The speech was made last night during the Asian trading time zone and resulted in a reversal of the lower dollar trend. Some traders used it as an excuse to take profit on their short positions. Bernanke said that he was prepared to implement exit strategies and tighten monetary policy but now is not the time as he does not see sufficient evidence yet in the economic recovery for them to be implemented. He gave no indication on timing or the pace of the exit strategy but it will be when the time is right and when he sees stronger evidence of the economic recovery.
