US Trade Court Rejects Trump's 10% Global Tariff Proposal

Summary

On May 7, 2026, the US Court of International Trade ruled 2-1 that the Trump administration’s 10% global import tariff proposal lacked a legal basis under Section 122 of the Trade Act of 1974 []. This follows a previous Supreme Court ruling in February that also struck down tariff measures under the International Emergency Economic Powers Act []. The court has issued a permanent injunction against these tariffs for specific plaintiffs, though broader litigation continues [].

Impact Analysis

So, the courts are basically putting a leash on the ‘Tariff 2.0’ playbook. This 10% global levy was supposed to be the administration’s big hammer, but the Trade Court just confirmed it has no legal legs []. This is the second major judicial slap-down in months—remember the Supreme Court’s ruling in February? [] It’s a clear signal: unilateral trade wars are becoming much harder to execute without explicit Congressional buy-in.

For the portfolio, this is a massive relief valve for global supply chains and the EU auto sector, which was bracing for even steeper 25% hikes [businessinsider]. The market has been pricing in a heavy ‘chaos premium,’ and this ruling effectively deflates that tail risk. I’d be looking at undervalued non-US manufacturing and EM exporters that were beaten down on trade fears. The ‘unpredictability’ factor just got a reality check. Bottom line: the executive branch doesn’t have a blank check on trade, which should stabilize sentiment across Asian and European indices in the near term.
