Open market operations are the most
important means of expanding and contracting
money supplies in modern monetary
systems regulated by central banks.
Central banks, such as the Federal
Reserve System in the United States,
regulate money supplies as a means of
maintaining economic stability and price
stability.
To infuse additional money into the
U.S. economy, the Federal Reserve System
purchases U.S. government bonds,
paying for the bonds with freshly created
funds added to commercial bank
deposits at any of the twelve Federal
Reserve Banks. Commercial bank
deposits at Federal Reserve Banks, coupled
with vault cash, make up what is
called “high-powered money,” because a
system of commercial banks, making
loans, can expand customer demand
deposits by some multiple of the volume
of high-powered money.
To withdraw money from circulation
in the U.S. economy, the Federal
Reserve system sells from its holdings of
U.S. government bonds, and withdraws
the proceeds of the sales from circulation
and the banking system, leading to a
contraction of money supplies.
The Bank of England may have been
the first to regulate credit markets along
the lines of modern open market operations.
Late in the 19th century, the Bank
of England would borrow funds in the
London money market as a means of
raising interest rates.
The Federal Reserve System apparently
discovered by accident the practice
of open market operations as an instrument
of monetary control. The Federal
Reserve Act of 1913 did not specifically
address open market operations but did
empower individual Federal Reserve
Banks to buy and sell securities along
the lines set forth by the rule sand regulations
of the the Federal Reserve Board.
An economic slowdown in the 1920s
reduced the demand for Federal Reserve
Bank loans to commercial banks.
Federal Reserve Banks began buying
government securities in the open market
as a means of acquiring incomeearning
assets, compensating for the loss
in the discount loan business to commercial
banks. At first, individual Federal
Reserve Banks separately purchased
government securities, occasionally pitting
individual banks against each other
in bidding for securities. The Federal
Reserve Banks collectively decided to
coordinate all purchases of government
securities through the New York Federal
Reserve Bank. In 1922, the then Federal
Reserve Board, since renamed the Board
of Governors of the Federal Reserve
System, established a special committee,
composed of board members and officials
of the Federal Reserve Banks, to
make decisions about open market operations.
The comparable committee is
now called the Federal Open Market
Committee.
The Federal Reserve Banks soon
learned the impact of open market operations
on money supplies, interest rates,
and credit conditions, but the board
remained split on the wisdom of open
market operations until the 1930s. During
the Great Depression of the 1930s,
open market operations began to play a
larger role in monetary policy. By the
end of World War II, open market operations
had become the most important
tool in the central bank arsenal of monetary
controls.
