Monetary Policy and the Federal Reserve

The Federal Reserve, the central bank of the United States, controls monetary policy: decisions about interest rates and the money supply. Its main tool is the target federal funds rate, the rate banks charge each other for overnight loans. Banks do not keep this cost to themselves. When the Fed raises that target, banks raise the rates they charge on mortgages, car loans, credit cards, and business loans, because their own borrowing just got more expensive. Higher rates mean borrowing costs more and saving pays more, so people and businesses spend and borrow less. That cools demand and slows inflation. Cutting rates works in reverse, making borrowing cheaper to encourage spending and investment when the economy needs a boost.

The Fed pulls this lever through three tools that all push the same direction. Open market operations, buying or selling government securities, adjust how much money is circulating in the banking system. The discount rate is what the Fed itself charges banks that borrow directly from it. Reserve requirements set how much cash banks must hold back rather than lend out. Raise any of these and credit tightens; lower them and credit loosens.

The Fed is intentionally insulated from elections. Its governors serve long, staggered terms and cannot be fired by the president for an unpopular rate decision, unlike cabinet secretaries or agency heads who serve at the president's pleasure. This connects monetary policy to the unit's broader theme: economic conditions shape public opinion and voting, but the institution managing those conditions was built to resist the short-term pressures of opinion and elections themselves.
