President Donald Trump has announced a 15% global tariff on imports to the United States, escalating his trade policy shortly after a major Supreme Court setback. On February 20, 2026, the U.S. Supreme Court ruled 6-3 that Trump exceeded his authority by imposing sweeping “reciprocal” and other tariffs under the International Emergency Economic Powers Act (IEEPA).
The Court held that IEEPA—intended for national emergencies involving foreign threats—does not authorize the president to unilaterally impose tariffs, as the power to tax belongs to Congress. This invalidated much of Trump’s prior broad tariff program (including so-called “Liberation Day” measures), leading the administration to stop collecting those duties and potentially opening the door to refunds for importers.
In response, Trump quickly pivoted: He invoked Section 122 of the Trade Act of 1974; a rarely used provision allowing temporary import surcharges up to 15% for 150 days to address international payments issues or trade deficits to impose a new 10% global tariff on most imports, effective from Tuesday, February 24.
On Saturday (February 21), he raised it to the maximum 15% via Truth Social post, calling it “effective immediately” after reviewing the ruling, which he criticized as “ridiculous” and “anti-American.” Trump has suggested this provides “legal certainty” for even stronger future actions and that other tariff authorities remain available.

His trade representative has described the new approach as “roughly equivalent” to prior levels. The move has sparked significant backlash and uncertainty, particularly in Europe. The European Union is halting or freezing progress on a U.S.-EU trade deal agreed in 2025 which involved aspects like 15% tariffs on many EU exports to the U.S. in exchange for concessions.
EU lawmakers and the European Parliament’s trade committee plan to suspend ratification and demand clarity and commitments from the U.S. amid “pure tariff chaos.” Officials warn the new tariffs risk undermining transatlantic trade agreements, with calls for the U.S. to honor prior deals.
Similar concerns from the UK, though its spokesman indicated the new tariff may not heavily impact their separate economic arrangement with the U.S. Other partners like those with existing deals suc as Japan, and South Korea may face exemptions or questions on applicability. U.S. futures dipped; the dollar weakened, gold rose as a safe haven, and oil eased slightly amid unrelated U.S.-Iran talks.
Agriculture groups called for carveouts to protect inputs, while businesses face uncertainty over supply chains, inflation, and potential retaliation. The 15% rate is temporary unless extended by Congress, but it signals Trump’s determination to pursue aggressive trade measures despite legal hurdles. This rapid sequence has heightened global trade tensions, with experts noting ongoing “tariff roulette” and risks to economic stability.
Analyses from sources like the Yale Budget Lab estimate the current tariff regime including this new levy and remaining prior duties could raise consumer prices by about 0.6% in the short run, equivalent to a roughly $600–800 annual loss per average household in purchasing power.
If made permanent, this rises to 0.8–1.0% price impact and $1,000–1,300 per household. Macro effects include a potential 0.3 percentage point increase in unemployment by end-2026. Fiscal revenue: Around $1.3 trillion over 2026–2035 if temporary (net dynamic ~$1.1 trillion after growth drag); up to $2.2 trillion if permanent.
Businesses face higher input costs, supply chain disruptions, and inflation risks, with many costs passed to consumers (historical pass-through rates 31–90% in similar cases). Sectors like agriculture, manufacturing, and retail are particularly vulnerable without exemptions.
Trump argues the tariffs address trade deficits and protect US industries, but critics highlight reduced growth and higher costs outweighing benefits. Markets have shown restrained but negative responses amid policy confusion: US futures dipped. The dollar weakened ~0.3%, while gold rose as a safe haven.
Broader global stocks were flat to lower, with European and Asian indices selling off modestly. Volatility stems from uncertainty over exemptions, duration, and potential extensions or escalations; Trump has hinted at “more powerful” future measures. The tariff has heightened tensions, especially with allies under prior deals.
European Union: Officials describe “pure tariff chaos” and demand clarity, insisting “a deal is a deal” on the 2025 US-EU agreement which set ~15% on most EU exports in exchange for concessions. The EU may freeze ratification or suspend progress, with emergency meetings planned and retaliation threats. Some view the new 15% as potentially breaching or layering atop the deal.
United Kingdom: Confusion over whether the separate US-UK arrangement often at lower rates applies; estimates suggest £2–3 billion extra costs on UK exports to the US, risking supply chain disruptions in autos, aerospace, and pharma. Japan and South Korea likely face increases unless exempted; some allies see higher effective duties, while rivals may gain relative relief.
Potential retaliation, surplus goods flooding other markets, currency volatility, and weakened global growth. This is a temporary measure which expires ~July 2026 without action, but it signals Trump’s intent to pursue aggressive trade policies despite the Supreme Court’s February 20 ruling limiting emergency powers.
Businesses and investors face “tariff roulette,” with calls for carveouts and legal challenges likely. The situation could evolve rapidly with congressional involvement, further executive actions, or negotiations. Short-term effects center on inflation, uncertainty, and market jitters, while longer-term outcomes hinge on whether the tariff lapses or escalates into broader trade conflicts.
