President Donald Trump’s doubling of tariffs on foreign steel and aluminum could hit Americans in an unexpected place: grocery aisles. “Rising grocery prices would be part of the ripple effects,” says Usha Haley, an expert on trade and professor at Wichita State University, who added that the tariffs could raise costs across industries and further strain ties with allies “without aiding a long-term U.S. manufacturing revival.” Trump’s return to the White House has come with an unrivaled barrage of tariffs, with levies threatened, added and, often, taken away, in such a whiplash-inducing frenzy it’s hard to keep up.
