Thirty-Three Hour Race May Induce ECB Surrender

Federal Reserve Chairman Ben S. Bernanke’s push to jump-start the U.S. economy this week may weaken the dollar, forcing at least one other central bank to add its own stimulus to offset a rising exchange rate.

Bernanke is set to embark on an unprecedented second round of unconventional monetary easing, one result of which may be a cheaper dollar that boosts U.S. growth by helping American exports. A related consequence: stronger currencies abroad, threatening European and Japanese expansion.
