The Fed meets eight times a year to assess the health of the US economy and vote on the federal funds rate, the rate banks use to lend and borrow money. While the Fed’s decision to change rates doesn’t directly affect savings rates, changes in APYs typically follow. The changes can take several weeks or even months to take effect.

In the end, the Fed decided to go big. The Federal Reserve lowered its key interest rate by a hefty half percentage point Wednesday, moving ahead with its first rate cut in four years and cheering markets that expected an emphatic move amid a softening jobs picture.
