FINAL REPORT ON GUIDELINES ON PROPORTIONATE RETAIL DIVERSIFICATION METHODS

Executive Summary
The EBA is mandated under Article 123(1) of Regulation (EU) No 575/2013 (CRR) to issue Guidelines to specify proportionate diversification methods under the Standardised Approach of credit risk, for the purpose of identifying retail exposures, which are considered as being one of a significant number of similar exposures, such that the risks associated with such exposure are substantially reduced as specified in the first subparagraph, point (c), of Article 123 (1) of the CRR. The reason for this requirement is that the capital requirements set out for the retail exposure class require that exposures eligible for the preferential 75% 1 risk weight represent one of a significant number of exposures with similar characteristics, such that the risks associated with such exposure are substantially reduced as a result of diversification. In the Basel III framework, a retail portfolio is deemed to have sufficient granularity if no aggregate exposure to one counterparty exceeds 0.2% of the overall regulatory retail portfolio, unless national supervisors have determined another method to ensure satisfactory diversification. In the EU,
Article 123 of the CRR requires the EBA to specify the method to be used for assessing whether the
retail portfolio is sufficiently diversified.
The EBA has adopted an approach whereby institutions that do not hold a sufficiently granular portfolio under the Basel 0.2% criterion may still qualify that portfolio for the preferential risk weight. Specifically, less diversified portfolios (i.e. with exposures exceeding the 0.2% threshold) can still be considered sufficiently diversified, provided that no more than 10% of the institution’s eligible retail portfolio exceeds this threshold. This approach promotes harmonisation across the EU through objective metrics, while ensuring that the methods remain proportionate to the size of institutions. Except 1) transactor exposures, which are assigned a 45% risk weight and 2) exposures due to loans granted by an institution to pensioners or employees with a permanent contract against the unconditional transfer of part of the borrower’s pension or salary to that institution, which are assigned a 35% risk weight, if meeting the conditions set out in Article 123(4).

2. Background and rationale
These Guidelines address the mandate granted to the EBA under Article 123(1) of the CRR to specify proportionate diversification methods for retail exposures under which an exposure is to be considered as one of a significant number of exposures with similar characteristics, such that the risks associated with such exposure are substantially reduced. Satisfactory diversification is one of the mandatory requirements for retail exposures to be assigned the preferential retail risk weight, as set out under Article 123(1) of the CRR. The Basel III international standards set out a granularity criterion, whereby no aggregated exposure to one counterparty may exceed 0.2% of the overall regulatory retail portfolio, unless national supervisors have determined another method to ensure satisfactory diversification of the regulatory retail portfolio. These Guidelines make use of this discretion. Smaller institutions tend to have more concentrated retail portfolios than larger institutions. The diversification methods proposed in these Guidelines allow institutions whose retail portfolio is not granular enough to still apply the preferential risk weight, subject to meeting a diversification test where all the inputs are readily available for institutions. The use of simple methods that require straightforward inputs from institutions contributes to meeting the proportionality principle as defined in the mandate and in line with recital 46 of the original CRR as of 26 June 2013 2 , while ensuring harmonisation in the EU and supervisory convergence through objective metrics 3 . The proposed diversification test requires an institution to compare the share of retail exposures that exceed the 0.2% granularity threshold at the level of groups of connected clients (GCCs) in the retail portfolio against the predefined threshold. Under this approach, the calculation of the 0.2% threshold is carried out only once, with reference to the eligible retail portfolio 4 , without excluding exposures exceeding the 0.2% threshold. Specifically, the denominator used for the calculation Extract from recital 46 of CRR: ‘The provisions of this Regulation respect the principle of proportionality, having regard in particular to the diversity in size and scale of operations and to the range of activities of institutions. Respect for the principle of proportionality also means that the simplest possible rating procedures, even in the Internal Ratings Based Approach (’IRB Approach’), are recognised for retail exposures.’ The Guidelines accordingly take into account the guidance received from the EBA Advisory Committee on Proportionality, in particular the recommendations for 2024 in the credit risk area so that the guidance it delivers are drafted in a way that is consistent with and uphold the principle of proportionality without damaging the prudential objectives: EBA Work programme 2024 (europa.eu).

