What Are Federal Funds?
Federal funds are reserve balances that eligible institutions lend to one another, usually overnight, in the federal funds market. The interest rate on those transactions is the federal funds rate.
The term is often confused with government spending or federal grants. In monetary-policy context, federal funds are bank reserves, not budget funds appropriated by Congress.
Key Takeaways
- Federal funds are reserve balances lent among eligible institutions.
- Federal funds transactions are typically unsecured and overnight.
- The effective federal funds rate is a key short-term money-market rate.
- The FOMC sets a target range for the federal funds rate, not every market rate directly.
How the Market Works
Institutions with reserve balances may lend to institutions that want reserves. The transactions are generally short term, often overnight. The effective federal funds rate reflects actual transactions in this market and is watched as a measure of whether Fed policy implementation is working.
Term | Meaning |
|---|---|
Federal funds | Reserve balances lent in the federal funds market. |
Effective federal funds rate | The market rate calculated from actual transactions. |
Target range | The FOMC’s desired range for the federal funds rate. |
IORB | Administered rate that helps control short-term rates. |
Why It Affects Borrowers and Savers
Consumers usually do not borrow federal funds directly. The effect comes through the wider interest-rate system. When the expected path of the federal funds rate changes, banks, bond markets, and lenders adjust other rates, including savings yields, credit-card APRs, auto-loan rates, mortgage rates, and business borrowing costs.
The relationship is not one-for-one. Longer-term rates also reflect inflation expectations, growth expectations, credit risk, and investor demand.
Federal Funds Versus Fed Funds Rate
Federal funds are the balances being lent. The federal funds rate is the interest rate on those loans. The FOMC does not lend federal funds to consumers; it sets a target range for the rate in this institutional market, and other rates respond through banks, markets, and expectations.
The Bottom Line
Federal funds are the reserve balances traded in a key overnight money market. The market is small in direct consumer terms but central to how Fed policy moves through the financial system.
