Role of reinsurance, retrocession, and pricing in net losses
The report details how risk transfer and catastrophe pricing shape net exposure. The 50 insurers with the largest natural catastrophe exposure face a combined gross exposure of about $430 billion under the 1-in-250-year event. After reinsurance and retrocession, mean exposure falls from about 34% of capital to about 15%, or roughly $225 billion on a net basis. Catastrophe premium loadings further reduce residual exposure, bringing mean net exposure to around 8% of capital. In the modeled 1-in-250-year scenario, S&P estimated that capital would decline by about 8% on average, a level that, in many cases, could be covered by one year’s earnings. Across insurer types, reinsurance utilization is broadly consistent at about 50%, according to the agency. Larger insurance groups in the sample show lower risk concentration and relatively less dependence on reinsurance: in S&P’s scenario, net exposure to capital for the cohort falls to about 20%, supported by average reinsurance cover of around 50%.
