Bloomberg Markets reports that London marine insurers are receiving fewer inquiries for voyages transiting the Strait of Hormuz, while some say the cost of cover has increased. The shift suggests shipowners are becoming more cautious as tensions between the US and Iran intensify.

For tanker markets, any pullback in transit appetite through Hormuz matters immediately. The strait is a critical chokepoint for crude and product flows from the Gulf, and changes in insurance pricing, routing decisions, or vessel availability can quickly affect tanker movements, freight sentiment, and regional export logistics visible in TankerMap flow monitoring.
