Full prediction

Within 24 hours, Iran is likely to conduct limited missile, drone, or fast-boat harassment against commercial shipping near the Strait of Hormuz to reinforce its demand that negotiations be tied to reopening the waterway. The main targets would be tankers with perceived U.S./EU-linked cargoes or Gulf-ally flags, avoiding mass casualties but creating high-visibility images of risk. This would tighten naval operating rules, trigger insurance surcharges, and increase the chance of miscalculation with U.S. or GCC naval escorts. Confirmation would be any recorded approach, warning shots, or strike attempt attributed to IRGC Navy units; denial would be a visible pause in Iranian kinetic activity combined with backchannel signaling of restraint.
