Risk direction: escalatory · Impact: HIGH
Executive summary
In the next 24 hours, Iran is likely to conduct at least one additional harassment or near-miss incident against commercial vessels—radar locking, approach by fast boats, drones overhead, or warning shots—rather than a sustained attempt to close Hormuz. This will keep shipowners and insurers on edge while allowing Tehran to apply coercive pressure without triggering an immediate large-scale US strike campaign. The second-order effect is a creeping normalization of higher-risk operating conditions, incentivizing only the most risk-tolerant or state-backed fleets to continue normal routing.
