The Federal Reserve and Monetary
Policy
The Federal Reserve regulates banks by requiring them to
hold a certain amount of their assets as either cash or
deposits with the Federal Reserve. Prior to the Depository
Institutions Deregulation and Monetary Control Act (DIDMCA)
passed in 1980, only banks that were members of the Federal
Reserve system had to obey these regulations. National
banks, banks that had received their charter from the
Comptroller of the Currency, which is part of the U.S.
Treasury Department, had to belong to the system. But state
banks, which had obtained their charters from state banking
authorities, did not have to belong, and most did not.
Because the regulations to hold assets that did not earn
interest (prior to October, 2008, the Fed did not pay
interest on bank deposits) were costly for most banks, most
new banks during the 1960s and 1970s were chartered as state
banks, and the percentage of deposits held in member banks
declined during this period. This decline worried government
policy makers and was a major reason for the change in
regulations in DIDMCA. Now all financial institutions that
issue deposits against which checks can be written are
subject to the same reserve requirements.
We saw that banks created money as a by-product of their
quest for profit. Banks are limited in the process of money
creation by the need to hold some assets in the form of
reserves. In the early days of banking, banks needed
reserves so that they could redeem deposits or notes on
demand. Today the amount of reserves and the form that they
take are determined by government regulation. In the United
States only vault cash or deposits held at a Federal Reserve
Bank can serve as reserves. The amount of reserves that
banks must hold is calculated as a percentage of the
deposits they hold. This percentage is called the required
reserve ratio. In equation form, required reserves are
computed as:
(1) Required Reserves = (Required Reserve
Ratio)x(Deposits).
Banks can hold more reserves than are required. Any
reserves above what are required are excess reserves,
or:
(2) Excess Reserves = Legal Reserves - Required
Reserves.
In October of 2008 Congress granted the Federal Reserve
the authority to pay interest on bank reserves, a seemingly
small change that marks a major break in the way the Federal
Reserve conducts monetary policy. To consider what the Fed
is doing now, it is best to
first explain how monetary policy worked before October,
2008.
When reserves earned no interest, banks preferred not to
hold excess reserves because in doing so they sacrifice the
opportunity to hold other assets that earned interest.
Between 1960 and 2008 the amount of excess reserves held in
the banking system was only a small fraction of total
reserves.1
When banks try to minimize excess reserves, any change in
either reserves or in the required reserve ratio will change
the amount of deposits people hold, and thus the amount of
money in circulation. Banks by themselves can change
neither. Although the public can cause changes in both, most
changes in them were the result of the Federal Reserve
System using three policy tools.
The first policy tool, which has not been used as a tool
of monetary policy for decades, is the ability to change
the required reserve ratio. If the Federal Reserve
increases this ratio, the banking system is forced to
destroy money, and if the Federal Reserve decreases this
ratio, the system is encouraged to create
money.2
Although it too has been a minor policy tool in the past
two or three decades, the discount rate is a second
policy tool the Federal Reserve possesses. One way a bank
can obtain reserves is by borrowing them from the Federal
Reserve. When the Federal Reserve charges a high interest
rate for these borrowings, banks will not borrow as much
reserves as when the Federal Reserve charges a low interest
rate.
A third and the only policy tool
of importance before October, 2008 was open-market
operations.3 In open-market operations the
Federal Reserve buys or sells U.S. government securities,
usually T-bills, in the secondary market.4 When
the Federal Reserve buys securities, it creates the funds
with which it buys T-bills. It pays with a check drawn on
itself, and when a commercial bank submits this check for
payment, the bank gets reserves that did not previously
exist.5 The process by which the Federal Reserve
creates bank reserves parallels the process by which banks
create money. A major difference is that the creation of
bank reserve is not a by-product of a quest for profit. On
the contrary, any profit is a by-product of an attempt to
maintain some level of reserves. Indeed, if a modern central
bank set out to maximize profit, it is doubtful that the
monetary system could long survive.
In October 2008 the Fed gained and began to use a fourth policy tool, setting interest rates on reserve deposits that banks hold at the Federal Reserve. This policy tool is discussed in a later section.
Decisions about how these tools will be used are
reached by twelve voting members of the Federal Open
Market Committee (the FOMC). The FOMC meets each month
and determines what the monetary policy of the United States
will be. This control over monetary policy means that the
twelve people who vote on this committee are among the most
powerful people in Washington. Seven of these twelve make up
the Board of Governors of the Federal Reserve System. The
governors are appointed by the President and confirmed by
the Senate for 14-year terms. The other five are presidents
of the Reserve banks. The president of the Federal Reserve
Bank of New York always votes on the FOMC, and the other
four positions rotate as one-year terms among the other
eleven presidents.
An explanation of monetary policy can be systematically
done using balance
sheets.
1Since the 1990s most banks have
met their reserve requirements with their vault cash. Three
factors that have led to this situation are reductions in
reserve requirements, the use of sweep accounts to minimize
transactions balances, and the increase in ATMs. If you want
more information, here are two places to start:
www.clevelandfed.org/banking/credit_risk_management/reserves/clearing_balances.cfm
and www.ustreas.gov/press/releases/ls600.htm.
A bank that had met reserve requirements with cash still
needed to hold deposits at the Fed for check clearing, but
these deposits were not considered reserves but were
classified as contractual clearing balances.
2The Federal Reserve has
changed reserve in recent years for various reasons, but
these reasons have not included monetary policy. Today
reserve requirements are so low that many banks meet them
with vault cash.
3Why talk about three policy
tools when only one is of any real importance? For two
reasons. First, in the past the other two were used. Second,
all economic textbooks talk about these three, so to ignore
two of them could confuse those who are also using other
sources to learn economics. A fourth policy tool that the
Fed began using in 2008 is discussed in a later
section.
4These transactions are
totally distinct from sales of Treasury securities in which
the Federal Reserve acts as an agent of the Treasury in
marketing its debt. Such sales are into the primary
market.
5 The transaction here would
be done electronically, with no paper involved. All really
large transactions in the U.S. skip the paper.
