Ongoing US-Iran tensions since February 2026, including naval blockades, IRGC route enforcement, drone and missile incidents, and disputes over Iranian versus Omani transit corridors, have driven Strait of Hormuz traffic to multi-month lows. Recent AIS and PortWatch data show daily transits often in single digits or low teens, with widespread dark sailing, elevated war-risk premiums, and selective vessel turnbacks, yet limited commercial crossings persist through approved or covert lanes. This environment sustains trader consensus that a complete zero-transit day remains improbable in the near term absent full escalation or formal closure. Key near-term catalysts include any breakdown in US-Iran diplomacy, further attacks on shipping, or shifts in blockade enforcement that could alter daily volumes tracked by IMF PortWatch.

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.
