Ongoing Iran conflict since February 2026 has severely restricted Strait of Hormuz transits to single-digit daily levels—often 2-15 commodity vessels versus pre-crisis norms above 85—through Iranian enforcement, IRGC warnings, blacklisting of 45 tankers in late August, mine risks, and attacks including a projectile strike on an Aframax tanker on August 24. Most movements occur via the northern Iranian-approved corridor or as dark transits, with war-risk premiums at 40x normal deterring operators and stranding thousands of seafarers. Recent Iran-Oman revenue and lane talks on August 26 offer limited de-escalation signals amid U.S. sanctions and naval facilitation of select passages, while persistent kinetic incidents and insurance barriers sustain trader focus on whether any full zero-transit day occurs before the market deadline.

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 IMF PortWatch publishes a daily number of transit calls equal to 0, or once complete data has been published for the specified period without such a publication. If complete data for the specified period has not been published within 28 calendar days of the end of the specified period, this market will resolve based on 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. Revisions to previously published data points made within this market’s timeframe will be considered. However, they will not disqualify a previously published data point from qualifying except in the case of data integrity issues.
The resolution source for this market will be IMF PortWatch, specifically the transit calls data published for the Strait of Hormuz at https://portwatch.imf.org/pages/cb5856222a5b4105adc6ee7e880a1730, both in the chart and through downloadable files.
