Ongoing military tensions stemming from U.S.-Israeli strikes on Iran in February 2026 triggered Iranian restrictions and a U.S. naval presence, sharply reducing Strait of Hormuz transits through attacks on vessels, insurance cancellations, and commercial rerouting. Iranian authorities have enforced selective closures, toll proposals, and bans targeting ships linked to the U.S. and Israel, while periodic diplomatic efforts for reopenings have collapsed amid renewed incidents. As of mid-August 2026, traffic remains near standstill with coercive instructions, UAV strikes, and enforcement actions keeping volumes far below baseline. Key variables for traders include the durability of Iranian control, any U.S. or multilateral de-escalation agreements, naval escort dynamics, and scheduled diplomatic or domestic political timelines that could alter enforcement or risk perceptions before the market resolution date.

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.
