Trump Increases Global Tariff To 15% Following Supreme Court Defeat

United States President Donald Trump announced on Saturday a hike in global import duties to 15 per cent, intensifying his tariff agenda just one day after the Supreme Court ruled much of his trade policy unlawful. According to Ireporter Online, the move represents a significant escalation in Washington’s trade stance, setting the stage for extended legal and diplomatic challenges.

In a 6-3 decision on Friday, the Supreme Court struck down the president’s use of a 1977 economic emergency powers law to impose sweeping tariffs, marking one of Trump’s most consequential judicial setbacks since returning to office 13 months ago. The ruling invalidated the administration’s signature tariff policy, which has disrupted global markets and reshaped international trade relations.

Trump swiftly responded, using his Truth Social platform to describe the judgment as an “extraordinarily anti-American decision” and announced that, following a review, his administration would increase global import levies “to the fully allowed, and legally tested, 15% level.” Initially, an alternative legal provision had allowed him to implement a 10 per cent global tariff, but Saturday’s adjustment raised the rate further.

The political ramifications were immediate. Several Republicans criticized conservative justices who sided with the majority, accusing them of disloyalty, while Trump praised Justices Clarence Thomas, Samuel Alito, and Brett Kavanaugh for upholding his authority. He further alleged that the six-member majority, including two justices he nominated, had been influenced by foreign interests.

Global reactions have been swift. Brazil’s President Luiz Inácio Lula da Silva called for fairness in trade and cautioned against confrontation. In Europe, German Chancellor Friedrich Merz announced plans to coordinate with European allies on a collective response ahead of a planned Washington visit. Within the United States, Democratic leaders, including Pennsylvania Governor Josh Shapiro, urged Trump to respect the court’s ruling, citing the impact of tariffs on farmers, businesses, and families. Conversely, business groups welcomed the decision, with the National Retail Federation noting it offers “much-needed certainty” for companies navigating unpredictable trade policies.

According to Ireporter Online, the White House indicated that the 15 per cent global tariff is a temporary measure valid for 150 days and remains legally permissible. Exemptions are in place for certain sectors, including pharmaceuticals and goods covered under the US-Mexico-Canada Agreement. Existing duties on steel, aluminum, and other goods remain in effect, and additional sector-specific tariffs could still be imposed. Companies may receive refunds if tariffs are ultimately ruled unlawful, though the Supreme Court did not address this issue directly. Trump acknowledged that ongoing litigation could last for years, with Justice Kavanaugh warning that the refund process could become highly complex.
