In a dramatic escalation of trade policy, U.S. President Donald Trump announced Saturday he would impose a sweeping 15% tariff on imports from all nations, defying a Supreme Court ruling that had declared his previous tariff measures unlawful. The decision comes just one day after Trump instituted a 10% worldwide duty in response to the judicial setback.
Trump made the announcement through social media, declaring: “I, as President of the United States of America, will be, effective immediately, raising the 10% Worldwide Tariff on Countries, many of which have been ‘ripping’ the US off for decades, without retribution (until I came along!), to the fully allowed, and legally tested, 15% level.”
The move follows Friday’s Supreme Court decision, which ruled 6-3 that Trump’s use of the International Emergency Economic Powers Act to implement tariffs exceeded presidential authority. The ruling represented a significant judicial check on executive power in trade matters.
Trump’s administration now faces the complex task of developing a new legal framework for these tariffs within coming months. The president promised his team would “determine and issue the new and legally permissible Tariffs,” which he characterized as part of “our extraordinarily successful process of Making America Great Again – GREATER THAN EVER BEFORE!!!”
The immediate economic implications are substantial, as the increased tariff rate will affect virtually all imported goods entering the United States, potentially triggering retaliatory measures from trading partners and affecting global supply chains already adjusting to the previous day’s announcement.
