AI Summary of Article 325bp Particular requirements for an internal default risk model

The internal default risk model, as outlined in Article 325bm, is designed to effectively model both the individual and simultaneous defaults of issuers. Key requirements include reflecting economic cycles and capturing correlations between recovery rates and systematic risk factors. Moreover, institutions must adhere to stringent criteria for simulating default probabilities and loss given default (LGD), ensuring accurate and objective data underpins their estimates.

Institutions are mandated to document their models transparently, aligning with their internal risk management practices and submission requirements to the EBA for regulatory technical standards. Independent model validation through stress tests and sensitivity analyses is also essential to ensure comprehensive risk assessment.

Article 325bp Particular requirements for an internal default risk model

1. The internal default risk model referred to in Article 325bm(1) shall be capable of modelling the default of individual issuers as well as the simultaneous default of multiple issuers, and shall take into account the impact of those defaults in the market values of the positions that are included in the scope of that model. For that purpose, the default of each individual issuer shall be modelled using two types of systematic risk factors.

2. The internal default risk model shall reflect the economic cycle, including the dependency between recovery rates and the systematic risk factors referred to in paragraph 1.

3. The internal default risk model shall reflect the nonlinear impact of options and other positions with material nonlinear behaviour with respect to price changes. Institutions shall also have due regard to the amount of model risk inherent in the valuation and estimation of price risks associated with those products.

4. The internal default risk model shall be based on data that are objective and up-to-date.

5. To simulate the default of issuers in the internal default risk model, the institution's estimates of default probabilities shall meet the following requirements:
