Accordingly, the Committee decided to continue purchasing additional agency mortgage-backed securities at a pace of $40 billion per month and longer-term Treasury securities at a pace of $45 billion per month. The Committee is maintaining its existing policy of reinvesting principal payments from its holdings of agency debt and agency mortgage-backed securities in agency mortgage-backed securities and of rolling over maturing Treasury securities at auction. Taken together, these actions should maintain downward pressure on longer-term interest rates, support mortgage markets, and help to make broader financial conditions more accommodative, which in turn should promote a stronger economic recovery and help to ensure that inflation, over time, is at the rate most consistent with the Committee’s dual mandate.

Hence the conundrum. On the one hand policy should cause lower rates, but it should also promote the higher rates of growth and inflation desired by the Fed, which in turn would trigger a ‘removal of accommodation’/rate hikes that much sooner than if the QE hadn’t been conducted.
