Dolar naik menjelang kesaksian Bernanke

MarketWatch (17/7) HONG KONG — The U.S. dollar edged up against some major currencies Wednesday, taking back some losses from the previous day, as investors awaited a congressional testimony from Federal Reserve Chairman Ben Bernanke.The ICE dollar index, which tracks the U.S. currency against six others, climbed to 82.679 from 82.599 late Tuesday in North America.The gains retraced some of the index’s losses Tuesday as investors placed bets on whether Fed Chairman Ben Bernanke would repeat his dovish tone from the previous week.Bernanke was due to testify before the House of Representatives later in the day, followed by an appearance before the Senate on Thursday in his twice-a-year report to the Congress.
