Protracted U.S.–IRGC Naval Skirmishing Turns Hormuz Into Semi-Permanent Exclusion Zone
Theater: Strait of Hormuz

Moderate confidence (70%)
Risk direction: escalatory · Impact: CRITICAL
Executive summary
Over the next 7 days, repeated U.S.–IRGC naval standoffs, drone overflights, and episodic attacks will likely transform Hormuz into a de facto semi-closed exclusion zone for most commercial operators. Only state-protected convoys or risk-tolerant shippers will attempt passage, sharply reducing throughput and raising the chances of a fatal incident that forces one side into a rapid escalation step. The U.S. will intensify ISR and electronic surveillance while Iran disperses naval assets to smaller inlets and islands, entrenching the crisis rather than resolving it. Confirmation would be a sustained drop in AIS-tracked tanker counts through Hormuz and recurring small clashes; denial would be a visible negotiated traffic regime with escorts agreed…
