## Prediction

Over the next 30 days, Iran’s move to impose Hormuz transit fees and its ‘act of war’ rhetoric will drive increased IRGC Navy patrols and boardings near the strait, while the US and partners boost naval presence and aerial surveillance. The intensified shadowing will significantly raise the probability of a limited incident—such as a boarding standoff, warning shots, or temporary tanker seizure—though both sides will initially aim to localize any clash. Even a minor confrontation would spike energy prices, trigger rapid coalition consultations, and test Gulf states’ crisis-management capacity. Confirmation would be multiple close encounters, harassment reports, or warning shots within the strait; denial would involve diplomatic de-escalation and a stable or reduced military footprint.

## Drivers

- Iranian parliament approval of Hormuz transit fees, weaponizing legal control over the chokepoint
- Explicit Iranian threats to halt all Persian Gulf oil exports if sanctions persist
- CENTCOM assessment of elevated threat and realignment of Gulf security around the Hormuz crisis
