Hormuz Naval Standoff Likely to Harden Into De Facto Blockade With Escorted Convoys
Theater: Strait of Hormuz

Moderate confidence (72%)
Risk direction: escalatory · Impact: CRITICAL
Full prediction
Over the next week, the combination of Iranian threats and repeated ship attacks is likely to solidify into a de facto partial blockade of Hormuz, with only naval-escorted or state-chartered convoys transiting. Western and Gulf navies will increase presence, establish protected corridors, and possibly conduct limited strikes on suspected launch sites if casualties mount. This will embed higher military operating tempo and accident risk, particularly involving IRGC small boats and drones shadowing convoys. Confirmation would be formal escort announcements by US or allied navies and further insurance surcharges tied to escorted vs. non-escorted ships; a rapid diplomatic breakthrough on sanctions relief would challenge this forecast.
