Tariff Hike Announced After Supreme Court Setback
US President Donald Trump has announced an immediate increase in global tariffs on goods entering the United States. The new tariff rate rises from 10 percent to 15 percent. The decision was revealed on Saturday through his Truth Social platform.
The move comes one day after the US Supreme Court largely struck down Trump’s sweeping tariff programme. The court ruled that Trump exceeded his authority under the International Emergency Economic Powers Act (IEEPA) when imposing higher tariffs under emergency powers.
Following Friday’s court decision, Trump had already announced a flat 10 percent tariff across all imports. Now, he has increased that rate to the maximum 15 percent allowed under a separate trade law.
The new tariffs are grounded in Section 122 of US trade law. This provision allows the president to impose tariffs of up to 15 percent for 150 days. However, extending them beyond that period requires congressional approval.
Trump described the Supreme Court’s ruling as “extraordinarily anti-American.” He said the administration reviewed the decision carefully before announcing the revised tariff rate.
Section 122 Provides Legal Cover for Tariff Policy
The Supreme Court’s ruling marked one of the most significant legal setbacks for Trump since returning to office. The conservative-majority court ruled that IEEPA does not authorize the president to impose tariffs in the manner used by the administration.
By shifting to Section 122, the White House aims to provide stronger legal footing for the tariff policy. Trump stated that the 15 percent rate is “fully allowed and legally tested.”
In his social media statement, Trump said the administration will determine and issue new legally permissible tariffs in the coming months. He framed the policy as part of his broader “America First” economic agenda.
Trump has consistently used tariffs as both an economic and foreign policy tool. He argues that import taxes protect American manufacturing and reduce trade imbalances. Critics warn that higher tariffs can increase consumer prices and strain global trade relationships.
Global Reaction and Economic Impact
The Supreme Court ruling was welcomed by Canada, which described the earlier tariffs as unjustified. Other major trading partners responded more cautiously. The United Kingdom, Germany, and the European Union said they are reviewing the court’s decision and remain in contact with US officials.
Trump’s tariff strategy has been central to a global trade war launched during his second term. The policy has affected financial markets and contributed to global economic uncertainty. Several allies have expressed concern over the long-term impact on trade stability.
The administration previously projected that tariffs could generate trillions of dollars in revenue over the next decade. However, updated tariff collection data has not been released since December 14, 2025.
With the new 15 percent global tariff now in effect, businesses and international partners are closely monitoring Washington’s next steps. The coming months will determine whether Congress supports extending the higher rate or seeks to curb the administration’s trade authority.
