An Oxford University study in Nature Communications estimates that disruptions at 24 major maritime chokepoints affect about $192 billion of seaborne trade each year. The losses from delays, rerouting, insurance and freight add up to roughly $14 billion annually.
The findings highlight the recurring cost of chokepoint risk, which can keep freight and insurance premiums elevated for bulk and container shipments. The study reports no new event, so its direct effect on grain or feed prices is limited.
