War-risk insurance costs for voyages through the Strait of Hormuz have moved higher, while London marine insurers are reportedly seeing fewer inquiries for transits, according to gCaptain. The shift suggests some shipowners are becoming more selective about Gulf voyages as tensions between the US and Iran escalate.
For tanker markets, any pullback in Hormuz routing matters immediately. The strait is a critical outlet for crude and LNG exports from the Gulf, so higher insurance costs and greater owner caution can tighten vessel availability, lift freight exposure and add uncertainty to regional oil and gas shipping flows tracked by TankerMap.
