Shipping insurance costs for vessels transiting the Strait of Hormuz have surged up to four times, with 'war risk' premiums now exceeding 1% of a vessel's value. This increase forces shipowners to seek specialized coverage and impacts global trade, as some operators consider alternative routes.

'War Risk' Premiums in Strait of Hormuz Soar Four Times

The Strait of Hormuz is currently classified as an extreme war risk zone for insurance purposes, leading to a dramatic increase in premiums. These premiums now exceed 1% of a vessel's value, representing about four times the total insurance cost prior to the start of the Iran war. This surge is driven by insurance underwriters requiring specialized coverage for ships transiting the strait due to heightened geopolitical tensions.

Soaring Costs Lead to Route Diversions and Reduced Traffic

Insurance rates for transiting the Strait of Hormuz have reportedly reached 1% to 5% of a ship's total hull value. For a typical $100 million tanker, this translates to roughly $1 million to $5 million per transit, a significant increase from pre-conflict rates of only 0.15% to 0.25%. These premiums experience daily volatility, varying by vessel age, type, and specific risk factors. Reports also indicate that Iran is charging approximately $2 million per ship as a 'safe corridor' fee, in addition to standard insurance. Consequently, many operators are choosing to avoid the region or take longer, alternative routes, leading to a drop in vessel traffic through the strait.
