Catastrophe risk modelling

Modelling the aggregate financial impact of natural and man-made catastrophes on an insurance portfolio — hurricane, earthquake, wildfire, flood, cyber, terrorism. The output feeds reinsurance purchasing, capital requirements, and underwriting concentration limits.

The three rungs

Legacy

Catastrophe exposure measured by hand with engineering-informed rules of thumb; no stochastic model, no simulation over 10,000 years of synthetic storms.

Modern

Cloud SaaS and classical ML; tools founded roughly 1995 – 2015.

AI-native

Built around deep learning or LLMs from day one; tools founded mostly post-2015.

Risk Management Solutions (RMS), founded 1988 and acquired by Moody's in 2021 for $2B, is the category's defining incumbent alongside Verisk's AIR Worldwide (now Verisk Extreme Event Solutions). The modern generation of cat modelling is dominated by those two houses, with Moody's RMS now branded as part of the Moody's Insurance Solutions platform. AI-native disruption is active at the edges — new hazard models, machine-learning emulators, AI-driven vulnerability curves — but has not yet displaced the incumbents' 30-year catalogue of calibrated models.
