Ongoing U.S.-Iran hostilities, including a naval blockade and repeated attacks on vessels through mid-August 2026, have kept Strait of Hormuz transits at a fraction of pre-conflict levels since late February, with war-risk insurance premiums rendering most commercial voyages uneconomic. Recent incidents, such as strikes on tankers and bulk carriers in early-to-mid August, alongside stalled ceasefire talks, reinforce trader consensus that normalization remains improbable within the next three weeks. Market-implied odds for "No" at 98.6% reflect the structural barriers of threat clearance, backlog resolution, and premium normalization, which historically require months even after de-escalation. Tail risks include an unexpected diplomatic breakthrough or rapid threat abatement, though current dynamics suggest these would need substantial policy shifts to alter the near-term trajectory.

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.
