Chokepoint traffic holds, risks shift • • #MarineTraffic data show vessel traffic remained active through Hormuz and Bab el-Mandeb last week, although headline volumes mask significant changes in the underlying mix. Hormuz recorded 121 crossings, up 2.5% from 118. Laden crossings fell 27% to 35, while ballast movements rose to 61 and sanctioned crossings increased from 9 to 16. Iran’s unilateral routing scheme accounted for 46.3% of crossings. • • Bab el-Mandeb recorded 269 crossings, up 3.1% and roughly 2.2 times Hormuz volumes. Laden transits increased to 131, while dark transits fell from 23 to 15. • The figures show why vessel-level tracking matters when assessing changing maritime risk.

What is this event about?
This market will resolve according to the total number of transit calls that IMF Portwatch reports for the Bab el-Mandeb Strait for all days from August 17, 2026, through August 23, 2026, inclusive.
Transit calls include container, dry bulk, roll-on/roll-off, general cargo, and tanker ships. Ships not reported by IMF Portwatch will not be considered.
This market will resolve as soon as all relevant data has been published. If the relevant data is not published within 14 calendar days of the specified date, this market will resolve based on the most recent data published up to that point.
In case of obvious data integrity issues (i.e., erroneous data), the market may remain open until the end of the third calendar day (ET) after the date on which such data is first released to allow for corrections. Data integrity issues refer only to clerical or other similar errors in the underlying data, and do not include cases where IMF Portwatch differs from alternative sources.
Only revisions to previously published data points made before all relevant data has been published will be considered.
The resolution source for this market will be IMF PortWatch, specifically the “Arrivals of Ships” data published for the Bab el-Mandeb Strait at https://portwatch.imf.org/pages/6b1814d64903461b98144a6cc25eb79c.