CRR (i.e. the securitisation framework). European üllQ Banking UUCI Authority

FINAL REPORT ON GUIDELINES ON PROPORTIONATE RETAIL DIVERSIFICATION METHODS corresponds to the sum of the exposure values of all exposures in the original retail portfolio. The associated threshold for the diversification assessment is set at 10%. The scope of retail exposures under assessment for ensuring diversification are the retail exposures as already characterized under Article 123 paragraphs (1) and (2) of the CRR. Specifically, institutions should:

Identify the full set of exposures that meet the criteria set out in Article 123 (1), points (a),
(b) and (d) of the CRR.
Exclude any exposures as specified in Article 123(2) of the CRR.
The retail diversification test is to be performed:
Excluding defaulted retail exposures.
For each reference date and at the level of application of the prudential requirements as
required by the CRR. Specifically, the assessment is to be carried out at the level for which minimum own funds requirements are calculated. Where minimum own funds requirements are calculated at the level of the individual institution, the exposures included in the assessment are those of the individual institution. In contrast, where minimum own funds requirements are calculated at consolidated level, the exposures included in the assessment are exposures of all entities included in the scope of the prudential consolidation.
At GCCs’ level. It is recalled that institutions are already mandated to identify GCCs in the
retail portfolio through the retail size criterion specified under Article 123(1)(b) of the CRR. Hence, identification of such GCCs does not represent any additional burden for institutions 5 .
It is recalled that CRR Articles 124(1)(a), 125(1), last sub-paragraph and 126(1), last subparagraph specify that certain exposures secured by mortgages on immovable property
should be assigned the risk weight applicable to the unsecured exposures of the counterparty involved. Whenever the exposure to that counterparty qualifies as retail exposure, those exposures are to be assigned the appropriate risk weight based on the specifications of Article 123 of the CRR. Hence exposures secured by immovable property that are to be risk weighted as retail should also be subject to the retail diversification test, as this is required to assign the relevant retail risk weight.

Exposure value of each individual exposures
€10 €20 €40 €200 /
Total exposure value €3 600 €10 000 €400 €10 000 €24 000 The first step is to calculate the 0.2% threshold and the maximum exposure value below which the whole portfolio is considered to be diversified. In this original retail portfolio, any exposure exceeding €48 is above the 0.2% granularity threshold (0.2% * total exposure value = 0.2%*€24 000 = €48). Hence, the exposures in the subset D exceed the threshold of €48. The second step is to calculate the 10% threshold, which defines the maximum aggregate exposure value of exposures exceeding the 0.2% threshold that may be retained in the portfolio for diversification purposes. In this original retail portfolio, this maximum amount is €2 400 (i.e. 10% * €24 000). No exclusions of exposures are necessary in subsets A, B and C of the retail portfolio, as the exposures in these subsets have an exposure value below the 0.2% granularity threshold (hence they will be assigned the preferential retail RW). In addition, up to 10% of the total exposure values of the portfolio can exceed the 0.2% threshold. This means that up to €2 400 in subset D can be considered to be diversified, which corresponds to 12 exposures (€2 400 / €200). The remaining 38 exposures in subset D are excluded from this preferential treatment and must instead be risk weighted in accordance with
Article 123(4) of the CRR. No more calculations are necessary.

