QE4 to continue

Today, the Fed announced that they will continue to buy $85 billion worth of securities per month "until the outlook for the labor market has improved substantially in the context of price stability."

This is a change of plans for the Fed.  This summer, they announced that they had planned to taper (decrease) these purchases as the unemployment rate fell.  What changed their mind? Low inflation and high unemployment:

Some indicators of labor market conditions have shown further improvement in recent months, but the unemployment rate remains elevated. Household spending and business fixed investment advanced, and the housing sector has been strengthening, but mortgage rates have risen further and fiscal policy is restraining economic growth. Apart from fluctuations due to changes in energy prices, inflation has been running below the Committee's longer-run objective, but longer-term inflation expectations have remained stable.

So the taper is off, but tapirs are still on.
