Overnight, Trump unveiled a 90-day pause on applying tariffs on every trading partner – excluding mainland China and Hong Kong – that was subject to his 10-per cent baseline levy. That announcement sent Wall Street on a tear, pushing the S&P500 Index to jump 9.5 per cent, while the Nasdaq Composite Index closed 12.2 per cent higher, the biggest one-day jump in 24 years.
Trump also unveiled additional levies on Chinese goods, pushing the total tariff on imports from China to 125 per cent. That came after Beijing raised its levy on all imports from the US to 84 per cent.
