Decomposing the Aggregates
In recent years, even without major definitional changes, market forces have dramatically altered the composition of financial
assets included in the narrow (M-l) and
broader (M-2) monetary aggregates.The widespread consumer acceptance of interestbearing checking accounts-N OW accounts,
automatic transfer (ATS)accounts, and share
drafts -has led to strong growth in "other
checkable deposits," and accounted for
nearly all the growth in M-1. Similarly, the
popularity of money market funds and market-return small-denomination time deposits
has accounted for all of the strength in the
broader M-2 aggregate. Indeed, the strength
in these various components has profoundly
affected the traditional separation of deposittype money balances into the two basic
aggregates -one (M-l) composed of transaction balances, and the other (M-2) composed
of both savings and transaction balances.
Throughout most of the recent period of record high inflation rates and interest rates,
market forces have spurred a flight from the
traditional "core" deposits-checking, passbook savings, and fixed-rate time certificates.
Record interest rates have led consumers to
press for market-return financial instruments;
financial institutions have responded byoffering new types of financial assets,i.e.,
money-market fund shares provided by the
securities industry, and retail repurchase
agreements and deposit-sweep accounts provided by depository institutions. In addition,
to permit depository institutions to compete,
the regulatory authorities have authorized
them to offer a myriad of new deposit instruments. However, these new instruments tend
to have either transaction or savings characteristics, but not both.
The intense market forces described here
have determined the growth of the major M-l
and M-2 components over the last several
years. Lower interest rates at times have
caused reverse flows back into the traditional

core deposits, but these flows have been
swamped by the pervasive switch into a variety of new accounts, some of them developi ng in response to the gradual deregu lation of
interest-rate ceiJings. These include fixedinterest paying transaction balances (N OW
accounts and ATS accounts), market-retum
investment balances (6-month money market
certificates, 30-month smalI savers certificates, and tax-free 12-month all savers certificates), as well as instruments that exhibit
both payments and savings characteristics
(money-market funds, deposit-sweeps, and
retail repurchase agreements).

Other checkabledeposits
Since the last (1980) revision of the monetary
aggregates, "other checkable deposits" have
been included as a component of the narrow
M-l aggregate, in addition to the traditional
currency and demand deposits. This category
now includes a variety of interest-earning
transaction accounts: automatic transfer service (ATS) accounts that link checking and
savings balances to provide both transaction
services and a positive return (presently 5.25
percent); negotiable orders of withdrawal
(N OW), which are basically checking accounts paying 5.25 percent interest; share
drafts, which are interest-bearing checking
accounts offered by credit unions; and demand deposits at thrifts.
"Other checkable deposits" have risen
sharply since December "1980,when banks
and thrifts became able to offer N OW accounts nationwide. Indeed, other checkables
showed the only strength among M-l components during this period. They rose by
$60.4 billion from year-end 1 980to mid-year
1982, whereas the total M-1 increase was
only $36.5 billion over this same period (see
Chart 1). These figures reflected some switching by consumers from non-interest-bearing
demand deposits to N OWand ATSaccounts,
as well as a slightdecline in business demand
balances and a strong increase in currency.

Some proportion of the funds in N OW accounts also carne from savings balances.
Accordingly, households' $87 billion in interest-bearing transaction accounts this June
apparently exceeded their holdings in noninterest-bearing checking accounts.

savings balances. In the fourth quarter of
1981 and first quarter of 1982, householdchecking and passbook-savings balances
showed renewed strength along with other
checkable deposits. (A similar pattern appeared du ri ng the summer of 1980, when
interest rates bottomed out following the
spring peak in rates.) But at the same time,
growth rates dec Ii ned for the market -retu rn
components of M-2-small-denomination
ti me deposits and money-market fu nd shares.

Market return
Similarly, M-2 components that pay market
returns have accounted for all of the growth
in the broader aggregate over the past fou r
years. These have included, in particular,
small-denomination time deposits and general-purpose money-market mutual funds
transferred from other M-2 componentspassbook savings deposits and fixed-rate time
certificates. From the introduction of moneymarket certificates in June 1 978 until mid1982, market-return small-denomination
time deposits plus money-market funds rose
from virtually zero to about $940 billion, or
roughly one-half of the M-2 aggregate.

Some of the reverse shifts of funds into core
deposits have affected the growth of the aggregates in offsetting ways. In particular, the
temporarily altered growth pattern of M-2
components has scarcely affected the M-2
growth rate, since a major portion of the shift
represents growth in the other-checkables or
passbook-savings components of M-2 at the
expense of the small-denomination time deposit or money-market fund components.
The effect of these shifts on M-2 should net
out, but a different pattern may be evident for
the M-1 aggregate. A shift from M-2 balances
into demand deposits or other checkables,
such as we witnessed in late 1981 and early
1 982, thus would tend to boost the M-1
growth rate.

Market-return consumer time deposits and
money-market fund shares may continue
to show much more rapid growth than the
remaining below-market-return consumer
deposits included in M-2. By 1986, interestrate ceilings on time and savings deposits are
schedu led to be phased out under the Depository Institutions Deregu lation and Monetary
Control Act of 1980. Ultimately, then, all
consumer time and savings deposits should
bear a market return. In the interim before
complete deregulation, however, market
forces may lead consumers to continue transfering investable funds from controlled-return
instruments to those offering market-determined rates.

What next?
How has this revolution in the handling of
household money balances affected various
market participants? Certainly from the
saver's vantage point, interest-bearing checking and market-return savings instruments
provide both a wider array of investment options and more income than deposit balances
would have provided in an era of belowmarket interest-rate ceilings. Financial institutions meanwhile find these new accounts
are much more expensive than the traditional
checking, savings and fixed-rate consumer
time certificates. Moreover, in a high interestrate environment, the trend toward more expensive funding certainly will continue as
financial institutions continue to innovate
around interest rate restrictions, and as
the Depository Institutions Deregulation
Committee proceeds with the gradual phase-

Exceptions
The runoff in core deposits might possibly be
slowed (or even reversed) if interest rates
dropped substantially. (For that matter, investors might be willing to settle for a lower
return in today's uncertain economy because
of increased liquidity preference.) The general reduction in interest rates from their mid1981 peak reduced the opportunity cost of
holding traditional transaction or passbook2

out of interest-rate ceilings mandated by
the Monetary Control Act.

market rates that attract both types of balances. Consumers will have little incentive
to separate their funds into the traditional
checki ng and investment accou nts if they can
earn a high yield on an account that offers
both services. Thus, we may no longer be
able to define money along the familiar lines
of M-1 . But, we may still be ableto define M-2
in the present manner, even while market
forces reshape the aggregates-with more
M-l balances taking on the market-return
characteristics of present M-2 balances and
with more M-2 balances providing the payments services now associated with M-l
balances. However, the dramatic change in
the nature of M-2 may create additional uncertainties in an environment of deregulation.

Ultimately/with the further blending of consumer transaction and investment balances,
the distinctions now used in defining M-l and
M-2 may become further blurred. There will
always remain some distinction, of course.
Transaction accounts will always pay a lower
return, because of their higher reserve requirements and higher costs of servicing,
compared to investment-type accounts.
With complete deregulation, households
shou Id have a wider array of transaction and
investment services to choose from. Also, as
with the current money-market funds prototype, many institutions may offer accounts
providing both the checking services and the
