Trump tariffs live updates: Supreme Court will not rule on Trump's most sweeping duties Friday

Key Points

  • Supreme Court Ruling Imminent: The US Supreme Court is set to rule on the legality of President Trump's sweeping tariffs, a decision that could impact his authority to impose global duties on trade partners, with a potential announcement as early as Friday.**
  • Tariff Rates at Historic Highs: US tariff rates have surged to an average of 15-16.8% by the end of 2025, the highest in at least 80 years, reflecting Trump's protectionist policies, with experts predicting little change in 2026.**
  • Legal and Economic Implications: A ruling against Trump's tariffs could lead to significant refunds for companies like Costco, though Trump and his administration are prepared to explore alternative authorities if the court rejects the use of the 1977 International Emergency Economic Powers Act.**
  • Global and Domestic Reactions: Trump's tariffs have sparked global debate and increased complexity for US importers, while the president insists they strengthen national and financial security, despite skepticism from both conservative and liberal justices.**
  • Business Uncertainty: Importers face heightened uncertainty and complexity, with the US tariff book expanding to over 4,500 pages in 2026, and companies bracing for a potential $150 billion refund fight if the tariffs are struck down.**

Summary

President Trump's expansive tariffs, which have driven US tariff rates to historic highs of 15-16.8% by the end of 2025, face a critical test as the Supreme Court prepares to rule on their legality, potentially as soon as Friday. Invoking a 1977 law for national emergencies, Trump's policies have sparked global debate and lawsuits from companies like Costco seeking refunds on import duties. Despite skepticism from both conservative and liberal justices during November arguments, Trump remains defiant, asserting tariffs bolster national and financial security. Experts predict tariff rates will remain steady into 2026, reflecting entrenched American protectionism, even as importers grapple with increased complexity and a tariff book exceeding 4,500 pages. A ruling against Trump could trigger a $150 billion refund battle, though the administration hints at alternative measures to sustain its trade stance. The decision's outcome will likely have far-reaching implications for US trade policy and global economic relations.
