Trump threatens Mexico and Canada

Donald Trump sent shockwaves through North American trade channels on 25 November by threatening to impose an immediate twenty-five per cent tariff on all imports from Mexico and Canada on day one of his presidency, linking the measure to border enforcement and illicit drug flows. The threat struck directly at the heart of the deeply integrated USMCA free trade architecture.

Unlike trade with China, trade across North America is defined by deeply integrated supply chains, particularly in automotive manufacturing, energy, and agriculture, where components cross the border multiple times before final assembly. A twenty-five per cent tariff on Canada and Mexico would disrupt North American auto assembly lines, spike retail gasoline prices in the Midwest, and shatter corporate margin structures across the continent.

Threatening twenty-five per cent tariffs on Mexico and Canada weaponises trade against America’s closest neighbours, threatening to sever the integrated supply chains of North American industry.
