistent with the risk neutrality explanation is that greater nonbank activity
is a sign of lower BHC risk aversion, but that nonbank subsidiaries do not cause an increase in
overall BHC risk of failure. In this case the bank
affiliates are often riskier than the nonbank subsidiaries. Management may invest in nonbank
subsidiaries because the long-run risk/return
reward is more favorable. This interpretation is not
favorable for deregulation, because it suggests
that BHCs may not use expanded powers to reduce risk through diversification. However, it may
not be as unfavorable for diversification as the first
interpretation since it allows for the possibility
that BHCs will be able to attain their desired risk
level with traditional banking services, thus implying that further deregulation will not automatically
result in BHCs becoming riskier. This interpretation of Boyd and Graham's results does not
necessarily conflict with Litan's and Wall's evidence that BHCs are less risky than banks, because both of those studies found that the difference between the riskiness of banks and BHCs
is small.
An interpretation consistent with the risk reduction explanation is that BHCs with the riskiest
banks are investing in nonbank subsidiaries to
reduce risk through diversification. For example,
geographic restrictions on bank operations may
not allow a BHC to obtain adequate geographic
diversification. In this case the positive relationship between B H C risk and level of nonbank
activities observed by Boyd and Graham occurs
because existing nonbank subsidiaries are not
sufficient to obviate the risk created by the banking subsidiaries. This interpretation of the risk
reduction explanation suggests that deregulation
of BHC activities could reduce the riskiness of
banking organizations.

The risk reduction interpretation is not consistent with Boyd and Graham's suggestion that the
differences in results between the two subperiods were due to changes in Federal Reserve
29

policy. However, their study does not test the role
of Federal Reserve BHC regulatory policy, and the
possibility exists that the results could be traced
to other factors such as disparities in the economic conditions between 1971-77 and 197883.20
Thus, even though Boyd and Graham's findings
seem to suggest that deregulation could lead to
increased risk-taking, their results can be interpreted in several ways and are not necessarily
inconsistent with nonbanks' having a risk-reducing influence. The results of Litan and Wall could
also be interpreted as supporting this finding.
W h i l e the evidence seems to indicate that
existing nonbank subsidiaries can significantly
affect the riskiness of individual BHCs, whether or
not they have increased the overall riskiness of
banking organizations is less clear. Correlatingthe
results of the three major previous studies—Litan
(1985), Wall (1986), and Boyd and Graham (1986)—
suggests a likely hypothesis, however. Litan and
Wall found that nonbank subsidiaries may have
caused a small decline in average risk, but they
note that nonbank subsidiaries may have increased the riskiness of some BHCs. Boyd and
Graham find that B H C risk is positively associated
with its investment in nonbank activities, and one
interpretation of Boyd and Graham's results conflicts with Litan's and Wall's research, namely, that
nonbank subsidiaries cause BHCs to become
riskier. However, Litan's and Wall's findings are
consistent with two other interpretations of Boyd
and Graham's results: that nonbank subsidiaries
have a neutral effect on B H C risk orthat nonbanks
cause a reduction in B H C risk. Litan's and Wall's
results can be reconciled with those of Boyd and
Graham if nonbanks have a neutral or risk-reducing effect on BHC risk.

Do Nonbank Activities Increase B H C
Risk?
The hypothesis that nonbank activities have a
neutral or risk-reducing effect can be tested empirically. If nonbank activities are indeed risk-reducing or neutral with regard to risk, then the
relationship that Boyd and Graham observe between nonbank activity and BHC risk must exist
because (1) differences in the riskiness of the
banking subsidiaries cause differences in B H C risk
and (2) nonbank activity is positively correlated
with risk among banking subsidiaries. Both of
these relationships can be subjected to empirical
30




tests. If either condition does not exist, the risk
neutrality and risk reduction explanations for
Boyd and Graham's findings would be doubtful.
Before going to the empirical analysis one note of
caution is necessary. Failure to find significant relationships may suggest rejection of the risk
neutrality and risk reduction hypothesis. The existence of significant relationships, however, is not
by itself grounds for rejecting the interpretation
that nonbank activities cause BHCs to be riskier.
There is no logical inconsistency between nonbank subsidiaries causing greater B H C risk and,
either (1 ) bank subsidiaries being associated with
greater B H C risk or (2) nonbank activity being
positively correlated with bank risk.

