This market will resolve according to the 7-day moving average of transit calls (“Arrivals of Ships”) for the Strait of Hormuz that IMF Portwatch reports for March 31, 2026. 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 data for March 31, 2026 has been published. If no data for March 31, 2026 has been published by April 14, 2026, 11:59 PM ET, this market will resolve based on data for the most recent date prior to March 31, 2026 for which data is available. This market will resolve based on the first publication of data for March 31, 2026. Any subsequent revisions will not be considered. If the reported value falls exactly between two brackets, this market will resolve to the higher range bracket. 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.Iran's de facto blockade of the Strait of Hormuz amid the ongoing Mideast war since late February has driven trader consensus to 97.8% on an average of 0-10 ships daily at month-end, reflecting maritime intelligence data showing transits plummeting from a pre-conflict 138 vessels per day to single digits. Windward and UANI reports confirm critically low activity, with just 11 vessels on March 28, 3-4 on March 27, and 7 total over March 25-26, as Iran vets non-hostile ships via a selective system while ghost fleet tankers make intermittent dark transits. This commanding position holds despite minor upticks, sustained by escalation risks and loitering congestion. Scenarios like a U.S.-brokered deal for 20 additional oil ships or naval escorts could challenge it by boosting volumes into double digits.
