  • Fed economists say low interest rates have only a "modest" link to asset prices like stocks.
  • That runs contrary to Wall Street thinking that central bank policy has fueled much of the bull market.
  • Every time the Fed has tried to tighten policy, the markets have recoiled and the Fed has relented.

The Federal Reserve's extraordinary policy moves over the last 12 years have marched arm-in-arm with the biggest bull market in Wall Street history.

But the central bank's economists say the two really have little in common.
