BMW shares fell Tuesday after the U.S. announced a major tariff hike on Canadian automotive imports.

The U.S. will raise tariffs on Canadian-made vehicles and parts from 25% to 50%. This new rate takes effect on January 1, 2027.

Investors expressed concern over BMW’s extensive North American operations and cross-border supply chains. The market is assessing how higher costs will impact vehicle pricing and U.S. sales.

Trade policy uncertainty has triggered broader caution for BMW and other international manufacturers.
