Heightened security risks from the ongoing Iran conflict, including IRGC enforcement actions, mine threats, and attacks on vessels such as the Kuwaiti tanker Al Salam II on August 26, combined with war-risk insurance premiums at 40 times normal levels, have driven commercial transits through the Strait of Hormuz to just 4% of pre-crisis norms. Recent IMF PortWatch data recorded only three transits on August 23 and single-digit daily volumes in the preceding days, positioning the 25-49 weekly outcome as the dominant market-implied probability at 89%. Major carriers continue rerouting, while limited dark-fleet activity and U.S. facilitation have not materially lifted overall throughput.

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.
