open-market operation

an instrument of MONETARY POLICY involving the sale or purchase of government TREASURY BILLS and BONDS as a means of controlling the MONEY SUPPLY. If, for example, the monetary authorities wish to increase the money supply, then they will buy bonds from the general public. The money paid out to the public will increase their bank balances. As money flows into the banking system, the banks’ liquidity is increased, enabling them to increase their lending. This results in the multiple creation of new bank deposits and, hence, an expansion of the money supply.
