Real-time vessel transit data for the Strait of Hormuz and Bab al-Mandab chokepoints. Data covers 2019 to present, sourced from IMF PortWatch AIS vessel tracking. Updated weekly.
Strait of Hormuz — Current Status (2026)
Tanker transits through the Strait of Hormuz have fallen approximately 92–93% since the Iran-US conflict escalation on February 28, 2026. Pre-crisis baseline was 51 tankers per day. Current transits are near zero. Approximately 93% of daily tanker DWT capacity — representing roughly 20% of global seaborne oil supply — is offline.
Bab al-Mandab — Current Status (2026)
The Bab al-Mandab strait connecting the Red Sea to the Gulf of Aden has shown partial continued traffic compared to Hormuz, reflecting some rerouting of non-Gulf origin vessels. Pre-crisis baseline was approximately 12 tankers per day.
Historical Context
The Strait of Hormuz is the world's most critical oil chokepoint, carrying approximately 21 million barrels per day at peak — around 20% of global petroleum consumption. Hormuz tanker traffic began declining through H2 2025 before the February 28 crisis accelerated the collapse. This dataset tracks the complete 2019–present traffic history across all vessel types.
