Ongoing U.S.-Iran hostilities, now in their sixth month since late February, continue to suppress commercial transits through the Strait of Hormuz to roughly 4-7% of pre-war volumes, with recent data showing only six vessels on September 9 versus a typical 125 daily. Escalating tanker attacks on September 9, including U.S. strikes on five Iranian carriers and Iranian retaliation against multiple ships, have pushed Brent crude above $100 per barrel and kept war-risk insurance premiums at extreme multiples, deterring operators. The market-implied 98.4% probability of "No" aggregates trader consensus that these security, insurance, and blockade dynamics preclude normalization by September 30. Tail risks include a rapid ceasefire or verified de-escalation corridor that could accelerate recovery, though current kinetic exchanges and expanded exclusion zones make such shifts improbable in the near term.

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 30, 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.
