The Federal Open Market Committee (FOMC) is a committee within the Federal Reserve System that is charged under United States law with overseeing the nation's open market operations. This Federal Reserve committee makes key decisions about interest rates and the growth of the United States money supply. Under the terms of the original Federal Reserve Act, each of the Federal Reserve banks was authorized to buy and sell in the open market bonds and short term obligations of the United States Government, bank acceptances, cable transfers, and bills of exchange. Hence, the reserve banks were at times bidding against each other in the open market. In 1922, an informal committee was established to execute purchases and sales. The Banking Act of 1933 formed an official FOMC.

The Federal Reserve System is the central banking system of the United States. It was created on December 23, 1913, with the enactment of the Federal Reserve Act, after a series of financial panics led to the desire for central control of the monetary system in order to alleviate financial crises. Over the years, events such as the Great Depression in the 1930s and the Great Recession during the 2000s have led to the expansion of the roles and responsibilities of the Federal Reserve System.
