Iran-Linked Shipping and Insurance Costs Rise Further After Tanker Disabling Attack

Full prediction
In the next 24 hours, war-risk premiums and insurance rates for vessels loading in or transiting near Iranian waters and the Strait of Hormuz will increase further following the disabling attack on a tanker off Oman. Charterers will either demand higher rates for voyages linked to Iranian crude or seek alternative load ports where possible, reallocating spot tonnage and pushing up Suezmax and VLCC rates. This will incrementally raise delivered crude costs into Asia and Europe and feed into broader commodity risk sentiment. Confirmation would be broker reports of higher war-risk add-ons, wider freight spreads on Hormuz-exposed routes, and anecdotal voyage diversions; denial would be insurers and shipowners publicly downplaying risk and keeping premia unchanged.
