            COMMISSION DELEGATED REGULATION (EU) 2025/1311
of 3 July 2025
         
supplementing Regulation (EU) No 575/2013 of the European Parliament and of the Council with regard to regulatory technical standards specifying the conditions for assessing the materiality of extensions of, and changes to, the use of alternative internal models, and changes to the subset of the modellable risk factors
(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 the European Parliament and of the Council of 26 June 2013 on prudential requirements for credit institutions and amending Regulation (EU) No 648/2012 (1), and in particular Article 325az(8), first subparagraph, point (a), and third subparagraph thereof,

Whereas:







(1)


Whether institutions obtain permission from their competent authorities to use the alternative internal model approach laid down in Title IV, Chapter 1b, of Regulation (EU) No 575/2013 depends on whether those institutions comply with the requirements set out in Part Three, Title IV, Chapter 1b of that Regulation, including requirements as regards methods, processes, controls, data collection, organisation of the risk control unit and internal validation function, and IT systems. Institutions are allowed to modify the methods, processes, controls, data collection, organisation of the risk control unit and internal validation function, and IT systems, as approved by their competent authorities, provided that such modifications have been notified to their competent authority or have been approved by their competent authority, depending on the nature of the modifications, in accordance with Article 325az(7) of Regulation (EU) No 575/2013. That also applies to modifications triggered by the application of regulatory requirements, where those modifications encompass the use of methods or approaches that are not part of the existing competent authority’s permission.












(2)


The choice of the subset of the modellable risk factors referred to in Article 325bc(2) of Regulation (EU) No 575/2013 is a part of the institution’s approved and documented set of internal policies and procedures. Where the institution modifies its policies and procedures related to the choice of modellable risk factors, that modification should be approved by or notified to the competent authority, as it constitutes a change to the choice of the subset of the modellable risk factors. By contrast, changes to the composition of the list of risk factors included in the subset of modellable risk factors referred to in Article 325bc(2) of that Regulation, which take place within the approved policies and procedures, including in the case of a reduction in data availability, should not be considered as changes to the institution’s choice of the subset of modellable risk factors.












(3)


The permission from the competent authority relates to the methods, processes, controls, data collection and IT systems of the alternative internal model approach. Therefore institutions should not be required to notify their competent authority of ongoing alignments of the alternative internal models they use to the data sources used, of the correction of errors, or of minor adjustments that are necessary for the day-to-day maintenance of the models, that occur within the already approved methods, processes, controls, data collection and IT systems and are recorded accordingly.












(4)


Extensions and changes to the use of alternative internal models, or changes to the subset of the modellable risk factors, should be classified as ‘material’, and thus as requiring prior permission by competent authorities, or ‘non-material’ and thus requiring notification to competent authorities, on the basis of both qualitative and quantitative criteria. Some extensions and changes, including organisational changes, internal process changes, or risk management process changes, may not have a direct quantitative impact on the alternative internal models, but may influence the accuracy, soundness and use of the that alternative internal model. In those cases, given the difficulty of determining a quantitative impact, institutions and competent authorities should use only the qualitative criteria for the assessment of the materiality of those changes.












(5)


To ensure a prudent approach and enable competent authorities to review extensions of, and changes to, the use of alternative internal models, or changes to the subset of the modellable risk factors, before they are implemented, institutions should notify their competent authority of such non-material extensions and changes at least four weeks before implementation. However, that notice period should not apply to cases where institutions fail to meet the condition set out in Article 325bc(2), point (a), of Regulation (EU) No 575/2013. In such cases, institutions should have the possibility to take immediate action to restore compliance with the regulatory requirements, but should also duly and promptly notify competent authorities before implementing this change.












(6)


Competent authorities can only review extensions of, and changes to, the use of alternative internal models, and changes to the subset of the modellable risk factors, where they receive from the institutions concerned all information necessary for such a review. It is therefore necessary to specify the content of the information that institutions are to provide for that purpose.












(7)


The quantitative metrics and related thresholds used to identify material changes and extensions should be designed in a way that they take into account the impact on some relevant risk numbers and on the combined market risk capital requirements. To facilitate the computation of those quantitative metrics and ensure the most informative results, only the most recent risk numbers should be considered.












