Supreme Court Trump Tariffs Voided 6–3; 15% Reset Feb 2026

The Supreme Court struck down President Donald Trump’s IEEPA-based tariffs in a 6–3 decision on Feb. 20, 2026, ruling the president lacked statutory authority to impose those duties. The ruling hit Washington immediately, with Trump pivoting to a temporary import surcharge under Section 122 of the Trade Act of 1974, while markets whipsawed and Bitcoin briefly jumped before fading.

Context

The Court framed the question narrowly: whether the International Emergency Economic Powers Act (IEEPA) authorizes the president to impose tariffs. It ruled the statute does not, rejecting the administration’s attempt to read tariff power into IEEPA’s language about “regulat[ing] … importation.”

The decision resolved two linked disputes, Learning Resources, Inc. v. Trump and Trump v. V.O.S. Selections, both challenging tariffs the administration imposed by declaring national emergencies and invoking IEEPA. SCOTUSblog reported the Court affirmed the lower-court judgment in Trump v. V.O.S. Selections and vacated and remanded Learning Resources for dismissal on jurisdictional grounds, while keeping the merits holding unqualified.

Details

Chief Justice John Roberts wrote the principal opinion, and six justices joined the core statutory holding that IEEPA is “not a tariff statute.” Justices Sonia Sotomayor, Elena Kagan, Neil Gorsuch, Amy Coney Barrett, and Ketanji Brown Jackson joined those sections, according to SCOTUSblog’s breakdown of the opinion structure.

Two dissents followed: Justice Clarence Thomas dissented separately, and Justice Brett Kavanaugh dissented in an opinion joined by Thomas and Justice Samuel Alito. SCOTUSblog described additional concurrences and partial concurrences that narrowed which parts of the reasoning carried a full majority.

Roberts’ opinion emphasized the breadth of the power the administration claimed. “The President asserts the extraordinary power to unilaterally impose tariffs of unlimited amount, duration, and scope,” Roberts wrote, before concluding IEEPA’s grant of authority falls short.

Impact

Penn Wharton estimated businesses could be owed more than $175 billion in refunds tied to the struck-down IEEPA tariffs, a figure Reuters highlighted as potentially flowing back to the private sector. CNBC also reported refunds could top $175 billion, pointing to the scale of duties collected under the invalidated program.

“IEEPA-related tariffs deemed illegal account for roughly 60% of the tariffs to date. That’s a significant issue. Until President Trump substitutes those tariffs with other authorities, the tariff rate has effectively decreased from approximately 9.5% to about 5%.” – Brian LeBlanc, Senior Economist, PNC Financial Services Group, Feb. 20, 2026.

Yale’s Budget Lab measured the effective U.S. tariff rate at 16.0% pre-ruling, dropping to 9.1% after the IEEPA tariffs were struck down, then rising to 13.7% after Trump increased the Section 122 surcharge to 15%. In the scenario where Section 122 expires on schedule, the group estimated average household costs of $600–$800 per year.

Bitcoin reacted intraday: Yahoo Finance described a post-ruling lift, while crypto press noted a quick reversal later in the same session. Reported snapshots put BTC around $66,900 near the ruling time and nearer $67,800–$68,000 at the intraday high, with variation reflecting timing (peak vs. later prints).

Next Steps

Trump moved within hours to a replacement tool: Section 122 of the Trade Act of 1974, which Axios and CFR described as capped at 15% and limited to 150 days unless Congress votes to extend. Politico reported Trump first set the surcharge at 10% and then raised it to the 15% maximum on Feb. 21.

That clock puts the key policy deadline around July 19–20, 2026 (150 days after Feb. 20) unless lawmakers approve an extension. Separately, Yale’s Budget Lab noted “substantial uncertainty” about how and when refunds will be administered, keeping cash-flow timing as the next major operational unknown for importers and markets.
