Known as the Fed, it`s America`s central bank. It`s led by Janet Yellen. Its job is to help stabilize America`s financial system.
The Fed makes moves to try to lower unemployment and control inflation, when the price of goods goes up too fast for people to afford them.
Because the U.S. economy is growing, the Fed raised its key interest rate by a quarter of a percentage point, not much. But gradual rate increases
are likely in the New Year.
