In an earlier report², the EBA defined ESG-related risks as “the risks of any negative financial impact on the institution stemming from the current or prospective impacts of ESG factors on its counterparties or invested assets”. Hence, the focus is not on the direct impact of ESG factors on the institution, but on the indirect impact through the exposure of counterparties and invested assets to ESG-related risks. The EBA report also provides examples for typical ESG-related factors.
While the ITS have been streamlined and simplified compared to the consultation paper published in March 2021, there are plenty of challenges remaining for banks to implement these standards.

Development of the ITS

The EBA has been mandated to develop the ITS on P3 disclosures on ESG risks in Article 434a of the Capital Requirements Regulation (CRR). The EBA has opted for a sequential approach, with an initial focus on climate change-related risks. This is further narrowed down by only considering the banking book. The short maturity and fast revolving positions in the trading book are out of scope for now. The scope of the ITS will be extended to included other environmental risks (like loss of biodiversity), and social and governance risks, in later stages.

In the development of the ITS, the EBA has strived for alignment with several other regulations and initiatives on climate-related disclosures that apply to banks. The most notable ones are listed below (and in Figure 1):

Figure 1 – Overview of related regulations and initiatives considered in the development of the ITS

• Capital Requirements Directive and Regulation (CRD and CRR): article 98(8) of the CRD³ mandated the EBA to publish the EBA report on Management and Supervision of ESG risks, which includes the split of climate change-related risks in physical and transition risks. Article 434a of the CRR⁴ mandated the EBA to develop the draft ITS to specify the ESG disclosure requirements described in article 449a.
• EBA report on Management and Supervision of ESG risks²: the report provides common definitions of ESG risks and contains proposals on how to include ESG risks in the risk frameworks of banks, covering its identification, assessment, and management. It also discusses the way to include ESG risks in the supervisory review process.
• Task Force on Climate-related Financial Disclosures (TCFD)⁵: the Financial Stability Board’s TFCD has published recommendations on climate-related disclosures. The metrics and Key Performance Indicators (KPIs) included in the ITS have been aligned with the TCFD recommendations.
• Taxonomy Regulation⁶: the European Union’s common classification system of environmentally sustainable economic activities is underpinning the main KPIs introduced in the ITS.
• Climate Benchmark Regulation (CBR)⁷: In the CBR, two types of climate benchmarks were introduced (‘EU Climate Transition’ and ‘EU Paris-aligned’ benchmarks) and ESG disclosures for all other benchmarks (excluding interest rate and currency benchmarks) were required.
• Non-Financial Reporting Directive (NFRD)⁸: the NFRD introduces ESG disclosure obligations for large companies, which include climate-related information.
• Corporate Sustainability Reporting Directive (CSRD)⁹: a proposal by the European Commission to extend the scope of the NFRD to also include all companies listed on regulated markets (except listed micro-enterprises). One of the ITS’s KPIs, the Green Asset Ratio (GAR) is directly linked to the scope of the NFRD/CSRD.
• Sustainable Finance Disclosure Regulation (SFDR)¹⁰: the SFDR lays down sustainability disclosure obligations for manufacturers of financial products and financial advisers towards end-investors. It applies to banks that provide portfolio management investment advice services.

Compared to the consultation paper for the ITS, several changes have been made to the required templates. Some templates have been combined (e.g., templates #1 and #2 from the consultation paper have been combined into template #1 of the final draft ITS) and several templates have been reorganized and trimmed down (e.g., the requirement to report exposures to top EU or top national polluters has been removed).

