The dollar erased losses against most major currencies on Thursday after Federal Reserve Chairman Ben Bernanke doused mounting market speculation that another round of monetary easing was on the way. The euro, which had been trading near $1.4225, shed its gains on Bernanke's remarks and was last down 0.2 percent at $1.4160.
Bernanke's comment also helped the dollar climb a bit more off a record low against the Swiss franc and a four-month low against the yen. Both the euro and dollar hit record lows against the Swiss currency on Thursday. The rush for safer assets also boosted the yen, with the dollar hitting a four-month low around 78.45 yen before rebounding to 79.25, up 0.3 percent.
