WSJ editorial and strategists warn Trump’s new Section 301 tariffs raise legal and macro risks

The Trump administration’s new Section 301 tariffs of 10% and 12.5% on more than 60 countries took effect Friday after temporary 10% worldwide tariffs expired, and critics, legal challengers and market strategists say the move could carry broader political, legal and macroeconomic consequences. The White House says the tariffs are tied to forced-labor enforcement, with countries that have adopted or committed to introducing prohibitions facing 10% duties and those that have not facing 12.5% charges. Analysts said the initial market reaction was muted because investors had largely expected a replacement for the expiring duties, but warned the measures are landing in a more fragile environment marked by U.S.-Iran conflict, oil prices above $100, supply-chain bottlenecks and persistent inflation pressure. CG Asset Management said investors should position for a low-growth, high-inflation, or stagflationary, outcome, while others said the administration’s shift to Section 301 after the Supreme Court struck down previous tariffs in February suggests import levies could become a more lasting feature of U.S. economic policy. Foreign governments including Brazil and Australia have disputed the tariff rationale, and legal challenges are mounting, including a pending challenge to the Section 301 tariffs and a Liberty Justice Center lawsuit filed Friday on behalf of small businesses. The Wall Street Journal editorial board and some Republican strategists have argued the expanding tariff push could become a political liability ahead of the midterms, while analysts said attention is shifting to next week’s Federal Open Market Committee announcement as higher oil prices raise the possibility the Fed keeps the option of a rate hike open later this year.