Empirical Analysis
The following empirical analysis uses Wall's
sample of 267 BHCs reporting positive investment in nonbank subsidiaries for six of the nine
years from 1976 to 1984. The data is from parent
and consolidated BHC financial statements filed
with the Federal Reserve (FRY-6 and FRY-9). The
advantage of using FRY-6 and FRY-9 is that it
makes possible the calculation of the risk of
failure among bank subsidiaries, nonbank subsidiaries, and the consolidated BHC. It also provides information on BHC investment in nonbank
subsidiaries. A potential problem with FRY-6 and
FRY-9 is that reliable data begins only in 1976.
However, Boyd and Graham did not find a significant relationship between the proportion of B H C
investment in nonbank activities between 1978
and 1983. Their finding of a relationship between
the proportion of BHC investment in nonbank
activities and B H C risk must be replicated with
Wall's sample before the explanations of Boyd and
Graham's results can be considered. All three
limitations of the FRY-6 and FRY-9 data noted in
the discussion of nonbank profitability also apply
to this analysis: (1) reported income of bank and
nonbank subsidiaries will depend on the pricing
of interaffiliate transactions; (2) BHC parent activities and double leverage policies will influence
reported consolidated income and equity; and
(3) the reported income and equity of subsidiaries
acquired via the purchase method of accounting
may not be the same on the parent B H C s books
as it is on the subsidiaries' financial statements.21
The risk variable used is a measure of the possibility that losses will exceed expected income

plus capital. The measure is defined as
g' = (1 + m) / s
where
g' = risk measure
m = mean return on equity over the
period from 1976 to 198422
s

= standard deviation of return on equity
over the period from 1976 to 1984.

This risk measure is similar to Boyd and Graham's
z-score. The primary difference is that the z-score
is based on return on assets rather than return on
equity. The g' measure is inversely related to B H C
risk, higher levels of g' implying lower risk. Following Boyd and Graham, leverage is defined as consolidated B H C debt divided by consolidated
assets, and the size variable is the logarithm of consolidated BHC assets.
The empirical technique used to analyze the
data is calculation of rank order correlations between the different variables. Regression analysis
and commonly used correlation techniques assume a linear relationship between the variables
of interest. However, it is highly unlikely that the
risk measure used by this study is linearly related
to the probability of failure. Rank order correlation
eliminates the need to assume a linear relationship between the variables. The only assumption
FEDERAL RESERVE BANK OF ATLANTA




required for rank order correlation is that the risk
measure be able to rank BHCs from the riskiest to
the least risky. The principal disadvantage of this
technique is that it does not allow risk to be
regressed on three independent variables, so that
only one pair of variables can be analyzed at a
time.
The correlation coefficients measure the closeness of the relationship between two sets of rankings. The coefficients may range between -1 and
+ 1. A coefficient of +1 indicates that the highest
value in one ranking is associated with the highest
value in the other ranking, second highest with
second highest, third highest with third highest,
and so forth. A value of -1 indicates a perfect
inverse relationship between the rankings, and a
value of zero implies no relationship between the
rankings. The figure in parentheses gives the probability that the true rank order correlation coefficient is equal to zero, that is, the probability that
no relationship exists between the variables. The
closerthe number in parentheses is to zero, then,
the more significant the correlation. In Table 7 w e
see the strongest correlation, 0.6612 with a significance level of 0.0010, between the risk measure of consolidated BHCs and the risk measure of
bank subsidiaries. Another strong correlation,
0.3295 with a significance level of 0.0010, exists
between the leverage ratio and the log of total
B H C assets.
31

The rank order correlations in Table 7 are similar
to Boyd and Graham's regression results for the
1971 to 1977 subperiod. BHC risk is directly related to B H C nonbank activity and leverage, and
inversely related to the logarithm of total B H C
assets (recall that g' is inversely related to risk).
Thus, these data may be able to offer evidence
supporting or rejecting the risk neutrality and risk
aversion explanations.

