Ongoing U.S.-Iran tensions since late February 2026 have kept commercial traffic through the Strait of Hormuz—a chokepoint handling roughly 20% of global seaborne oil—at a fraction of the pre-crisis average of about 100 vessels daily. Recent data from Kpler and Lloyd’s List show 5–10 transits per day in late May and early June, supported by limited Iranian permits, U.S. naval coordination of roughly 70 “dark” passages over three weeks, and modest upticks from negotiated lanes. Brent crude remains elevated near $97 amid supply risks and higher insurance costs, with over 600 vessels still idled in the Gulf. Traders are watching early-June IMF PortWatch and Kpler reports plus any diplomatic progress for signs of sustained normalization ahead of the June 30 market 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.
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 a qualifying figure has been finalized or once all relevant data has been finalized. If the data for the final date of the specified timeframe has not been finalized by the end of the third calendar day (ET) after the day on which such data is first released, this market will resolve based on data published up to that point. Additionally, if not all relevant data has been released and finalized within 14 calendar days of the end of the specified period, this market will resolve based on 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.
