COMMISSION DELEGATED REGULATION (EU) 2022/2059

of 14 June 2022

supplementing Regulation (EU) No 575/2013 of the European Parliament and of the Council with regard to regulatory technical standards specifying the technical details of back-testing and profit and loss attribution requirements under Articles 325bf and 325bg of Regulation (EU) No 575/2013

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EU) No 575/2013 of 26 June 2013 of the European Parliament and of the Council on prudential requirements for credit institutions and amending Regulation (EU) No 648/2012 (1), and in particular Article 325bf(9), third subparagraph, and Article 325bg(4), third subparagraph, thereof,

Whereas:

(1) Article 325bf(2) of Regulation (EU) No 575/2013 requires institutions to count daily overshootings on the basis of back-testing of the hypothetical and actual changes in their portfolio’s value composed of all the positions assigned to their trading desks. Such back-testing is intended to assess, depending on the level at which it is performed, whether it is appropriate to calculate the own funds requirements for positions in a trading desk using the alternative internal model approach, and whether the own funds requirements associated with modellable risk factors are adequate. Article 325bf(4) of Regulation (EU) No 575/2013 requires institutions to use the end-of-day value of the portfolio as a starting point for such back-testing, including all adjustments, such as reserves or any valuation adjustment.

(2) In the back-testing of the value-at-risk number, some market risk effects that are not captured by the internal risk-measurement model should still be included in the actual changes in the portfolio’s value. Accordingly, all adjustments related to market risk, regardless of the frequency at which they are updated by institutions, should be included in the actual changes in the portfolio’s value. The back-testing of the value-at-risk number with the hypothetical changes in the portfolio’s value, however, should be performed under the assumption of a static portfolio. Therefore, institutions should include in the computation of such hypothetical changes in the portfolio’s value only those adjustments that are calculated daily and that are included in the internal risk-measurement model.

(3) In some cases, it is possible that, due to the nature of an adjustment and due to the internal risk management applicable to that adjustment, such adjustment is computed across sets of positions that are assigned to more than one trading desks. To ensure harmonisation across the Union, institutions should be required, when calculating the actual and hypothetical changes in a trading desk’s portfolio value, to either recalculate such adjustment for each trading desk on the stand-alone basis of the positions assigned to the trading desk only, or, where specific conditions are met, to reflect the changes arising from such adjustment only in the context of the back-testing referred to in Article 325bf(6) of Regulation (EU) No 575/2013. Accordingly, where institutions perform the end-of-day valuation process to derive the trading desks’ end-of-day portfolio values, they should not be allowed, when calculating hypothetical and actual changes at the trading desk level, to allocate the adjustment to the trading desks in a manner that is proportionate to each trading desks’ contribution to the value of the adjustment.

(4) The profit and loss attribution requirement laid down in Article 325bg of Regulation (EU) No 575/2013 has a prominent role in ensuring that the theoretical changes and the hypothetical changes in the trading desk portfolio’s value are sufficiently close. The statistical tests included in the international standards developed by the Basel Committee for Banking and Supervision, the Spearman correlation coefficient and the Kolmogorov-Smirnov test metric, to operationalise the profit and loss attribution requirement are appropriate for that purpose and should therefore be used by institutions.

(5) In the international standards, it is laid down that institutions should satisfy an additional capital requirement where the theoretical and hypothetical changes in the value of trading desks’ portfolios are not sufficiently close. In that situation, institutions should be required to calculate and report to competent authorities that additional capital requirement for those trading desks.

(6) When reporting the profit and loss attribution results in accordance with Article 325az(2), point (d), of Regulation (EU) No 575/2013, institutions should also highlight where the hypothetical changes and theoretical changes to the value of a trading desk’s portfolio materially differ. This should help institutions to identify potential deficiencies in the calculation of the theoretical changes.

(7) When assessing compliance with the profit and loss attribution requirement, theoretical changes in a portfolio’s value are compared against hypothetical changes which are calculated under the assumption of a static portfolio. That comparison aims at identifying the materiality of differences in the valuation processes of the institution’s risk-measurement model producing the theoretical changes, and the valuation processes of the institution’s internal systems producing the hypothetical changes. To ensure that that comparison is not affected by changes in the composition of the portfolio, the theoretical changes to a portfolio’s value used in the profit and loss attribution requirement should also be calculated under the assumption of a static portfolio.

(8) To ensure consistency with international standards, the hypothetical changes in the portfolio’s value that are calculated for the purpose of assessing compliance with the profit and loss attribution requirement should be aligned with the hypothetical changes in the portfolio’s value, that an institution calculates for the purposes of the back-testing.

