Interest on reserves is the Fed's primary tool for influencing the money supply. A decrease in the interest rate on reserves tends to encourage banks to hold less reserves.

Interest on reserves is the Fed's primary tool for influencing the money supply. An increase in the interest rate on reserves tends to encourage banks to hold more reserves.

A lower interest rate increases the incentive to borrow funds from the Federal Reserve, thereby increasing the quantity of reserves in the banking system, which causes the money supply to increase.

When the Federal Reserve loans more funds to banks and other financial institutions, the quantity of reserves in the banking system increases and the money supply increases.
