With the economy now evidently in a period of transition, monetary policy must be conducted with great care and with close attention to the evolution of the economic outlook as implied by incoming information. Given recent developments, the medium-term outlook for inflation will receive particular scrutiny. There is a strong consensus among the members of the Federal Open Market Committee that maintaining low and stable inflation is essential for achieving both parts of the dual mandate assigned to the Federal Reserve by Congress...Therefore the Committee will be vigilant to ensure that the recent pattern of elevated monthly core inflation readings is not sustained. Toward this end, and taking full account of the lags with which monetary policy affects the economy, the Committee will seek a trajectory for the economy that aligns economic activity with underlying productive capacity. Achieving this balance will foster sustainable growth and help to forestall one potential source of inflation pressure. In addition, the Committee must continue to resist any tendency for increases in energy and commodity prices to become permanently embedded in core inflation.
