Dive Insight:

London-based Lloyd's operates a major insurance and reinsurance marketplace with more than 200 lines of business. Last year, Lloyd's was ranked AM Best's seventh-largest reinsurer of 2021.

Lloyd's, which boasts significant insurance market influence, recently caused waves in its long-anticipated decision to phase out coverage for state-sponsored cyberattacks, which Lloyd's announced in August. 

The new guidance, while not a mandate, calls on managing agents to apply due diligence when approaching the complexities of state-sponsored attacks. The German-based reinsurer Munich Re too is rethinking cyber policies to exclude war. 

The insurance industry is changing cyber guidance because there's an inherent imbalance, where the number of cyber insurance policy claims threatens to upend the market's ability to effectively operate.
