The Transmission of Exchange Rate Changes to Output and Inflation

Remarks by
Stanley Fischer
Vice Chairman
Board of Governors of the Federal Reserve System
at
“Monetary Policy Implementation and Transmission in the Post-Crisis Period,”
a conference sponsored by the
Board of Governors of the Federal Reserve System
Washington, D.C.

November 12, 2015

Good evening. My discussion tonight will focus on a key transmission channel in
an open economy--the exchange rate. 1 The exchange rate is a primary focus of central
bankers in small open economies as well as a prime concern of the broader public in
those economies--and, to a lesser extent, in even the largest of economies. When I was
governor of the Bank of Israel prior to joining the Federal Reserve, my markets screen
was continuously open at a chart of the exchange rate of the shekel against the dollar.
For small open economies, the exchange rate may well matter as much for output and
inflation as do interest rates. 2
Given that the U.S. economy is much less open than Israel’s, it is not surprising
that fluctuations in the dollar typically receive somewhat less attention here in the United
States. Indeed, much of the focus on dollar fluctuations in the recent research literature is
on transmission to foreign economies, including through balance sheet channels, as in the
Bank for International Settlements paper (Hofmann, Shim, and Shin, forthcoming) that
will be presented tomorrow. Nevertheless, the exchange value of the dollar also plays a
significant role in the U.S. economy, a role that has increased over time given growing
global trade and financial linkages. My remarks will focus on the consequences of the
dollar’s ascent since last summer for U.S. output and inflation--and thus for monetary
policy.

The views expressed here are my own and not necessarily those of others at the Board, on the Federal
Open Market Committee, or in the Federal Reserve System. I am grateful to Christopher Erceg, Joseph
Gruber, and Deborah Lindner for their contributions to this speech and to William English and David
Skidmore for comments.

At times, starting in the 1990s, several central banks--most prominently, the Bank of Canada--have used a
monetary conditions index, generally a weighted average of changes in a short-term interest rate and a
multilateral exchange rate from some baseline, as a policy indicator.

-2 Size of Dollar’s Appreciation and Its Causes
As seen in figure 1, the roughly 15 percent appreciation of the broad real dollar
since July 2014 is large, though not unprecedented by historical standards. 3 Two related
factors appear to have played key roles in the dollar’s rise. First, while the U.S. economy
has performed relatively well--as is visible especially in our steady progress toward full
employment--major foreign economies have generally experienced weak growth, along
with persistently low inflation. Because foreign central banks responded appropriately by
providing additional monetary accommodation, foreign interest rates have declined
relative to U.S. interest rates, encouraging investors to shift into dollar-denominated
assets and in turn boosting the dollar. But widening interest rate differentials can explain
only part of the dollar’s large ascent. A second factor has been heightened concern about
the global outlook and an associated decrease in investor risk tolerance--factors that tend
to increase investment in dollar assets. In recent months, investors have been particularly
focused on the possibility of a sharp slowdown in China and other emerging market
economies, with commodity exporters seen as particularly vulnerable in the wake of the
dramatic drop in oil and non-oil commodity prices since the summer of 2014.
Effects of a Stronger Dollar on U.S. Activity and Inflation
In considering the transmission of changes in the dollar’s value to U.S. output and
inflation, it will be convenient for illustrative purposes to focus on the effects of a 10
percent appreciation that is assumed to be permanent--and then to draw on this analysis to
provide some guidance on how the dollar’s rise since mid-2014 has played out.

The broad dollar is a weighted average of the foreign exchange value of the U.S. dollar against the
currencies of a broad group of major U.S. trading partners. More information on the construction of the
index can be found in Loretan (2005).