The results of these tests do not reject the risk
neutrality and risk reduction interpretation of
Boyd and Graham's results. The riskiness of the
banking subsidiaries is positively correlated with
the riskiness of the BHC, suggesting that the bank
subsidiaries may be the primary determinant of
BHC risk. Furthermore, B H C investment in nonbank activities is positively associated with the
riskiness of the banking subsidiaries. This suggests
that B H C investment in nonbank activities could
be the result of either management risk preferences or an attempt by management to diversify.
None of the otherempirical results (Table 7) can
be used to reject the risk increasing, risk reducing,
or risk neutrality interpretations. However, several
results provide interesting information on the risk
structure of BHCs. The positive relationship of
nonbank subsidiary risk with consolidated B H C
risk, BHC leverage, and banking subsidiary risk is
consistent with the possibility that management
preferences influence the riskiness of the BHC's
subsidiaries and determine the use of consolidated leverage to influence overall risk. The
negative relationship between percentage investment in nonbank subsidiaries and nonbank subsidiary risk suggests that nonbank performance
becomes more stable as the size of the subsidiaries increase.

Conclusion
Analysis of the contribution of nonbanks to the
financial performance of BHCs suggests that at
least some BHCs can gain from nonbank activities. The number of BHCs with nonbank subsidiaries has grown over the period from 1976 to
1984. The proportion of BHC investment in nonbank subsidiaries has increased markedly for
BHCs with assets in excess of $10 billion. W h i l e
the return on investment has been low for BHCs
with assets below $1 billion, the returns have
improved over the sample period for those with

32




assets between $1 and $10 billion and those with
assets greater than $10 billion.
Nevertheless, the riskiness of BHCs remains an
issue for regulators, who must be concerned not
only with the health of the B H C but with the
stability of subsidiary banks, which can be seriously affected by failures among their affiliates.
Advocates of deregulation suggest that nonbank
subsidiaries will reduce the riskiness of BHCs
through diversification. The opponents of deregulation claim that nonbank subsidiaries will
engage in high-risk activities that will increase the
riskiness of the parent BHC.

This research concludes that while there is
indeed a correlation between the proportion of
nonbank activity and B H C risk, this correlation
does not necessarily mean that nonbanks are the
cause of the increased risk. This correlation could
hold true even if nonbanks in fact decrease risk or
have no impact upon BHC risk whatsoever. A
composite of existing research, tested by empirical analysis, seems to support best the hypothesis that nonbanks either decrease BHC risk
slightly or have little impact.
Caution is nonetheless implied by the results of
these studies. Nonbank activities appear to increase the risk for some BHCs and decrease it for
others, indicating that the riskiness of nonbank
activities should be taken into consideration in
risk-based capital standards. Keep in mind, however, that nonbank subsidiaries should be analyzed in a portfolio context rather than on a
stand-alone basis, because activities that appear
highly risky in isolation could actually reduce the
overall risk of a BHC.

The indications for deregulation from studies of
existing nonbank subsidiaries are, then, neutral to
slightly unfavorable. Even though, according to
this interpretation of the research, nonbanks are
most likely to reduce BHC risk or leave it unaffected,
the observed risk reductions are sufficiently small
and the evidence is sufficiently ambiguous that
w e cannot count on deregulation to reduce significantly the riskiness of the banking system. Furthermore, the low profitability of some bank
subsidiaries could mean that nonbank activities
have an adverse affect on the profits of certain
BHCs. Thus, any deregulation of activities should
be accompanied by careful monitoring of new
nonbank subsidiaries.

