In response to President Trump's sweeping announcement of new tariffs, U.S. stocks endured a historic plunge, with the Dow Jones dropping 1,679 points, the largest drop since COVID. Major companies such as Nike, Apple, and Amazon saw significant losses, fearing heightened costs for imported goods and potential recessions. Trump claimed the tariffs would restore U.S. manufacturing but elicited retaliatory threats from foreign leaders. Economists believe these tariffs may worsen inflation, hinder economic growth, and lead consumers to cut spending. Despite concerns, Trump remains confident about economic outcomes following the tariffs.
