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.Recent Houthi attacks, including fatal strikes on August 11, and the July 20 Saudi shipping blockade have sustained elevated war-risk premiums above 1% of vessel value, yet Bab el-Mandeb transits proved resilient with weekly totals rising to 254 for 10–16 August from 238 the prior week. Daily crossings averaged 36–41 vessels amid a mix of sanctioned, shadow-fleet, and compliant traffic, reflecting selective avoidance by major container lines alongside continued tanker movements of Saudi crude from Yanbu and Russian volumes to Asia. These volumes, supported by carve-outs for certain flag states and limited rerouting to the Cape or Suez, position 200+ transits as the consensus outcome for the week of August 17 while allowing for downside risk if attacks intensify or insurance markets tighten further.