(9) Differences between the valuation processes producing hypothetical and theoretical changes in a portfolio’s value may be due to omissions of certain risk factors in the risk-measurement model or simplifications of the risk-measurement model. Other differences may be due to misalignments in the data that an institution uses as inputs for determining its portfolios’ value. To avoid additional sources of discrepancies resulting from such differences in input data, institutions should be allowed to align the input data provided that some specific conditions are met.

(10) The frequency at which the results of the profit and loss attribution requirement are to be reported should be aligned to the frequency at which the modellability of the risk factors is assessed and the frequency at which the own funds requirements for market risk are reported. That way, institutions will be able to determine the own funds requirements for market risk based on consistent results for the back-testing requirements, the profit and loss attribution requirements and the assessment of modellability.

(11) The manner in which institutions should aggregate their total own funds requirements for market risk should be aligned with the international standards. Therefore, the aggregation formula should reflect the results of the profit and loss attribution requirement, including the additional capital requirement where theoretical and hypothetical changes are not sufficiently close. In addition, the aggregation formula should reflect a reduction in diversification benefits where the own funds requirements for a trading desk are calculated with the alternative standardised approach and not with the alternative internal model approach.

(12) In order to assist competent authorities to check compliance of institutions with this Regulation, institutions should be required to document their implementation of this Regulation.

(13) The provisions of this Regulation are closely linked to each other, since they all deal with elements to be included in changes of a trading desk portfolio’s value for the purposes of calculating the own funds requirements for market risks using the alternative internal model approach. To ensure coherence between those provisions, which should enter into force at the same time, to facilitate a comprehensive understanding of those provisions and to ensure easy access to them by persons subject to the obligations set out within, it is desirable to include all the regulatory technical standards required by Article 325bf(9), third subparagraph, and Article 325bg(4), third subparagraph, of Regulation (EU) No 575/2013 in a single Regulation.

(14) This Regulation is based on the draft regulatory technical standards submitted to the Commission by the EBA.

(15) The EBA has conducted open public consultations on the draft regulatory technical standards on which this Regulation is based, analysed the potential related costs and benefits, and requested the advice of the Banking Stakeholder Group established in accordance with Article 37 of Regulation (EU) No 1093/2010 of the European Parliament and of the Council (2),

HAS ADOPTED THIS REGULATION:

CHAPTER 2

TECHNICAL SPECIFICATION OF THE PROFIT AND LOSS ATTRIBUTION REQUIREMENT

Section 1

Criteria necessary to ensure that the theoretical changes and the hypothetical changes in the value of a trading desk portfolio are sufficiently close and consequences for trading desks that do not meet that condition

Article 6 General requirements 1. For the purposes of Article 325bg(2) of Regulation (EU) No 575/2013, institutions shall calculate, for a given trading desk’s portfolio, the Spearman correlation coefficient laid down in Article 7 of this Regulation, and the Kolmogorov-Smirnov test metric laid down in Article 8 of this Regulation and, based on the results of those calculations, apply the criteria referred to in Article 9 of this Regulation. Where, according to those criteria, the theoretical changes and the hypothetical changes in the value of a trading desk portfolio are not sufficiently close, institutions shall be subject to the consequence set out in Article 10 of this Regulation. 2. For the purposes of paragraph 1, institutions may align the point in time (snapshot time) for which they calculate the theoretical changes in the trading desk portfolio’s value with the snapshot time for which they calculate the hypothetical changes in that value.

