Trump Raises Global Tariff to 15% Day After Supreme Court Strikes Down Tariff Policy

President Trump announced on Truth Social that he would increase his global tariff rate from 10% to 15%, effective immediately. This came less than 24 hours after the U.S. Supreme Court ruled that most of his sweeping tariff policy was illegal. In his post, Trump cited a 'thorough, detailed, and complete review of the ridiculous, poorly written, and extraordinarily anti-American decision on Tariffs issued yesterday' by the Supreme Court. The move represented a doubling down on his aggressive trade policy despite the judicial rebuke, with Trump defying the Court's ruling by imposing new tariffs at an even higher rate than those just struck down. The 15% tariff was implemented under Section 122 of the Trade Act of 1974, potentially facing similar legal vulnerabilities as the IEEPA-based tariffs the Court had just invalidated.
