**Persistent Houthi threats and targeted attacks on Saudi-linked tankers, combined with elevated war-risk premiums, continue to suppress traffic through the Bab el-Mandeb Strait.** Recent July 2026 blockade declarations and strikes have driven compliant transits toward 20–35 vessels per day in monitored periods, well below 2023 peaks near 70, with shadow-fleet and dark activity filling gaps amid Hormuz disruptions. These dynamics position the <25 and 25–29 bins as market leaders, reflecting trader consensus on sustained rerouting incentives and selective enforcement risks into late September. Upcoming catalysts include any escalation in Houthi ground operations near the strait or shifts in carrier routing decisions, which could further compress volumes or support modest recovery if premiums ease.

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 the 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.
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.
