An open market operation is a primary tool used by a central bank to manage liquidity within the banking system. By engaging in these transactions, the central bank influences the amount of money available to commercial banks, which in turn affects broader economic conditions.
These operations typically involve the purchase or sale of government bonds and other financial assets. Alternatively, central banks may utilize repurchase agreements or secured lending, where they make fixed-period deposits at commercial banks. These transactions are often secured by collateral, ensuring the stability of the exchange and allowing the central bank to effectively implement its monetary policy goals.
