The dollar fell against the euro and yen on Friday, erasing earlier gains after Federal Reserve Chairman Ben Bernanke said the central bank can do more to boost growth but offered no details on how it might act. But the greenback soared against the Swiss franc, hitting a one-month high above 0.8100 after Swiss bank UBS said it may charge fees on some franc deposits.
The euro was last up 0.6 percent at $1.4466, near a session peak, after having fallen as low as $1.4327 after Bernanke spoke. The dollar fell 1.1 percent to 76.60 yen on Friday. High-yield currencies also rallied against the greenback, with the Australian dollar up 1.4 percent at $1.0582. The euro shed 0.5 percent to 110.88 yen.
