US–Iran Confrontation Evolves Into Sustained Maritime And Missile Shadow War Around Hormuz
Theater: Strait of Hormuz
Time horizon: 30d

Moderate confidence (70%)
Risk direction: escalatory · Impact: CRITICAL
Full prediction
Over the next 30 days, the confrontation between the US and Iran is likely to harden into a sustained pattern of maritime harassment, targeted vessel seizures, and episodic missile and drone incidents in and around the Strait of Hormuz, short of full-scale war. Both sides will calibrate actions to avoid large-scale casualties while seeking leverage: Iran through pressure on shipping and proxy actions, the US through strikes on IRGC assets and intensified escorts. This shadow war will normalize elevated military risk in the world’s key oil chokepoint, complicating commercial planning and increasing the likelihood that a miscalculated engagement could suddenly escalate into broader regional conflict. Confirmation would be multiple documented harassment or seizure incidents and at least one additional missile or drone exchange; denial would be a negotiated de-escalation or verifiable stand-down in operations.