(8)


To take into account the effect of possible large changes to trading book positions, which typically happen on a daily basis, institutions should calculate the required risk numbers on the basis of an observation period of 15 consecutive business days, rather than on the basis of a single point in time. However, to include a certain degree of proportionality in the assessment of whether changes to the use of alternative internal models and changes to the subset of the modellable risk factors are material, that observation period of 15 consecutive business days should be subject to exemptions where the assessed quantitative impact is very minor on the first testing date and where there is a presumption that the quantitative thresholds will not be breached during that 15 consecutive business days period.












(9)


Competent authorities should not require institutions to calculate the required risk numbers when they grant institutions the initial permission to calculate their own funds requirements by using alternative internal models. However, to justify and substantiate the materiality assessment of those changes and extensions, institutions should calculate the required risk numbers when they extend or change their alternative internal models and change the subset of the modellable risk factors.












(10)


To ensure that competent authorities take, at any time, appropriate supervisory measures with regard to extensions and changes to the alternative internal models and changes to the institution’s choice of the subset of the modellable risk factors, they should consider a group of related extensions or changes to an alternative internal model notified separately by an institution as a single extension or change. In such a case, competent authorities should assess whether extensions and changes to the use of the alternative internal models are material at the level of that single extension or change.












(11)


This Regulation is based on the draft regulatory technical standards submitted to the Commission by the European Banking Authority.












(12)


The European Banking Authority 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),

CHAPTER 3


General provisions for assessing the materiality of changes to and extensions of the use of the alternative internal models, and of changes to the institution’s choice of the subset of modellable risk factors



Article 7

Principles for the classification of changes to, and extensions of, the use of alternative internal models, and of changes to the subset of the modellable risk factors


1.   When calculating the quantitative impacts in accordance with Article 2(1) and (2), Article 3(1) and (2), Article 5(1) and Article 6(1), institutions shall use the most recent model setup and calibration and the data inputs corresponding to the period referred to in Article 2(9).
No calculation requirements shall apply to extensions and changes having no direct quantitative impact.


2.   Competent authorities shall consider several modifications to the alternative internal model, separately submitted by an institution, as a single model extension or change where such modifications are similar in nature or related in scope. Competent authorities shall consider groups of modifications to the alternative internal model, submitted as a single model extension or change, as separate model extensions or changes where such modifications to the model are not similar in nature or related in scope.


3.   In case of doubt on the categorisation referred to in Articles 1 or 4, institutions shall provide the competent authority with an explanatory note justifying their choices of category or sub-category and presenting possible alternatives. The competent authority may change the category or sub-category provided in the request for a permission as referred to in Article 325az(7), first subparagraph, of Regulation (EU) No 575/2013, or the notification as referred to in Article 325az(7), second subparagraph, of that Regulation.



Article 8

Implementation of changes to, and extensions of, the use of alternative internal models, and of changes to the subset of the modellable risk factors


1.   Institutions that have been granted a permission for a material extension of, or change to, the use of alternative internal models, or a material change to the subset of the modellable risk factors, as referred to in Article 325az(7), first subparagraph, of Regulation (EU) No 575/2013, shall calculate their own funds requirements based on the approved extension or change from the date specified in the permission.


2.   In case of a delay of the implementation of an extension or change to the use of alternative internal models or a change to the subset of the modellable risk factors for which a competent authority has granted a permission as referred to in Article 325az(7), first subparagraph, of Regulation (EU) No 575/2013, institutions shall, without undue delay:






(a)


notify their competent authority of such a delay;










(b)


submit to their competent authority a plan for a timely implementation of the approved extension or change, to be approved by the competent authority.






3.   Institutions that have notified their competent authority of an extension or change and have subsequently decided not to implement such extension or change, shall notify their competent authority thereof without undue delay.



Article 9

Documentation of extensions and changes to the use of the alternative internal models and changes to the institution’s choice of the subset of modellable risk factors


1.   Institutions shall, when they ask their competent authority for a permission as referred to in Article 325az(7), first subparagraph, of Regulation (EU) No 575/2013, provide their competent authority, with all of the following documentation:






(a)


a description of the extension or change to the use of their alternative internal models, or of the change to their choice of the subset of modellable risk factors, and a description of the rationale and objective of that extension or change;










(b)


the implementation date of such extension or change;










(c)


the scope of trading desks affected by the extension or change to the use of the alternative internal model or the change to the institution’s choice of the subset of modellable risk factors including information on the trading volume of those desks;










(d)


technical and process documents;










(e)


reports of the institutions’ independent review or validation;










(f)


a confirmation that the competent body of the institution has, through the institution’s approval processes, approved the extension or change to the use of the alternative internal model or the change to the institution’s choice of the subset of modellable risk factors, and the date of that approval;










(g)


where applicable, any relevant one of the following, together with a justification of representativeness of the period of 15 consecutive business days selected for the quantitative impact:

ANNEX
PART I

Extensions and changes requiring competent authorities’ permission (‘material’)









1.


