Open Source in Finance Forum London 2026

Financial institutions are using the FINOS 'physrisk' project to bring calculations of physical climate risk in-house. Although excellent vendor solutions exist for managing physical risks, many Banks are concerned by the 'black box' issue: is it really possible to manage model risk without being truly hands-on? Moreover, it is an attractive option to base a system on public domain data, layering on top only the commercial data that brings real value. The goal is not to be paying for public-domain data.
We give a demonstration of how financial institutions can internalise the systems, and how public domain data can be mixed with commercial for capabilities on a par with the best vendor solutions – but fully in the hands of the modelling teams.
