The U.S. dollar is under pressure following a Supreme Court ruling that limited President Trump's emergency tariff powers, triggering a retaliatory 15% blanket tariff hike. Global markets are bracing for renewed trade volatility as the administration targets key industrial sectors with national security duties.
The U.S. Supreme Court has ruled that President Trump's use of emergency powers to levy broad tariffs was illegal, providing a temporary reprieve for trade partners. However, the administration immediately countered with a new 10% global tariff plan under the 1974 Trade Act, creating fresh uncertainty for Canadian exporters and CUSMA protections.
The U.S. Supreme Court ruled 6-3 that the International Emergency Economic Powers Act (IEEPA) does not authorize the President to impose tariffs, returning that power to Congress. This landmark decision invalidates 2025 trade measures and sets the stage for importers to reclaim billions of dollars in duties.
The U.S. Supreme Court has invalidated President Trump's use of the 1977 International Emergency Economic Powers Act to impose broad global tariffs, ruling 6-3 that such authority rests with Congress. This decision significantly restricts the executive branch's ability to bypass legislative oversight for trade policy under the guise of national emergencies.
