AI Summary of Article 325ba Own funds requirements when using alternative internal models

The regulatory framework requires institutions employing an alternative internal model to establish own funds requirements for trading desk portfolios. These requirements, defined as the higher of specific calculated values, encompass both expected shortfall and stress scenario risk measures from the previous day or averaged over the preceding sixty business days, subject to specific adjustments for the institution's own debt instruments.

Furthermore, institutions must account for additional own funds relating to default risk for traded debt and equity instruments, while excluding their own debt instruments from this requirement. The calculation approach extends to both trading and non-trading book positions generating relevant risk, ensuring comprehensive market risk assessment.
