The dollar turned in its best weekly performance in more than four months as President Donald Trump’s latest tariff threats heightened concern that escalating trade tensions will stoke inflation and derail a rally in risk markets.
The Bloomberg Dollar Spot Index rose 0.73% this week, the best showing — by a hair — since the week of Feb. 28, after falling for two weeks before that. The Japanese yen, British pound were among the worst performers in the Group of 10 this week.
