Swiss Re integrates Fathom data into its internal view of flood risk

Since Swiss Re’s acquisition of Fathom in December 2023, joint teams have worked to expand and align key Fathom datasets to support next-generation flood modeling. Current integration work includes building 50,000-year probabilistic flood event sets that use AI-enhanced climate models to capture more extreme outcomes and remove historical biases. The new models will also embed FathomDEM+, Fathom’s advanced global terrain dataset, to improve accuracy across multiple geographies.  

With Fathom’s high-fidelity flood models already active within the Swiss Re Risk Data Solutions product suite, ongoing joint development is advancing the systematic incorporation of Fathom data across Swiss Re’s underwriting and portfolio management activities, unlocking a diverse range of risk assessment tools for both insurance and corporate clients.

Nearly half of the world’s landmass — home to an estimated four billion people — is currently exposed to flood-related hazards, underscoring the growing importance of decision-grade flood risk data.
