## Prediction

Over the next 30 days, the US–Iran confrontation is likely to solidify into a sustained maritime blockade-and-counterpressure dynamic, featuring recurring boardings, diversions, and occasional low-intensity clashes but avoiding full-scale war. Even if a partial diplomatic arrangement emerges, Washington will probably maintain significant constraints on Iranian oil exports, justified by compliance verification and regional security. Iran, in turn, will deploy asymmetric tactics—fast boats, drones, and proxies—to harass but not catastrophically damage commercial shipping and US assets. This prolonged standoff will normalize higher military presence and miscalculation risk in the Gulf.

## Drivers

- Emerging trend of coercive maritime blockade diplomacy in the US–Iran confrontation
- Repeated US boardings and US rhetoric about blockade enforcement
- Iran’s legal framing of Hormuz sovereignty and threats of broader war if pressured
