US Shifts Trade War to Lock In Allies With 50% Tariff Threats
2 articles · Updated · Financial Times · Jul 24
Summary
Washington is moving beyond raising tariffs to punishing countries that build alternatives to US finance, tech and defense networks, using market access and services as leverage.
The strategy aims to make the US harder to coerce economically and extract more value from its superpower assets; foreign income from finance, tech, IP and defense has risen to 7% of GDP.
Recent pressure points include a threatened 50% levy on Canada, a 25% tariff on Brazil after Pix gained traction, and temporary June limits on foreigners using Anthropic’s AI models.
Allies are still trying to preserve US access while funding substitutes in payments, air defense and digital infrastructure, a shift that has already cost some US firms business in Europe.
Europe and Asia have rival projects due within five years, raising the prospect that Washington’s next escalation could target the use of alternatives rather than tariffs alone.
Is the U.S. using tariffs, AI access and defense ties to stop allies from building alternatives to American power?
Why are countries from Canada to Europe accelerating payment, defense and AI substitutes as Washington tightens access to its networks?
The 2026 U.S.-Canada Trade War: Trump’s 50% Tariff Shock, Legal Battles, Economic Fallout, and Canada’s Global Pivot
Overview
In July 2026, President Trump imposed a sweeping 50 percent tariff on Canadian imports, triggering a chain reaction that disrupted North American supply chains and forced manufacturers to abandon efficient 'just-in-time' operations for costly 'just-in-case' strategies. This move followed a Supreme Court ruling that blocked the use of emergency powers for tariffs, leading the administration to use an old trade law instead. The tariffs caused immediate price hikes for consumers and spurred Canadian provinces to quickly liberalize internal trade. Globally, the U.S. expanded tariffs to over 80 countries, shaking financial markets and prompting Canada to accelerate trade diversification, especially toward Asia and India.
