The U.S. dollar eased broadly on Wednesday after Singapore revalued its currency and as upbeat earnings from technology bellwether Intel Corp boosted appetite for riskier currencies.

Singapore's central bank re-centered its trade-weighted band to the prevailing exchange rate level, which was in the upper half of the previous band. >>