2 Bank

activities that create risk for the bank but do not increase bank
assets are often referred to as off-balance sheet activities. An example
of an off-balance sheet activity is bank issuance of letters of credit to
corporations. When the bank issues a letter of credit it promises to lend
money to the corporation at the firm's discretion. However, both the
time period for the corporation to exercise its rights and the maximum
amount of the loan are limited. In return the corporation pays a fee to
the bank. Banks are assuming some risk with a letter of credit. The corporation may request a loan when it is having financial problems and
cannot obtain loans elsewhere. However, no asset has been created
on the bank's books until the corporation actually borrows money and,
therefore, the banking organization does not need to hold additional capital.

to deregulate B H C activities may also endanger the banking
system by limiting its ability to compete with nonbank firms. Banks
may lose market share and may even become obsolete if the selling of

Robert J. Lawrence (1985) suggests that banks could be
effectively insulated if they were in effect converted into mutual funds
with sharp limits on permissible investments.

^ h i s example is based on a theoretical study of portfolios by Harry
Markowitz (1952).
1 0 One

reason for believing that deregulation will increase the riskiness of
B H C s is that the regulators will be ineffective supervisors of nonbank
activities. Regulators understand the risks inherent in traditional banking activities and can therefore properly supervise these activities.
Some banks that would like to become riskier cannot because the
regulators stop them. However, the regulators may not understand the
risks inherent in some currently prohibited nonbanking activities (such
as automobile manufacturing or retailing). B H C s could take excessive
risks in nonbank affiliates without the regulators' recognizing the problem. Although this may be a legitimate concern, it does not necessarily imply that most nonbank activities must be prohibited. The
problem could be solved in a variety of ways; for example, the
regulators could hire experts in nonbanking fields and cover any
additional costs by levying greater examination fees on to B H C s with
selected nonbanking activities.

Adi Kama (1979) for a discussion of nonbank subsidiary profitability in 1976.

source of the data is the "Bank Holding Company Financial Supplement" (FRY-9) for the period from 1975 to 1977 and the "Annual
Report of Domestic Bank Holding Companies" (FRY-6) for the 1978 to
1984 period.

13 Median

values are used rather than mean values to avoid distortions
caused by unusual values of some variables for certain BHCs. In particular the proportion of investment figures are heavily skewed by a
small number of B H C s with very substantial investment in nonbank
subsidiaries. Also the return on investment figures for some nonbank
subsidiaries have abnormally large absolute values, perhaps reflecting the fact that many of the nonbank affiliates are small in relation to
their BHC and also the fact that many nonbank operations incurred
significant start-up expenses.

14 This

consideration is not limited to analysis of B H C subsidiaries; it
applies to analysis of all corporations that are owned by other corporations.

example, see Arnold A. Heggestad (1976), Johnson and Meinster

when a B H C parent's equity investment in its subsidiaries exceeds the

possible way to avoid the problems created by purchase accounting would be to gather income and equity data from the individual subsidiaries. Unfortunately, the only comprehensive source of financial
information about individual nonbank subsidiaries of B H C s and about
B H C percentage ownership of bank subsidiaries is the "Annual
Report of Domestic Bank Holding Companies" (FRY-6) and that data
set cannot be used to aggregate partially owned subsidiaries. The
ownership figures on the Y-6 file contain numerous errors (such as
ownership percentages greater than 100 percent) and omissions.
Furthermore, the interpretation of the ownership figures is questionable for tiered BHCs. If a B H C owns 60 percent of subsidiary A and
subsidiary A owns 70 percent of subsidiary B, then the B H C s share of
B's earnings is 42 percent (60 percent times 70 percent). The Y-6 file
may show an ownership interest of 70 percent, however, to reflect the
fact that the B H C controls over half of B's stock.

The Changing Pattern of U.S. Trade: 1975 to 1985
Jeffrey A. Rosensweig, Gretchen Lium, and Kelly W e l c h
The trade deficit and the increasingly global nature of the economy often dominate in discussions of recent U.S. trade developments.
Frequently overlooked are significant changes in
the geographic pattern of U.S. trade over the last
few years. Since 1975 shares in the total dollar
value of our trade, our imports, our exports, and
our trade deficits have shifted away from the oilexporting countries and Latin America toward
Asia. Asia's increasing preeminence in trade applies not only to Japan but to developing nations
such as South Korea, Taiwan, and Singapore.
These shifts affect our analysis of the impact of
world events on the U.S. international trade situation and should be taken into account in evaluating the effectiveness of policies designed to
alleviate the trade deficit. To appreciate the implications of changes in geographic patterns of
U.S. trade, however, it is necessary to recognize
their magnitude.

