## Prediction

Within seven days, the U.S. and select partners are likely to modestly increase naval and airborne ISR presence near the Strait of Hormuz and adjust rules of engagement to more assertively accompany vulnerable tankers, but they will stop short of declaring a formal convoy or exclusion-zone regime. These deployments will be framed as protective and grounded in freedom-of-navigation principles. Iran will respond with additional naval and IRGC fast-boat patrols, close shadowing, and rhetoric, raising the probability of non-kinetic confrontations like laser illumination and radio challenges. A contrarian scenario would see an incident—such as a boarded or detained tanker—forcing a faster shift to formal convoys.

## Drivers

- Iran’s formal claims to military control and supervision over Hormuz entrances
- Ongoing U.S. interdictions of Iranian-linked tankers and coercive blockade diplomacy trend
- Past U.S.–Iran naval posture after tanker seizures and attacks