Significant changes to the structure or organisation of an institution’s trading desks, for which permission has been granted to calculate the own funds requirements for market risk by using alternative internal models, including significant changes to the booking models, to the risk management structure or to the business strategy, including any of the following cases:






(a)


significant changes where the institution aims to apply internal risk transfers for the first time;










(b)


significant changes where trading desks capture foreign exchange (FX) or commodity risk in the non-trading book for the first time;










(c)


significant changes where trading desks start to include positions in asset classes different from those forming part of the permission to use the alternative internal models.
















2.


Inclusion in the scope of the alternative internal model approach of a trading desk, which, at the moment of the request for a permission as referred to in Article 325az(7), first subparagraph, of Regulation (EU) No 575/2013, is not part of the permission to calculate the own funds requirements for market risk by using alternative internal models, and which fulfils any of the following conditions:






(a)


for that trading desk, front office systems or IT systems that are different from those forming part of the permission to use the alternative internal models are used;










(b)


that trading desk is located in a third country jurisdiction where, at the moment of the request, no trading desk in the scope of the alternative internal models is located;










(c)


that trading desk entails positions in asset classes that are different from those forming part of the permission to use the alternative internal models.
















3.


Changes to the fundamental approach to calculate the partial expected shortfall measures referred to in Article 325bb(1) of Regulation (EU) No 575/2013, including between historical simulation, parametric or Monte Carlo approach.












4.


Changes to the fundamental approach to calculate the own funds requirement for default risk referred to in Article 325ba(2) of Regulation (EU) No 575/2023, including significant changes to the choice of the systematic risk factors or to the correlation structure of the model.




PART II

Extensions and changes requiring notification with additional information









1.


The inclusion in the scope of a trading desk under the alternative internal models of product classes requiring other risk modelling techniques than those forming part of the permission to use those alternative internal models, such as path-dependent products, or multi-underlying positions, including cases where a change in booking models leads to products for which the institution was transferring the market risk to another entity of the group outside the scope of the highest level of consolidation within the Union at the time when permission for internal models was granted start being risk-managed in the institution.












2.


Changes to the structure or organisation of an institution’s trading desks consisting of the merging or the splitting of desks for which permission has been granted to calculate the own funds requirements for market risk by using the alternative internal models, provided that those changes do not meet the conditions set out in Article 2 of this Regulation.












3.


Changes to the methodology used to assess the modellability of risk factors in accordance with Article 325be of Regulation (EU) No 575/2013.












4.


Changes to the methodology for calculating actual or hypothetical profit and loss, where such changes have the effect of reducing the number of overshootings of a trading desk for which permission has been granted to use alternative internal models, restoring its compliance with the conditions on back-testing referred to in Article 325bf(3) of Regulation (EU) No 575/2013.












5.


Changes to the methodology for calculating hypothetical or theoretical profit and loss, where such changes have the effect of increasing the Spearman correlation coefficient or reducing the Kolmogorov-Smirnov test metric of a trading desk for which permission has been granted to use alternative internal models, changing its classification as laid down in Article 9 of Commission Delegated Regulation (EU) 2022/2059 (1), for the purpose of meeting the P&L attribution requirements set out in Article 325bg of Regulation (EU) No 575/2013.












6.


Fundamental changes to the internal validation methodology referred to in Article 325bj of Regulation (EU) No 575/2013 which lead to significant changes in the way the institution assesses the overall performance and integrity of the alternative internal models, including:






(a)


where the scope of the internal validation review, its frequency or the quantity or quality of the tests and controls performed are reduced;










(b)


where there are significant changes to the decision-making process in place to ensure that the findings and recommendations resulting from the validation process are properly taken into account by the senior management of the institution.
