Trump Threatens New Tariffs After Supreme Court Ruling

Washington – Former President Donald Trump warned countries against backing away from recently negotiated trade deals with the U.S. After the Supreme Court struck down his emergency tariffs, stating he would impose higher duties under different trade laws. The move has injected further uncertainty into the global economy.

Supreme Court Ruling on Trump’s Tariffs

On February 20, 2026, the Supreme Court ruled that Trump exceeded his authority when imposing sweeping tariffs using the International Emergency Economic Powers Act (IEEPA), a 1977 law reserved for national emergencies . The decision, 6-3, invalidated many, but not all, of Trump’s tariffs.

Trump’s Response and New Tariffs

Trump harshly criticized the Supreme Court majority, calling the decision a “disgrace” and accusing the justices in the majority of being “unpatriotic” and “disloyal to the Constitution” . Despite the ruling, Trump announced a new global 10% tariff, effective Tuesday at 12:01 a.m. ET, citing his authority under Section 122 of the Trade Act of 1974 .

In a series of social media posts, Trump warned countries against “playing games” with the Supreme Court decision, threatening even higher tariffs on nations he accused of “ripping off” the U.S. For years .

Impact on Global Trade and Economy

The Supreme Court’s ruling and Trump’s subsequent actions are exacerbating global trade tensions . Economists predict that the uncertainty will lead foreign governments and businesses to adopt more cautious approaches to investment and trade, potentially harming the U.S. Economy . Some countries are already diverting trade to China, which saw a spike in exports and imports at the end of last year .

European Union leaders have expressed dismay over the new tariffs, arguing they will disrupt existing trade deals . The EU postponed a key vote on its deal with the U.S. In response to the tariff threats.

Looking Ahead

Whereas the Supreme Court clipped Trump’s power to impose tariffs under IEEPA, his ability to do so through other laws remains intact. The situation remains fluid, and further trade actions are expected as the global economy adjusts to these developments.
