US President Donald Trump has raised the global duty on imports into the United States to 15 percent, pressing ahead with his aggressive tariff policy barely a day after the Supreme Court curtailed much of his earlier trade measures.
Posting on his Truth Social platform, Donald Trump said the administration reviewed what he described as an “anti-American” court decision and opted to move tariffs to what he called a fully permitted legal ceiling.
Moments earlier, the Supreme Court of the United States ruled by a 6–3 majority that the president overstepped his authority by imposing sweeping duties under a 1977 emergency economic statute, forcing the White House to pivot to an alternative legal route.
In an unusually sharp reaction, Trump criticised conservative justices who sided with the majority, accusing them of disloyalty while defending the three dissenting judges for what he called their firmness.
Analysts say the judgment represents one of the most significant judicial setbacks to Trump’s economic agenda since his return to office, disrupting a tariff strategy that has unsettled global trade flows.
Global reaction has been swift, with Luiz Inacio Lula da Silva urging Washington to treat nations equally, while Friedrich Merz signalled consultations with European partners ahead of planned talks in the United States.
Domestic critics also weighed in, as Josh Shapiro called on the president to respect the ruling and halt policies he said were hurting American businesses and families.
White House officials clarified that the new tariff authority is temporary and valid for up to 150 days, with exemptions maintained for sectors already under separate trade investigations.
Despite the ruling, earlier industry-specific duties on steel, aluminium and other goods remain intact, and ongoing government probes could trigger additional targeted tariffs.
Financial markets reacted cautiously, with Wall Street recording modest gains as investors assessed the legal and economic implications of the decision and Trump’s latest move.
Business groups welcomed the judgment for bringing clarity, though uncertainty lingers over possible refunds for previously collected duties — a matter Trump said could face prolonged legal battles.
