Heightened geopolitical risks from the Houthis' July 2026 maritime blockade of Saudi shipping and subsequent attacks, including the recent strike on the Tihamah cargo vessel, have compressed daily transits through the Bab el-Mandeb Strait to around 30-40 vessels amid elevated insurance premiums and rerouting incentives. Trader consensus reflected in the 44.8% implied probability for an average below 25 by month-end prices in the persistent threat environment, with Hormuz disruptions further limiting alternative flows and sustaining downward pressure on volumes. Recent weekly data showing stabilization near suppressed levels, rather than recovery, reinforces this positioning ahead of the imminent resolution window.

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.