Quantitative disclosures

The ITS on P3 disclosure on ESG risks introduce ten templates on quantitative disclosures. These can be grouped in four templates on transition risks, one on physical risks, and five on mitigating actions:

• Transition risks
  Two of the required templates are relatively straightforward. Banks need to report the energy efficiency of real estate collateral in the loan portfolio (#2) and report their aggregate exposure to the top 20 of the most carbon-intensive firms in the world (#4).
  The main challenge for banks though will be in completing the other two templates:
  • Template #1 requires banks to disclose the gross carrying amount of loans and advances provided to non-financial corporates, classified by NACE sector codes and residual maturities. It is also required to report on the counterparties’ scope 1, 2, and 3 greenhouse gas (GHG) emissions. Reflecting the challenge in reporting on scope 3 emissions, a transitional measure is in place. Full reporting needs to be in place by June 2024. Until then, banks need to report their available estimates (if any) and explain the methodologies and data sources they intend to use.
  • In the last template (#3), banks also need to report scope 3 emissions, but relate these to the alignment metrics defined by the International Energy Agency (IEA) for the ‘net zero by 2050’ scenario. For this scenario, a target for a CO2 intensity metric is defined for 2030. By calculating the distance to this target, it becomes clear how banks are progressing (over time) towards supporting a sustainable economy. A similar transitional measure applies as for template #1.
• Physical risks
  In template #5, banks are required to disclose how their banking book positions are exposed to physical risks, i.e., “chronic and acute climate-related hazards”. The exposures need to be reported by residual maturity and by NACE sector codes and should reflect exposure to risks like heat waves, droughts, floods, hurricanes, and wildfires. Specialized databases need to be consulted to compile a detailed understanding of these exposures. To support their submissions, banks further need to compile a narrative that explains the methodologies they used.
• Mitigating actions
  The final set of templates covers quantitative information on the actions a bank takes to mitigate or adapt to climate change risks.
  • Templates #6-8 all relate to the GAR, which indicates what part of the bank’s banking book is aligned with the EU’s Taxonomy:
    • In template #7, banks need to report the outstanding banking book exposures to different types of clients/issuers, as well as the amount of these exposures that are taxonomy-eligible (that is, to sectors included in the EU Taxonomy) and taxonomy-aligned (that is, taxonomy-eligible exposures financing activities that contribute to climate change mitigation or adaptation). Based on this information, the bank’s GAR can be determined.
    • In template #8, a GAR needs to be reported for the exposures to each type of client/issuer distinguished in template #7, with a distinction between a GAR for the full outstanding stock of exposures per client/issuer type, and a GAR for newly originated (‘flow’) exposures.
    • Template #6 contains a summary of the GARs from templates #7 and #8.
      In these templates, the numerator of the GAR only includes exposures to non-financial corporations that are required to publish non-financial information under the NFRD. Any exposures to other corporate counterparties therefore are considered 0% Taxonomy-aligned.
  • The main challenge in this group of templates is in template #9. To incentivize banks to support all of their counterparties to transition to a more sustainable business model, and to collect ESG data on these counterparties, the EBA introduces the Banking Book Taxonomy Alignment Ratio (BTAR). In this metric, the numerator does include the exposures to counterparties that are not subject to NFRD disclosure obligations. The BTAR ratios obtained from the information in template #9 therefore complement the GAR ratios obtained in templates #7 and #8.
  • In the final template (#10), banks have the opportunity to include any other climate change mitigating actions that are not covered by the EU Taxonomy. They can for example report on their use of green or sustainable bonds and loans.

An overview of the templates for quantitative disclosures in presented in Figure 2.

Qualitative disclosures

In the ITS on P3 disclosures on ESG risks, three tables are included for qualitative disclosures. The EBA has aligned these tables with their Report on Management and Supervision of ESG risks¹¹. The three tables are set up for qualitative information on environmental, social, and governance risks, respectively. For each of these topics, banks need to address three aspects: on business strategy and processes, governance, and risk management. An overview of the required disclosures is presented in Figure 3.

Figure 3 – Overview of qualitative ESG disclosures (based on templates & section 2.3.2 of the EBA ITS on P3 disclosures on ESG risks)

Timelines and transitional measures

The ITS on P3 disclosure on ESG risks become effective per 30 June 2022 for large institutions that have securities traded on a regulated market of an EU member state. A semi-annual disclosure is required, but the first disclosure is annual. Consequently, based on 31 December 2022 data, the first reporting will take place in the first quarter of 2023.

