The Federal Reserve (sometimes called "The Fed") is a large central bank in Washington, D.C. that was founded in 1913. It lends money to other, smaller banks. The "Federal Reserve Board" is a group of financial leaders who work for the Federal Reserve and decide how much to charge these banks for borrowing money (this charge is called an "interest rate"). The Federal Reserve interest rate is decided by the Federal Reserve Board after studying the condition of the US economy.