Overall Trends in U.S. Trade
Despite talk about growing global economic
integration, total U.S. trade has remained relatively constant as a proportion of G N P since
1974.1 In current dollars, total trade more than
doubled, growing from $207 billion in 1975 to
$573 billion. Trade's share of G N P , however, increased only slightly between 1974 and 1980—
from 14.2 percent to 17.5 percent. By 1985 it had
declined to 14.4 percent.
Total trade figures, however, mask a drastic
change in the import-export trade mix. U.S. imports rose from just over $100 billion in 1975 to
over $360 billion in 1985, an average nominal
36




growth rate (not adjusted for changing prices)
exceeding 13 percent per annum. Export growth,
on the other hand, barely exceeded 7 percent per
annum, as exports rose from $107 billion to $ 213
billion. The much faster rate of growth in imports
has upset the balance of U.S. trade from a small
surplus in 1975 to a record deficit in 1985 of $148
billion (Chart 1).
In 1975 exports constituted 6.7 percent of
C N P , and imports represented a lower 6.6 percent share, signifying a small trade surplus. The
import share of G N P rose to 9.1 percent in 1985,
whereas the export share fell to a low for the
period of 5.3 percent, resulting in the record
trade deficit.
Substantial geographic shifts in patterns of U.S.
trade have accompanied the sharp rise in imports
(Chart 2). The Asian share of U.S. trade has grown
from one-fifth to nearly one-third, whereas the oil
exporters' share has fallen from 14.2 percent to
5.8 percent of U.S. trade between 1975 and
1985.2 The share of U.S. trade accounted for by
Latin America and by the Soviet bloc (Soviet
Union and East European countries) declined
significantly since 1975, as well. The shares with
Canada, Europe, and Australia during the same
ten-year period remained roughly constant.

Asia: A Rising Force in U.S. Trade
Trade with Asia (includingthe developing nations and Japan) as a percent of total U.S. trade
rose moderately from 20.9 percent in 1975 to 24.2
percent in 1980. The Asian share then exploded

to reach 32.2 percent of U.S. trade by 1985. In
nominal dollar terms, trade with Asia has quadrupled from $44.7 billion in 1975 to $185.2 billion
in 1985 (Table 1). The majority of this growth can
be traced to rapid escalation of U.S. imports from
Asia, and not to export growth. Imports from Asia

1985, or 55 percent of our total deficit. The U.S.
deficit with Asia was only $3.5 billion in 1975.

The ratio of U.S. exports to Asia relative to U.S.
imports from Asia (X/M, where X/M equal to one
indicates trade balance and less than one indicates a U.S. deficit) further emphasizes the deteriorating trade balance with Asia: it was about
6/7 in 1974-75 but fell to under two-fifths by
1985.3 If ships all carried equal nominal dollar
values of goods, then for every five full ships now
comingto the United States with goods from Asia,
three would return empty.
Over the past decade, U.S. trade with Japan has
consistently accounted for approximately half of
all U.S.-Asian trade. The remaining half is split
among the developing countries of Asia, especially Taiwan, Hong Kong, South Korea, China,
and Singapore. Japan is the second leading U.S.
trade partner (Canada is first), with $95 billion in
total trade in 1985. At $72.4 billion, U.S. imports
constituted over three-fourths of this total.
Since 1975, however, Japan's share of U.S. imports rose sharply to 20 percent from 11.7 percent
as the dollar value of imports grew at an annual
rate of 19.4 percent (Chart 3). Over the same
period Japan's share of total U.S. exports also
increased moderately. The dollar value of exports
to Japan grew at a more modest 9 percent annual
rate.
Rapid growth of trade with Japan compares
with world averages for the United States of 13.1
percent for imports and 7.1 percent for exports.
The developing countries in Asia make up the
remaining half of U.S.-Asian trade. U.S. trade performance is better with this group than with Japan,
but here too the situation has become quite unbalanced. Over the past decade, U.S. imports
from the Asian developing countries have been
growing almost as rapidly as imports from Japan,
at a compounded average annual rate of 18 percent. These developing countries have been
somewhat more accepting of U.S. exports than
Japan. U.S. exports to developing Asian countries
have grown at a compounded annual rate of 10.2
percent over the past decade, in comparison to
Japan's record of 9 percent average annual growth
(Chart 4).
The rapid growth in U.S. imports relative to
exports within this group means that the X/M ratio
has declined by half, from well over nine-tenths
to under one-half, since 1975. In 1985, our $90.2
billion in total trade with this area resulted in a
deficit of $32.2 billion. This exceeds our deficit
with all of Europe but is only two-thirds of our
deficit with Japan.

