Trump Raises Global Tariff to 15% After Court Ruling, Escalating Legal and Economic Tensions

Washington | EcoPulse24

U.S. President Donald Trump announced an immediate increase in the global tariff rate from 10% to 15%, just hours after setting the previous level. The escalation follows a Supreme Court ruling overturning his use of emergency economic powers to impose wide-ranging reciprocal tariffs. This decision has renewed market volatility and exposed the White House's trade agenda to fresh legal and legislative tests.

Trump set the 15% tariff to take effect immediately via a social media post, superseding the 10% rate that was scheduled to start on February 24 at 12:01 a.m. Washington time. The increase re-prices supply chain risks and raises the potential cost burden on imports.

The move came after a 6–3 Supreme Court decision found the administration had overstepped constitutional authority by using the International Emergency Economic Powers Act (IEEPA) for broad tariffs. In response, Trump invoked Section 122 of the 1974 Trade Act, allowing tariffs for 150 days without congressional approval - a limited window subject to new legal challenges. Tariffs imposed under Sections 301 and 232 remain, and Trump ordered expedited 301 investigations that could lead to country- and sector-specific tariffs.

This development reshapes compliance requirements for a wide range of trading partners, with expectations that investigations may expand to cover industrial overcapacity, forced labor, drug pricing, digital taxes, and practices related to seafood and rice. The White House is also considering tariffs between 15% and 30% on foreign cars, while maintaining NAFTA exemptions for certain goods and agricultural products. Over 1,500 companies have filed trade court lawsuits in anticipation of the ruling, signaling a wave of extended disputes.

The court decision raises questions about previously collected tariffs, as it did not resolve whether importers are entitled to refunds, leaving the matter to lower courts. This creates potential financial exposure of up to $170 billion - over half of total tariff revenues. The Treasury Department, however, expects tariff revenue projections for 2026 to remain "largely unchanged." Politically, the tariff escalation coincides with the upcoming State of the Union address, where Trump faces criticism from Democrats and some Republicans over his trade approach.

EcoPulse24 Analysis:
The rapid shift from 10% to 15% reflects the administration's effort to retain trade leverage after losing the emergency powers route, but shifts the risk from a "specific legal dispute" to a "broad tariff escalation via a temporary mechanism." The 150-day window offers tactical flexibility but keeps legal certainty low, likely prompting further challenges. Economically, the tariff hike increases import costs and the risk of price pass-through at a time when markets are closely watching inflation and growth. Volatility is expected to persist, with tariff policy to be shaped by the interplay between courts, Congress, and the White House in the coming weeks.
