I emphasize that, because our asset purchases depend on economic and financial developments, they are by no means on a preset course. On the one hand, if economic conditions were to improve faster than expected, and inflation appeared to be rising decisively back toward our objective, the pace of asset purchases could be reduced somewhat more quickly. On the other hand, if the outlook for employment were to become relatively less favorable, if inflation did not appear to be moving back toward 2 percent, or if financial conditions--which have tightened recently--were judged to be insufficiently accommodative to allow us to attain our mandated objectives, the current pace of purchases could be maintained for longer. Indeed, if needed, the Committee would be prepared to employ all of its tools, including an increase the pace of purchases for a time, to promote a return to maximum employment in a context of price stability.
As I noted, the second to...ol the Committee is using to support the recovery is forward guidance regarding the path of the federal funds rate. The Committee has said it intends to maintain a high degree of monetary accommodation for a considerable time after the asset purchase program ends and the economic recovery strengthens. In particular, the Committee anticipates that its current exceptionally low target range for the federal funds rate will be appropriate at least as long as the unemployment rate remains above 6-1/2 percent and inflation and inflation expectations remain well behaved in the sense described in the FOMC's statement.
As I have observed on several occasions, the phrase "at least as long as" is a key component of the policy rate guidance. These words indicate that the specific numbers for unemployment and inflation in the guidance are thresholds, not triggers. Reaching one of the thresholds would not automatically result in an increase in the federal funds rate target; rather, it would lead the Committee to consider whether the outlook for the labor market, inflation, and the broader economy justified such an increase. For example, if a substantial part of the reductions in measured unemployment were judged to reflect cyclical declines in labor force participation rather than gains in employment, the Committee would be unlikely to view a decline in unemployment to 6-1/2 percent as a sufficient reason to raise its target for the federal funds rate. Likewise, the Committee would be unlikely to raise the funds rate if inflation remained persistently below our longer-run objective. Moreover, so long as the economy remains short of maximum employment, inflation remains near our longer-run objective, and inflation expectations remain well anchored, increases in the target for the federal funds rate, once they begin, are likely to be gradual.
