Iranian Missile or Drone Harassment of Gulf Shipping Likely After US Tanker Strikes
Theater: Strait of Hormuz
Time horizon: 24h

Moderate confidence (68%)
Risk direction: escalatory · Impact: CRITICAL
Full prediction
Within 24 hours, Iran or IRGC-linked units are likely to conduct missile, drone, or fast-boat harassment against commercial shipping or naval escorts near the Strait of Hormuz in retaliation for US strikes on Iranian state tankers and IRGC sites. The most exposed will be tankers with US, UK, or Gulf charter ties, and vessels transiting close to Iranian territorial waters, raising operational risk for shipowners and flag states. A successful hit or forced diversion of a tanker would widen the escalation spiral and justify further US or coalition protective deployments, increasing the probability of miscalculation at sea. Confirmation would be AIS anomalies, forced boardings, or reported strikes on non-Iranian commercial vessels; denial would be visible Iranian restraint combined with de-escalatory messaging and continued focus only on US military targets.