Article 7 Calculation of the Spearman correlation coefficient 1. Institutions shall calculate the Spearman correlation coefficient referred to in Article 6(1) of this Regulation by performing the following steps in the following order: (a) they shall determine the time series of observations of the hypothetical and theoretical changes in the trading desk portfolio’s value for the most recent 250 business days; (b) from the time series of the hypothetical and theoretical changes referred to in point (a), institutions shall produce the corresponding time series of ranks in accordance with paragraph 2, treating the time series of the hypothetical and theoretical changes as the originating time series; (c) they shall calculate the Spearman correlation coefficient in accordance with the following formula: Where: R HPL = the time series of ranks produced from the time series of hypothetical changes referred to in point (b); R RTPL = the time series of ranks produced from the time series of theoretical changes referred to in point (b); = the standard deviation of the time series of ranks RHPL calculated in accordance with paragraph 3, point (a); = the standard deviation of the time series of ranks RRTPL calculated in accordance with paragraph 3, point (b); cov (RHPL , RRTPL ) = the covariance calculated in accordance with paragraph 3, point (c), between the times series of ranks RHPL and RRTPL . 2. Institutions shall produce the time series of ranks referred to in paragraph 1, point (b), from an originating time series by performing the following steps in the following order: (a) for each observation within the originating time series, institutions shall count the number of observations with a lower value than that observation within that time series; (b) institutions shall label each observation with the number resulting from the calculation set out in point (a) increased by one; (c) where, as a result of the labelling in accordance with point (b), two or more observations are labelled with the same number, institutions shall in addition increase the numbers of those labels with the following fraction: where N equals the quantity of the labels with the same number; (d) institutions shall consider as time series of ranks, the time series of the labels obtained in accordance with points (b) and (c). 3. Institutions shall calculate the standard deviation of the time series of ranks RHPL in accordance with the formula laid down in point (a), the standard deviation of the time series of ranks RRTPL in accordance with the formula laid down in point (b), and the covariance between those time series in accordance with the formula laid down in point (c) as follows: (a) ; (b) ; (c) ; Where: i = the index that denotes the observation in the time series of ranks; = the ‘i-th’ observation of the time series of ranks R HPL ; = the mean of the time series of ranks RHPL ; = the ‘i-th’ observation of the time series of ranks RRTPL ; = the mean of the time series of ranks RRTPL .

Article 8 Calculation of the Kolmogorov-Smirnov test metric 1. Institutions shall calculate the Kolmogorov-Smirnov test metric referred to in Article 6(1) of this Regulation by performing the following steps in the following order: (a) they shall determine the time series of the most recent 250 business days of observations of the hypothetical and theoretical changes in the trading desk portfolio’s value; (b) they shall calculate the empirical cumulative distribution function of the hypothetical changes in the trading desk portfolio’s value from the time series of the hypothetical changes referred to in point (a); (c) they shall calculate the empirical cumulative distribution function of the theoretical changes in the trading desk portfolio’s value from the time series of the theoretical changes referred to in point (a); (d) they shall obtain the Kolmogorov-Smirnov test metric by calculating the maximum difference between the two empirical cumulative distributions calculated in accordance with points (b) and (c) at any possible value of profit and loss. 2. For the purposes of paragraph 1, the empirical distribution function obtained from a time series shall be understood as the function that, given any number as input, results in the ratio of the number of observations within the time series with lower or equal value than the input number to the total number of observations within the time series.

Article 9 Specification of criteria necessary to ensure that the theoretical changes and the hypothetical changes in the value of a trading desk portfolio are sufficiently close 1. For the purposes of Article 325bg(2) of Regulation (EU) No 575/2013, institutions shall classify each of the trading desks as a green, orange, yellow or red zone desk in accordance with paragraphs 2 to 5. Where a trading desk is classified as a green zone desk, theoretical changes and the hypothetical changes in the value of that trading desk’s portfolio shall be considered sufficiently close. Where a trading desk is classified as an orange, yellow or red zone desk, theoretical changes and the hypothetical changes in the value of that trading desk’s portfolio shall not be considered sufficiently close. 2. A trading desk shall be classified as a ‘green zone desk’ where all of the following conditions are met: (a) the Spearman correlation coefficient for the trading desk, calculated in accordance with Article 7 of this Regulation, is greater than 0,8; (b) the Kolmogorov-Smirnov test metric for the trading desk, calculated in accordance with Article 8 of this Regulation, is lower than 0,09. 3. A trading desk shall be classified as a ‘red zone desk’ where either of the following conditions is met: (a) the Spearman correlation coefficient for the trading desk, calculated in accordance with Article 7 of this Regulation, is lower than 0,7; (b) the Kolmogorov-Smirnov test metric for the trading desk, calculated in accordance with Article 8 of this Regulation, is greater than 0,12. 4. A trading desk shall be classified as an ‘orange zone’ desk where all of the following conditions are met: (a) the trading desk is not classified as either a green or a red zone desk; (b) the own funds requirements for all the positions assigned to that trading desk were calculated in the previous quarter based on the alternative standardised approach set out in Part Three, Title IV, Chapter 1a of Regulation (EU) No 575/2013. 5. A trading desk which is not classified as a green, orange or red zone desk, shall be classified as a ‘yellow zone desk’.

