Global stocks are sliding after President Trump’s new tariff announcement, with S&P 500 futures down nearly 1% and major indices worldwide falling. Analysts warn the true impact of these tariffs will hit the U.S. economy in the coming months through higher costs for companies and consumers. Import taxes are now at their highest since the 1930s.

Trump's new tariff rates include a 35% duty on many goods from Canada, which PM Mark Carney says he's "disappointed" about.

New U.S. tariffs are ready to take effect, targeting trade deficits with rates up to 41% and key country exemptions.
