Persistent U.S.-Iran military tensions and an active naval blockade have kept commercial traffic through the Strait of Hormuz at roughly 1-2% of pre-conflict levels as of late August 2026, with daily transits near one vessel versus a normal 60-73. War-risk insurance premiums remain prohibitive for most operators, while repeated ship attacks through mid-August and unresolved security concerns such as potential mines sustain the disruption. This environment underpins the 98.6% market-implied probability that traffic will not normalize by September 15. The near-certain trader consensus reflects the absence of credible de-escalation signals or infrastructure recovery timelines. Tail-risk scenarios include a rapid diplomatic breakthrough or ceasefire that could enable swift clearance operations and insurance normalization, though current momentum points against such developments materializing in the next three weeks.

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.
