Iranian Naval Proxies and Mines Threaten to Turn Hormuz Into Semi-Denied Zone
Theater: Strait of Hormuz
Time horizon: 7d

Moderate confidence (65%)
Risk direction: escalatory · Impact: CRITICAL
Full prediction
Within seven days, Iran is likely to supplement direct missile attacks with proxy-operated fast boats, naval drones, and limited mine-laying to create a semi-denied environment in parts of Hormuz without declaring a formal closure. These tactics will aim to raise transit risks selectively for U.S.-linked and Gulf-aligned tankers, while preserving some plausible deniability. U.S. and allied navies will respond with aggressive mine countermeasures and expanded ISR, raising the likelihood of close-quarter incidents and accidental engagements. Confirmation would include sightings or interdictions of suspected mine-layers, increased reports of naval drones, and partial route closures by commercial operators; a sustained week with no further incidents and normal AIS patterns through Hormuz would undermine this forecast.
