Elevated shipping insurance premiums and rerouting increase global freight costs

Executive summary
Over the next 7 days, war-risk insurance premiums for vessels transiting the Gulf and Indian Ocean approaches are likely to rise significantly, and some operators will reroute or delay voyages, increasing overall freight costs on energy and some container routes. Insurers will respond to clustered IRGC attacks, high-profile US warnings, and the risk of miscalculation in crowded sea lanes by repricing coverage. These added costs will gradually feed through into delivered prices of fuels and potentially consumer goods, particularly in Europe and Asia. A minority of state-owned or heavily subsidized fleets may continue transits with government backstops.
