Signal
The escalating U.S.-Iran conflict has created a perfect storm in the insurance sector, particularly affecting maritime and aviation coverage. The disruption of shipping through the Strait of Hormuz, combined with attacks on vessels and air cargo restrictions, has reduced global cargo capacity by over 20%. London marine insurers are maintaining coverage but with significantly increased war risk premiums, while major brokers Marsh and Aon are negotiating with the U.S. government to establish new insurance frameworks for tanker protection. The ripple effects extend beyond direct maritime risks to business interruption, cyber threats, and travel insurance exclusions. This confluence of events marks a critical inflection point for insurers, forcing rapid adaptation of risk models and coverage terms while potentially creating new opportunities for specialized war risk coverage products.
