Stress test model
Cassandra is the top-down stress test framework that DNB regularly uses to assess financial system vulnerabilities in the light of tail-risk events. Cassandra is modular in its set up and can be tailored to high-level as well as granular stress test analyses.
Within Cassandra, various model approaches are available to study how factors such as credit risk, market risk and PnL dynamics can have a final impact on the capital position of financial institutions in stress scenarios. In recent years, Cassandra has been used in various ways, such as providing analyses in the Overzicht Financiële Stabiliteit (Financial Stability Report), calculations in the context of the EBA stress test, or questions related to the financial stability implications of climate change.
