Trump Announces Increased Global Tariffs to 15% Following Supreme Court Ruling

President Donald Trump has announced plans to raise a new global tariff from 10% to 15%, just one day after the Supreme Court struck down his previous attempt at broad tariffs. The move comes as the administration seeks to reimpose trade levies on imported goods.

Supreme Court Ruling and Initial Tariffs

On Friday, February 20, 2026, the U.S. Supreme Court ruled that President Trump had overstepped his authority when he initially imposed sweeping global tariffs in 2025 . The court determined that Trump could not utilize the International Emergency Economic Powers Act (IEEPA) to levy taxes on imports from nearly every country worldwide. This ruling potentially opens the door for refunds to consumers and businesses for the approximately $130 billion generated by the original tariffs, a matter likely to be contested in further court proceedings.

New Tariffs Under the Trade Act of 1974

Hours after the Supreme Court’s decision, President Trump signed a proclamation invoking Section 122 of the Trade Act of 1974 to implement a 10% temporary tariff on goods from all countries. He subsequently announced via social media his intention to increase these tariffs to 15% .

Effective Date and Future Levies

Trump stated the new 15% tariffs would be “effective immediately” . However, it remains unclear whether official documentation detailing the timing has been signed. A White House fact sheet initially indicated the original 10% tariffs would take effect on Tuesday, February 24, at 12:01 a.m. ET. The White House has not yet responded to requests for clarification regarding the timing of the increased tariffs.

Trump also indicated that further tariff adjustments would be forthcoming, stating that his administration would “determine and issue the new and legally permissible Tariffs” in the coming months .
