The primary responsibility of the Board members is the formulation of monetary policy. The seven Board members constitute a majority of the 12-member Federal Open Market Committee (FOMC), the group that makes the key decisions affecting the cost and availability of money and credit in the economy. The other five members of the FOMC are Reserve Bank presidents, one of whom is the president of the Federal Reserve Bank of New York. The other Bank presidents serve one-year terms on a rotating basis. By statute the FOMC determines its own organization, and by tradition it elects the Chairman of the Board of Governors as its Chairman and the President of the New York Bank as its Vice Chairman.