Article 10 Consequences for trading desks that are classified as yellow, orange or red zone desks 1. Institutions calculating the own funds requirements in accordance with the alternative internal model approach set out in Part Three, Title IV, Chapter 1b of Regulation (EU) No 575/2013 for positions assigned to trading desks that have been classified as red, orange or yellow zone desks in accordance with Article 9 of this Regulation shall calculate, in relation to those positions, a capital surcharge in accordance with the following formula: Where: k = as specified in paragraph 2; SAima = the own funds requirements for market risks calculated in accordance with the alternative standardised approach set out in Part Three, Title IV, Chapter 1a of Regulation (EU) No 575/2013 for the portfolio of all positions assigned to trading desks for which the institution calculates the own funds requirements for market risks in accordance with the alternative internal model approach set out in Part Three, Title IV, Chapter 1b of Regulation (EU) No 575/2013; IMAima = the own funds requirements for market risks calculated in accordance the alternative internal model approach set out in Part Three, Title IV, Chapter 1b of Regulation (EU) No 575/2013 for the portfolio of all positions assigned to trading desks for which the institution calculates the own funds requirements in accordance with Part Three, Title IV, Chapter 1b of Regulation (EU) No 575/2013. 2. For the purposes of paragraph 1, the coefficient k shall be calculated in accordance with the following formula: Where: SA i = the own funds requirements for market risks calculated in accordance with the alternative standardised approach set out in Part Three, Title IV, Chapter 1a of Regulation (EU) No 575/2013 for all the positions attributed to trading desk ‘I’; = the indices of all trading desks that have been classified as red, orange or yellow zone desks in accordance with Article 9 of this Regulation among those for which the own funds requirements for market risks are calculated in accordance with the alternative internal model approach set out in Part Three, Title IV, Chapter 1b of Regulation (EU) No 575/2013; = the indices of all trading desks for which the own funds requirements for market risks are calculated in accordance with the alternative internal model approach set out in Part Three, Title IV, Chapter 1b of Regulation (EU) No 575/2013. 3. Institutions calculating the own funds requirements for market risks in accordance with the alternative internal model approach set out in Part Three, Title IV, Chapter 1b of Regulation (EU) No 575/2013 for positions assigned to trading desks that have been classified as red or orange zone desks in accordance with Article 9 of this Regulation shall inform the competent authority thereof when reporting the results of the profit and loss attribution requirement in accordance with Article 325az(2), point (d), of Regulation (EU) No 2013/575.

Section 2

Technical elements to be included in the theoretical and hypothetical changes in a trading desk portfolio’s value for the purposes of the profit and loss attribution requirement

Article 12 Technical elements to be included in the theoretical changes in the trading desk portfolio’s value 1. For the purposes of Article 325bg of Regulation (EU) No 575/2013, institutions shall calculate the theoretical changes in a trading desk portfolio value based on a comparison between the portfolio’s end-of-day value and, assuming unchanged positions in the trading desk portfolio, the value of that portfolio at the end of the subsequent day. 2. Institutions shall calculate the theoretical changes in a trading desk portfolio by using the same techniques, including the same pricing methods, model parametrisations and market data as those used in the risk measurement model. 3. Theoretical changes in a trading desk portfolio value shall only include the changes in the value of all risk factors included in the risk-measurement model to which institutions apply the scenarios of future shocks.

Article 13 Technical elements to be included in the hypothetical changes in a trading desk portfolio’s value for the profit and loss attribution requirement For the purposes of Article 325bg of Regulation (EU) No 575/2013, institutions shall calculate hypothetical changes in a trading desk portfolio’s value in accordance with Article 3 of this Regulation.

Article 14 Alignment of data for the profit and loss attribution requirements 1. For the purposes of Article 325bg of Regulation (EU) No 575/2013, institutions may replace the value of input data for a given risk factor used in the calculation of the theoretical changes in the trading desk portfolio’s value with the value of the input data of the same nature for the same risk factor used in the calculation of the hypothetical changes in the trading desk portfolio’s value, provided either of the following conditions is met: (a) differences in the input data are due to the fact that the data are sourced from different data providers; (b) differences in the input data are due to the fact that the input data are extracted from the market data source at different times during the same business day. 2. For the purposes of Article 325bg of Regulation (EU) No 575/2013, institutions may replace the value of a risk factor used in the calculation of the theoretical changes in the trading desk portfolio’s value with the value of the same risk factor used in the calculation of the hypothetical changes in the trading desk portfolio’s value where all of the following conditions are met: (a) the risk factor used in the calculation of the hypothetical changes in the trading desk portfolio’s value does not directly correspond to the input data; (b) the risk factor has been derived from the input data using techniques of the valuation systems used for the hypothetical changes in the trading desk portfolio’s value; (c) none of the techniques of the valuation systems referred to in point (b) have been rebuilt in the valuation systems used in the risk measurement model in order to derive the value of the risk factor which is used in the calculation of the theoretical changes in the trading desk portfolio’s value.
