Heightened Naval-Air Posture But No Full Kinetic Closure of the Strait of Hormuz
Theater: Strait of Hormuz
Time horizon: 24h

Moderate confidence (70%)
Risk direction: escalatory · Impact: HIGH
Executive summary
Over the next 24 hours, Iran and the US/UK-led coalition are likely to further increase surveillance flights, naval patrols, and rules-of-engagement readiness in and around the Strait of Hormuz, but will stop short of attempting an outright closure or large-scale interdictions. Iran will continue to assert sovereign control and potential fees, while Western forces conduct visible escort missions and exercises to signal deterrence. Isolated close approaches, lasing incidents, or drone overflights are probable and may cause temporary ship diversions. However, both sides currently have incentives to avoid a trigger incident while coercive bargaining and Chinese pressure on Tehran continue.
Key indicators we're watching
