## Prediction

Over the next 30 days, sustained IRGC enforcement of transit permissions and potential armed escorts by US and GCC navies in Hormuz will significantly raise the likelihood of a direct US–IRGC naval skirmish—such as an exchange of warning fire, disabling shots on small craft, or aerial engagement. A trigger could be IRGC boarding of a US-linked tanker or an aggressive maneuver that Washington interprets as a direct threat to its vessels or aircraft. Even a brief skirmish would spike oil prices, prompt emergency diplomatic efforts, and could accelerate US congressional moves on Iran sanctions and force posture. Confirmation would be reports of close intercepts, near-collisions, or shots fired in contested interactions; denial would be a negotiated set of navigation rules or quiet Iranian pullback from the most provocative tactics.

## Drivers

- Live-fire IRGC enforcement on a cargo ship and ongoing tanker turnbacks
- Iran’s monetization push raising strategic stakes beyond symbolism
- Anticipated US and GCC naval escorts crowded into a narrow chokepoint
- Historical pattern of incident-prone US–IRGC interactions in the Gulf
