The dollar rose on Wednesday after a report showed U.S. producer prices rebounded in August and as traders turned their focus to consumer inflation data due on Thursday that will be closely watched by the U.S. Federal Reserve as it considers when to next raise interest rates.
The dollar index, which tracks the currency against a basket of six major rivals, was up 0.6 percent at 92.435, after rising to 92.53, its highest in more than a week.
The index, which fell to its lowest since January 2015 last week, on worries linked to Hurricane Irma and North Korea, has climbed this week as risk sentiment improved.
The index added to this week's gains on Wednesday after the U.S. Labor Department said its producer price index for final demand increased 0.2 percent in August after slipping 0.1 percent in July.
While domestic producer prices rose less than forecast, "the rebound does suggest that the U.S. economy retains underlying momentum," said Karl Schamotta, director of global market strategy at Cambridge Global Payments in Toronto.
