## Prediction

Within 24 hours, Iran’s IRGC Navy will visibly step up inspections, close shadowing, or radio challenges against vessels not adhering to its preferred routing in the Strait of Hormuz, without yet seizing a flagship Western-flag tanker. This will create immediate tension for shipmasters and insurers as companies reassess whether to accept IRGC pilotage or routing guidance. The risk is a miscalculation—an over-aggressive boarding or warning shot—triggering U.S. or allied escort operations that militarize routine transits. Confirmation would be multiple, corroborated reports of IRGC small craft or helicopters challenging ships near Iranian-claimed lanes; denial would be a quiet transit day with no publicized harassment incidents after Tehran’s warnings.

## Drivers

- IRGC statement calling uncoordinated Hormuz routes 'dangerous and prohibited'
- U.S. public rejection of Iranian control and any fee regime
- Historical IRGC pattern of incremental harassment before major seizures
