reserve requirement


Reserve Ratios

The liquid assets that a central bank or other body mandates that a bank keep at all times. The reserve ratio is expressed as a percentage of the bank's total deposits. The reserve ratio exists to ensure that the bank is able to pay an unusually high number of withdrawals on demand accounts should that event occur. It also helps ensure that the bank does not over-leverage itself. In some countries, increasing or decreasing reserve ratios may be used to help control the money supply.

reserve requirement

The required percentage of reserves (deposits) that banks and thrifts must hold in cash or in deposits at the Federal Reserve. This requirement is set by the Fed. Any changes in the required percentage are used to influence credit conditions. An increased percentage requirement means fewer funds available for lending and a resultant rise in interest rates. See also monetary policy.

Reserve requirement.

The Federal Reserve requires its member banks to keep a certain percentage of their customer deposits in cash and other liquid assets in reserve at all times.

The required percentage may be revised at the Fed's discretion, but it has not been changed in recent years.

When a bank finds itself with excess reserves, it can lend them to other banks that may need them. These very short-term loans are known as federal funds and the interest rate the lenders charge is called the federal funds rate. That's also the benchmark rate for many corporate and international government loans.
