## Prediction

Within seven days, Iran’s IRGC Navy or allied forces are likely to shadow, harass, or attempt to board at least one tanker associated with US-aligned or UAE-linked interests transiting near Hormuz to assert leverage without immediately triggering full war. The action would aim to demonstrate that Iran can still control or disrupt flows despite UAE’s trade freeze and Western naval presence. Evidence would be AIS anomalies, shipowner or state reports of close IRGC approaches, or an actual boarding captured on video; non-materialization would be more plausible if a mediated de-escalation framework and safety corridor are quickly agreed.

## Drivers

- Iranian discussion of striking broader infrastructure (including Hormuz subsea cables)
- UAE’s full suspension of trade and finance with Iran tightening economic pressure
- Historic Iranian pattern of tanker harassment in crises (Stena Impero precedent)
- Exploding Hormuz freight rates suggesting markets already price in seizure risk
