LONDON—The dollar was on track for its first weekly fall in four on Friday, as a hawkish rate hike from the European Central Bank lifted the euro and investors looked to U.S. inflation data early next week.
The dollar lost ground across the board, with the dollar index—which tracks the greenback against six major peers—falling as much as 1.1 percent on the day. It was last down 0.7 percent at 108.770 and is set for a 0.8 percent weekly fall.
