Iranian Naval and Missile Posture in Persian Gulf Shifts to Pre-Exclusion Standoff
Theater: Persian Gulf
Time horizon: 7d

Moderate confidence (60%)
Risk direction: escalatory · Impact: CRITICAL
Full prediction
Within seven days, Iran is likely to increase IRGC-N naval patrol density, conduct missile drills, and issue more detailed navigation advisories that stop short of a formal exclusion zone but create a de facto standoff environment in the central and northern Gulf. US and allied naval assets will respond with more visible escorts and surveillance, increasing the frequency of close-quarter interactions. While both sides will initially avoid live fire, the tactical risk of collision or miscalculation will rise sharply. Confirmation would be satellite and AIS evidence of reinforced Iranian deployments and new navigation 'warnings'; denial would involve Tehran walking back its rhetoric and keeping its Gulf posture at current levels.
