????Following the end of QE1, there was a 17% correction in stocks, leading the Fed to launch its second generation of the program. Then, after the wind-down of QE2, there was a 20% stock market correction, and the Fed once again chimed in with a third — and what they say will be final — round of QE.

????Some of that volatility happened in advance this time around, as evidenced by the fluctuations that rocked the markets over the past two weeks. A short-term correction and plunge in yields is fairly common, and could continue.

????The recent rocky markets haven’t yet worried the Fed, but if the market volatility becomes more severe the committee may decide to adjust its course, similar to its actions following QE1 and QE2.

????“That will be an interesting test for the Fed,” said Sonders. “Will they adjust monetary policy or their language given the volatility, even without a deterioration in their dual mandate?”
