Iranian Anti-Ship Missile or Drone Strike on Gulf Commercial Vessel Likely Within a Week
Theater: Strait of Hormuz
Time horizon: 7d

Moderate confidence (60%)
Risk direction: escalatory · Impact: CRITICAL
Executive summary
Within seven days, Iran or aligned forces are likely to attempt at least one anti-ship missile, drone, or fast-boat explosive attack on a commercial vessel linked to US, UK, or Gulf allies in or near Hormuz. The attack will likely aim for disabling damage rather than mass casualties, testing US claims of chokepoint control and raising costs for the de facto blockade. Success would meaningfully increase war-risk premiums, pressure global shipping flows, and force additional NATO naval deployments. Confirmation would be damage or near-miss reports and IRGC or proxy messaging about 'breaking the blockade'; visible Iranian restraint paired with emerging diplomatic channels would moderate this risk.
