Investopedia explains Federal Open Market Committee - FOMC
The FOMC meets eight times per year to set key interest rates, such as the discount rate, and to decide whether to increase or decrease the money supply, which the Fed does by buying and selling government securities. For example, to tighten the money supply, or decrease the amount of money available in the banking system, the Fed sells government securities. The meetings of the committee, which are secret, are the subject of much speculation on Wall Street, as analysts try to guess whether the Fed will tighten or loosen the money supply, thereby causing interest rates to rise or fall.
