Summary
Daily ship transits through the Strait of Hormuz by vessel type, from IMF PortWatch
Description
Daily vessel transit counts through the Strait of Hormuz, sourced from the IMF PortWatch platform. Data derived from AIS satellite vessel tracking via the UN Global Platform.
Coverage: January 2019 – present (updated weekly, Tuesdays)
Vessel categories: Tankers, dry bulk, container, general cargo, RoRo
The 7-day rolling average smooths out day-of-week variation in reporting. Tanker transits are highlighted as the dominant traffic type through this chokepoint — roughly 20% of global oil supply passes through the Strait of Hormuz.
