US president-elect Donald Trump has announced plans to impose tariffs on goods from Canada, Mexico, and China, with effect from January 20, 2025. A 25% tariff will be applied to Canadian and Mexican imports to address drug imports and migration issues, while China will face a 10% additional tariff. These measures have negatively affected stock market values, particularly in Canada with a significant drop in rapeseed and fertilizer prices. The proposed tariffs could also lead to a shift in the US potash fertilizer market, making Russia a more dominant supplier.
