Following a legal setback from the Supreme Court, U.S. President Donald Trump has escalated his tariff policy, increasing global tariffs from 10% to 15%. Trump announced this decision on his platform Truth Social on Saturday, February 22, 2026, after the Supreme Court prohibited him from imposing tariffs based on a 1977 emergency law, deeming he had overstepped his authority. Undeterred, Trump is now invoking a 1974 trade law, which permits tariffs up to 15% for a maximum of 150 days, a limit he is fully utilizing. This move, described by Trump as a response to a "ridiculous, anti-American decision," has generated international concern, prompting the EU Parliament to schedule an emergency session and German Chancellor Friedrich Merz to plan a trip to Washington to discuss the policy. Experts anticipate global trade disruption, with the University of Pennsylvania estimating potential claims for repaid tariffs could cost the U.S. budget $175 billion.
