Ongoing U.S.-Iran hostilities, including renewed attacks on commercial vessels in the Strait of Hormuz and the reimposition of a U.S. naval blockade, have kept daily transits at lows of 5–12 vessels since early August 2026, far below the pre-February 2026 average exceeding 130. A June memorandum of understanding that briefly eased restrictions collapsed in July after Iranian strikes on ships and disputes over routing and fees, with subsequent diplomatic efforts stalling amid mutual accusations and threats. These developments sustain elevated risk perceptions among shipowners, directly supporting the 67.5% trader consensus that traffic volumes—defined by a seven-day average above 60 transits—will not normalize by December 31. Persistent naval posturing and unresolved control negotiations over the chokepoint reinforce expectations of continued disruption through year-end.

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 December 31, 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.
