Ongoing Iran-US tensions and Iranian enforcement actions since the February 2026 closure declaration have kept commercial traffic through the Strait of Hormuz at minimal levels for 178 days, with daily transits often below 10 vessels versus a pre-crisis average near 85. Iran maintains military control, blacklisting 45 tankers in late August and threatening fines, detention, or confiscation for rule violations, while war-risk insurance premiums remain around 40 times normal, deterring most operators. Recent Iran-Oman talks on a temporary navigational corridor and mine-clearing have not altered Tehran's position that the waterway stays militarily closed absent broader US concessions. Low-volume days with zero outbound movements have already occurred amid these pressures, alongside US sanctions and naval measures. Upcoming diplomatic or enforcement developments could shift volumes, but current barriers continue to constrain reliable passage.

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.
