How did global markets respond to Trump's tariff announcements on goods from Canada, Mexico, and China?

Markets reacted negatively before trading floors even opened. The Dow plummeted by 600 points (down 1.6%), matching declines in the S&P 500 and Nasdaq. Canada's Toronto Stock Exchange futures dropped 1.3%, while European markets like Germany's DAX fell nearly 2%. Despite initial panic, markets calmed slightly when trading began after news broke that Mexico and the US had reached a temporary one-month delay on tariffs. Meanwhile, Canada announced retaliatory measures, including 25% tariffs on $155 billion worth of American goods, starting with $30 billion immediately.
