Increased Humanitarian Access Constraints and Insurance Costs in the Strait of Hormuz

Moderate confidence (60%)
Risk direction: volatile · Impact: MEDIUM
Executive summary
In the next 24 hours, humanitarian shipments and commercial logistics transiting the Strait of Hormuz will face tighter access constraints, heightened inspections, and increased insurance premia due to Iran’s reported ship seizures and unclear MoU status. Vessel operators will become more risk-averse, potentially delaying or rerouting cargoes, including essential goods bound for conflict-affected states in the broader region. While basic flows will continue, the perception of arbitrary interdiction risk will discourage smaller operators and raise costs for aid consignments. A sudden, credible announcement of a 60-day free-navigation guarantee could partially reverse this but is unlikely to fully dispel caution immediately.
