U.S. Stocks Slide 1.55% as Hormuz Blockade Drives Oil Spike and Fed Hike Bets Reprice

U.S. equities sold off Tuesday as a sudden escalation in Middle East shipping risks collided with a sharp repricing of Federal Reserve tightening expectations. Donald Trump said the U.S. had reinstated a maritime blockade linked to Iran, introducing a 20% toll on goods moving through the Strait of Hormuz. U.S. Central Command confirmed the operation began Tuesday afternoon. After the announcement, commercial transits through Hormuz reportedly sank to just three vessels per 24 hours, a record low as shippers avoided the route. Crude prices surged, with WTI jumping nearly 10% to a one-month high and finishing back above its 50-day moving average. At the same time, Fed Governor Christopher Waller struck a hawkish tone in New York, saying that if this week's core inflation data re-accelerates, the FOMC would consider tightening policy in the near term. He warned that "inflation has been rising this year by any measure" and flagged concern about the path of core inflation. CME pricing flipped quickly, with the implied probability of a July rate hike rising from near zero to roughly 50%. Rates reacted forcefully. The 2-year Treasury yield rose 6 basis points to 4.28%. The 10-year real yield climbed to 2.34%, the highest since April last year, up from 2.11% at the end of June and approaching the closely watched 2.40% area. The U.S. Dollar Index gained more than 0.5% off its intraday low. Precious metals sold off, with spot gold sliding more than 3% to $3,992.48, breaking below the $4,000 level; spot silver also weakened. Equity Performance The S&P 500 fell 0.79% to 7,515.34 and the Dow Jones Industrial Average slipped 0.26% to 52,498.64. The Nasdaq Composite dropped 1.55% to 25,873.176, closing below its 50-day moving average, while the Nasdaq 100 declined 1.88% to 29,264.103. The Russell 2000 lost 0.83% to 2,953.166. Volatility spiked, with the VIX up 14.11% to 17.15. Semiconductors led the downturn. The Philadelphia Semiconductor Index sank 4.78% to 12,347.784, its lowest level in months. NVIDIA fell 3.52% to $203.53; Broadcom slid 3.98%; AMD lost 4.21%; Arm dropped nearly 8%; Micron sank more than 7%; SanDisk plunged over 12%. TSMC's ADR declined 2.88%. SK Hynix was hit especially hard: its U.S.-listed ADR fell more than 9%, and its Seoul-listed shares tumbled 15.37%, the largest single-day decline in the company's history. Mega-cap performance diverged. Apple rose 0.71% to $316.91, setting a new intraday high, while Microsoft gained 1.53% and Amazon added 0.80%. Meta fell 1.86%, Tesla dropped 3.19%, and Alphabet Class A lost 1.31%. The Magnificent Seven Index fell 0.96%. In ETFs, the semiconductor ETF dropped 4.16%, the global technology stocks index ETF fell 2.88%, and the energy sector ETF climbed 3.03%. Digital assets weakened alongside risk appetite: Bitcoin fell more than 3% and briefly dipped below $62,000; Ethereum declined about 3%. Macro Outlook Goldman Sachs maintained a baseline view for Brent crude to trade between $75 and $85. The bank warned that prices could spike above $100 if U.S. forces directly strike maritime energy infrastructure or if multiple key straits face simultaneous disruptions. Strategists also pointed to the speed of the real-rate move as a key risk for equities. With the 10-year real yield nearing 2.40%, a decisive break higher could translate into broader pressure across stocks, while also supporting the dollar and weighing further on gold. AI-linked sentiment deteriorated sharply. Investors have increasingly questioned whether the current AI capex cycle can be sustained, shifting from demand concerns to doubts about the overall investment cycle. A steep selloff in Korea added to the pressure: the Korean market fell 8.95% and is down 27% from its June high, and the move spilled into U.S. trading through heavy selling in AI infrastructure and chip names. SK Hynix's record one-day drop was widely read as a signal that expectations for memory-chip demand are cooling rapidly. Against that backdrop, Apple's relative strength drew fresh inflows. The stock has risen in 13 of the past 16 weeks and sits about 5% away from overtaking NVIDIA as the world's most valuable company. Market participants are split on the driver: some cite an autumn upgrade cycle and stable gross margins, while others see a defensive rotation within tech from higher-volatility AI and memory names into lower-volatility balance-sheet strength. What to Watch Markets now face two immediate catalysts: Wednesday's CPI release and any further developments around Hormuz. A hotter inflation print would reinforce Waller's message and could push hike expectations higher, leaving room for additional downside in U.S. equities. Whether Apple's outperformance persists may hinge on next quarter's earnings season and whether companies confirm any pullback in AI spending. Article by: Tide Research
