Treatment of CIUs in internal model for market risk – own funds requirement (add-on)

Has the add-on for specific risk for CIUs according to Art. 364 (2) lit. a) in any case to be calculated for CIUs which are included in an internal model for market risk using a different approach than those described in Art. 350 (1) or 350 (2) (e.g. based on the liquid price of the CIU)?

There might be different approaches to include CIUs in an internal market risk model – one possibility to model CIUs is to take the liquid price of the CIU. This possibility is explicitly mentioned in the new FRTB (and the CRR2-draft respectively). Due to the fact that no look-through is conducted, but only the liquid prices would be used for modelling purposes, Art. 350 (1) and (2) CRR would not be met. Please mind that we assume that the condition in Art. 364 (2) lit. a) (in conjunction with Art. 350 (1) and (2) CRR) is about how the bank actually models the CIU positions, not about whether the CIU in question in general matches the description in Art. 350 (1) or (2), respectively . Following the paragraph above, institutions which do have the permission to model specific risk have to calculate an additional own funds requirement for specific risk according to Art. 364 (2) lit. a) CRR for CIUs which are modelled using liquid prices – where applicable – in accordance with Chapter 2, Section 6. Additionally, in this case it should be noted that a similar treatment of a look-through approach according to Art. 350 (1) and (2) CRR and modelling CIUs using a liquid price would not be appropriate from a prudential point of view for the followingIf the look-through approach according to Art 350 (1) or (2) CRR is applied, the underlyings of the CIU are the basis for calculating own funds requirements, which means that for a corporate bond CIU the underlyings have to be included into the calculation of the IRC. If the CIU is modelled using its liquid price, no own funds requirements for specific risk (VaR/SVaR) and IRC would be calculated (if it is verified that specific risk of the CIU does not exist). This different treatment would not be appropriate, because the institution performing the look-through approach would have more effort (daily look through) and presumably higher own funds requirements. Art. 364 (2) lit. a CRR is mentioning an add-on calculated following the standardized approach.
