What Are Federal Funds?
Federal funds refer to overnight borrowings between banks and other financial institutions to manage their reserve balances held at the Federal Reserve System. Within the realm of monetary policy and banking, these funds are essentially available cash balances that depository institutions lend to one another, typically on an uncollateralized, overnight basis, to meet their reserve requirements or clear transactions. The market where these transactions occur is known as the federal funds market.
When a bank has more reserves than it needs, it can lend these surplus funds to another bank that has a deficit in its reserve account. This interbank lending facilitates the efficient distribution of liquidity within the banking system, allowing banks to manage their daily cash flows and balance their accounts with the Federal Reserve.
History and Origin
The federal funds market originated in the 1920s as a mechanism for banks to manage their excess or deficient reserve positions. Early federal funds loans, facilitated primarily among New York City banks, allowed institutions anticipating shortfalls in their Federal Reserve accounts to borrow from banks with surplus balances.12 The concept gained traction as a crucial part of the broader money market, providing a flexible way for banks to adjust their reserves.11
By the 1970s, the Federal Open Market Committee (FOMC) began explicitly targeting the federal funds rate as a key tool for conducting monetary policy.10 This established the federal funds market as central to the Federal Reserve's efforts to influence broader interest rates and economic conditions.9
Key Takeaways
- Federal funds are overnight loans of reserve balances between banks and other financial institutions.
- The primary purpose of federal funds transactions is to help banks manage their reserve positions at the Federal Reserve.
- The federal funds market is a critical component of the U.S. financial system, enabling the efficient flow of liquidity.
- The Federal Reserve uses the federal funds rate, which is the interest rate on federal funds, as a primary tool for implementing monetary policy.
- Federal funds transactions do not increase or decrease the total amount of reserves in the banking system; rather, they redistribute existing reserves.
Interpreting the Federal Funds
Federal funds are interpreted as a fundamental indicator of liquidity and demand within the U.S. banking system. The willingness of banks to lend and borrow these funds reflects their individual reserve needs and the overall availability of reserves in the system. When banks are actively lending federal funds, it suggests ample liquidity, whereas increased demand or higher borrowing rates can indicate tighter money market conditions.8
The effective federal funds rate, which is the volume-weighted median of overnight federal funds transactions, is particularly important. This rate serves as the Federal Reserve's primary policy rate and is closely watched by financial market participants for insights into the central bank's monetary policy stance. Changes in the federal funds rate signal the Fed's intent regarding economic growth and inflation.
Hypothetical Example
Imagine two commercial banks: Bank A and Bank B. At the end of a business day, Bank A finds itself with an excess of $50 million in its reserve balances at the Federal Reserve, meaning it holds more than its required reserves. Meanwhile, Bank B has a temporary shortfall of $30 million in its reserves due to unexpected withdrawals or a large payment.
To avoid a penalty for falling below its reserve requirement, Bank B can approach Bank A in the federal funds market. Bank A, seeking to earn a return on its idle reserves, agrees to lend $30 million in federal funds to Bank B on an overnight basis. They negotiate an interest rate for this overnight loan, which is the federal funds rate. The transaction is typically settled via Fedwire, where the Federal Reserve debits Bank A's reserve account and credits Bank B's account with the $30 million. The next morning, Bank B repays the $30 million plus the agreed-upon interest to Bank A. This simple transaction demonstrates how federal funds facilitate daily liquidity management for depository institutions.
Practical Applications
Federal funds are central to the operations of the U.S. banking system and the implementation of monetary policy. Their practical applications are broad, influencing various aspects of the financial markets:
- Bank Reserve Management: Banks utilize the federal funds market daily to manage their statutory reserve requirements and maintain sufficient liquidity for their operations. Banks with excess reserves lend them, while those with deficits borrow, ensuring efficient capital allocation.
- Monetary Policy Implementation: The Federal Reserve primarily conducts its monetary policy by setting a target range for the federal funds rate. Through various tools, including open market operations, the Fed influences the supply of reserves in the banking system to keep the effective federal funds rate within its target range. This, in turn, influences other short-term interest rates throughout the economy.7
- Economic Indicator: The federal funds rate is one of the most closely watched economic indicators. Its level and changes signal the Federal Reserve's assessment of the economy's health, its inflation outlook, and its stance on stimulating or slowing economic growth.
- Interbank Funding: The federal funds market serves as a vital source of short-term, unsecured funding for banks. It allows institutions to quickly adjust their balance sheet positions and meet unexpected funding needs without resorting to more expensive or less flexible alternatives.
Limitations and Criticisms
While federal funds are integral to the financial system, the market and the Federal Reserve's influence over it have faced scrutiny and limitations, especially in recent years.
One significant shift occurred after the 2008 financial crisis. The Federal Reserve's large-scale asset purchases (quantitative easing) flooded the banking system with reserves, making it less necessary for many banks to borrow in the traditional federal funds market.6 This fundamentally altered the market's dynamics, with government-sponsored enterprises (GSEs) like Federal Home Loan Banks becoming more prominent lenders, as they are not eligible to earn interest on reserves held at the Federal Reserve, unlike commercial banks.5
Furthermore, critics occasionally question the Federal Reserve's overall influence on market interest rates and its role in managing economic cycles. Some arguments suggest that the Fed's policies, including those related to federal funds, can contribute to asset bubbles or economic distortions by influencing the cost of credit. For instance, political leaders have sometimes voiced strong opinions on the Federal Reserve's interest rate decisions, highlighting the public and political scrutiny faced by the central bank's actions.4
Federal Funds vs. Federal Funds Rate
The terms "Federal Funds" and "Federal Funds Rate" are distinct but closely related, and are often a source of confusion.
Federal Funds refer to the actual cash balances—the reserves—that commercial banks and other eligible entities lend to and borrow from one another, typically on an overnight basis. These are the funds themselves that are transferred between accounts at the Federal Reserve.
The Federal Funds Rate is the target interest rate set by the Federal Open Market Committee (FOMC) of the Federal Reserve. It is the weighted average interest rate at which these overnight federal funds transactions occur. While the Federal Reserve sets a target range for this rate, the actual rate is determined by the forces of supply and demand in the federal funds market. The Federal Funds Rate is a key benchmark that influences many other interest rates throughout the economy, including those on mortgages, credit cards, and other consumer loans.
In3 essence, federal funds are the object of the transaction, while the federal funds rate is the price of that transaction.

Changes in this rate influence other interest rates across the economy, affecting borrowing costs for businesses and consumers, and thereby impacting investment, spending, and overall economic activity.
##2# Are federal funds collateralized?
No, federal funds are typically unsecured loans. This means they are not backed by collateral.
How does the Federal Reserve influence federal funds?
The Federal Reserve influences the federal funds market primarily by setting a target range for the federal funds rate. It achieves this by adjusting administered rates, such as the interest rate it pays on banks' reserve balances, and by conducting open market operations to adjust the supply of reserves in the banking system.1
