Managing and Modeling Emerging Risks

Posted at 1:00 AM ET

Here we review GC Capital Ideas posts on the challenges (re)insurers face managing and modeling casualty catastrophe risks.

The Rise of Emerging Risk and Casualty Catastrophe Models: The modeling of emerging and casualty catastrophe risks remains challenging and the models continue to vary in their approach, level of development and industry acceptance. With the potential scenarios numerous, diverse and constantly changing, there is no single model or approach that could contemplate all of them. Furthermore, the various disaster scenarios with which carriers are being increasingly confronted needs to be prioritized and synthesized within their enterprise risk management framework. By their very definition, there may be limited data on hand on which to base any modeling. As a result, much of the industry continues to rely on multiple models and actuarial approaches that encompass model applications, probable maximum loss (PML) estimates, realistic disaster scenarios, experience and exposure ratings to create a broad set of scenarios and deterministic views.

Integrating & Synthesizing New Emerging Risks - Within the ERM Framework: One purpose of enterprise risk management (ERM) is to help (re)insurers determine how much capital is needed to support the risks they assume (subject to risk tolerance). Instead of segmenting portfolios and handling each peril on a standalone basis, a robust ERM methodology would use a holistic approach to risk and capital management where threats are identified and monitored, all action plans are developed and risks are measured.
