## Prediction

Within the next 24 hours, Iranian IRGC Navy and paramilitary units are likely to conduct aggressive hailing, boarding attempts, or close shadowing of commercial tankers in or near the Strait of Hormuz, short of outright seizure. The objective will be to demonstrate that shipping now moves under “Iranian arrangements” while avoiding an immediate shooting exchange with US or allied escorts. This will heighten crew anxiety, increase near‑miss risk, and force Western navies to reposition assets closer to high‑traffic lanes, raising miscalculation odds. Confirmation would include AIS anomalies, rerouting notices, or public complaints by shipping firms of interference; a contrary signal would be explicit IRGC orders to stand down or visible cooperative escorts through the Strait.

## Drivers

- Iran’s parliament speaker threatening war and asserting control over Hormuz transit terms
- Declared halt to further US–Iran talks until MOU implementation
- Historical pattern of boarding and harassment operations during periods of tension
