Donald Trump’s recent tariffs roiled global markets, pushing the U.S. dollar up by 1.4% and sending global equities lower. The Canadian dollar, the euro, and the Mexican peso weakened significantly while U.S. stock futures declined. U.S. Treasury yields rose as investors reassessed trade war risks. Economists and analysts warn the tariffs could slow global growth, spur inflation, and lead to prolonged economic pain. Major banks predict a potential halving of U.S. GDP growth if the measures persist.