Treatment of securitised exposures
The Guidelines specify that, for institutions that originate or invest in securitisations backed by retail exposures, the diversification assessment must be carried out through three distinct calculations, each referring to a separate sub-portfolio:
(i) First, the institution 7 performs the diversification test on the portfolio of eligible retail exposures that are risk weighted under Chapter 2 of the CRR, excluding securitised exposures for which positions are risk weighted under Chapter 5 of the CRR. This assessment applies to the institution’s own retail portfolio and is performed irrespective of whether the institution acts as originator or investor in any securitisation. (ii) Second, where the institution acts as originator, the diversification condition must also be assessed with respect to the underlying securitised exposures. In accordance with
Article 255(6) of the CRR, these underlying exposures are to be treated as if they had not
been securitised. Therefore, the institution carries out a dedicated calculation on a combined sub-portfolio that includes: the retail exposures underlying the securitisation and all other non-securitised eligible retail exposures. This ensures that originators assess diversification on the full set of retail exposures for which they hold complete obligor information. (iii) Third, for institutions, who are investors of securitisations with retail exposures, the diversification assessment should be performed exclusively at the level of the securitised portfolio, based only on the underlying securitised exposures of the securitisation for which positions are risk weighted under Chapter 5 of Part Three, Title II of the CRR. Furthermore, in order to limit operational burden, the Guidelines will automatically consider the diversification condition as fulfilled, if information on the obligor and exposure value is not available in the disclosure templates referred to in Article 7. This derogation should apply only as long as the templates mandated under Article 7(4) of Irrespective of whether the institution acts as an originator or as an investor in securitisations backed by retail exposures.

5. Proportionate retail diversification
methods
10. For the purpose of Article 123(1), point (c) of Regulation (EU) No 575/2013, an exposure should
be considered as representing one of a significant number of exposures with similar characteristics, such that the risks associated with such exposure are substantially reduced, where it belongs to a sufficiently diversified portfolio in accordance with paragraph 11.
11. A portfolio should be considered sufficiently diversified where the ratio of the sum of the
exposure values of the large eligible retail exposures, as defined in paragraph 12, over the sum of the exposure values of all the institution’s eligible retail exposures does not exceed 10%.
12. An eligible retail exposure should be considered a large eligible retail exposure when the ratio
of its exposure value over the sum of the exposure values of all the institution’s eligible retail exposures exceeds the threshold of 0.2%. For the purpose of identifying large eligible retail exposures, the institution should treat the eligible retail exposures to a client or to a group of connected clients, as applicable, as a single exposure, summing their exposure values.
13. The institution should first assess whether the portfolio composed of all the institution’s eligible
retail exposures meets the condition set out in paragraph 11.
14. Where the portfolio composed of all the institution’s eligible retail exposures does not meet
the condition set out in paragraph 11, the institution may exclude from it one or more large eligible retail exposures as defined in paragraph 12.
15. The portfolio resulting from the exclusion of exposures carried out in accordance with
paragraph 14 should be considered as sufficiently diversified if it meets the condition set out in paragraph 11.
16. The exposures excluded in accordance with paragraph 14 should not be considered as
representing one of a significant number of exposures with similar characteristics for the purpose of Article 123(1), point (c) of Regulation (EU) No 575/2013.
17. In case of a portfolio including securitised exposures, the assessment of compliance with the
diversification condition referred to in paragraph 11 should be carried out with regard to the retail exposures underlying the securitisation as if those underlying exposures were not securitised, in accordance with Article 255(6) of Regulation (EU) No 575/2013. Therefore, the calculation of the ratios referred to in paragraphs 11 and 12 should not be done for the whole portfolio of the institution’s eligible retail exposures but should be done separately for three sub portfolios. More specifically:

