In July 2015, the Basel Committee of Banking Supervision (BCBS) published a consultative paper on credit valuation adjustment (CVA) risk to improve the current regulatory framework. In February 2016, first improvements of this framework have been introduced within the QIS instructions for the QIS based on December 2015 results. The consultative document presents a revision of the current framework addressing three major issues:
• ensure that all important drivers of CVA risk and CVA hedges are covered in the Basel regulatory capital standard
• align the capital standard with the fair value measurement of CVA employed under various accounting regimes
• ensure consistency with the proposed revisions to the market risk framework under the Basel Committee's FRTB
This paper highlights the key differences of current and future calculation approaches for regulatory CVA risk capital charges, including the eligibility criteria for using the different approaches. The BCBS consultative paper proposes two frameworks to accommodate different types of banks with respect to the ability to calculate CVA sensitivities:
• The “FRTB-CVA framework” consisting of the standardized approach (SA-CVA) based on CVA sensitivities
• The “Basic CVA framework“ (BA-CVA), based on a formula similar to the current standardized method
In section two we outline different sample portfolios and a market data environment to calculate exemplary results for the different approaches. In section three, the calculation results are presented and the most relevant input factors are described. The conclusion includes results and recommended future action items for both banks and regulators.
