Tensions in the Strait of Hormuz remain elevated following the collapse of the June 2026 U.S.-Iran memorandum of understanding, which briefly allowed limited commercial transits after months of conflict that began in late February. Iranian forces have conducted repeated strikes on vessels using unauthorized routes, issued turn-back orders, and asserted control over all lanes, while the United States reimposed a naval blockade and conducted airstrikes on Iranian military targets in July. Ongoing risks from mines, drone and missile attacks, and sanctions have kept overall traffic far below pre-conflict levels of roughly 130 vessels per day, with periods of sharply reduced or functionally suspended outbound tanker movements. Traders monitor any escalation in kinetic exchanges or diplomatic signals that could produce a complete daily shutdown of transits.

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.
