War-Risk Insurance and Freight Rates for Gulf Tankers Surge, Diverting Flows to Alternative Routes

Moderate confidence (79%)
Risk direction: volatile · Impact: HIGH
Executive summary
Over the next seven days, war-risk premiums and freight rates for tankers operating in and near the Persian Gulf are likely to climb sharply, prompting some shipowners to avoid or surcharge voyages to Iranian and potentially broader Gulf ports. Charterers will consider rerouting or drawing down inventories, while some spot cargoes are delayed or cancelled. This will effectively tighten physical supply even before any formal closure of Hormuz, rewarding operators willing to accept higher risk and marginalizing poorly capitalized shipping firms. Confirmation would be broker reports of sharply higher Gulf war-risk rates and ballasting avoidance of high-risk zones; denial would be stable premiums despite repeated strikes and missile incidents.
