Chokepoint Report — week of 17 August 2026

Vessel movements through the world's maritime chokepoints, 17 August to 23 August 2026. Every transit below was detected from live AIS positions and screened against OFAC, EU, UN and UK sanctions lists.

6,435 transits recorded across 10 chokepoints. 104 involved a vessel on a sanctions list.

Traffic by chokepoint

No week-on-week comparison this issue. Our AIS coverage was materially lower in the previous week (89,382 position records this week against 0 the week before), so any percentage change would measure our own data collection rather than shipping activity. The counts below are what we observed; the comparison returns once both weeks are comparable.

Direction of travel

Through the English Channel: 1,095 southbound, 1,034 northbound.

AIS gaps

193 voyage legs from 193 vessels included a period with no AIS signal. A gap is not itself evidence of wrongdoing — coverage is imperfect and transponders fail — but it is the pattern sanctions-evading operators use, and it is why we track it.

Cargo movements

Draught changes indicating 735 loaded, 725 discharged, inferred from AIS-reported draught against each vessel's laden and ballast baseline.


Method: transits are detected by tracking vessels across zone boundaries in live AIS data. Sanctions status is matched on IMO and MMSI against the published lists and refreshed daily. Figures are what we observed; AIS coverage is not complete, so treat them as a floor rather than a census.

See it live. These figures come from the same feed behind our live chokepoint maps — every vessel currently transiting, screened against OFAC, EU, UN and UK lists.
