What moved
No US opening bell today. The NYSE, Nasdaq and the Treasury market are closed for Labor Day, and index futures shut early. Friday's closes remain the last cash prints: the S&P 500 finished 0.38% lower at 7,718.60, the Nasdaq Composite 0.29% lower at 26,506.99 and the Dow 0.51% lower at 53,414.25. S&P 500 and Nasdaq 100 futures are the only live read on the American day and they are quoted unchanged from Friday's settlement, at 7,722.00 and 29,565.25 — a blank rather than a signal.
Asia has done the work instead. The Nikkei 225 ended 2.12% higher at 66,399.84 and the Kospi 4.61% higher at 6,995.39, with Taiwan's benchmark up 1.67%; the Hang Seng closed 0.93% lower at 25,413.12 and the Shanghai Composite was flat, up 0.07%. Europe is mid-session and split: the FTSE 100 is 0.21% higher at 10,853.48 and the CAC 40 up 0.18%, against a DAX down 0.31% and the Euro Stoxx 50 a shade lower.
Why
The weekend brought a sharp escalation in the US–Iran tanker war. American forces destroyed or disabled three Iranian tankers on Saturday after the Revolutionary Guard fired ballistic missiles at two US Navy warships in the Gulf; Tehran has promised a 'more painful response'. The market response is more restrained than the headlines imply. Brent is unchanged on the day at $96.28 and WTI at $91.48, though both carry the escalation of the past month — Brent is 9.76% higher over four weeks and 58.49% higher this year. Gold is doing the hedging instead, up 1.06% at $4,476.60, helped by a dollar index 0.28% softer at 98.883.
Asia's rally is a separate, cleaner story: optimism around OpenAI's next-generation model has revived the memory-and-AI-hardware trade, lifting Samsung Electronics and SK Hynix in Seoul and the chip complex in Tokyo, and extending Friday's strength in US semiconductor names.
The brake on all of it is rates. Friday's August payrolls came in at 162,000 against consensus nearer 53,000, with unemployment steady; yields rose across the curve — the 10-year up 2.2 basis points to 4.784% and the 5-year up 4.1 basis points to 4.550% — and futures now imply roughly a 60% chance the Fed raises rates next week. Higher long yields compress the value of distant profits, which is exactly where the AI enthusiasm sits.
Sentiment & risk appetite
Risk appetite is intact but jumpy. The VIX is quoted at 15.24, up 4.89%, historically low but firming; the MOVE index of rates volatility ended Friday at 73.10, down 2.11%, so the bond market is not pricing panic ahead of the Fed. Our own US breadth for Friday was barely positive — 3,012 advancers against 2,743 decliners across our listed universe, a 1.10 ratio — for a tape that fell at the index level, the mark of narrow, name-specific damage rather than broad selling. Sector dispersion tells the same story: technology added 0.7% while consumer discretionary fell 1.33%, communication services 1.19% and health care 1.04%. Gold's bid and a weaker dollar are the only clear defensive tells.
Economic calendar
Nothing prints in the United States today. The Labor Day holiday closes the cash equity and Treasury markets, and there is no 08:30 ET release; Europe's session is running on the geopolitics and on Friday's American data rather than anything new.
That data is still the reference point: August non-farm payrolls landed at 162,000 on Friday, far above a consensus of roughly 53,000, with the unemployment rate unchanged and July's figure revised higher. The next scheduled test is August CPI on Friday 11 September at 08:30 ET, followed by the FOMC meeting on 15–16 September. US trading resumes at the normal time on Tuesday.
Earnings
No issuer of consequence reports today with the US market shut, so the live earnings story is still Friday's. Lululemon closed 17.38% lower at $100.61 after its third guidance cut of the year, on volume more than thirteen times its usual, even though second-quarter earnings beat. The wider pattern was brutal for software — Guidewire fell 19.93%, Fair Isaac 16.68%, UiPath 16.63% and Autodesk 8.26% — while chip-adjacent names went the other way, with Sandisk up 11.90%.
