Step-by-step explanation:
The Federal Reserve Act of 1913 gave the Federal Reserve responsibility for setting monetary policy. The Federal Open Market Committee (FOMC), the 12-member group, that formulates monetary policy for the Federal Reserve System, meets in Washington, D.C., usually eight times a year.
The Board of Governors of the Federal Reserve System provides oversight to the 12 Reserve Banks and their branches. The Federal Open Market Committee (FOMC), the Fed's monetary policymaking body, is made up of the members of the Board of Governors and presidents of the Reserve Banks.
