Recent Houthi attacks on Saudi oil installations along the Red Sea coast and the group's maritime embargo threats sharply curtailed commercial traffic through the Bab el-Mandeb Strait in late July 2026. Shipping data from Kpler showed daily commodity vessel transits dropping to as low as 11 on July 27—the lowest in months—with weekly averages near 30 vessels amid widespread rerouting by tankers and bulk carriers. This geopolitical disruption, layered on persistent regional tensions, produced a clear market-implied range of 200-219 transits for the week, reflecting traders' assessment of verified volume declines rather than baseline seasonal norms. A rapid de-escalation or confirmed rebound in daily crossings above 40 could still pressure the outcome if post-week revisions alter final tallies, though current positioning embeds strong confidence in the observed suppression.

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.
