It was, in his own words, “the best and most important trade deal ever.” Now President Donald Trump has refused to renew it. In a stunning reversal, Trump has decided not to renew the USMCA — the trade agreement between the United States, Mexico and Canada that he himself signed in 2018 — toppling a pillar of global trade stability. Here is what happened, and why the world is reeling from the decision.

The Stunning Reversal

The decision marks a dramatic about-face. Trump signed the USMCA — the United States-Mexico-Canada Agreement — in 2018, replacing the older NAFTA deal, and hailed it as a triumph. His refusal to renew it now represents a striking reversal of his own signature trade achievement, and a significant escalation of his protectionist trade agenda.

Trump called it “the best trade deal ever.” Now he’s letting it die. The whole of North American trade is holding its breath.

What Is the USMCA?

The USMCA governs trade between the three North American neighbours — the United States, Canada and Mexico. It covers everything from cars and agriculture to digital trade and labour standards. As one of the world’s largest trading relationships, the agreement has been a foundation of economic stability across the continent, giving businesses the certainty they need to invest and plan.

Why It Matters

The refusal to renew the USMCA injects enormous uncertainty into North American trade. Businesses that have built supply chains and made investments on the assumption of stable trade rules now face an uncertain future. The three economies are deeply integrated, and disruption to their trade relationship could raise prices, disrupt production and slow growth across the continent.

The Timing

The decision comes at a sensitive moment — even as the three nations co-host the 2026 World Cup, a symbol of North American cooperation. The contrast between the unity of the tournament and the friction of the trade decision is striking. It also comes amid Trump’s broader use of tariffs as a tool of economic policy, which has already been pushing trading partners like Europe and Brazil closer together.

The Global Ripple Effects

The consequences extend far beyond North America. The USMCA’s stability has been a pillar of the global trading system, and its unravelling adds to a broader picture of trade uncertainty. As the United States pursues an increasingly protectionist agenda, other nations are reassessing their trade relationships and seeking to reduce their dependence on the American market. The long-term effect could be a fundamental reshaping of global trade.
