Live, rolling coverage of business, economics and financial markets as US president said he would impose first tariffs of new administration on 1 February

Donald Trump’s White House will invoke emergency powers to introduce tariffs on Canada and Mexico, Reuters reports:

Two sources familiar with the matter said that Trump was expected to invoke the International Emergency Economic Powers Act (IEEPA) as the legal basis for the tariffs, declaring a national emergency over fentanyl overdoses that killed nearly 75,000 Americans in 2023 and illegal immigration.

The statute enacted in 1977 and modified after the 9/11 attacks in 2001 gives the president broad powers to impose economic sanctions in a crisis.
