The central, resolved development in US tariff policy as of mid-2026 is a Supreme Court ruling on presidential tariff authority.

Supreme Court strikes down IEEPA tariffs (Feb 20, 2026). In the consolidated cases Learning Resources, Inc. v. Trump (No. 24-1287) and Trump v. V.O.S. Selections, Inc. (No. 25-250), the Court held 6-3 that the International Emergency Economic Powers Act (IEEPA) does not authorize the President to impose tariffs. Chief Justice Roberts wrote the majority (joined by Sotomayor, Kagan, Gorsuch, Barrett, and Jackson); Justices Thomas, Kavanaugh, and Alito dissented. (The major-questions portion of the reasoning was a narrower three-justice plurality of Roberts, Gorsuch, and Barrett.)

  • Reasoning: IEEPA's authority to "regulate … importation" does not include the power to levy tariffs/duties; tariffs operate directly on domestic importers to raise revenue for the Treasury, and the tariff power is "a branch of the taxing power" reserved to Congress under Article I, so such an extraordinary delegation must be clear (major-questions doctrine).
  • Tariffs invalidated: (1) the April 2025 "Liberation Day"/"reciprocal" tariffs (a 10% baseline plus higher country-specific rates) and (2) the "trafficking" tariffs on China, Canada, and Mexico (justified on fentanyl/immigration grounds).
  • Procedural posture: The decision affirmed the en banc Federal Circuit's August 2025 ruling (which had called the tariffs "unbounded in scope, amount, and duration") and the Court of International Trade.
  • Refunds: The Court did not decide whether the IEEPA tariffs already collected — on the order of $166 billion (CBP's refund figure, from over 330,000 importers) to roughly $175–179 billion (Penn-Wharton estimate) — must be refunded; that issue was left to further litigation, and over 2,000 recovery suits had been filed by late February.

Subsequent enacted action. Within hours of the ruling, President Trump issued a proclamation under Section 122 of the Trade Act of 1974, imposing a 10% global tariff (effective Feb 24, 2026) to address a balance-of-payments concern; on Feb 21 he announced an intention to raise the rate toward the statutory 15% cap. Because Section 122 authority is limited to 150 days, the surcharge is set to expire July 24, 2026.

(Analysis of how these developments "might affect global trade" is forward-looking and outside the scope of verifiable, resolved fact.)
