Federal Funds Rate
Federal Funds Rate
Quick Definition
The federal funds rate is the target interest rate set by the Federal Open Market Committee (FOMC) at which commercial banks lend their excess reserve balances to other banks on an overnight basis. It is the primary tool of U.S. monetary policy and serves as the benchmark from which virtually all other interest rates in the economy are derived.
What It Means
The federal funds rate is the most influential interest rate in the global financial system. When the Federal Reserve raises or lowers this rate, it sets off a chain reaction through every corner of the economy: mortgage rates, credit card rates, auto loan rates, savings account yields, corporate borrowing costs, and the present value of all financial assets are all affected.
Banks are required to hold a certain amount of reserves. When one bank has excess reserves and another has a shortfall, the bank with excess reserves lends to the shortfall bank overnight — charging the federal funds rate. The Fed does not directly set this rate; it sets a target range and uses its policy tools (IOER, reverse repos) to keep the actual rate within that range.
The Fed Funds Rate and the Prime Rate
The prime rate is directly linked to the federal funds rate:
Prime Rate = Federal Funds Rate + 3.00%
When the Fed funds rate is 5.50%, the prime rate is 8.50%. Most variable-rate consumer and business loans are priced at Prime plus or minus a spread:
| Loan Type | Typical Rate |
|---|---|
| Credit cards | Prime + 12-16% |
| Home equity line of credit (HELOC) | Prime + 0-2% |
| Small business loans | Prime + 2-5% |
| Auto loans | Fed funds based (not directly Prime) |
| 30-year fixed mortgage | 10-year Treasury + 1.5-2% (not directly Prime) |
Rate Decision Timeline
The FOMC meets 8 times per year (approximately every 6 weeks) to set the federal funds rate target range. Between meetings, the rate remains constant unless the FOMC calls an emergency meeting.
How rate decisions are made:
- FOMC members review economic data: employment, inflation (CPI, PCE), GDP, wages
- Two days of deliberation at each meeting
- Vote on whether to raise, lower, or hold the rate
- Decision announced at 2:00 PM ET on the second day
- Press conference follows at 2:30 PM ET

Impact on Asset Classes
| Asset | Rising Rate Environment | Falling Rate Environment |
|---|---|---|
| Short-term bond prices | Fall modestly | Rise modestly |
| Long-term bond prices | Fall sharply | Rise sharply |
| Bank stocks | Benefit (higher net interest margin) | Hurt (compressed margins) |
| Growth/tech stocks | Hurt (higher discount rates) | Benefit (lower discount rates) |
| Real estate | Hurt (higher mortgage rates) | Benefit (lower mortgage costs) |
| Savings account yields | Rise | Fall |
| US dollar | Strengthens | Weakens |
| Gold | Often falls | Often rises |
The Taylor Rule: A Framework for Setting Rates
The Taylor Rule is an influential formula that estimates the appropriate federal funds rate based on economic conditions:
Taylor Rule: Federal Funds Rate = 2% + Inflation + 0.5(Inflation - 2%) + 0.5(Output Gap)
Where:
- 2% = estimated neutral real rate
- Inflation = current inflation rate
- 2% = inflation target
- Output gap = % difference between actual and potential GDP
When inflation is above target or GDP is above potential, the rule suggests higher rates. Below target or potential, lower rates. In 2022, the Taylor Rule implied a rate of 9%+ — validating the Fed's aggressive hiking pace.
Real vs. Nominal Federal Funds Rate
The real federal funds rate adjusts for inflation:
Real Rate = Nominal Rate - Inflation Rate
| Period | Nominal Rate | Inflation (PCE) | Real Rate |
|---|---|---|---|
| 2021 | 0.25% | 5.8% | -5.55% (extremely stimulative) |
| 2022 | 3.00% | 5.5% | -2.5% (still very stimulative) |
| 2023 | 5.33% | 3.3% | +2.0% (finally restrictive) |
| 2024 | 5.33% | 2.5% | +2.8% (meaningfully restrictive) |
A negative real rate means monetary policy is stimulative — borrowers are being paid to borrow in real terms. A positive real rate means policy is restrictive — borrowing has a real cost that discourages spending and investment.
Key Points to Remember
- The federal funds rate is set by the FOMC at 8 meetings per year and is the most important interest rate in the world
- Prime rate = Fed funds + 3% — directly drives HELOCs, credit cards, small business loans
- Rate hikes fight inflation by raising borrowing costs; rate cuts stimulate by lowering them
- Fixed mortgage rates track the 10-year Treasury yield, not the fed funds rate directly
- The real fed funds rate (nominal minus inflation) determines whether policy is truly restrictive or stimulative
- Announcements at 2:00 PM ET on FOMC decision days are among the most market-moving events of the year
Frequently Asked Questions
Q: Does the fed funds rate directly determine my mortgage rate? A: Not directly. The 30-year fixed mortgage rate tracks the 10-year Treasury yield, not the fed funds rate. However, when the Fed raises rates, it generally pushes up all yields including the 10-year Treasury, which indirectly raises mortgage rates. The relationship is real but not mechanical.
Q: Why does the Fed set a range rather than a single rate? A: Since 2008, the Fed sets a target range (e.g., "5.25-5.50%") rather than a single target. This acknowledges that the actual rate in the overnight market will fluctuate within the range and gives the Fed flexibility. The actual effective fed funds rate is published daily by the New York Fed.
Q: What is the "neutral" interest rate? A: The neutral (or "natural") rate is the theoretical federal funds rate that neither stimulates nor restrains economic growth while keeping inflation at the 2% target. It is unobservable directly and estimated to be around 2.5-3% nominal (0.5% real). When the actual rate exceeds neutral, monetary policy is restrictive; below neutral, it is accommodative.
