US Stock Market Falls as Hormuz Tensions Rattle Wall Street

Reasons for Today's Stock Futures Drop

Oil price surge and AI trading have caused the fall.

Oil Price Surges after Iran’s Strike

Oil jumped as the US extended strikes on Iran for a sixth day near the Strait of Hormuz, reviving inflation and supply worries after last week’s sudden stock drop. WTI  futures rose 9.4% to top $78 per barrel, and Brent surged 9.6% to $83 per barrel. Trump said,

“We are reinstating the IRANIAN BLOCKADE, so named because it is only stopping Iran’s ships or customers from entering or leaving.”

SK Hynix Led a Broad Chip Stock Selloff

The AI trade unwound further after Goldman Sachs cut SK Hynix, a key memory-chip supplier, to Neutral, warning that high-bandwidth memory prices could weaken. Its US-listed shares slid about 9% and dragged Micron down roughly 4%, while AMD, Intel and Broadcom each fell more than 5%.

AI Valuation Fears Spread Beyond Chips

Investor nerves widened after Taiwan Semiconductor lifted its 2026 spending plan to $60 billion to $64 billion, a signal that costs, not demand, are now the harder test. Megacap names, including Nvidia, Alphabet, and Meta, also closed lower as traders questioned stretched AI valuations.

Key Movers to Watch

• Netflix (NFLX): down more than 8% after hours after guiding Q3 revenue to about $12.86 billion, below the roughly $13 billion analysts expected.
• SpaceX (SPCX): fell about 6% to near $131, dropping below its $135 
• Burberry (BRBY): dropped about 5% in London after a cautious outlook
• S&P 500: 7,533.77, down about 0.5%
• Dow Jones Industrial Average: 52,552.97, down about 0.2% (105.67 points)
• Nasdaq 100 futures: down about 1.1% (vs S&P 500 futures down about 0.4%)
• CBOE Volatility Index (VIX): near 16.7, up about 6%

Technical Indicators and Trends

The tone is risk-off. Nasdaq 100 futures are falling more than twice as fast as the S&P shows money rotating out of megacap tech. 

The 10-year US Treasury yield near 4.56% keeps pressure on richly valued shares. Chip stocks and the semiconductor ETF (SMH) are the levels traders are watching: stabilisation would hint the US stock market sell-off is cooling, while fresh lows would confirm the downtrend.

Market Sentiment

• High-impact event ahead. Traders should brace for today's University of Michigan Consumer Sentiment Index at 10 am ET, forecast 50.4 versus 49.5 prior. 
• A stronger reading is generally USD-positive, while a miss can pressure the dollar and add volatility to an already jittery US stock market. 
• For beginners, this is a defensive backdrop: many traders are trimming exposure to high-valuation tech, watching oil and chip levels, and waiting for the data rather than chasing the move.
