The federal funds rate is the interest rate banks charge each other to borrow money overnight. It serves as the baseline interest rate for the entire U.S. economy, influencing everything from credit card APRs to savings account yields. The Federal Open Market Committee (FOMC), the policy-setting arm of the Federal Reserve, sets a target range for this rate and adjusts it to steer the economy toward stable prices and healthy employment.
How the Federal Funds Rate Works
Banks are required to hold a certain amount of money in reserve. At the end of each business day, some banks have more reserves than they need while others fall short. Banks with excess reserves lend to those running low, and the interest rate on these overnight loans is the federal funds rate.
The FOMC doesn’t set one exact number. Instead, it establishes a target range, currently 3.5% to 3.75% as of its January 29, 2026 decision. The actual rate that emerges from all overnight lending activity on a given day is called the effective federal funds rate, and it floats within that range.
To keep the effective rate inside the target range, the Federal Reserve uses two main tools: the interest rate it pays banks on reserve balances held at the Fed, and the interest rate on its overnight reverse repurchase facility (essentially short-term lending from the Fed). By adjusting these rates, the Fed makes it more or less attractive for banks to lend reserves to each other at a particular price, nudging the market rate where it wants it.
Why the Fed Raises or Lowers It
Congress gave the Federal Reserve a dual mandate: promote maximum employment and maintain stable prices. The federal funds rate is the primary lever for balancing those two goals.
When inflation runs too high, the FOMC raises the target range. Higher borrowing costs slow spending and business investment, which cools demand and brings prices back down. The Fed’s longer-run inflation target is 2%, measured by the annual change in the Personal Consumption Expenditures (PCE) price index. When inflation climbs well above that mark, rate increases typically follow.
When the economy weakens and unemployment rises, the FOMC lowers the target range. Cheaper borrowing encourages consumers and businesses to spend, hire, and invest, which supports job growth. Maximum employment doesn’t mean zero unemployment; it means the lowest unemployment rate the economy can sustain without triggering runaway inflation. The Fed watches a broad set of labor market indicators, not a single unemployment number, to judge how close the economy is to that point.
How It Affects Your Finances
The federal funds rate is a wholesale rate between banks, so you’ll never pay it directly. But it ripples outward into nearly every interest rate you encounter.
Short-term rates feel the effect most quickly. When the Fed raises its target range, banks face higher costs for overnight borrowing, and they pass those costs along. The prime rate, which most banks use as a starting point for pricing variable-rate loans, moves almost in lockstep with the federal funds rate. That means several consumer products respond relatively fast:
- Credit cards. Most credit cards carry variable APRs tied to the prime rate. A higher federal funds rate pushes your card’s interest charges up within a billing cycle or two.
- Home equity lines of credit (HELOCs). These typically have variable rates pegged to the prime rate, so monthly payments shift when the Fed moves.
- Adjustable-rate mortgages. If your mortgage rate resets periodically, it will reflect changes in short-term benchmarks influenced by the federal funds rate.
- Auto loans. New auto loan rates tend to track short-term rate movements, though the exact impact depends on your credit profile and the lender.
- Savings accounts and CDs. Banks also adjust what they pay depositors. When rates rise, yields on high-yield savings accounts and certificates of deposit generally climb as well, though banks are often slower to raise deposit rates than loan rates.
Where the Effect Fades
Not every rate moves in tandem with the federal funds rate. Fixed-rate 30-year mortgages, for instance, are among the least directly affected. Their pricing depends more on long-term factors like investor expectations for inflation over the next decade and demand for long-term Treasury bonds. That’s why you can sometimes see the Fed cutting its target range while 30-year mortgage rates hold steady or even rise.
Longer-term Treasury securities and corporate bonds also respond to a broader mix of forces. The federal funds rate sets the floor for short-term borrowing costs, but market sentiment, global capital flows, and inflation forecasts play a bigger role as the time horizon stretches out.
How FOMC Decisions Happen
The FOMC meets eight times a year on a predetermined schedule, with additional emergency meetings possible if conditions demand it. At each meeting, members review economic data on employment, inflation, consumer spending, and financial conditions, then vote on whether to raise, lower, or hold the target range steady.
After each meeting, the committee releases a policy statement explaining its decision. The chair also holds a press conference to provide context. Markets pay close attention to the language in these statements, because even subtle wording changes can signal where rates are headed next. Between meetings, speeches by Fed governors and regional bank presidents offer additional clues about the committee’s thinking.
Rate changes usually come in increments of 0.25 percentage points, though the Fed has moved by 0.50 or even 0.75 points during periods of rapid inflation or economic stress. Each adjustment filters through the banking system within days, reaching consumer rates over the following weeks.