-3 Because the main way in which a stronger dollar affects U.S. output is through
causing real exports to decline, I will begin by focusing on the factors determining the
export response. Broadly speaking, an appreciation of the dollar reduces U.S. exports
because it causes the relative price of U.S. goods to rise in foreign markets; for example,
the price in yen of a U.S.-made pair of jeans will rise. To gauge the quantitative effects
on exports, the thick blue line in figure 2 shows the response of U.S. real exports to a
10 percent dollar appreciation that is derived from a large econometric model of U.S.
trade maintained by the Federal Reserve Board staff. 4 Real exports fall about 3 percent
after a year and more than 7 percent after three years. 5 The gradual response of exports
reflects that it takes some time for households and firms in foreign countries to substitute
away from the now more expensive U.S.-made goods.
A stronger dollar makes foreign goods cheaper for U.S. consumers and hence
boosts U.S. real imports. Nevertheless, an extensive literature has found that the degree
of pass-through of exchange rate changes to U.S. import prices is low, as foreign
exporters prefer to keep the dollar price of the goods they sell in the U.S. market
relatively constant. For example, a typical estimate is that an appreciation of the dollar of
10 percent causes U.S. non-oil import prices to fall only about 3 percent after a year and
only slightly more thereafter. 6 The low exchange rate pass-through helps account for the
more modest estimated response of U.S. real imports to a 10 percent exchange rate

The results presented here are taken from the staff’s U.S. International Transactions (USIT) model of the
U.S. external sector. A forthcoming article in the Federal Reserve Board’s International Finance
Discussion Papers, or IFDP, Notes series will provide further detail on the structure and estimation of the
trade block of the USIT model that is used in these computations.

It may be useful to note that exports in 2014 amounted to about 13-1/2 percent of GDP and imports to
16-1/2 percent of gross domestic product.

These estimates are consistent with recent analysis by Gopinath (2015) and Bussière, Delle Chiaie, and
Peltonen (2014).

-4 appreciation shown by the thin red line in figure 2, which indicates that real imports rise
only about 3-3/4 percent after three years. 7
Figure 3 uses these results to gauge how a 10 percent dollar appreciation would
reduce U.S. gross domestic product (GDP) through the net export channels we have just
discussed. The staff’s model indicates that the direct effects on GDP through net exports
are large, with GDP falling over 1-1/2 percent below baseline after three years.
Moreover, the effects materialize quite gradually, with over half of the adverse effects on
GDP occurring at a horizon of more than a year.
In interpreting these estimated effects on GDP, it is important to underscore that
the estimates do not take account of any offset due to monetary policy easing--a key
consideration that I will discuss shortly. Even so, recalling that the dollar’s actual
appreciation has been about 15 percent, the model estimates suggest that the cumulative
reduction in U.S. aggregate demand from the dollar’s appreciation is likely to total almost
2-1/2 percent of GDP after three years--in the absence of policy action to boost private
demand or government spending. Given these perhaps surprisingly large effects, an
obvious question is, how well has the model done so far in accounting for the actual
behavior of U.S. real net exports? While trade flows are affected by many factors that are
difficult to capture in models--such as the labor disputes at major ports that occurred
earlier this year--the drag from net exports over the past year does appear to be relatively
close to the estimated effect implied by the staff’s econometric trade model, with net

7

In the staff’s trade model, imports are specified to depend on GDP in addition to the exchange rate. The
estimates shown in figure 2 simply show the effects arising through the latter channel. Similarly for
exports, the staff’s model also controls for changes in a trade-weighted aggregate of foreign GDP, with the
estimates in figure 2 showing only the effects from a change in the value of the dollar.

-5 exports reducing GDP by almost 3/4 percentage point in the data, compared with an
estimated fall of 1 percentage point in the model.
Looking forward, given that the effects of the stronger dollar play through
gradually to the economy, there is good reason to expect that the drag on GDP growth
from the stronger dollar will persist well into next year and likely spell continued
weakness in the traded-goods-producing sectors of the economy that are especially
exposed to the exchange rate. Indeed, the more export-oriented manufacturing sector has
already taken a hit during the past year and has experienced weaker growth than the
broader economy.
Turning now to inflation, consumer price inflation has been running well below
the Federal Reserve’s 2 percent target, and the strong dollar has played an appreciable
role in this shortfall. One way in which the stronger dollar depresses inflation is by
putting downward pressure on import prices. Figure 4 uses an econometric model
discussed in a recent speech by Chair Yellen to illustrate how a 10 percent appreciation
of the dollar might play through to core personal consumption expenditures (PCE)
inflation, which excludes the more volatile food and energy components. 8 This particular
model implies that core PCE inflation dips about 0.5 percent in the two quarters
following the appreciation before gradually returning to baseline, which is consistent with
a four-quarter decline in core PCE inflation of about 0.3 percent in the first year
following the shock. While the Board staff uses a range of models to gauge the effect of
shocks, the model employed in figure 4--as well as other models used by staff--suggests
that the dollar’s large appreciation will probably depress core PCE inflation between

