The outage will lead to reviews of underwriting criteria as concerns are raised about single points of failure, according to Moody’s Ratings.
Published July 30, 2024The July 19 outage is widely considered one of the largest IT disruptions in history, after about 8.5 million Microsoft devices were knocked offline.
The outage led to the cancellation of thousands of commercial airline flights, hospitals postponing surgeries, the temporary disruption of 911 emergency services in multiple states and financial transactions being disrupted .
“Reinsurers regularly review claims following an event that impacts multiple insureds,” Laline Carvalho-Neff, vice president, senior analyst at Moody’s Ratings, said via email. “We expect reinsurers to reevaluate underwriting practices, especially for systems failure coverage, to ensure there’s clear understanding of the risk and pricing of the exposure.”
A study released last week from Parametrix showed the outage would lead to $5.4 billion in direct losses for the Fortune 500, excluding the impact on Microsoft. Insurance was likely to cover between 10% and 20% of those losses.
A separate study by CyberCube predicted the cyber insurance market could face preliminary insured losses of up to $1.5 billion.
The outage was exactly the type of event the industry has been worried about for years, serving as an example of aggregation risk, according to analysts.
“The interconnectedness of systems was on full display last week and demonstrated how businesses can be brought to a standstill abruptly and on a large scale,” Sridhar Manyem, senior director, industry research and analytics at AM Best , said via email.
Delta Air Lines is under investigation from the Department of Transportation for its handling of the outage, which led to thousands of flights being canceled and passengers stranded for days.
