US Naval Boardings of Iran-Linked Tankers Intensify Around Closed Strait of Hormuz
Theater: Persian Gulf
Time horizon: 24h

Moderate confidence (70%)
Risk direction: escalatory · Impact: HIGH
Full prediction
Within 24 hours, CENTCOM is likely to increase disabling and boarding operations against Iran-linked tankers and support vessels in the Gulf approaches to Hormuz. Impacted actors include Iranian state shipping entities, front companies, and third-country flag operators carrying Iranian crude or condensate. This will raise immediate operational risk for vessels transiting near the strait, potentially forcing diversions via alternative terminals and amplifying insurance surcharges. Confirmation would come via public US Navy statements, AIS-tracked diversions, and industry advisories flagging specific hulls targeted; a denial scenario would be an explicit White House message constraining the blockade to minimal interdictions.
