Ongoing geopolitical tensions and active military exchanges between U.S. and Iranian forces have kept commercial traffic through the Strait of Hormuz at a fraction of pre-crisis norms of roughly 85 daily transits, driving the market-implied probability toward the 20-39 ship range for the week of August 31. Daily counts from IMF PortWatch and Kpler data remained in the low single digits through late August, with just six total transits recorded on August 30 amid mine threats, tanker attacks, Iranian vessel blacklists, and elevated war-risk insurance premiums that deter most operators. Recent U.S. strikes on Iranian positions near the strait and retaliatory missile activity have sustained route uncertainty and prompted many vessels to go AIS-dark or reroute entirely, while limited corridor agreements with Oman have produced only marginal, short-lived gains. These factors align with the 70% implied odds on 20-39 transits, though persistently suppressed volumes leave room for a sub-20 outcome if enforcement tightens further before resolution.

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.