18. Notwithstanding paragraph 17, for securitised exposures where institutions act as investors,

Article 123(1) of Regulation (EU) No 575/2013 as amended by Regulation (EU) 2024/1623 (CRR)
mandates the EBA to issue Guidelines to specify proportionate diversification methods under the Standardised Approach for credit risk under which the exposure should be considered as one of a significant number of exposures with similar characteristics; satisfactory diversification is one of the mandatory criteria set out under Article 123(1) of the CRR to be fulfilled for the application of a preferential risk weight of 75%. 9 As per Article 16(2) of the ESAs regulation (Regulation (EU) No 1093/2010, (EU) No 1094/2010 and (EU) No 1095/2010 of the European Parliament and of the Council), any guidelines developed by the ESAs should be accompanied by an Impact Assessment in the Annex which analyses ‘the potential related costs and benefits’ of the Guidelines. Such Annex should provide the reader with an overview of the findings as regards the problem identification, the options identified to remove the problem and their potential impacts. The EBA has prepared the Impact Assessment contained in the Guidelines, which analyses the policy options considered. Given the nature of the topic, the Impact Assessment is qualitative, and the limited data received during the consultation is not considered representative of the European context. Problem identification and baseline scenario The Basel III international accords determine the ‘diversification condition’ for retail exposures eligible to the 75% preferential risk weight as the ‘granularity criterion’, where it is noted that no aggregate exposure to one counterparty can exceed 0.2% of the overall portfolio excluding defaulted exposures, unless the national supervisor has determined another method to ensure satisfactory retail diversification. To retain the possibility that institutions which do not hold a granular enough retail portfolio can still apply the preferential risk weight, a diversification test is introduced that allows an objective quantitative assessment of no material correlation. The diversification test in its final, simplified version can be seen as a granularity test with additional flexibility, which does not impose significant additional burden on institutions, as it is based on already available information. In practice, Except 1) transactor exposures, which are assigned a risk weight of 45% and 2) exposures due to loans granted by an institution to pensioners or employees with a permanent contract against the unconditional transfer of part of the borrower’s pension or salary to that institution, which are assigned a risk weight of 35% when meeting the conditions set out in Article 123(5) of the CRR (Regulation (EU) No 575/2013 of the European Parliament and of the Council of 26 June 2013 on prudential requirements for credit institutions and investment firms and amending Regulation (EU) No 648/2012 (OJ L 176, 27.6.2013, p. 1, ELI: http://data.europa.eu/eli/reg/2013/575/oj). European üllQ Banking UUCI Authority

FINAL REPORT ON GUIDELINES ON PROPORTIONATE RETAIL DIVERSIFICATION METHODS institutions simply are to compare the share of their retail exposures that exceed the 0.2% granularity criterion to a pre-specified threshold. Larger institutions can be in a better position to have less concentrated retail portfolios, in case retail exposures are a relevant part of the business activities of this institution, and in such case are expected to meet the 0.2% granularity criterion more easily compared with smaller institutions. Thus, diversification concerns are limited for larger retail portfolios, and the introduced measure is of particular relevance and provides flexibility for those institutions with retail portfolios with obligors for which the total amount owed by all these obligors or groups of connected clients to the institution, its parent and its subsidiaries (other than for RRE) is lower than EUR 500 million. Policy objectives The main objective of these guidelines is to provide harmonised guidance at European level for appropriate retail diversification methods that are required to fulfil the mandatory criterion for satisfactory diversification for an exposure to be granted a preferential risk weight treatment and ultimately achieving a level playing field across the EU. In particular, this instrument should retain the possibility also for institutions that are not holding a granular enough retail portfolio to apply the preferential retail risk weights to that part of the portfolio, which is sufficiently diversified. Options considered In preparing the present guidelines, the EBA considered two policy options:
a. non-iterative process: Multiplying 0.2% by the sum of the exposure values of those exposures belonging to the original portfolio (i.e. to the portfolio without excluding any large) exposures); b. iterative process: Multiplying 0.2% by the sum of the exposure values of those exposures belonging to the final portfolio that is being assessed (i.e. the original portfolio after excluding any (large) exposures). Assessment of the options and the preferred option(s) Taking into account proportionality and ensuring strict prudential standards, the assessment considers (i) operational practicability, (ii) risk management incentives, and (iii) comparability across institutions. Under option a., exposures exceeding the 0.2% granularity criterion are retained in the denominator. The removal of exposures that exceed the 0.2% granularity criterion from the portfolio therefore automatically leads to satisfactory diversification. By applying a non-iterative process, the granularity criterion is only verified once, which avoids circular calculations as the denominator always refers to the original portfolio from which no exposures have been removed. European üllQ Banking UUCI Authority