The EBA has introduced a number of transitional measures. These can be summarized as follows:

• The reporting of information on the GAR is only required as of 31 December 2023.
• The reporting of information on the BTAR, the bank’s financed scope 3 emissions, and the alignment metrics is only required as of June 2024.

The EBA has further indicated in the ITS that they will conduct a review of the ITS’s requirements during 2024. They may then also extend the ITS with other environmental risks (other than the climate change-related risks in the current version). The EU Taxonomy is expected to cover a broader range of environmental risks by the end of 2022. Sometime after 2024, it is expected that the EBA will further extend the ITS by including disclosure requirements on social and governance risks.

An overview of the main timelines and transitional measures is presented in Figure 4.

Conclusion

Society, and consequently banks too, are increasingly facing risks stemming from changes in our climate. In recent years, supervisory authorities have stepped up by introducing more and more guidance and regulation to create transparency about climate change risk, and more broadly ESG risks. The publication of the ITS on P3 disclosures on ESG risks by the EBA marks an important milestone. It offers banks the opportunity to disseminate a constructive and positive role in the transition to a sustainable economy.

Nonetheless, implementing the disclosure requirements will be a challenge. Developing detailed assessments of the physical risks to which their asset portfolio is exposed and to estimate the scope 3 emissions of their clients and counterparties (‘financed emissions’) will not be straightforward. For their largest counterparties, banks will be able to profit from the NFRD disclosure obligations, but especially in Europe a bank’s portfolio typically has many exposures to small- and medium-sized enterprises. Meeting the disclosure requirements introduced by the EBA will require timely and intensive discussions with a substantial part of the bank’s counterparties.

Banks also need to provide detailed information on how ESG risks are reflected in the bank’s strategy and governance and incorporated in the risk management framework. With our extensive knowledge on market risk, credit risk, liquidity risk, and business risk, Zanders is well equipped to support banks with integrating the identification, measurement, and management of climate change-related risks into existing risk frameworks.

This new update is triggered by the revised Capital Requirements Regulation (CRR2) and Capital Requirements Directive (CRD5). Both documents were adopted by the Council of the EU and the European Parliament in 2019 as part of the Risk Reduction Measures package. The CRR2 and CRD5 included numerous mandates for the EBA to come up with new or adjusted technical standards and guidelines. These are now covered in three separate consultation papers

1. The first consultation paper¹ describes the update of the IRRBB Guidelines themselves.
2. The second paper² concerns the introduction of a standardized approach (SA) which should be applied when a competent authority deems a bank’s internal model for IRRBB management non-satisfactory. It also introduces a simplified SA for smaller and non-complex institutions.
3. The third consultation paper³ offers updates to the supervisory outlier test (SOT) for the Economic Value of Equity (EVE) and the introduction of an SOT for Net Interest Income (NII). Read our analysis on this consultation paper here »

In this article we focus on the first consultation paper. The update of the IRRBB Guidelines can be split up in three topics and each will be discussed in further detail:

• Additional criteria for the assessment and monitoring of the credit spread risk arising from non-trading book activities (CSRBB)
• The criteria for non-satisfactory IRRBB internal systems
• A general update of the existing IRBBB Guidelines

CSRBB

The 2018 IRRBB Guidelines introduced the obligation for banks to monitor CSRBB. However, the publication did not describe how to do this. In the updated consultation paper the EBA defines the measurement of CSRBB as a separate risk class in more detail. The general governance related aspects such as (management) responsibilities, IT systems and internal reporting framework are separately defined for CSRBB, but are similar to those for IRRBB.

Also similar to IRRBB is that banks must express their risk appetite for CSRBB both from an NII as well as an economic value perspective.

The EBA defines CSRBB as:

“The risk driven by changes of the market price for credit risk, for liquidity and for potentially other characteristics of credit-risky instruments, which is not captured by IRRBB or by expected credit/(jump-to-) default risk. CSRBB captures the risk of an instrument’s changing spread while assuming the same level of creditworthiness, i.e. how the credit spread is moving within a certain rating/PD range.”

