The internal modeled approach is not included in the Basel III reforms announced in 2017 for calculating Credit Value Adjustment (CVA) risk. The Basel III reforms were designed to strengthen the regulation, supervision, and risk management of banks. As part of these reforms, banks are required to calculate CVA risk using specific methods. However, the internal modeled approach is not one of these methods. The reforms instead emphasize the use of two main methods: the standardized approach (SA-CVA) and the simpler basic approach (BA-CVA). The internal modeled approach was removed from the guidelines, indicating a shift away from internal models towards more standardized and simpler methods for calculating CVA risk. This change was made to increase the comparability and consistency of CVA risk calculations across banks and to reduce the reliance on banks' internal models, which can vary significantly in their design and assumptions.

Choice B is incorrect. The standardized approach is indeed a part of the Basel III reforms for calculating CVA risk. This approach uses a set of predefined risk weights and exposure amounts to calculate the CVA risk, which provides consistency across different banks.

Choice C is incorrect. The simpler basic approach is also included in the Basel III reforms for calculating CVA risk. This method simplifies the calculation process by using a fixed percentage for certain types of exposures, making it easier for smaller banks to comply with the regulations.

Choice D is incorrect. All of the above cannot be correct as both The Standardized Approach and The Simpler Basic Approach are included in Basel III reforms for calculating Credit Value Adjustment (CVA) Risk.

Things to Remember

• Basel III reforms aim to strengthen the regulation, supervision, and risk management of banks.
• Credit Value Adjustment (CVA) risk is the risk of loss due to changes in the credit risk of counterparties.
• The Standardized Approach (SA-CVA) and the Simpler Basic Approach (BA-CVA) are the main methods recommended for calculating CVA risk under Basel III reforms.
• Internal modeled approach, while not included in Basel III reforms for CVA risk calculation, was previously used by banks to calculate CVA risk based on their internal models.
