The Federal Open Market Committee (FOMC), a committee within the Federal Reserve System (the Fed), is charged under the United States law with overseeing the nation's open market operations (i.e., the Fed's buying and selling of United States Treasury securities). This Federal Reserve committee makes key decisions about interest rates and the growth of the United States money supply.
The FOMC is the principal organ of United States national monetary policy. The Committee sets monetary policy by specifying the short-term objective for the Fed's open market operations, which is usually a target level for the federal funds rate (the rate that commercial banks charge between themselves for overnight loans).
The FOMC also directs operations undertaken by the Federal Reserve System in foreign exchange markets, although any intervention in foreign exchange markets is coordinated with the U.S. Treasury, which has responsibility for formulating U.S. policies regarding the exchange value of the dollar.
The Committee consists of the seven members of the Federal Reserve Board, four of eleven Federal Reserve Bank presidents, serving one year terms, and the president of the Federal Reserve Bank of New York. The Federal Open Market Committee was formed by the Banking Act of 1933 (codified at 12 U.S.C. § 263), and did not include voting rights for the Federal Reserve Board of Governors. The Banking Act of 1935 revised these protocols to include the Board of Governors and to closely resemble the present-day FOMC, and was amended in 1942 to give the current structure of twelve voting members.
