President Donald Trump has escalated his response to a Supreme Court ruling by increasing global tariffs from an announced 10% to 15%. The Supreme Court, on Friday, February 20, 2026, declared a significant portion of Trump's previously imposed tariffs illegal, citing a lack of economic urgency justification by a six-to-three majority. In immediate reaction, Trump announced a 10% global tariff on Friday evening, expressing shame towards some court members. By Saturday, February 21, 2026, he further raised this to 15%, with the new decree set to take effect on February 24 for 150 days. France, through its Minister Delegate for Foreign Trade Nicolas Forissier, is advocating for a united European Union response, including potential retaliatory measures, and is in close contact with the European Commission. German Chancellor Friedrich Merz also called for a clear European stance ahead of his US visit.
