Wh y Redefinethe M's?
Everyone is becoming more sophisticated about money and finding new
ways to economize on checkingaccount balances. Many of the recent
regulatory changes and financial innovations permit individuals, as well as
businesses and governmental units, to
improve cash-management practices.
Butthe very effectiveness of these innovations is causing problems for the
Federal Reserve, as it attempts to use
money-supply measures in achieving
its monetary-policy goals.
Deposit shifts are occurring among the
demand, savings and time components
that make up the monetary aggregates
(M 1, M 2, M 3, et al.), and shifts are also
occurring among depository institutions, and between deposits and nondeposit substitutes. These
alter
the previously observed relationships
of the money aggregates with GNP,
income, and interest rates, and thus
make aggregate behavior difficult to
interpret. To reflectthe impact of recent
financial innovations, the Federal Reserve Board of Governors presented a
proposal in the January Federal Reserve
Bulletinfor redefining the "M's" by
"grouping together similar kinds of
deposits at all depository institutions."

Changesin demandbalances
Many of the recent innovations and
regulatory changes have limited the
growth of demand deposits at commercial banks. At the same time, they
have caused shifts to new-type transaction balances tied to interestbearing accounts - such as negotiable orders of withdrawal, automatic
transfers from savings, and credit
union share drafts - at all types of
depository institutions. The impact of

these innovations has varied widely
among the major sectoral holders of
demand balances, causing significant
changes in the composition of demand
deposits, the major component of M1.
For some sectors, substantial economies in demand balances have already
taken place; for others, the process is
far from complete or just getting
underway, and these shifts will further
alter the behavior of M 1.
The nonfinancial business sector,
which accounts for about 40 percent
of total demand deposits, for years has
economized considerably on its
demand-balance holdings. By utilizing a wide-range of short-term options
for investment of balances in excess of
immediate needs, large corporations
are approaching the potential minimum in their holdings of transaction
balances. In addition, their "required"
demand balances are declining as
banks, in response to competitive
pressures for corporate loans, substitute fees in lieu of requiring "compensating" demand balances on loan
extensions.
Medium- and small-sized business
firms have not matched, in relative
terms, the demand-depositeconomies
achieved by large corporations,
mainly because size constraints limit
their access to the wide range of shortterm investment options available
to larger firms. However, they have
been able to improve their cashmanagement practices by shifting
funds from demand balances to savings accounts, as a result of a
November 1975 regulatory change
that permits businesses to hold up to
$150,000 in savings deposits.
(continued on page 2)

A similar cash-management tool
became available to local governmental units in November 1974
through a regulatory change that
permits domestic governmental units
to hold savi ngs deposits. At the state
level, the spread of sophisticated cashmanagement techniques, utilizing
pooled-investment accounts, has significantly constrained the growth of
public demand deposits. For both state
and local governments, further declines in demand-deposit use can be
expected because of legislative and
regulatory trends liberalizing investment alternatives for governmental
units, and because of the spread of the
pooled-investment concept to local
units as well as to more and more
states.

Shift in consumerdeposits
Recent regulatory changes have had
their most dramatic impact on the consumer sector, which accounts for
about one-fourth of total demand
deposits. In its money-supply redefinition proposal, the Federal Reserve
listed a number of changes that have
enhanced the ability of individuals to
economize on demand balances either directly through issuance of
negotiable instruments drawn on
interest-bearing accounts or indirectly
by automatic withdrawals from savings to checking accounts, or by preauthorized telephone and point-ofsale transfers from savings accounts.
The greatest impact came last fall from
the authorization of automatic transfers from bank savings accounts and
the extension of N OW authority to
depository institutions in New York

2

State. Mutual money-market funds,
which provide limited withdrawal
privileges in negotiable form, also
have been attracting significant
amounts of consumer funds.
The extent to which consumers use the
new transaction-type accounts N OW's, CU share drafts, and ATS
accounts - depends on their effective
cost compared with the cost of regular
checking accounts. When minimumbalance requirements are met, most
such accounts impose no transaction
or fee charges on withdrawals. Consumers using these new interestbearing transaction accounts can
effectively reduce their demanddeposit holdings to a "zero" amount.
This projected economizing of consumer demand deposits will significantly affect the elasticity of current
M,'s response to income growth.

Savingsand time shifts
Financial innovations have also affected the savings and time-deposit components of currenfM 2 and M 3 , the
broadly defined money measures. The
new transaction accounts (ATS,
N OW's and CU's) are drawing funds
from regular savings accounts at both
banks and thrifts, as well as from demand deposits. Households also have
shifted massive amounts of funds from
savings into the more attractively
priced "money-market certificates"
(M MC's) which have been available
since mid-1 978 at banks and savings
and loan associations. (These f1oatingrate 6-month time certificates, in minimum denominations of $10,000, are
tied to the 26-week bill auction rate).
Since thrift institutions could offer
M M C's at a favorable rate differential
prior to last month, substantial
amounts of funds also shifted from
banks to thrifts. If the concept of applyi ng money-market rates spreads to

smaller-denomination time certificates, the shift out of the savings
component into time deposits will
accelerate further.
The heavy issuance of M M C's is
further altering the liquidity of the
time-deposit component of the money
supply by concentrating funds in
6-month maturities. This component
had become significantly less liquid as
a resuIt of the lengthen i ng of matu rities
at both banks and thrifts following the
1973 and 1 974 increases in regulatory
rate ceil ings on longer-term certificates. But market-rate certificates
affect the broadly defined monetary
aggregates most significantly in
another way, by making consumer
time deposits less subject to disintermediation when interest rates rise.

ProposedM's
The new Ml aggregate, as proposed by
the Board, would include the current
components - currency and demand
deposits - plus all other transactiontype accounts at banks and thrift institutions (less deposits of foreign commercial banks and official institutions).
Inclusion of all these accounts would
eliminate the effects of the shifts from
consumer demand deposits to the new
interest-bearing transaction accounts.
But since these accounts consist of
savings-type funds as well as those
needed for transaction purposes, the
proposed Ml would be greater than
the current M 1. If the proportion of
these highly interest-sensitive savings
balances becomes significant, the
demand elasticities of the proposed
Ml with respect to interest rates will
tend to differ from those of the current
Ml measures.
The proposed M2 aggregate wou Id
include the components of the new Ml
aggregate plusregu lar savings deposits
3

(i.e., savings deposits as currently defined less transaction-type accounts) at
both banks and thrift institutions. The
addition of "regular" savings deposits
would "wash out" the effects of shifts
from regu Iar savings accou nts to transaction-type balance accounts. It
would also cancel out the effect of
fund transfers between banks and thrift
institutions for all the deposit components included in M 2.
The proposed M3 would add to the
new M2 aggregate the time deposits of
all maturities and denominations at
both banks' and thrift institutions. It
would include large-denomination'
($1 00 ,000 and over) negotiable CO's,
which currently areexcluded from
both M2 and M 3 . Since this broader
proposed aggregate would include all
types of accounts - demand, transaction-type, savings and time - at all
depository institutions, its movements
would not be affected by the shifts
occurring among deposit categories or
among institutions.
' The public's monetary-asset holdings
are becoming increasingly fluid, atleast partly because of the continued
rapid pace of regulatory and financial
innovations. No one aggregateor
group of aggregateswill be optimal for
all purposes. In recognition of this fact,
the Board proposes to publish separately the "building block" components of the aggregates,so thatfinancial
analysts will be able to monitor the
impact of financial changes in more
detail.
