Hello, thank you for taking the time to post your question!
The main changes introduced by this framework are that there is a tighter trading and banking book boundary, meaning that banks are prevented from reclassifying assets between the two books to minimize capital requirements. The framework also introduced stricter capital calculations for both the internal and standardized approaches for calculating capital.
I hope that helps get you moving in the right direction! Feel free to reach out if you have any additional questions beyond that :)
