## Prediction

Over the next month, even if a high-level MoU is maintained, Iran’s IRGC Navy is likely to normalize a pattern of intermittent vessel boardings, detentions, and close harassment of tankers near the Strait of Hormuz, using the closure narrative as a standing leverage tool. These actions will be calibrated to avoid direct clashes with US or allied warships but will create a chronic risk environment for commercial shipping. The result will be de facto Iranian veto power over some traffic and a persistent sense of vulnerability for Gulf exporters and global energy importers. Confirmation would be multiple additional harassment incidents and temporary detentions in the area; denial would be a sustained, verifiable period of safe and interference-free passage after a formal reopening declaration.

## Drivers

- Persistent Iranian media narrative that Hormuz remains closed with permits withheld
- Emerging trend: Hormuz crisis as structured bargaining chip in US–Iran negotiations
- IRGC history of ship harassment and seizures in previous crises
