(5)For the purposes of the assessment under Article 23(1), point (e), of Regulation (EU) 2019/2033, the competent authority should be required to assess whether the K-CMG approach is appropriate insofar it reflects the risk profile of the investment firm’s trading book positions. An investment firm should be required to compare regularly its own risk assessment with the margins required by clearing members, for the purpose of assessing whether those margins are still a good indicator of the level of risk to market of the investment firm. At the point of assessment by the competent authority, the investment firm should make a comparison between the capital requirements under K-NPR and K-CMG and should be able to adequately justify the difference between those capital requirements to the competent authority. An assessment by the competent authority should be positive only when all these conditions are met. In particular, the competent authority should ensure that the investment firm is able to monitor and adequately justify difference between the outcome of the two methodologies, K-NPR and K-CMG, especially in cases of large variations of the required margins.
