The Supreme Court delivered a significant blow to a large portion of President Trump’s tariff framework, triggering an initial market rally that quickly faded as investors digested the fine print. While the decision removes a substantial set of levies, it stops far short of dismantling the entire tariff regime, leaving key industries still exposed.
Major ETFs including SPDR S&P 500 ETF Trust $SPY ( ▼ 0.3% ) , Invesco QQQ Trust $QQQ ( ▼ 0.07% ) , and iShares Russell 2000 ETF $IWM ( ▲ 0.5% ) jumped immediately after the ruling before giving back much of the gains, a sign that traders view the outcome as complicated rather than decisively bullish.
Why automakers aren’t celebrating
The ruling applies to tariffs imposed under the International Emergency Economic Powers Act, not Section 232, which governs the hefty 25% duties on automobiles and auto parts. Those automotive tariffs remain fully intact, meaning companies like Ford $F, General Motors $GM, and Stellantis $STLA still face the bulk of their tariff-related costs.
However, the decision does remove duties on certain machinery, raw materials, and components that feed into auto production. Analysts estimate those IEEPA tariffs added about $250 per vehicle for Detroit’s major automakers, far less than the roughly $4,240 per vehicle impact from Section 232 tariffs, but still meaningful.
Retailers and import-heavy companies see bigger boost
Stocks most sensitive to consumer imports reacted more strongly. Companies previously viewed as “tariff losers,” including e.l.f. Beauty $ELF, RH $RH, Crocs $CROX, Stanley Black & Decker $SWK, Deckers Outdoor $DECK, and Williams-Sonoma $WSM, surged early as investors priced in lower input costs and reduced pricing pressure.
The decision affects tariffs that generated roughly $170 billion in revenue through February, underscoring the scale of what’s at stake.
Relief today, uncertainty tomorrow
Any optimism is tempered by the likelihood that tariffs will remain a central policy tool. Administration officials have already signaled contingency plans using alternative legal authorities, and the president called the ruling a “disgrace,” indicating a willingness to reimpose levies through other mechanisms.
Legal and logistical complications may also follow. Questions about refunds for tariffs already paid could create years of disputes, with one justice warning the process could become chaotic.
For markets, the takeaway is that the tariff story isn’t over, it’s just entering a new phase. The ruling reduces some costs and removes uncertainty in one area, but the broader trade landscape remains fluid, leaving companies and investors navigating a policy environment that can shift quickly.
