**Ongoing Houthi attacks and the Saudi maritime blockade declared in July 2026 have kept Bab el-Mandeb transit volumes subdued and volatile, with daily crossings fluctuating between roughly 30–40 vessels amid elevated war-risk premiums, shadow-fleet activity, and dark transits.** Recent data show stabilization near post-blockade lows, with 61 transits recorded over 48 hours ending August 31 and weekly aggregates in the 250–300 range earlier in August before easing. Mainstream tanker flows remain most constrained, while bulkers and some container traffic show modest resilience, creating the tight clustering of market-implied odds around the 190–230 buckets. Traders are weighing whether renewed threats or improved visibility will push counts higher or sustain the current compressed range through resolution.

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.
