On August 27, 2010 in a much Ballyhooed Speech at Jackson Hole, Bernanke said
The Committee is prepared to provide additional monetary accommodation through unconventional measures if it proves necessary, especially if the outlook were to deteriorate significantly.
The issue at this stage is not whether we have the tools to help support economic activity and guard against disinflation. We do. As I will discuss next, the issue is instead whether, at any given juncture, the benefits of each tool, in terms of additional stimulus, outweigh the associated costs or risks of using the tool.
The FOMC will strongly resist deviations from price stability in the downward direction. Falling into deflation is not a significant risk for the United States at this time, but that is true in part because the public understands that the Federal Reserve will be vigilant and proactive in addressing significant further disinflation. It is worthwhile to note that, if deflation risks were to increase, the benefit-cost tradeoffs of some of our policy tools could become significantly more favorable.
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 additional stimulus. Any deployment of these options requires a careful comparison of benefit and cost.
Really?!
In light of yesterday's FOMC Statement inquiring minds are asking four key questions.
1. Did the economic conditions "deteriorate significantly"?
2. Is deflation a significant risk?
3. Does the Fed "have the tools"?
4. Did the Fed do a "careful comparison of benefit and cost" for further quantitative easing?
