Limited US–Iran Naval Skirmishes Threaten Misfire in Strait of Hormuz

Moderate confidence (60%)
Risk direction: escalatory · Impact: HIGH
Full prediction
Over the next 24 hours, close-proximity maneuvers and warning shots between US naval units and IRGC or proxy fast boats are likely to occur in the Strait of Hormuz, though both sides will initially avoid mass-casualty engagement. The recent US strike on the Iran-bound Vela Nova and visible oil spill near Qeshm increase the chance that an interception or boarding attempt escalates into a brief exchange of fire. This would not yet close Hormuz but would sharply raise near-term risk perceptions and provide Tehran domestic justification for tit-for-tat harassment of tankers. Confirmation would be credible reports of warning shots, attempted boardings, or collision incidents; denial would be explicit de-escalatory rules-of-engagement messaging or visible stand-off distances maintained by both navies.
