Iranian Anti-Ship Missile Harassment Keeps Effective Hormuz Closure Through Next 24 Hours

Risk direction: escalatory · Impact: CRITICAL
Full prediction
Iranian forces are likely to conduct at least limited additional missile launches or fire-control lock-ons against merchant shipping in or near the Strait of Hormuz over the next 24 hours, sustaining a de facto closure for non‑escorted traffic. Commercial tankers and bulk carriers will either delay transit, divert, or sail under heightened risk, while U.S. and allied naval units increase defensive postures and intercept preparations. This preserves a live-fire environment that deters normal traffic and raises miscalculation risk between Iranian coastal batteries and U.S. warships. Confirmation would be additional launch reports, radar lock incidents, or formal navigation warnings; denial would be a verifiable, sustained halt in Iranian launches and a visible resumption of routine commercial transits.
