What the Fed is
The Federal Reserve ("the Fed") is the central bank of the United States, created by Congress in 1913. It's deliberately structured to be independent of day-to-day politics — its decisions don't require approval from the President or Congress — so that it can make unpopular choices (like raising rates) when the economy needs them (Federal Reserve — about the Fed).
It's made up of a central Board of Governors in Washington plus 12 regional Reserve Banks, and its policy decisions are made by a committee called the FOMC (Federal Open Market Committee).
Its job: the dual mandate
Congress gave the Fed two primary goals, known as the dual mandate (Federal Reserve — monetary policy & the dual mandate):
- Stable prices — keeping inflation low and predictable (the Fed targets about 2% per year).
- Maximum employment — the highest level of employment the economy can sustain without sparking runaway inflation.
These two goals can pull in opposite directions, and managing that tension is the heart of what the Fed does.
Its main tool: interest rates
The Fed's primary lever is a short-term interest rate (the federal funds rate) that ripples out into the rates you pay on mortgages, car loans, and credit cards, and the rates you earn on savings (Federal Reserve — what is the federal funds rate / how monetary policy works).
- To cool an overheating economy or fight inflation, the Fed raises rates. Borrowing gets more expensive, spending and investment slow, and price pressure eases.
- To stimulate a weak economy, it lowers rates. Borrowing gets cheaper, spending and hiring pick up.
A crucial catch: these effects work with long and variable lags — a rate change can take many months to fully reach the real economy, so the Fed is always steering toward where the economy will be, not where it is.
Its other jobs
Beyond steering the economy, the Fed also:
- Supervises and regulates banks to keep the financial system safe and sound.
- Acts as the lender of last resort — providing emergency liquidity during panics so a crisis at one bank doesn't cascade through the whole system (Federal Reserve — what we do / financial stability).
- Operates the payment system that moves money between banks.
What the Fed is not
A common confusion: the Fed is not the U.S. Treasury. The Treasury collects taxes, issues government debt, and manages federal spending — that's fiscal policy, controlled by Congress and the President. The Fed handles monetary policy — the money supply and interest rates. Keeping these straight is the key to understanding most economic news: when you hear "the Fed raised rates," that's monetary policy; when you hear about deficits or stimulus checks, that's fiscal policy.
The bottom line
Think of the Fed as the economy's thermostat. It can't decide what the government spends, and it can't fix a supply shock — but by making money cheaper or more expensive, it nudges the whole economy toward stable prices and full employment, and stands ready to catch the financial system if it falls.
