President Trump has increased his proposed global tariff from 10% to 15%, utilizing Section 122 of the 1974 Trade Act to bypass a recent Supreme Court setback. This temporary measure lasts 150 days, creating immediate volatility for global supply chains as the administration seeks more permanent legal avenues for its protectionist agenda.
Following a Supreme Court ruling that struck down the use of emergency powers for trade levies, President Trump has invoked Section 122 of the Trade Act of 1974 to impose a 10% global tariff. The move recalibrates trade costs for partners like India and introduces a 150-day window of heightened supply chain volatility.
The U.S. Supreme Court has ruled 6-3 that President Trump overstepped his executive authority by using the International Emergency Economic Powers Act to impose sweeping global tariffs. In immediate defiance, the White House announced a new 10% worldwide tariff and signaled a protracted legal battle over potential tax refunds for importers.
The U.S. Supreme Court has issued a landmark 6-3 ruling stripping the executive branch of unilateral tariff-setting authority, nullifying billions in existing duties. President Trump immediately defied the spirit of the ruling by invoking emergency powers to impose a new 10% blanket tariff for 150 days.
The US Supreme Court ruled 6-3 that the executive branch cannot use the IEEPA to impose broad-based tariffs, leading the Trump administration to immediately pivot to Section 122 of the Trade Act of 1974. This shift introduces a 10% global tariff surcharge and a new 150-day window of regulatory uncertainty for global supply chains.
