Ongoing US-Iran tensions stemming from the February 2026 conflict and subsequent April 8 ceasefire have kept commercial traffic through the Strait of Hormuz at a small fraction of normal volumes into late May. Iranian naval controls, requirements for vessels to use alternate routes in its territorial waters, elevated insurance costs, and persistent rerouting around Africa have sustained the disruption despite the truce. Traders assign near-certain probability to no return to pre-crisis levels by month-end because these security, logistical, and financial barriers have shown little improvement. Potential shifts could still arise from a comprehensive bilateral agreement addressing navigation rights or rapid de-escalation signals from key actors, though such developments had not materialized by the resolution deadline.

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 May 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.
