Persistent geopolitical tensions and active military posturing between the US and Iran continue to constrain commercial vessel movements through the Strait of Hormuz, the critical chokepoint handling roughly one-quarter of global oil flows. Recent attacks on merchant ships in early August, combined with US enforcement of a naval presence and Iranian assertions of transit controls, have kept daily crossings at sharply reduced levels of 8–16 vessels, well below the pre-crisis average of 130-plus. Elevated war-risk insurance premiums, rerouting incentives, and uncertainty over Oman-mediated talks have further suppressed non-sanctioned traffic, supporting trader consensus around minimal end-August averages. Key near-term catalysts include any de-escalation signals or renewed strikes that could alter implied probabilities ahead of month-end resolution.

If the reported value falls exactly between two brackets, this market will resolve to the higher range bracket.
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.
Data for a specific date must be finalized before it is considered for this market (namely, once the next date's data point is available, the previous one is finalized).
This market will resolve as soon as the relevant data has been finalized. If the data for the specified date has not been finalized by the end of the third calendar day (ET) after the day on which such data is released, this market will resolve based on data published up to that point. Additionally, if the relevant data is not released and finalized 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 the applicable resolution time 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.