FINAL REPORT ON GUIDELINES ON PROPORTIONATE RETAIL DIVERSIFICATION METHODS
I. Concerning (i): this option can be considered as a proportionate and harmonised
approach toward ensuring satisfactory retail diversification.
II. Concerning (ii): from a risk management perspective, this approach could
incentivise the construction of artificially large non-granular retail exposures that inflate the denominator as reference is only made to the original portfolio. While incentives for such practices could be limited to a certain extent as the institution would have to bear the cost of such artificial exposure inflation in terms of RWEA, these capital costs might, however, rather not be sufficient for discouraging this regulatory arbitrage, due to being relatively minor compared to the reduction in capital costs for the difference between a 100% risk weight and the preferential retail risk weight, in particular if unconditionally cancellable commitments with only 10% conversion factor are used for this purpose.
III. Concerning (iii): from a comparability perspective, the approach would treat the
same portfolios differently for different banks, depending on the existence of excluded exposures, as the reference is always to the original portfolio. While excluding large eligible retail exposures allows bank A to treat the whole remaining portfolio as sufficiently diversified, this remaining portfolio might be identical with the original portfolio of another bank B which, however, would need to exclude additional large eligible retail exposures under option a. Under option b., exposures exceeding the 0.2% granularity criterion are removed from the denominator. Put differently, the denominator is updated to reflect removed exposures and exposures, which will belong to the eligible retail portfolio. The removal of exposures that exceed the 0.2% granularity criterion from the portfolio does not necessarily lead to satisfactory diversification for the remaining portfolio. For this reason (i.e. updating the denominator), the iterative nature of this option comes into play to determine the retail exposures that are eligible for the preferential risk weight. Generally, it should be noted that, by construction, the resulting granularity is systematically higher with this option than with option a., as the denominator becomes smaller due to the iterative process.
I. Concerning (i): this option can also be considered as a proportionate and
harmonized approach toward ensuring satisfactory retail diversification, but its implementation is more complex due to the iterative process. However, since this approach is also based solely on readily available information, the additional burden can be deemed relatively modest.
II. Concerning (ii) and (iii): from a risk management and comparability perspective,
this option does not incentivise an artificial inflation of exposures and treats the same portfolios equally as the denominator takes into account the excluded exposures. European üllQ Banking UUCI Authority

FINAL REPORT ON GUIDELINES ON PROPORTIONATE RETAIL DIVERSIFICATION METHODS Following also the feedback received during the consultation, the retained option is option a., as it provides a proportionate, operationally simple, and harmonised approach, while still ensuring satisfactory retail diversification with acceptable prudential safeguards for exposures to be granted a preferential risk weight of 75% as set out under Article 123(1) of the CRR. Feedback on the public consultation The EBA publicly consulted on the draft proposal contained in this paper. The consultation period lasted for three months and ended on 12 February 2025. Thirteen answers have been received on a non-confidential basis, which were published on the EBA website, and one on a confidential basis. This paper presents a summary of the key points and other comments arising from the consultation, the analysis and discussion triggered by these comments and the actions taken to address them if deemed necessary. In many cases several industry bodies made similar comments, or the same body repeated its comments in the response to different questions. In such cases, the comments and EBA analysis are included in the section of this paper where EBA considers them most appropriate. Following the responses received during the public consultation, the draft has been revised to move from the iterative approach to the one-step approach, which is considered, among other things, simpler to implement. In addition, the threshold has been increased, from 5% to 10%, compared to the consultation phase, in order to alleviate the impact on small and mediumsized institutions. European üllQ Banking UUCI Authority

Summary of responses to the consultation and the EBA’s analysis General comments Preferred methodology (iterative vs. one-step) Respondents, particularly from small and medium-sized institutions, generally favoured the one-step approach due to its simplicity and lower operational burden. The iterative method was seen as overly complex, requiring multiple recalculations, and was considered disproportionately demanding for smaller entities. Many respondents also called for an increase in the threshold from 5% to 10% under the one-step approach, noting that the lower threshold could significantly hinder access to the preferential risk weight and negatively affect lending capacity, especially to SMEs. Some suggested alternative criteria, such as absolute thresholds (e.g. 1,000 retail loans) or qualitative measures, although these were not clearly defined. Taking into account the feedback received during the public consultation, the EBA decided to accommodate the industry's requests to a certain extent by converging on the adoption of the one-step approach. This method was generally preferred by respondents, particularly small and medium-sized institutions, for its greater simplicity and operational ease compared to the iterative approach. To alleviate the capital impact on smaller institutions, the EBA decided to set the diversification threshold at 10%. This calibration strikes a balance between facilitating the implementation for institutions and preserving sufficient granularity in the retail portfolio to control concentration risk in line with prudential standards. One-step approach with 10% threshold Frequency, basis and level of calculation Respondents questioned the need for quarterly testing, stating that it would impose Despite industry concerns, the EBA supported maintaining the quarterly frequency, using None European ûflQ Banking UUU Authority