EBA

Compared to the previous definition, rating/PD migrations are explicitly excluded from CSRBB. Including idiosyncratic spreads could lead to double counting since these are generally covered by a credit risk framework. However, the guidelines give some flexibility to include idiosyncratic spreads, as long as the results are more conservative than when idiosyncratic spreads are excluded. This is because, based on the Quantitative Impact Study of December 2020 (QIS 2020), banks indicated to find it difficult to separate the idiosyncratic spreads from the credit spread.

Also, the scope of CSRBB has changed from the current IRRBB Guidelines. All assets, liabilities and off-balance-sheet items in the banking book that are sensitive to credit spread changes are within the scope of CSRBB whereas the 2018 IRRBB Guidelines focused only on the asset side. Based on the results of the QIS 2020, the EBA concluded that most of the exposures to CSRBB are debt securities which are accounted for at fair value (via Profit and Loss or Other Comprehensive Income). However, this does not rule out that other assets or liabilities could be exposed to CSRBB. It is stated that banks cannot ex-ante exclude positions from the scope of CSRBB. Any potential exclusion of instruments from the scope of CSRBB must be based on the absence of sensitivity to credit spread risk and appropriately documented. At a minimum, banks must include assets accounted at fair value in their scope.

We believe that the obligation to report CSRBB for all assets accounted for at fair value will be challenging for exposures that do not have quoted market prices. Without a deep liquid market, it will be difficult to establish the credits spread risk (even when idiosyncratic risk is included).

Another possible candidate to be included in the scope of CSRBB is the issued funding on the liability side of the banking book, especially in a NII context. When market spreads increase, this could become harmful when the wholesale funding needs to be rolled over against higher credit spread without being able to increase client interest on the asset side. Similar to IRRBB, the exposure to this risk depends on the repricing gap of the assets and liabilities. In this case, however, swaps cannot be used as hedge.

Other products such as consumer loans, mortgages, and consumer deposits, which are typically accounted for at amortized cost, are less likely to be included. This is also stated by the BCBS standards. The BCBS states that the margin (administrative rate) is under absolute control of the bank and hence not impacted by credit spreads. However, it is unclear whether this is sufficient to rule these products out of scope.

Non-satisfactory IRRBB internal systems

The EBA is mandated to specify the criteria for determining an IRRBB internal system as non-satisfactory. The EBA has identified specific items for this that should be considered. At a minimum, banks should have implemented their internal system in compliance with the IRRBB Guidelines, taking into account the principle of proportionality. More specifically:

• Such a system must cover all material interest rate risk components (gap risk, basis risk, option risk).
• The system should capture all material risks for significant assets, liabilities and off-balance sheet type instruments (e.g. non-maturing deposits, loans, and options).
• All estimated parameters must be sufficiently back tested and reviewed, considering the nature, scale and complexity of the bank.
• The internal system must comply with the model governance and the minimum required validation, review and control of IRRBB exposures as detailed by the IRRBB guidelines.
• Competent authorities may require banks to use the standardized approach³ if the internal systems are deemed non-satisfactory.

General update of existing IRRBB Guidelines

Major parts of the guidelines for managing IRRBB have not changed. In the section on IRRBB stress testing, however, a new article (#103) for products with significant repricing restrictions (e.g. an explicit floor on non-maturing deposits – NMDs) is introduced. As part of their stress testing, banks should consider the impact when these products are replaced with contracts with similar characteristics, even under a run-off assumption. The exact intention of this article is unclear. For NII-purposes it is common practice to roll over products with similar characteristics (or use another balance sheet development assumption). Our interpretation of this article is that banks are expected to measure the risk of continued repricing restrictions in an economic value perspective when the maturity of those funding sources is smaller than the maturity of the asset portfolio. This may for example materialize when banks roll over NMDs that are subject to a legally imposed floor.

