In deciding not to start raising short-term interest rates, the Federal Open Market Committee (FOMC) said, “Recent global economic and financial developments may restrain economic activity somewhat and are likely to put further downward pressure on inflation in the near term.” As such, the Federal Reserve has chosen to see how the next few months transpire before opting to begin the process of normalizing rates, likely at the December 15–16 meeting, depending on the strength of incoming data between now and then.
