Trump Defies Supreme Court, Hikes Global Tariffs to 15% in Explosive Trade Move

President Donald Trump sent shockwaves through global markets this Saturday by announcing a unilateral hike in global tariffs from 10% to 15%. The move comes less than 24 hours after a U.S. Supreme Court ruling declared his previous tariff structure unconstitutional. In a fiery post on Truth Social, Trump blasted the court's decision as "ridiculous" and "anti-American," asserting his presidential authority to protect the nation from economic exploitation.

By raising tariffs to what he terms the "legally permissible level," Trump is effectively triggering a constitutional crisis between the Executive and Judicial branches. Economists warn that this 5% increase could lead to immediate price hikes for U.S. consumers and provoke massive retaliatory measures from global trade partners, further straining an already volatile international trade environment in 2026.