Clearly, developing Asia has come to claim a
significant sector of U.S. trade. In 1975, trade with
developing Asian countries amounted to 10.7
percent of total U.S. trade; as of 1985, that portion
had grown to 15.7 percent. Breaking down total
trade into its export and import components, the
results parallel the Japanese experience in which
imports have grown much more than exports. The
share of developing Asian countries in total U.S.
imports expanded more than 50 percent, from an
11.1 percent share in 1975 to 16.9 percent in
1985. Similar comparisons for U.S. exports show a
3.4 percentage point increase, from 10.2 percent
in 1975 to 13.6 percent in 1985.

Europe: Share Remains Nearly
One-Quarter, But the U.S. Balance
Declines
Europe has maintained a fairly stable position in
the composition of total U.S. world trade. Over
the ten years from 1975 to 1985, the percent of
total U.S. trade with Europe has varied little, ranging from 21.9 percent to 23.7 percent. Europe's
contribution to total U.S. trade in 1985 compared
with 1975 shows an even smaller change, from
23.3 percent in 1975 to 23.6 percent. The exportimport mix of European trade, however, has
FEDERAL RESERVE BANK OF ATLANTA




changed dramatically. The United States experienced a trade surplus with Europe from 1974 to
1982, reaching a peak surplus of $16.7 billion in
1980, but faced a growing trade deficit of $28.3
billion dollars in 1985. During the course of five
years, then, the U.S. trade balance with Europe in
essence deteriorated by a huge $45 billion. The
ratio of U.S. exports to Europe relative to U.S.
imports from Europe further emphasizes the
degenerating trade balance with Europe: X / M
equaled 4 to 3 from 1975 to 1976, but ten years
later it was halved to 2 to 3.
Over the ten-year study period, U.S. imports
from Europe have grown at a compounded rate of
14.3 percent per annum, whereas U.S. exports to
Europe have grown at only 6.6 percent per annum.

Canada: Stable Overall Share
W i t h Rising Imports
Canada is the United States' most active trading
partner, accounting for 20.3 percent of this country's total world trade, with a dollar value of nearly
$120 billion. During the mid- to late-1970s Canada claimed 20 to 21 percent of U.S. total trade;
however, Canada's share of U.S. trade declined
from 20.9 percent in 1975 to 16.2 percent in 1980
before recovering to 20.3 percent in 1984 and
39

Chart

1985. Canada's continuing importance as a major
trade partner for the United States calls for special
attention to growing deficits with Canada. In 1975
the United States had a relatively small trade
deficit of $1.01 billion with Canada. By 1985 the
deficit amounted to $22.2 billion, and it is still
growing. The X/M ratio, another indicator of
trade patterns, also reflects the size of the deficits;
the nearly balanced ratio in 1975 had fallen to just
more than two-thirds by 1985. Imports from
Canada over the 1975 to 1985 period have grown
at 11.8 percent per annum, compared to export
growth of 8.1 percent yearly. Closer analysis of
U.S. deficits with Canada provides additional insight into the present situation. I n 1982, the deficit
with Canada as a percent of the total U.S. deficit
peaked at 30.7 percent before declining to 14.9
percent in 1985. Nevertheless, over the same
period the dollar value of our deficits with our
largest trading partner has continued to grow.

