The US industry’s total direct written cyber premiums grew 8% in 2018 to $2 billion, down from 37% growth in 2017. The country is by far the largest market in the world for cyber coverage.


The cyber insurance market remains a source of growth for U.S. property/casualty insurers; however, that growth is slowing, according to Fitch Ratings.


But Fitch expects the market will continue to grow.


After several years of brisk growth, U.S. cyber insurance segment revenue moderated in 2018,” said Gerry Glombicki, director of Insurance at Fitch Ratings.


“However, we continue to believe that high profile cyber events, desire for more sophisticated risk management and improved pricing will buoy the segment in the long term.”


“Fitch has concerns that favorable results could promote price competition, looser underwriting terms and conditions, and attract naive capacity, all which could cause significant disruptions to this immature and untested market,” Glombicki added.


Market concentration in U.S. cyber insurance remains relatively concentrated with the top 10 writers holding 71 per cent market share in 2018. Changes in market share rankings were limited year-over-year. Chubb Limited continues as market leader for stand-alone and package cyber premiums combined.


Effects in Europe and other jurisdictions of regulatory and legal requirements, such as the EU’s Global Data Protection Regulation (GDPR), to manage and protect private and sensitive data or endure significant fines and penalties, are also spurring more interest in cyber risk management and coverage, Fitch said.


According to Fitch, reports from insurance brokers and other experts show gradual increases in take-up rates for cyber coverage, and potential for further market expansion.


Standalone cyber insurance premiums grew 12% in 2018, according to insurer statutory financial data. Fitch said high profile cyber events and previous uncertainty around cyber terms in commercial insurance policies continue to demonstrate the need for coverage. Insurers are addressing silent cyber risks by adding affirmative coverage in policies, including sublimits and cyber endorsements, but these efforts vary widely among individual companies.


To date, the cyber market has shown strong profitability. Statutory industry direct loss ratios for standalone policies remained consistently favorable at 34% in 2018 from 35% in 2017, but Fitch cautioned that this does not necessarily confirm similar results going forward.


Fitch analysts said limited historical claims data present challenges for new underwriters and insurers that ultimately do underwrite cyber policies face tremendous uncertainty in measuring the likelihood and ultimate cost of potential cyber events, which can range from attacks to energy infrastructure to ransomware or cloud attacks.
