US and Iran Naval Forces Shadow Hormuz Shipping as Legal Claim Sparks Standoff
Theater: Strait of Hormuz
Time horizon: 24h

Moderate confidence (70%)
Risk direction: escalatory · Impact: HIGH
Full prediction
Within 24 hours, US and Iranian naval units are likely to increase close-in shadowing and querying of commercial vessels transiting the Strait of Hormuz, without crossing into direct kinetic engagement. Commercial tankers and LNG carriers will experience tighter escort patterns, more hails, and short, tense course alterations near US and Iranian patrol craft. This matters because a single misinterpreted maneuver or warning shot could rapidly escalate into a limited firefight that would spike crude prices and trigger emergency alliance consultations. Confirmation would include AIS gaps, reports of close approaches or illumination of ships by fire-control radar; disconfirmation would be explicit US or Iranian orders to maintain distance and deconfliction hotlines being publicized and used.
