US-Iran strikes enter sixth day as chip selloff hits Wall Street and Tokyo — July 17, 2026

Top U.S. Stories

• The U.S. and Iran traded strikes for a sixth consecutive day, with U.S. Central Command hitting Iranian command centers and missile sites while Iran targeted U.S. bases in Gulf states. Why it matters: the June ceasefire has effectively collapsed, and shipping through the Strait of Hormuz — a key global oil chokepoint — has dropped to a fraction of normal volume, keeping upward pressure on crude prices.
• Alphabet shares sank more than 4% after reports that its next flagship AI model, Gemini 3.5 Pro, is running months behind schedule, compounding investor worry about the company’s rising 2026 capex and shrinking free cash flow margin. Why it matters: it signals growing market unease that AI spending is outpacing near-term payoff across Big Tech, not just at Alphabet.
• U.S. stocks fell as chip stocks tumbled even after Taiwan Semiconductor (TSMC) reported a 77% jump in quarterly profit, because investors focused on the company’s expanded capital spending plans, including an additional $100 billion in Arizona.
• July 17 brings a batch of U.S. economic data — June housing starts, building permits, industrial production, and the preliminary University of Michigan consumer sentiment index — along with earnings from Travelers, Truist Financial, and Fifth Third Bancorp.
• A fire at a Bangkok music bar earlier this week has claimed 33 lives, including four members of the band performing when the blaze broke out.
• The World Cup final is set: Argentina will face Spain on July 19 in New Jersey, the first-ever World Cup final meeting between the two nations.

Markets

U.S. equities closed lower on Thursday, July 16: the S&P 500 fell 0.51% to 7,533.77, the Nasdaq Composite dropped 1.47% to 25,881.95, and the Dow slipped 0.20% to 52,552.97, dragged down by a renewed semiconductor selloff and Alphabet’s slide. In Tokyo, the Nikkei 225 tumbled 1,915.97 points (-2.79%) to 66,835.54, its first drop in three sessions, as chip-related names like Tokyo Electron and Advantest followed Wall Street’s tech weakness lower. WTI crude held near $79 a barrel, extending a three-day rise on the ongoing U.S.-Iran conflict, while the dollar stayed near a historic high against the yen at ¥162.20 (ECB reference rate, July 16).

Stocks in Focus

• Alphabet (GOOGL) — down more than 4% on reports its Gemini 3.5 Pro model is delayed, alongside concerns about 2026 capex eating into free cash flow.
• TSMC — record quarterly profit (+77.4% year-on-year) but shares under pressure as investors weigh the cost of its expanded U.S. investment plans.
• Chip stocks broadly (Tokyo Electron, Advantest, and U.S. peers) — sold off in sympathy with the AI-capex-fatigue narrative on both sides of the Pacific.
• Energy and shipping names — remain in focus as the Strait of Hormuz standoff continues to disrupt tanker traffic and support oil prices.

Compass Insight

Today’s market story isn’t really about the numbers in the earnings reports — it’s about what comes after them. TSMC posted record profit and Alphabet keeps growing revenue, yet both stocks fell, because investors are increasingly wary that ballooning AI capital spending is outrunning near-term returns, a worry that spilled straight into Tokyo’s chip names and knocked more than 2.7% off the Nikkei. Layered on top is the Strait of Hormuz standoff, now in its sixth day with no ceasefire in sight — as long as it drags on, oil prices are likely to stay elevated, and combined with the yen’s historic weakness near ¥162, that’s a setup that tends to feed through into fuel, utility, and import costs over time rather than all at once. In the near term, the trajectory of the U.S.-Iran conflict and oil prices remains the dominant variable to watch; over the medium term, how much further markets will tolerate rising AI infrastructure spending — and how the U.K.’s incoming government under Andy Burnham approaches issues like Ukraine support — are worth keeping an eye on. None of this amounts to a directional call; it’s simply where the current sits.