a heavy operational burden, especially when combined with the iterative approach. Thus, they propose limiting the calculation to yearend to reduce complexity. In addition, submitters suggest using the ‘amount owed’ instead of exposure at default (EAD) to assess portfolio diversification, aligning with
Article 123(1)(b). Finally, submitters find dual
assessment at both individual and consolidated levels is not only overly complex but also prone to inconsistencies. They recommend performing the test solely at consolidated level. exposure at default (EAD) as the basis for calculation and performing the test both at individual and consolidated level. Regarding the industry requests for a reduction in frequency, the EBA recognised that regular quarterly calculations are important to ensuring ongoing portfolio granularity, especially in light of potential fluctuations in the composition of retail exposures throughout the year. Further, the EBA considers that using exposure at default (EAD) reflects the exposure value defined at facility level, in line with the Basel standards. Moreover, EBA does not consider the test to be particularly burdensome, as once it is implemented at IT level, it should not pose an issue to perform it at each reporting date alongside the RWA calculation. Finally, the policy decision regarding the level of calculation is grounded in the principles outlined in the CRR, which require own funds requirements to apply at both levels. Treatment of securitised exposures One association raised the issue of how securitised exposures should be treated within the retail diversification test. They noted the difficulty of applying the test to securitisation The EBA acknowledges the complexity of such cases and has made explicit the approach in the final Guidelines. In particular, the Guidelines require institutions to carry out the assessment Treatment for securitised exposure made explicit European ûflQ Banking UUU Authority

pools, particularly when banks act as investors or retain only a portion of the securitised loans. of the diversification condition separately for three sub-portfolios:

First, for the sub-portfolio consisting of
non-securitised exposures, the numerator and denominator should include only non-securitised eligible retail exposures.
Second, for securitised exposures where
the institution acts as originator, the numerator and denominator should include both those securitised exposures and all non-securitised eligible retail exposures.
Third, for securitised exposures where
the institution acts as investor, the numerator and denominator should include only the underlying securitised exposures. Finally, to accommodate operational limitations, an alternative provision is introduced for securitised exposures where institutions act as investors. In such cases, the diversification European ûflQ Banking UUU Authority

assessment is deemed to be fulfilled when the securitisation positions are backed by underlying exposures for which information on the obligor and on the exposure value is not available in the templates referred to in Article 7 of Regulation (EU) 2017/2402, in line with the due diligence and transparency requirements set out in Articles 5 and 7 of that Regulation. This derogation applies only for as long as the templates mandated under Article 7(4) of Regulation (EU) 2017/2402 do not include such information. Responses to questions in Consultation Paper EBA/CP /2024/22 Question 1. What is the percentage of exposures within your retail portfolio that are part of a group of connected clients? Only two associations provide data. - European ûflQ Banking UUU Authority

Question 2. Do you identify any implementation issue in implementing the diversification method? Most associations highlighted that the proposed diversification method is particularly burdensome. Refer to the EBA analysis in the ‘General Comment’ section. Question 3. Which methods do you currently use to assess retail diversification? Please elaborate. The majority of medium-large banks use the 0.2% criterion, a quantitative measure, while small banks, in particular, mainly use qualitative criteria. The qualitative criteria were not further specified. Refer to the EBA analysis in the ‘General Comment’ section. Question 4. Under the proposed approach, in the first step of the calculation before any exclusion, what is the share in terms of exposure value of the large eligible retail exposures as defined under the proposed approach compared to all the eligible retail exposures? Only four institutions provide data. Question 5. What is the impact of the proposed It was highlighted that the proposed diversification tests could disproportionately European ûflQ Banking UUU Authority
