Heightened geopolitical risks from the US-Iran conflict, including a reimposed blockade on Iranian exports and recent strikes on tankers such as the EL GAIA on September 13, have suppressed visible commercial transits through the Strait of Hormuz to single-digit daily levels. Shipping data from sources like IMF PortWatch and Kpler show roughly 5–8 AIS-tracked crossings per day in the week of September 14, well below the pre-crisis baseline near 85, amid elevated war-risk insurance premiums and carrier rerouting. The close contest between 20–24 and 25–29 total transits reflects uncertainty over dark-ship movements, US-facilitated southern-route activity, and inclusion criteria for facilitated versus AIS-derived counts. Key swing factors include weekend fluctuations and any last-minute revisions to preliminary tracking data.

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 all relevant data has been published. If the relevant data is not published within 14 calendar days of the specified date, this market will resolve based on the most recent 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.
Only revisions to previously published data points made before all relevant data has been published will be considered.
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.