Another update is the restriction on the maximum weighted average repricing maturity of five years for NMDs. This cap was prescribed for the EVE SOT and is now included for the internal measurement of IRRBB. We believe that the impact of this will be limited since only a few banks will have separate NMD models for internal measurement and the SOT.

Finally, some minor additions have been included in the guidelines. For example, the guidelines emphasize multiple times that when diversification assumptions are used for the measurement of IRRBB, these must be appropriately stressed and validated.

Conclusion

It is expected that the final guidelines will not deviate significantly from the consultation paper. Banks can therefore start preparing for these new expectations. For the measurement of IRRBB, limited changes are introduced in the consultation. Although the exact intention of the EBA is unclear to us, it is interesting to notice that the updated IRRBB Guidelines include the expectation that banks pay special attention in their stress tests to products with significant repricing restrictions. Furthermore, banks must invest in their CSRBB measurement. For their entire banking book, banks need to assess whether market wide credit spread changes will have an impact on an NII and/or economic value perspective. The scope of CSRBB measurement may need to be extended to include the funding issued by the bank. And to conclude, the obligation to measure CSRBB for fair value assets that do not have quoted market prices will be a challenge for banks.

The current version of the IRRBB Guidelines, published in 2018, came into force on 30 June 2019. At that time, the IRRBB Guidelines were aligned with the Standards on interest rate risk in the banking book, published by the Basel Committee on Banking Supervision (in short, the BCBS Standards) in April 2016.

The new updates are triggered by the revised Capital Requirements Regulation (CRR2) and Capital Requirements Directive (CRD5). Both documents were adopted by the Council of the EU and the European Parliament in 2019 as part of the Risk Reduction Measures package. The CRR2 and CRD5 included numerous mandates for the EBA to come up with new or adjusted technical standards and guidelines. These are now covered in three separate consultation papers:

1. The first consultation paper_¹ describes an update of the IRRBB Guidelines themselves. The main changes are the specification of criteria to identify “non-satisfactory internal models for IRRBB management” and the specification of criteria to assess and monitor Credit Spread Risk in the Banking Book (CSRBB). Read our analysis on this consultation paper here »
2. The second paper² concerns the introduction of a standardized approach (SA) which should be used when a competent authority deems a bank’s internal model for IRRBB management non-satisfactory. It also introduces a Simplified SA for smaller and non-complex institutions.
3. The third consultation paper³ offers updates to the supervisory outlier test (SOT) for the Economic Value of Equity (EVE) and the introduction of an SOT for Net Interest Income (NII).

Please note that we recently also published an article about the new disclosure requirements for IRRBB which is closely related to this topic.

Changes to the supervisory outlier test

Banks have been subject to an SOT already since the 2006 IRRBB Guidelines. The SOT is an important tool for supervisors to perform peer reviews and to compare IRRBB exposures between banks. The SOT measures how the EVE responds to an instantaneous parallel (up and down) yield curve shift of 200 basis points. Changes in EVE that exceed 20% of the institution’s own funds will trigger supervisory discussions and may lead to additional capital requirements.

Some changes to the SOT were included in the 2018 update of the IRRBB Guidelines. Next to further guidance on its calculation, the existing SOT was complemented with an additional SOT. The additional SOT was based on the same metric and guidelines, but the scenarios applied were the six standard interest rate scenarios introduced in the BCBS Standards. Also, a threshold of 15% compared to Tier 1 capital was applied. In the 2018 IRRBB Guidelines, the additional SOT was considered an ‘early warning signal’ only.

The new update of the IRRBB Guidelines includes two important SOT-related changes, which are incorporated through amendments to Article 98 (5) of the CRD: the replacement of the 20% SOT for EVE and the introduction of the SOT for NII. Both changes are discussed in more detail below.

Replacement of the 20% SOT for EVE

The first part of the amended Article 98 (5) concerns the replacement of the original 20% SOT by the 15% SOT. While many banks are probably already targeting levels below 15%, we expect that this change will limit the maneuvering capabilities of banks as they will likely choose to implement a management buffer. Note that not only the threshold is lower (15% instead of 20%), but also the denominator (Tier 1 capital instead of own funds). Furthermore, the worst outcome of all six supervisory scenarios should be used, as opposed to worst outcome of just the two parallel ones. Combined, this leads to a significant reduction in the EVE risk to which a bank may be exposed.

