AI Summary of Article 325az Alternative internal model approach and permission to use alternative internal models

The alternative internal model approach enables institutions to calculate their own funds requirements for market risk, provided they satisfy the outlined criteria. Competent authorities will grant permission based on compliance with specific articles regarding trading desk establishment, justification for inclusion, back-testing, P&L attribution, and restrictions on securitisation positions.

Institutions must promptly inform authorities if any trading desk fails to meet these requirements, necessitating a switch to the standardised approach for market risk calculations. Additionally, significant changes to the use of alternative models require prior authorisation, ensuring transparency and regulatory oversight throughout the process.
