What is the Bank Reserve Requirement?
A Bank Reserve Requirement is a regulatory mandate that requires commercial banks to hold a certain percentage of their deposits as reserves—either in their vaults or with the central bank. It ensures liquidity, stability, and the smooth functioning of the financial system.
Definition
The Bank Reserve Requirement is the minimum amount of cash that banks must keep on hand relative to customer deposits. It prevents banks from lending out all their funds and helps manage credit creation and monetary stability.

Understanding the Bank Reserve Requirement
Reserve requirements are a cornerstone of fractional-reserve banking. Banks lend out a portion of deposits while holding a fraction as reserves. This magnifies money supply through the credit multiplier effect.
Central banks adjust reserve ratios to influence economic conditions. In times of recession, lowering the ratio increases lending and stimulates growth. Conversely, raising it restricts lending and helps control inflation.
Some modern central banks, such as the Federal Reserve since 2020, have reduced reserve requirements to zero, relying instead on other tools like interest on reserve balances (IORB) and open market operations.
Formula (If Applicable)
Required Reserves = Reserve Ratio × Total Deposits
Real-World Example
- Federal Reserve (2020): Reduced reserve requirement to 0% to support liquidity during the COVID-19 crisis.
- People’s Bank of China: Frequently adjusts reserve ratios to influence credit conditions.
- Bangladesh Bank & African Central Banks: Use reserve ratios to manage currency stability and inflation.
Importance in Business and Economics
Reserve requirements influence money supply, lending, credit growth, and interest rates. They help stabilize financial systems by ensuring banks maintain adequate liquidity buffers to meet depositor needs.
