Ongoing US-Iran hostilities and Iranian efforts to control transit routes have kept Strait of Hormuz traffic severely restricted through mid-September 2026, underpinning the 100% market-implied probability that volumes failed to normalize by September 15. Pre-war daily transits averaged roughly 130 vessels, yet recent data show only 14 crossings over a weekend in late September, with flows remaining far below normal amid elevated risks, selective routing, and threats from Tehran. This reflects sustained sanctions pressure, intermittent strikes, and insurer caution that have capped commercial activity despite temporary ceasefire attempts earlier in the year. While a sudden de-escalation or verified safe-passage protocol could theoretically alter conditions, the entrenched conflict dynamics and data through September 21 make reversal of the observed shortfall highly improbable.

Daily 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 IMF Portwatch publishes a 7-day moving average of transit calls equal to or above the specified level, or once data has been published for the final date in the specified period and no such value has been published. If no data has been published for the final date of the specified period within 14 calendar days (ET) after the end of that period, this market will resolve based on data published up to that point.
Revisions to previously published data points made within this market’s timeframe will be considered. However, they will not disqualify a previously published data point from qualifying. Revisions to previously published data points after data is published for September 15, 2026, however, will not be considered.
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.
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.
