Trump Unveils 10% Global Tariff Under Section 122 After Court Blocks IEEPA Use
President Trump unveiled a 10% global tariff on imports under Section 122 after a 6-3 Supreme Court ruling that struck down his emergency power use under IEEPA. The administration confirmed existing Section 232 and 301 tariffs remain in place while S&P 500 futures held steady.
1. Supreme Court Blocks IEEPA Authority
In a 6-3 decision, the Supreme Court ruled that the International Emergency Economic Powers Act does not authorize the president to impose tariffs, holding that only Congress can levy duties under Article I of the Constitution. The majority opinion emphasized separation of powers and limited unilateral executive trade actions.
2. New 10% Global Tariff Under Section 122
President Trump immediately signed an order implementing a 10% tariff on all imports under Section 122 of the Trade Act of 1974, which allows temporary duties up to 15% for 150 days to address balance-of-payments challenges. The move aims to replace the blocked IEEPA tariffs with a legally distinct authority.
3. Existing Trade Authorities Remain Active
The administration confirmed that national security tariffs under Section 232 of the Trade Expansion Act of 1962 and trade enforcement measures under Section 301 of the Trade Act of 1974 remain fully in effect. President Trump highlighted additional tools, including Section 338 of the Tariff Act of 1930, as part of a broader tariff strategy.
4. Market Reaction and Outlook
Equity markets showed little immediate response, with S&P 500 futures trading flat following the announcements. Investors are monitoring potential sector-specific impacts and await details on implementation and possible litigation over billions in previously collected tariff revenues.