-6 1/4 and 1/2 percentage point this year through this import price channel. Thus, given that
core PCE inflation is running around 1-1/4 percent on a four-quarter-change basis, the
stronger dollar has played a material role in holding core PCE inflation below 2 percent.
A second channel through which dollar appreciation reduces inflation is by
increasing economic slack. Greater slack amplifies the downward pressure on inflation,
although the quantitative effect is probably fairly modest given the flat slope of the
Phillips curve. Because the pass-through of dollar appreciation to oil and food
commodity prices is much higher than for most imports, dollar appreciation tends to
depress overall PCE inflation by even more than it depresses core inflation.
An important difference between the transmission of dollar appreciation to
inflation compared with output is that the effects on inflation are probably more transient.
In particular, given that most of the effect on inflation occurs through changes in import
prices--and import prices respond quickly to the exchange rate--the peak effect on
inflation probably occurs within a few quarters. From the standpoint of the outlook, this
transience means that some of the forces holding down inflation in 2015--particularly
those due to a stronger dollar and lower energy prices--will begin to fade next year.
Consequently, overall PCE inflation is likely on this account alone to rebound next year
to around 1½ percent. And as long as inflation expectations remain well anchored, both
core and overall inflation are likely to rise gradually toward 2 percent over the medium
term as the labor market improves further and the transitory effects of declines in energy
and import prices dissipate.

-7 U.S. Monetary Policy and the Dollar
The stronger dollar and some of the factors causing it, including weaker foreign
demand, have played an important role in accounting for revisions to the expected path of
U.S. policy rates compared with what was expected in the summer of last year. The
forecasts made by Federal Open Market Committee (FOMC) participants on a quarterly
basis, which are published in the Summary of Economic Projections (SEP), provide a
good indication of the extent to which forecasts for inflation, output growth, and the
federal funds rate have changed since the summer of 2014. The June 2014 SEP showed
U.S. GDP growth centered at roughly 3 percent in 2015 and core inflation running around
1-3/4 percent, and the median participant projected that the appropriate level of the
federal funds rate at the end of 2015 would be 1-1/4 percent before rising to 2-1/2 percent
at the end of 2016.9 But in the most recent SEP following the September 2015 FOMC
meeting, the median participant saw GDP growth at only 2 percent this year, core
inflation at 1-1/2 percent, and the federal funds rate below 1/2 percent at the end of 2015
before rising to only 1-1/2 percent at the end of 2016.10
This greater degree of monetary accommodation seems appropriate given the
adverse effects on U.S. aggregate demand coming from the rise in the dollar, an
associated weakening of foreign economic prospects, and other developments that have
restrained spending and kept inflation undesirably low. Monetary policy easing helps
through “crowding in” domestic demand, which in turn helps boost price inflation and
makes it less likely that inflation expectations drift below our 2 percent target.

-8 The Board staff’s general-equilibrium models that take explicit account of the
ability of monetary policy to crowd in domestic demand--including the staff’s FRB/US
and multicountry SIGMA models--suggest that monetary policy easing can substantially
mitigate the effects of adverse shocks on GDP, including from the recent run-up in the
dollar. In the case of the dollar shock considered previously, these models suggest that
the all-in effects of the stronger dollar on GDP are only about one-half to two-thirds as
large as implied by the trade model that abstracts from a monetary policy response--still
substantial, to be sure, but much less significant for the economy than if monetary policy
failed to play an active role.
Conclusion
To wrap up, while the dollar’s appreciation and foreign weakness have been a
sizable shock, the U.S. economy appears to be weathering them reasonably well,
notwithstanding their large effects on certain sectors of the economy heavily exposed to
international trade. Monetary policy has played a key role in achieving these outcomes
through deferring liftoff relative to what was expected a little over a year ago. The
October 2015 FOMC statement indicated that it may be appropriate to raise the target
range for the federal funds rate at the next meeting in December, though the outcome will
depend on the Committee’s assessment of the progress--realized and expected--that has
been made toward meeting our goals of maximum employment and price stability. 11 Of
course, as policymakers, we must always be vigilant to events unfolding differently than
we expect, and we must be ready to react accordingly.
