What Are Fed Funds?
Fed funds refer to the reserve balances that depository institutions hold at Federal Reserve Banks. These are the balances banks lend to each other, typically on an overnight lending basis, to meet their liquidity needs or to earn interest on excess reserves. The interest rate at which these transactions occur is known as the federal funds rate, a critical benchmark in the U.S. financial system and a cornerstone of the Federal Reserve's monetary policy. The federal funds rate directly influences other interest rates throughout the economy, making the movements of fed funds closely watched by investors, businesses, and consumers alike.
History and Origin
The federal funds market originated in the 1920s as banks with excess reserve balances at the Federal Reserve began lending these funds to banks with deficits. Early federal funds loans were made between New York City banks in the summer of 1921. By the 1960s, the Federal Reserve began actively monitoring the federal funds rate to assess money market conditions. The Federal Open Market Committee (FOMC) formally adopted explicit targets for the federal funds rate in the 1970s, establishing it as a primary tool for conducting monetary policy. Since the 2008 financial crisis, the Federal Reserve's approach to managing the federal funds rate has evolved, notably with the introduction of interest payments on reserve balances (IORB), which now serves as a key mechanism for guiding the effective federal funds rate within the FOMC's target range.4
Key Takeaways
- Fed funds are the balances banks hold at Federal Reserve Banks and lend to each other overnight.

- The effective federal funds rate (EFFR) is a volume-weighted median of actual overnight federal funds transactions.
Interpreting the Fed Funds Rate
The federal funds rate is a crucial indicator of the overall "easiness or tightness" of money in the U.S. economy. When the Federal Open Market Committee raises the target range for the federal funds rate, it generally signals a tighter monetary policy stance, aiming to slow down inflation or prevent the economy from overheating. Conversely, a lower target range suggests a more accommodative monetary policy, designed to stimulate economic growth and encourage borrowing and spending. The published effective federal funds rate (EFFR) reflects the average rate at which these overnight loans occur, providing real-time insight into the supply and demand for liquidity within the banking system. Market participants interpret movements in the EFFR and the FOMC's target to gauge the central bank's intentions regarding future economic conditions and monetary policy direction.
Hypothetical Example
Imagine two commercial banks, Bank A and Bank B, at the end of a business day. Bank A finds itself with excess reserve balances at the Federal Reserve, exceeding its required reserves. Meanwhile, Bank B has a temporary shortfall in its reserves and needs to acquire funds to meet its requirements.
Bank A, seeking to earn a return on its surplus, lends $10 million in fed funds to Bank B overnight. The two banks negotiate an interest rate for this overnight loan, for example, 5.25%. The next morning, Bank B repays Bank A the $10 million plus the agreed-upon interest. This individual transaction, along with countless others occurring across the financial system, contributes to the calculation of the effective federal funds rate. If many banks have excess reserves and few need to borrow, the rate tends to fall. If many banks need to borrow and fewer have excess, the rate tends to rise.
Practical Applications
The federal funds rate has widespread practical applications across financial markets and the broader economy. It serves as the primary operational target for the Federal Reserve's monetary policy. Changes in this rate ripple through the financial system, influencing a variety of other borrowing costs, including interest rates on mortgages, credit cards, and business loans. For investors, the federal funds rate is a key economic indicator that provides insight into the Federal Reserve's stance on inflation and economic growth. For instance, when the Fed raises the federal funds rate target, it typically leads to higher short-term rates across the board, which can impact the profitability of financial institutions and the attractiveness of different asset classes. The Federal Reserve Bank of St. Louis's FRED database provides historical data on the Effective Federal Funds Rate (EFFR), which is often referenced by analysts and economists.3
Limitations and Criticisms
While central to U.S. monetary policy, the federal funds rate and its role have faced limitations and criticisms, particularly in times of economic distress. One notable challenge emerged during and after the 2008 financial crisis, when the Federal Reserve lowered the federal funds rate to near zero, reaching what is known as the "zero lower bound." At this point, traditional monetary policy tools that rely on adjusting short-term interest rates become less effective, as nominal rates cannot realistically go significantly negative. This compelled the Fed to employ unconventional measures, such as quantitative easing, to further stimulate the economy.2
Furthermore, critics have debated the effectiveness of interest rate-based monetary policy in achieving desired economic outcomes, especially when economic conditions are challenging or when factors other than interest rates heavily influence consumer and business behavior. There can also be challenges in distinguishing between nominal and real interest rates, which can lead to misinterpretations of the policy stance if inflation expectations are not properly accounted for.1 The market for fed funds itself has also evolved, with changes in reserve levels and participant behavior influencing its dynamics, which the Fed continually monitors to ensure the effective transmission of its policy.
Fed Funds vs. Discount Rate
The terms "fed funds" (specifically, the federal funds rate) and the "discount rate" are often confused, but they represent distinct mechanisms within the Federal Reserve's framework. The federal funds rate is a market-determined rate at which banks lend their excess reserves to each other overnight, with the Federal Open Market Committee (FOMC) setting a target range for this rate. It reflects the supply and demand for reserves in the interbank market.
In contrast, the discount rate is the interest rate at which eligible depository institutions can borrow money directly from the Federal Reserve through its discount window. The Federal Reserve sets this rate, and while it serves as a backstop source of liquidity for banks, borrowing from the discount window often carries a stigma, making the federal funds market the preferred avenue for routine overnight borrowing among banks. The discount rate is typically set higher than the effective federal funds rate target to encourage banks to borrow from each other first.
FAQs
Who participates in the fed funds market?
Participants in the fed funds market primarily include depository institutions such as commercial banks, savings institutions, and credit unions. Certain other entities, like government-sponsored enterprises (GSEs), also participate as lenders or borrowers of these overnight funds.
How does the Federal Reserve influence the federal funds rate?
The Federal Reserve influences the federal funds rate primarily by setting a target range and adjusting administered rates, most notably the interest rate paid on reserve balances (IORB) that banks hold at the Federal Reserve. By adjusting this rate, the Fed creates incentives for banks to lend or borrow at rates within the target range, thereby steering the effective federal funds rate.
Why is the federal funds rate important for the economy?
The federal funds rate is crucial because it serves as the benchmark for many other short-term interest rates in the economy. Changes in this rate affect the cost of borrowing for banks, which in turn influences the rates offered to consumers and businesses for loans, impacting overall spending, investment, and economic growth.
Is the federal funds rate always the same as the target rate?
No, the effective federal funds rate (EFFR) is the actual volume-weighted median rate at which overnight federal funds transactions occur, which can fluctuate daily. The Federal Open Market Committee sets a target range for the federal funds rate, and the Federal Reserve uses its tools to encourage the EFFR to stay within that range.
