Trump Escalates Global Tariffs to 15% After Court
Donald Trump announced a 15% global tariff effective immediately on Saturday via Truth Social, escalating from the 10% levy he imposed Friday after the Supreme Court struck down his reciprocal tariff policy. Trump claimed the higher rate was “fully allowed, and legally tested,” attacking the court’s decision as “ridiculous, poorly written, and extraordinarily anti-American” while asserting countries have been “ripping off” the United States for decades.
The British Chambers of Commerce condemned the increase as damaging to UK businesses, warning that the additional 5% tariff on most British exports would harm trade, US consumers, and global economic growth. William Bain, head of trade policy at the BCC, stated the announcement proved their fears that Trump’s backup plan would be worse than his initial proposal and called for businesses to receive “clarity and certainty” rather than escalating tariffs.
Britain had negotiated the lowest initial rate of 10% under a deal between Prime Minister Sir Keir Starmer and Trump, with carve-outs protecting steel, automobiles, and pharmaceuticals. The UK government indicated it expected these preferential arrangements to remain intact under the new 15% framework, though officials acknowledged uncertainty about the tariff’s full implications for British trade.
Trump bypassed Congress by signing an executive order Friday invoking emergency powers after the Supreme Court overturned his reciprocal tariffs policy, allowing him to unilaterally increase import taxes. His escalation to 15% followed his public attacks on Supreme Court justices as “unpatriotic and disloyal” for blocking his previous tariff authority.
