Closing the Protection Gap

Aggregate Reinsurance for Sever Convective Storms

Retained thunderstorm risk is the biggest problem facing US insurers

The Problem:

Reinsurers no longer offer affordable and scalable reinsurance
capacity
for earnings perils like severe convective storms that erode
a primary carrier's surplus and earnings

  • Traditional CAT exhibit high basis risk and low skill when predicting aggregate losses caused by high-frequency, low-severity perils like hail, wind, and tornado
  • Socioeconomic factors produce large loss cost uncertainty for reinsurers (exposure management, claims handling, inflation)
  • The supply of reinsurance capacity has decreased significantly for frequency protection against aggregate SCS losses

The financial impact on primary carriers:

Earnings volatility and the frequency of credit rating downgrades
have increased significantly in recent years

What is the Demex SCS Re Model?

A predictive model for retained Severe Convective Storm (SCS) losses across an insurer's portfolio, which forms the basis of a parametric aggregate reinsurance agreement.
Our modeling approach has been meticulously constructed to produce the most accurate predictions possible.

Premium cost is partially offset by capital efficiency gains.

The CFO conversation has changed

With capital credit recognition, Demex protection is capital-efficient risk transfer that your rating agency accepts. The premium is not just expense - it's a recognized reduction in net risk.
