When the Fed wants to increase excess reserves held by banks it does what?

When the Federal Reserve wants to increase excess reserves held by banks, it typically conducts open market operations by purchasing government securities. This action injects liquidity into the banking system, increasing the reserves that banks hold. Additionally, the Fed may lower the required reserve ratio or decrease the discount rate to encourage banks to lend more and hold excess reserves. These measures aim to stimulate economic activity by making more funds available for lending.
