The following testimony was given at a hearing of the Senate Committee on Homeland Security and Governmental Affairs on December 11, 2025. The discussion centered around the Federal Reserve’s authority to pay interest on the deposits that banks hold at the Federal Reserve. This issue was previously addressed in 2004, when it was argued that not paying interest on these deposits effectively imposed a tax on banks, compelling them to make interest-free loans to the government. This tax was seen as inducing wasteful and harmful actions.
Congress eventually agreed with this assessment and authorized the payment of interest on reserves through the Regulatory Relief Act of 2006. This legislation also provided additional flexibility for the Board of Governors to reduce reserve requirements. The authorization to pay interest was initially scheduled to take effect in 2011, but Congress accelerated its implementation to 2008. This expedited timeline was necessary to support the Federal Reserve’s efforts to stabilize financial markets and the economy during and after the Global Financial Crisis of 2008-09.
The payment of interest on reserve balances (IORB) serves several critical public policy purposes. It enables the Federal Reserve to meet its Congressional monetary policy mandates for stable prices and maximum employment in certain circumstances. Additionally, IORB enhances financial stability. If Congress seeks to raise additional taxes from banks, it should do so directly rather than by forcing them to make interest-free loans to the government.
Benefits of IORB
IORB offers several positive benefits. First, it provides the Federal Reserve with a tool to influence short-term interest rates more effectively. By adjusting the interest rate paid on reserves, the Federal Reserve can control the federal funds rate more precisely, which is crucial for implementing monetary policy. Second, IORB helps to manage liquidity in the banking system. Banks can earn a return on their excess reserves, reducing the incentive to lend out these funds recklessly. This stability is particularly important during times of financial stress, as it helps prevent bank runs and maintains confidence in the financial system.
Criticisms of IORB
Critics of IORB have raised several concerns. One argument is that paying interest on reserves reduces the incentive for banks to lend to the private sector, potentially slowing economic growth. However, this view overlooks the fact that IORB allows the Federal Reserve to better control short-term interest rates, which can stimulate lending and investment when needed. Another criticism is that IORB transfers wealth from taxpayers to banks. While it is true that banks benefit from earning interest on their reserves, this cost is outweighed by the benefits of a stable financial system and effective monetary policy.
IORB in Unconventional Monetary Policies
IORB also plays a crucial role in implementing unconventional monetary policies, such as quantitative easing. During periods of economic downturn, the Federal Reserve can purchase assets to inject liquidity into the financial system. By paying interest on reserves, the Federal Reserve can control the amount of liquidity in the system more effectively, preventing inflationary pressures while stimulating economic activity.
Conclusion
In summary, the payment of interest on reserve balances is a vital tool for the Federal Reserve in achieving its monetary policy objectives. It enhances financial stability, provides better control over short-term interest rates, and supports the implementation of unconventional monetary policies. While critics may raise valid concerns, the benefits of IORB in maintaining a stable and efficient financial system outweigh the potential drawbacks. Congress should continue to support this policy to ensure the Federal Reserve can effectively fulfill its mandates for stable prices and maximum employment.
