Central banks have a wide range of responsibilities - from overseeing monetary policy to implementing specific goals such as currency stability, low inflation and full employment.

Investopedia Commentary
The central banking system in the U.S. is known as the Federal Reserve System (commonly known as "the Fed"), which is composed of twelve regional Federal Reserve Banks located in major cities throughout the country. The main tasks of the Federal Reserve are to supervise and regulate banks, implement monetary policy by buying and selling U.S. Treasury bonds (T-bills), and steering interest rates. Alan Greenspan currently serves as the Chairman of the Board of Governors of the Federal Reserve.
