Overnight Developments
Record tanker attacks in the Strait of Hormuz push oil past $100 — KRDO (wire), published 2026-10-08 04:34 ET
Kpler counted 10 tankers struck in the Strait of Hormuz between September 28 and October 4 — a record week, above the previous high of six. In the latest attack, on Wednesday, a tanker reported being hit by “multiple projectiles,” causing casualties, according to the UK Maritime Trade Operations agency. Traffic is thinning in response: only seven tankers transited the strait on Tuesday, less than half the seven-day average and the fewest since July 23.
Crude has repriced hard. Brent is up +5.1% to $105.35 and WTI +5.1% to $92.78 as of 07:00 ET, extending the move reported overnight. The December WTI contract is up 4.8% alongside the November contract, and the curve is in backwardation — the signature of a genuine supply disruption rather than a futures roll artifact.
Affected sectors: Energy (positive), Airlines, Transportation, Semiconductors, Consumer Discretionary.

Watchlist Movers
No watchlist name cleared the 3% alert threshold, but the list is almost uniformly red, led by semiconductors and high-beta nuclear names (pre-market, ~07:00 ET):
- INTC -2.9%
- SMCI -2.3%
- SMR -2.2%
- RKLB -2.1%
- OKLO -2.1%
- TEM -1.9%
- TSM -1.5%
- MSTR -1.4%
A scan for company-specific catalysts on these names turned up nothing dated October 7 or 8. Treat these as broad market beta, not single-stock stories. One calendar item worth noting: TSMC’s September monthly sales release is scheduled for today — a scheduled release, with no figures out yet.
International Markets
Asia closed broadly lower and Europe is following. Korea took the worst of it.
| Index | Level | Change |
|---|---|---|
| Kospi | 6,625.93 | -2.62% |
| Hang Seng | 23,785.79 | -1.43% |
| Nikkei 225 | 69,042.11 | -1.42% |
| Sensex | 71,593.24 | -1.44% |
| DAX | 24,825.60 | -1.11% |
| Shanghai Composite | 3,811.90 | -0.79% |
| ASX 200 | 8,660.90 | -0.77% |
| FTSE 100 | 10,406.40 | -0.50% |
Note on Shanghai: mainland China returned today from the National Day holiday (closed October 1–7), so that -0.79% is measured against the September 30 close and absorbs a full week of news, not one overnight session.
What to Watch at Open
The question at the open is whether this is an energy-supply shock the market can compartmentalize or the start of a broader de-risking — watch whether energy strength holds while semis stabilize, or whether selling broadens past the oil-sensitive names. With crude up 5% and the 10-year near 5.28%, the inflation-plus-yields combination is the squeeze point, and any further Hormuz headline during the session is the obvious catalyst for leg two.
