SCOTUS Blocks Trump Tariffs, New 10% Global Levy Announced
Legal limits met swift executive response in Washington’s trade battle
The U.S. Supreme Court ruled 6–3 that President Donald Trump’s tariffs imposed under the International Emergency Economic Powers Act were illegal, striking down a core pillar of his trade agenda. The decision raises the possibility that the government could owe up to $175B in refunds to importers for previously collected duties, though the Court did not explicitly address repayment.
Within hours, Trump announced a new 10% “global tariff” under Section 122 of the Trade Act of 1974, which allows duties for up to 150 days without congressional approval. He also confirmed that tariffs under Sections 232 and 301 remain in effect and signaled new investigations that could lead to more permanent measures.
Economists estimate the invalidated tariffs represented roughly 60% of current duties, implying a temporary drop in the effective tariff rate before replacement actions.
Markets remained steady, with the S&P 500 rising 0.7% as investors anticipated alternative policy tools.
