European insurers are emerging as defensive plays within financial stocks as the U.S.-Iran conflict intensifies, according to Barclays analysts. The brokerage notes that European insurers have strong balance sheets and limited underwriting exposure to regional hostilities, making them relatively insulated from escalating geopolitical risks.

Barclays highlights that war-related risks are concentrated in specific business lines including political risk, marine, energy, aviation, cyber, and international property. These exposures represent a small portion of European composite insurers' portfolios, with most concentrated among London Market insurers and reinsurers. War risk exposure is particularly complex due to its small premium base of less than U.S. $3 billion annually across marine and aviation.

The brokerage identifies Hiscox, Lancashire, and Conduit as potentially most exposed, with marine, aviation, and political risk premiums accounting for 5-15% of total premiums. Major reinsurers including Swiss Re, Munich Re, Hannover Re, and SCOR also face heightened exposure. Meanwhile, retail property and casualty insurers like Admiral, Sabre, Tryg, and Alm. Brand have no underwriting exposure to the conflict.