Latin American trade demonstrates that economic conditions abroad can have a significant
impact on U.S. trade patterns. In 1981 the U.S. ran
a trade surplus of $1.3 billion with Latin America. 4
Yet in 1982, the United States suddenly faced a
deficit totaling $6 billion when austerity measures required Latin America to slash imports to
service its foreign debt. Continued cutbacks were
accompanied by a jump in the U.S. trade deficit
with Latin America to $17.9 billion in 1983 and
$20.4 billion in 1984, before it began to "level off"
to $18.1 billion in 1985.5 As a result, U.S. imports
from Latin America have grown at 11 percent
yearly overthe ten-year period (1975 to 1985), but
U.S. exports to Latin America have remained at
low levels with a mere 6.1 percent per annum
growth rate.

The key trend established with Latin America is
clearly our export share decline (Chart 4). U.S.
exports to this region rose from $17 billion in 1975
to $42 billion in 1981, then plummetted to a low
of less than $26 billion in 1983, recovering to just
$31 billion in 1985. Latin America absorbed about
16 percent of U.S. exports in 1974-75, and as
much as 18 percent in 1981. This share is now 14.6
percent. Growth of U.S. imports from Latin America has also been slow, especially relative to
growth of imports from Asia. Latin America now
OCTOBER 1986, ECONOMIC REVIEW

accounts for 13.6 percent of total U.S. imports versus 16.3 in 1975. Falling export and import shares
have resulted in a decline in total U.S. trade with
Latin America from 16 percent in 1975 to 14 percent in 1985.

Oil Exporters: Boom and Bust
U.S. imports from predominant oil exporters
(the IMF defines these countries as O P E C minus
Ecuador and Gabon, but with O m a n added)
peaked at $57.1 billion in 1980, then receded to
$21.6 billion in 1985, nearing its level of $19.9
billion a decade before. Products imported from
the oil exporting group, as a percentage of U.S.
imports, showed a slight increase in the mid- to
late-seventies from 18.8 percent in 1975 to 22.2
percent in 1980. However, a steady and pronounced decline since 1980 reduced their percentage share to a mere 6 percent in 1985.6
U.S. exports to the oil-exporting countries as a
share of total U.S. exports have followed the general pattern of U.S. imports from these countries,
but with a slightly lagged relationship and less
variation. In 1975, U.S. exports to oil exporters
accounted for 9.6 percent of total U.S. exports.
This figure climbed to 11.1 percent in 1977-78,
slid to 7.7 percent in 1980, and rebounded to 10.4
percent in 1982 before dropping steadily.
The ten-year growth rates of U.S. trade with the
oil exporters is the exception to the general trend
of moderate U.S. export growth and rapid growth
of imports. Over the past decade, U.S. exports to
the oil exporters have expanded at a rate of only
1.4 percent, while U.S. imports from them have
increased on average at an even more meager 0.8
percent rate.
In 1980 the U.S. trade balance with all regions
except this oil exporter group measured a surplus
of $4.0 billion, but this surplus was swamped by
the $40.2 billion deficit with the oil exporters.
From 1982 onwards the trade deficit with oil exporters has diminished, nearly returning to its
1975 level of $9.5 billion. The ratio of U.S. exports
to imports from oil exporters has risen from threetenths in 1980 to nearly three-fifths in 1985.

Asian countries have assumed a large and growing
role in U.S. trade, particularly in the U.S. import
market. Developing nations as well as Japan have
contributed to the increase. The share of our imports supplied by Asia alone is nearing two-fifths,
while our ratio of export to import trade with this
region has declined below two-fifths. Explosive
import growth combined with moderate export
growth to Asia results in the expanding U.S. trade
deficit with Asia, which has climbed to over $80
billion—more than half of our total deficit.

with these countries climbed to a peak in 1979 of
$5.1 billion in exports and $1.5 billion in imports.
The grain embargo imposed by former President
Jimmy Carter caused U.S. exports to these countries to tumble more than $2 billion by 1980
(Table 1 ). U.S. exports have yet to regain their preembargo levels. U.S. exports to Eastern Bloc countries accounted for just 2.4 percent of U.S. exports
in 1975, but the export share rose to 2.8 percent in
1979. In 1985, longafterthe grain embargo's initial
effect, U.S. exports to the Soviet Union and Eastern Europe as a share of total U.S. exports remained a mere 1.4 percent.

