US expands strikes and enforces blockade; Iran strikes Gulf bases; Strait of Hormuz transits cut ~50%
Very likely (75-90%) that US forces expanded strike operations inside Iran on 16-17 July 2026 and are enforcing a maritime blockade that has reduced insured commercial transits through the southern Strait of Hormuz by roughly 50%; Confidence: Moderate, corroborated by US Central Command and Department of Defense statements, Kpler and Vortexa flow data, and an IMO advisory, but reduced by inconsistent casualty reporting and several single-source Iranian state media claims.
