U.S Supreme Court ruling scrubs IEEPA duties; new 15% global levy reshapes trade risk
MARKET INSIDER – Vietnam has emerged as a relative beneficiary after the Supreme Court of the United States ruled that the president lacked authority to impose tariffs under the International Emergency Economic Powers Act (IEEPA), invalidating much of the 2025 tariff architecture. Within hours, President Donald Trump pivoted to a temporary 15% global tariff under Section 122 of the Trade Act of 1974—simpler, uniform, and capped at 150 days unless Congress extends it.
For Vietnam, the shift reduces nominal exposure from 20% to 15%, narrowing a competitive gap within ASEAN and lowering the estimated effective tariff rate to roughly 9.9% from about 12%, given electronics’ large, often tariff-exempt share of exports to the U.S.
What changed—and what didn’t. The April 2025 46% headline tariff and the August 2025 20% negotiated rate tied to IEEPA are no longer in effect. Bilateral understandings reached under that framework lose their legal anchor, though diplomatic commitments persist. The White House’s Section 122 levy preserves key exemptions (USMCA goods, Section 232 items, strategic minerals, energy, pharma, semiconductors, electronics), ushering in a temporary “reset” phase while Washington prepares alternative legal pathways.
Duration and next moves. Section 122 expires automatically after 150 days—around July 24, 2026—absent congressional action. Extension odds appear limited amid bipartisan skepticism and pre-midterm politics. However, the Office of the United States Trade Representative has initiated new Section 301 investigations into industrial overcapacity, forced labor, and digital barriers. Section 301 lacks the 150-day cap and can persist for years, though it requires a 6–12 month investigative process.
Vietnam-specific risks. Potential 301 focal points include transshipment of Chinese goods, FX management of the dong, and market access for U.S. tech firms. Notably, recent high-level engagement between Hanoi and Washington signaled easing export controls in AI and semiconductors—creating negotiating space and upside for value-chain upgrading. Compared with last year’s blanket tariff threat, any 301 measures are likely narrower and more targeted.
Investment lens. In the near term, reduced tariff pressure improves visibility for exporters and levels the regional playing field. The 150-day window offers operational certainty for order planning, and FDI flows may accelerate while rules are stable. Over the medium term, Vietnam’s domestic catalysts—public investment acceleration, legal reforms unlocking projects, real estate recovery, and prospects of emerging-market index inclusion—remain the primary drivers, largely independent of U.S. tariff mechanics.
Bottom line: the IEEPA ruling lowers immediate trade headwinds and buys time. The structural risk has shifted—not vanished—to Section 301. For investors, the opportunity lies in leveraging the current clarity while monitoring the investigation timeline and sector-specific exposure, particularly in electronics and textiles.
