Understanding Excess Reserves

Excess reserves are funds that banks hold in addition to the required reserves. These reserves provide banks with flexibility to meet unexpected withdrawals, make loans, or invest in other assets. Banks typically earn interest on excess reserves held at the central bank.

When is Excess Reserves Useful?

  • During financial crises when deposit outflows increase
  • When banks need to prepare for regulatory examinations
  • When interest rates on excess reserves are attractive

Important Notes

The required reserve ratio is typically set by the central bank (like the Federal Reserve in the U.S.) and can change based on monetary policy goals. Banks must maintain at least the required reserve amount, but may hold more for operational purposes.
