Stocks slump, dollar soars as Trump tariffs trigger trade war fear

Asian stock markets slumped on Monday and US equity futures pointed sharply lower after US President Donald Trump’s tariffs on Canada, Mexico and China triggered fears of a broad trade war and hit to global growth.

The US dollar shot to a record peak against the Chinese yuan in offshore trading, and its highest against Canada’s currency since 2003 and the strongest against the Mexican peso since 2022.

Trump followed through with threats to slap Canada and Mexico with duties of 25% and China with a 10% levy at the weekend, calling them necessary to combat the flow of migrants and fentanyl into the US.

Canada and Mexico immediately vowed retaliatory measures, and China said it would challenge Trump’s levies at the World Trade Organization.

The tariffs, outlined in three executive orders, are due to take effect at 12:01 a.m. ET (0501 GMT) on Tuesday.

Trump’s move was the first strike in what could usher in a destructive global trade war and drive a surge in US inflation that would “come even faster and be larger than we initially expected,” said Paul Ashworth of Capital Economics.