The Asian gain in U.S. trade share has not
penalized our two other main trading partners,
Canada and Western Europe. These two areas
roughly maintain their respective shares of just
over one-fifth and just under one-quarter of the
U.S. market. The significant loss of share has been
incurred by oil exporters (primarily in the Middle
East), who saw their share of U.S. trade fall by over
two-thirds from 1977 to 1985. Latin America and
the Soviet bloc also lost U.S. trade share, but the
absolute magnitude of decline was relatively
small.

U.S. imports from the Soviet bloc as a share of
total U.S. imports have always been negligible,
less than one percent of total imports. Following
the same trend as export share, the Soviet bloc
import share peaked in 1979, then dropped so
sharply that from 1982 through 1985 it averaged
less than half of its 1977-79 average.

Conclusion
The composition of U.S. trade by world region
has shifted substantially during the last decade.

NOTES

1

Capital markets worldwide and the international trade sectors of many
other nations show significantly greater evidence of international integration than the U.S. trade sector. For a report on the trade sectors of
other countries see Christopher Paul Beshouri, "The Global Economy:
A Closer Look," Federal Reserve Bank of Atlanta, Economic Review,
vol. 70 (August 1985), pp. 49-51.

2These figures are calculated using the IMF's Direction of Trade Statistics. The IMF classification includes essentially the 13 members of
O P E C ; however, Ecuador and Gabon are excluded, while Oman is
added for a total of 12 oil exporting countries.
3 The

X/M ratios used throughout this article to evaluate the status of U.S.
trade with different geographic regions are not meant to imply that
bilateral trade balance is desirable. Clearly, it is a country's total trade
balance that is ultimately important. However, these ratios help demonstrate changing patterns of U.S. trade from a disaggregated, geographical perspective. As such they can help identify the main source of
our current deficit and thereby guide the analysis of policy options.

4 Latin

America is broadly defined here as all western hemisphere
developing nations. This includes Caribbean as well as Central and
South American nations.

5 The

deficit with Latin America reached one-fourth of the total U.S. trade
deficit in 1983, but by 1985 this share had fallen to one-eighth of the U.S.
deficit. The trade deficit with Latin America has held steady in contrast to
other regions where it has increased dramatically.

6 These

percentages, like those throughout this article, are based on
nominal rather than real changes. In the present case of U.S. imports
from oil-exporting countries, much of the nominal change reflects fluctuations in oil prices rather than volume changes. While it is useful for
some purposes to look at real changes, the present, simpler approach is
appropriate in light of the large size of the U.S. trade deficit measured in
nominal terms.

Notes: All deposit data are extracted fron the Federal Reserve Report of Transaction Accounts, other Deposits and Vault Cash (FR2900),
and are reported for the average of the week ending the 1st Monday of the month. This data, reported by institutions with over $26.8 million
in deposits and $2.6 million of reserve requirements as of June 1986, represents 95fc of deposits in the six state area. The annual rate of
change is based on mast recent data over comparable year ago data. The major differences between this report and the "call report"
are size, the treatrrent of interbank deposits, and the treatment of float. The data generated frcrn the Report of Transaction Accounts
is for banks over $26.8 million in deposits as of June 1986. The total deposit data generated frcm the Report of Transaction Accounts
eliminates interbank deposits by reporting the net of deposits "due to" and "due from" other depository institutions. The Report of
Transaction Accounts subtracts cash in process of collection frcm demand deposits, while the call report does not. The Southeast data
represent the total of the six states. Subcategories were chosen on a selective basis and do not add to total.
* = fewer than four institutions reporting.
N.A. = Not available at this time. Series being revised to reflect reporting changes.
