How the Federal Reserve’s Interest Rate Mechanism Really Works

The Federal Reserve’s benchmark interest rate, often referred to as the federal funds rate, is the rate at which banks lend reserves to each other overnight. The Fed influences this rate through open‑market operations: buying securities adds reserves to the banking system, pushing the rate down; selling securities withdraws reserves, nudging the rate up. The target rate guides other rates—mortgages, car loans, and savings accounts—through market expectations. When the Fed raises the target, borrowing becomes more expensive, slowing inflation; when it lowers the target, credit becomes cheaper, stimulating spending. Recent minutes from the Federal Open Market Committee reveal that the Fed is balancing inflation concerns with the risk of a recession, explaining why the rate has hovered near the 5‑% mark for the past year.
