How the Federal Reserve Sets Interest Rates—and How They Reach You
The Federal Reserve does not set one interest rate for the entire economy. Its main policy lever is the federal funds rate, the rate banks charge one another for overnight loans of reserves held at the Fed. The Federal Open Market Committee (FOMC), made up of Fed governors and regional Fed presidents, meets about eight times a year. It sets a target range for that rate—usually moving in quarter-point steps—based on its dual mandate: maximum employment and stable prices, defined as 2% inflation over time. When inflation is too high or the economy is overheating, the FOMC raises the target. When unemployment is rising or inflation is too low, it cuts.
The Fed cannot simply announce a rate and make every bank obey. It uses tools to keep the actual federal funds rate inside the target range. The most important is interest on reserve balances (IORB): the rate the Fed pays banks for deposits parked at the central bank. Because banks will not lend reserves overnight for much less than they can earn risk-free at the Fed, IORB sets a floor under market rates. The overnight reverse repurchase facility (ON RRP) does similar work for money market funds and other eligible counterparties. The New York Fed’s trading desk also buys and sells securities to fine-tune reserves. Together, these tools steer short-term money market rates.
From there, the decision ripples outward. The federal funds rate is the benchmark for the price of short-term money. Banks’ prime rate—often the fed funds target plus about 3 percentage points—moves almost immediately. Many consumer loans are tied to prime or to SOFR, the Secured Overnight Financing Rate, which tracks short-term Treasury repo markets. Credit card APRs, home equity lines of credit, and many small business loans are variable and adjust within weeks, sometimes within one or two billing cycles. Auto loan rates also respond, though lenders consider competition, credit risk, and their own funding costs. Federal student loan rates are fixed for the life of the loan but are reset each year based on the 10-year Treasury note; private student loans may be fixed or variable.
Long-term rates work differently. The Fed’s target affects only overnight lending directly. Mortgage rates, for example, track the 10-year Treasury yield and the spread investors demand for mortgage-backed securities. That means mortgage rates often move before the Fed acts, because markets anticipate policy. If investors expect the Fed to raise rates to fight inflation, long-term yields and mortgage rates may rise in advance. If they expect cuts, mortgage rates may fall before the FOMC meets. Existing fixed-rate mortgages do not change when the Fed moves; only new mortgages or adjustable-rate loans are affected.
For ordinary borrowers, the practical effects are straightforward. When the Fed raises rates, variable debt becomes more expensive quickly. Credit card minimum payments may rise if the APR climbs. New auto loans, personal loans, and mortgages cost more. Businesses face higher borrowing costs, which can slow hiring and investment. When the Fed cuts, the reverse happens, though not always instantly. Savers also feel the shift: yields on savings accounts, CDs, and money market funds tend to rise after hikes and fall after cuts, though banks may pass changes through slowly.
The process is not mechanical. Lenders add risk premiums based on credit scores, income, collateral, and market competition. Monetary policy also works with long and variable lags—often a year or more—before it fully affects spending, hiring, and inflation. So the Fed sets a short-term target, markets translate it into a spectrum of rates, and borrowers ultimately experience it through their monthly payments. The Fed’s decision is the starting point; the loan officer, bond market, and your credit profile determine where you land.
