The Federal Reserve (or Fed) is the Central Bank of the United States. Its duties include conducting monetary policy, regulating banks, maintaining financial stability, and conducting banking services for other banks and for the US government. Some of the Fed’s important roles include setting interest rates and buying and selling US bonds to control the money supply. The Fed has a double mandate to control inflation and unemployment. During the Great Recession, the Federal Reserve expanded its traditional role in order to stabilize the financial industry, using unconventional methods such as Quantitative Easing.
