In terms of the overall impact on Donald Trump's tariff agenda, the consultancy Capital Economics estimates the court ruling would reduce the US's average external tariff this year from 15% to 6.5%. This would still be a considerable increase on the 2.5% level of 2024 and would be the highest since 1970.

The CIT ruled the Executive Orders enacting the tariffs are declared to be invalid as they exceed the authority of the president to regulate importation by means of tariffs.

A federal court has dealt a setback to President Donald Trump's campaign of imposing tariffs on trading partners, but the trade wars are far from over, administration officials and trade experts said Thursday.
