The US Supreme Court's rejection of President Trump's tariff authority represents a significant setback for his aggressive trade policies, though US officials insist it won't derail existing deals with key partners. US Trade Representative Jamieson Greer stated on CBS's 'Face the Nation' that agreements with China, the European Union, Japan, and South Korea remain intact. However, the ruling complicates Trump's threat to impose a 15% tariff on all nations, which would significantly increase costs for UK businesses importing into the US.

Crawford Falconer, former UK chief trade negotiator, discussed these implications with Bloomberg Radio, highlighting the potential for the UK to face the largest tariff hike from its current reciprocal rate of 10%. This development forces businesses to reassess supply chains and pricing strategies amid heightened uncertainty.
