Only eight vessels crossed the Strait of Hormuz on November 1, 2026, according to maritime intelligence firm Windward, including three vessels operating without AIS signals. Four entered the Arabian Gulf and four departed, while GPS interference affected 478 vessels across the wider Gulf monitoring region. A separate AIS-only monitoring service recorded 10 commercial crossings that day against its pre-conflict baseline of 84.8 daily, indicating an approximately 88% reduction in detectable traffic. The two services use different vessel definitions and detection methods, but both establish that shipping remains severely restricted rather than completely stopped. Windward also reports that traffic held up despite fresh tanker attacks, with approximately 24 AIS-visible transits during the October 30–November 1 reporting window, compared with 18 in the preceding equivalent period.
Eight Crossings. Three Dark. Shipping Far Below Normal.
The November 1 traffic picture reflects a deeply restricted waterway, not a confirmed day with zero vessel movements.

Traffic compared with the pre-crisis baseline
Like-for-like figures from the independent AIS-visible commercial-ship monitor, not Windward's separate vessel universe.
A vessel-count comparison, not an estimate of oil barrels or LNG cargoes lost.
A Vessel Crossing Is Not the Same as a Cargo Shipment
New ship-tracking observations, historical EIA commodity flows and recycled reporting must be evaluated on separate terms.
