Although what I have just described is, I believe, the most plausible outcome, macroeconomic projections are inherently uncertain, and the economy remains vulnerable to unexpected developments. The Federal Reserve is already supporting the economic recovery by maintaining an extraordinarily accommodative monetary policy, using multiple tools.
Should further action prove necessary, policy options are available to provide  8  BIS Review 110/2010  additional stimulus. Any deployment of these options requires a careful comparison of benefit and cost. However, the Committee will certainly use its tools as needed to maintain price stability – avoiding excessive inflation or further disinflation – and to promote the continuation of the economic recovery.
