Interest on Reserve Balances (IORB) refers to the interest rate that central banks pay to financial institutions on their reserve balances held at the central bank. These reserves are deposits that commercial banks maintain with the central bank to meet regulatory requirements or for operational needs.
On October 1, 2011, the Federal Reserve Banks were authorized by the Financial Services Regulatory Relief Act of 2006 to pay interest on balances held by or on behalf of qualified institutions in Reserve Bank master accounts. The Emergency Economic Stabilization Act of 2008 advanced this authority to October 1, 2008.
The Board determines the interest rate on reserve balances (IORB rate), making it an essential tool for the Federal Reserve’s monetary policy.
Example: Suppose Bank A holds $1 billion in reserve balances at the Federal Reserve. If the IORB rate is 2%, the Federal Reserve pays Bank A $20 million annually for maintaining these reserves.
IORB serves as an incentive, influencing how financial institutions allocate their funds and shaping broader economic activity.

How Interest on Reserve Balances Impacts Monetary Policy
Central banks, like the Federal Reserve, use IORB to steer short-term interest rates and control liquidity in the financial system. Here’s how it works:
- Setting a Floor for Market Rates: By offering interest on reserves, central banks create a floor for short-term market interest rates. Banks avoid lending at rates below the IORB since they can earn a risk-free return by holding reserves.
- Managing Inflation and Economic Growth: Adjusting the IORB rate allows central banks to influence borrowing and spending. For instance, higher IORB rates discourage lending and spending, reducing inflationary pressures, and lower IORB rates encourage lending and investment, boosting economic growth.
Example: During an economic slowdown, a central bank might lower the IORB rate to encourage banks to lend more, stimulating business activity and consumer spending.
Why Central Banks Use Interest on Reserve Balances as a Tool
IORB is a useful tool in the monetary policy toolbox due to its direct impact on the banking sector. Key reasons for its use include:
Liquidity Management: IORB helps central banks manage excess liquidity in the financial system without relying solely on open market operations.
Operational Simplicity: Interest payments on reserves offer a straightforward way to influence interest rates without adding complexity to monetary policy frameworks.
Financial Stability: Stabilizing short-term interest rates through IORB creates a predictable financial environment, benefiting both lenders and borrowers.
Interest on Reserve Balances vs. Other Monetary Tools
Even though IORB is highly effective, it is often combined with other financial instruments. Here’s how it compares:
| Tool | Function | Example |
|---|---|---|
| Interest on Reserves | Sets a floor for short-term interest rates and influences bank lending behaviors. | Federal Reserve’s IORB rate adjustment to combat inflation. |
| Open Market Operations | Buying or selling government securities to adjust the money supply. | Fed purchasing Treasury bonds during quantitative easing. |
| Discount Rate | Rate at which central banks lend directly to commercial banks. | Raising the discount rate to deter borrowing during overheating economies. |
Interest on Reserve Balances is more than just a technical tool; it’s a cornerstone of modern monetary policy. The Board updates the current IORB rate in the table below and in the Data Download Program (DDP). They update these resources each business day at 4:30 p.m., Eastern Time, to show the next business day’s rate. Federal holidays do not include updates.
