Strait of Hormuz Ship Transits — Statistics by Year and Month

Overview

Daily commercial ship transits of the Strait of Hormuz — the passage carrying roughly a fifth of the world's petroleum liquids — counted by month and by year since January 2019, from AIS transit calls compiled by IMF PortWatch (tankers plus cargo ships; warships and vessels sailing dark are not counted). The series spans the 2019 tanker war, the grey-zone seizures of the following years and the collapse of commercial traffic after the opening strikes of the 2026 Iran war. Figures are updated as PortWatch publishes, typically weekly with a lag of about ten days.

Reading the Numbers

2026 has recorded 4,655 transits through August 9 — 74% below the 17,786 logged by the same point of 2025.

The busiest month on record is July 2024 with 2,934 transits.

The quietest month on record is March 2026 with 86 transits. It came in the wake of a logged incident: US opening strikes destroy Iran's fleet at Bandar Abbas as Hormuz transits collapse.

The single-day record — 130 transits on July 11, 2024 — compares with an all-time daily average of 70.9.

The longest pause is 4 consecutive days without a single reported entry, starting May 5, 2026.
