The dollar hovered at one-week highs against the yen and held its ground on the euro early on Friday, having drifted up broadly after promising U.S. housing and factory activity data gave Treasury yields a bit of a lift.
The dollar index last traded at 80.228 after edging up 0.2 percent on Thursday. Against the yen, the greenback stood at 101.79, not far from the overnight high of 101.82 and well off a 3-1/2 month trough of 100.80 plumbed on Wednesday.
The euro eased to $1.3654 after suffering a 0.2 percent decline. It was within sight of a three-month low of $1.3634 set on Wednesday.
