## Prediction

Within seven days, Iran’s IRGC Navy is likely to probe the U.S. blockade by flying UAVs close to U.S. ships, conducting high-speed passes with fast boats, and shadowing commercial tankers transiting the cleared lanes without engaging in outright attacks. These actions will aim to challenge U.S. control narratives, gather ISR, and rally domestic opinion without crossing a clear red line that could trigger a major U.S. strike. The pattern will raise near-miss risk and keep insurers pricing in elevated operational hazard for Gulf shipping. Confirmation would be public or leaked reports of close encounters, warning shots, or drone interceptions; denial would be an unexpectedly quiet IRGC maritime posture emphasizing restraint.

## Drivers

- Hybrid maritime brinkmanship around Hormuz identified as an escalation trend
- U.S. shift from mine clearance to long-haul blockade posture at Iran’s main export artery
- Trump’s maximalist territorial rhetoric, increasing Iranian pressure to respond symbolically
