A global pandemic is the most important extreme risk for the insurance industry to worry about in the long term, according to a survey of global insurance industry executives conducted by Towers Watson.

Rounding out the top three extreme risks of concern are a large-scale natural catastrophe and a food/water/energy crisis, the survey found.

Other top 10 extreme risks named in the Towers Watson survey include cyber-warfare, an economic depression, a banking crisis and a default by a major sovereign borrower.

Votes were compiled in a wiki survey which enabled participants to add their own ideas. Over 30,000 votes were cast.

Meanwhile, a new report by AonBenfield says pandemic risk remains the most important mortality exposure for the insurance industry and is placed above other forms of catastrophic event including natural catastrophes, nuclear explosions, and terrorism.

In Pandemic Perspective, AonBenfield points out that according to historical data, pandemics are large enough to destabilize the insurance market more than once every 200 years, with three global pandemics recorded in each of the last three centuries.

This suggests that the majority of people working in the insurance industry today are likely to face at least one pandemic during their careers. Insurers should be aware that now is the time to anticipate and educate themselves on pandemic risk, and begin to model it.”
