WEEKLY LETTER

July 27, 1990

Interest Rate Competition
Since late 1982, commercial banks and thrifts
have offered the money market deposit account
(MMDA), a savings account with features similar
to and competitive with those of money market
mutual funds. Until 1987, banks and thrifts
offered rates on MMDAs that were closely tied
to the rates on money market funds. Since then,
however, MMDA rates have become less sensitive
to money fund rates. In this Letter, we study this
change in MMDA pricing, and find that changes
in the structure of banking markets caused by
changes in the intensity of thrift competition
may be partly responsible.

The MMDA market is born
Money market deposit accounts were authorized
for banks and thrifts in December 1982 as a
combination savingsliimited transaction account
that would make them competitive with money
market mutual funds. Today, banks and thrifts in
the U.S. hold nearly $490 billion in MMDAs,
versus about $430 billion in money funds.

in the money fund rate in a rising rate environment is confirmed by research at the Federal
Reserve Bank of San Francisco. When interest
rates have risen, banks and thrifts have been able
to limit the rise in their MMDA rates without too
much risk of losing deposits. Instead, they have
tended to raise interest rates on certificates of
deposit (CDs). Changes in CD rates affect only
new accounts, and are therefore less costly than
are changes in the MMDA rate, which would
apply to both new and old accounts.

Money market funds pay a rate that is determined by the yields on the money market assets
(such as Treasury securities, commercial paper,
and large bank CDs) they hold. In contrast,
depository institutions establish their own rates
on MMDAs. Through the mid-1980s, the rates on
money market funds and MMDAs were tightly
linked, with MMDA rates only slightly below
those on money funds (see chart). Data from the
Bank Rate Monitor indicate that bank and thrift
MMDA rates averaged 94 percent of the national
average money market fund rate from 1984 to
1986. Moreover, changes in these two rates were
highly correlated, with MMDA rates moving an
average of 60 basis points for every 100 basis
point change in money fund rates.

Looser link
According to the chart, the close relationship
between money market fund and MMDA rates
appears to have broken down after 1986. The
average differential between rates paid on money
market funds and MMDAs has widened significantly. Whereas MMDA rates in the 1984-86
period were five to ten percent below the money
fund rate, after 1986 they have been more than
20 percent below the money fund rate on average. The average difference between MMDA
rates and the money market fund rate climbed
from under 100 basis points from 1984 to 1986
to over 200 basis points after 1986.

Western Banking is a quarterly review of banking
developments in the Twelfth Federal Reserve District. It is published in the Weekly Letter on the fourth
Friday of January, April, July, and October.

FRBSF
In the current period, changes in MMDA rates
also respond less to changes in money fund
rates. For every 100 basis point change in the
average money market fund rate since early 1987,
MMDA rates have moved on average on Iy 20
basis points. This is one-third of the response
of MMDA rates in the prior period.

Interest sensitivity of MMDAs
The apparent uncoupling of MMDA and money
market fund rates may have occurred for a number of reasons. First, it may be a response to the
rise in the money fund rate that occurred during
most of the later period. As noted above, MMDA
rates have tended to be less responsive to money
fund rates when rates have been rising than
when they have been falling. Thus, it should not
be a surprise that money fund and MMDA rates
would appear to have become uncoupled as
interest rates rose after 1986.
However, a rising money fund rate cannot fully
explain the apparent uncoupling of rates in the
current period. The spread between the two rates
is too large to be consistent with the earlier
period. Moreover, as money fund rates have
fallen over the past year, MMDA rates have not
been as responsive to this decline as they were
previously. Money fund rates have fallen about
160 basis points since early 1989, but MMDA
rates have fallen only 40 basis points or so; this
is roughly the same average response that we
observe during the post-1986 period as a whole.

The thrift crisis
Thus, a structural shift in the market for MMDAs
appears to have occurred around 1987. This shift
has altered the relationship between rates on
MMDAs and those on money funds. It is difficult
to identify a unique cause for this. Nevertheless,
the uncoupling of MMDA rates from money fund
rates coincides with the deterioration in the financial condition of FSLlC-insured thrift institutions.
Such a deterioration in financial condition may
have limited thrift competition in the MMDA
market, and diminished banks' incentives to
compete aggressively as well.
As early as the second half of 1985, the S&L
industry began reporting net outflows of new
retail savings deposits. Earnings deteriorated dramatically thereafter, with the industry as a whole

reporting virtually zero earnings in 1986 and
progressively larger multi-billion dollar losses in
subsequent years. The industry's return on assets
(ROA) followed a similar pattern of deterioration.
Another sign of the deteriorating health of the
industry has been the declining number of insured thrifts. A small drop in 1986 was followed
by much larger declines in subsequent years.
With the funding to close insolvent thrifts that
was provided by the passage of the Financial
Institutions Reform, Recovery and Enforcement
Act (FIRREA) in August 1989, the number of
thrift institutions has declined even further.
As the financial prospects and performance
of thrifts have deteriorated, the industry has attempted to minimize its cost of funds, bolster
earnings, and raise capital. As a result of these
efforts, the ability of thrifts to compete in the
MMDA market may have declined. FIRREA also
has limited the ability of ailing thrifts to offer
above-market deposit rates.
Consequently, the premium thrifts have been
paying over bank MMDA rates has declined in
recent years. The behavior of MMDA rates at a
group of large California S&Ls is especially striking. As shown in the chart, these S&Ls have paid
an almost constant rate on MMDAs since 1986,
despite strong movements in money fund rates.
In contrast, MMDA rates at large California banks
are now higher than rates at large California S&Ls
for the first time in years.

Impact on depositors
Competition for depositors' funds can take
many forms. In California, for example, banks
have escalated efforts to provide "better" banking services, such as 24-hour telephone service,
longer branch hours, and Saturday banking.
Nevertheless, developments in the thrift industry
appear to have diminished competition in the
market for MMDAs and contributed to an uncoupling of MMDA and money market fund
rates. Thus, it is not surprising that MMDA
balances have fallen $24 billion nationwide
since 1987 while higher yielding money market
funds have gained $116 billion.
