Ongoing US-Iran conflict and dual blockades have compressed Strait of Hormuz transits to multi-month lows, with Kpler data showing daily commodity vessel crossings averaging 10–15 and frequently dipping to 2–5 in recent days—well below pre-crisis levels of roughly 95. This environment of heightened enforcement, dark (AIS-off) routing, mine risks, and Iranian blacklisting of non-compliant tankers drives the 78.5% market-implied probability for 25–49 weekly transits, reflecting trader consensus on sustained suppression amid limited facilitation via northern corridors. Recent weekend figures of 13–17 crossings and Monday’s two-tanker tally reinforce positioning below 50, while any diplomatic easing or expanded US-escorted southern routes could lift volumes toward the thinner 50–74 band priced at just 4%.

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.
