In a speech at the Economic Club of New York, Federal Reserve Vice Chair Stanley Fischer said aging demographics, a factor out of the Fed's control, is one of the reasons for the central bank's slow pace of rate increases.

"One recent study by Federal Reserve economists suggests that population aging -- through its effects on saving -- could be pushing down the longer-run equilibrium federal funds rate relative to its level in the 1980s by as much as 75 basis points," Fischer said in his speech.

He also said, "I am sure that the reaction of many of you may be, 'Well, if you and your Fed colleagues dislike low interest rates, why not just go ahead and raise them? You are the Federal Reserve, after all.' One of my goals today is to convince you that it is not that simple, and that changes in factors over which the Federal Reserve has little influence -- such as technological innovation and demographics -- are important factors contributing to both short- and long-term interest rates being so low at present."
