The Fed announced that it would reinstate a policy of 'quantitative easing' "initially at a pace of $45bn per month". It said it would keep its range of interest rates near zero as long as the unemployment rate remains above 6.5%, near-term inflation stays below 2.5% and longer-term inflation expectations continue to be well anchored.
