The main tool of monetary policy is open market operations.
The Federal Reserve uses open market operations (OMOs), which are central banks' purchases and sales of assets on the open market, as a key tool for carrying out monetary policy. The Federal Open Market Committee establishes the short-term goal for open market operations (FOMC).
