## Prediction

Within 24 hours, at least one commercial vessel perceived as Israel-linked is likely to report boarding attempts, diversion orders, or close-quarters harassment by IRGC Navy assets in or near the Strait of Hormuz. Even if no ship is seized or damaged, such contact would operationalize Iran’s declared policy of blocking Israel-associated traffic and contradict US claims that traffic is flowing normally. This will push shipowners to avoid the chokepoint, drive up war-risk premiums, and increase the chances of miscalculation with US or allied naval escorts. Confirmation would be AIS anomalies, crew reports, or video of IRGC units confronting specific tankers; denial would be uninterrupted passage of Israel-linked ships with no credible harassment reports.

## Drivers

- IRGC public reaffirmation of Hormuz closure to 'Zionist entity'-linked vessels
- Multiple reports that Iran has re-ordered closure of the Strait
- Pattern of previous Iranian harassment and seizures in Hormuz
- Israeli strikes in Lebanon raising Tehran’s need to demonstrate resolve
