Dollar risk not 'worrisome' says Bernanke

Federal Reserve chairman Ben Bernanke said in a 21 March letter that a possible decline in the dollar because of less foreign investment wouldn't have a "worrisome" effect on the U.S. economy.

Bernanke said it isn't clear that faster economic growth in emerging markets would cause investors to shift capital to those countries and away from the U.S. Should that happen, ``it might be associated with a decline in the value of the dollar and a narrowing of the U.S. trade deficit,'' Bernanke wrote
