U.S. stock futures and the dollar were both sliding on Friday as Asian markets rallied after President Trump signaled he wouldn’t rush to raise tariffs on China. The moves came after Trump said he “would rather not” hike levies on imports from China, but added that the option to do so gives Washington “tremendous power” over Beijing. The president has yet to make any big moves on tariffs since he returned to the White House, although he has pledged to impose a 25% tax on goods from Canada and Mexico on Feb. 1.
