Financial markets around the world are reeling Thursday following President Donald Trump’s latest and most severe volley of tariffs, and the U.S. stock market may be taking the worst of it. The S&P 500 was down 4% in morning trading, worse than the drops for other major stock markets. The Dow Jones Industrial Average was down 1,520 points, or 3.6%, as of 10:10 a.m. Eastern time, and the Nasdaq composite was 4.0% lower. Little was spared as fear flared globally about the potentially toxic mix of higher inflation and weakening economic growth that tariffs can create. Everything from crude oil to Big Tech stocks to the value of the U.S. dollar against other currencies fell. Even gold, which has hit records recently as investors sought something safer to own, pulled lower. Some of the worst hits walloped smaller U.S. companies, and the Russell 2000 index of smaller stocks dropped more than 5% into what’s called a “bear market” after losing more than 20% from its record. Investors worldwide knew Trump was going to announce a sweeping set of tariffs late Wednesday, and fears surrounding it had already pulled the S&P 500 10% below its all-time high last month. But Trump still managed to surprise them with “the worst case scenario for tariffs,” according to Mary Ann Bartels, chief investment officer at Sanctuary Wealth. Trump announced a minimum tariff of 10% on imports, with the tax rate running much higher on products from certain countries like China and those from the European Union. It’s “plausible” the tariffs altogether, which would rival levels unseen in roughly a century, could knock down U.S. economic growth by 2 percentage points this year and raise inflation close to 5%, according to UBS.