Some other noteworthy updates to the SOT for EVE that are not directly related to the CRD amendment are listed below:

• The post-shock interest floor decreases from -100 to -150 basis points and it increases to 0% over a 50-year instead of a 20-year period.
• In the calibration of the interest rate shocks for currencies for which the shocks have not been prescribed, the most recent 16-year period should be used (instead of the 2000-2015 period which is still underlying the shocks for the other currencies).
• When aggregating the results over currencies, some additional offsetting (80% as opposed to 50%) is granted in case of Exchange Rate Mechanism (ERM) II currencies with a formally agreed fluctuation band narrower than the standard band of +/-15%. Currently, only positions in the Denmark Krona (DKK) qualify for this treatment.

Introduction of the SOT for NII

The second part of the amended Article 98 (5) concerns the introduction of an entirely new SOT. It is aimed at measuring the potential decline in NII for two standard interest rate shock scenarios. Compared to the SOT for EVE, the SOT for NII requires many more modeling assumptions, in particular to determine the expected balance sheet development. The consultation paper provides clarity on the approach the EBA wants to take but two decisions are explicitly consulted.

The SOT for NII compares the NII for a baseline scenario with the NII in a shocked scenario over a one-year horizon. The two shocks that need to be applied are the two instantaneous parallel shocks that are also used in the SOT for EVE. Furthermore, the same requirements that are specified for the SOT for EVE apply, for example the use of the floor and the aggregation approach. The two exceptions are the requirements to use a constant balance sheet assumption (as opposed to a run-off balance sheet) and to include commercial margins and other spread components in the calculations. The commercial margins of new instruments should equal the prevailing levels (as opposed to historical ones).

The two decisions for which the EBA is seeking input are:

The scope/definition of NII
In its narrowest definition, the SOT will focus on the difference between interest income and interest expenses. The EBA, however, also considers using a broader definition where the effect of market value changes of instruments accounted for at Fair Value (∆FV) is added, and possibly also interest rate sensitive fees and commissions.

The definition of the SOT’s threshold
Article 98 (5) requires the EBA to specify what is considered a ‘large decline’ in NII, in which case the competent authorities are entitled to exercise their supervisory powers. This first requires a metric. The EBA is consulting two:

• The first metric is calculating the change in NII (the difference between the shocked and baseline NII) relative to the Tier 1 Capital:
• The second metric is calculating the change in NII relative to the baseline scenario, after correcting for administrative expenses that can be allocated to NII:
• where α is the historical share of NII relative to the operating income as reported based on FINREP input.

The pros of the narrow definition of NII are improved comparability and ease of computation, where the main pro of the broader definition is that it achieves a more comprehensive picture, which is also more in line with the EBA IRRBB Guidelines. With respect to the metrics, the first (capital-based) metric is the simplest and it is comparable to the approach taken for the SOT for EVE. The second metric is close to a P&L-based metric and the EBA argues that its main advantage is that “it takes into account both the business model and cost structure of a bank in the assessment of the continuity of the business operations”. It does involve, however, the application of some assumptions on determining the α parameter.

Thresholds for the four possible combinations

For each of the four possible combinations (definition of NII and specification of the metric), the EBA has determined, using data from the December 2020 Quantitative Impact Study (QIS), what the corresponding thresholds should be. Their starting point has been to make the SOT for NII as stringent as the SOT for EVE. Effectively, they reverse engineered the threshold to achieve a similar number of outliers under both measures. We expect that the proposed threshold for any of the four possible combinations will not be constraining for the majority of banks. The resulting proposed thresholds are included in the table below:

Table 1 – Comparison of the proposed thresholds for each combination of metric and scope

The impact of including Fair Value changes seems arbitrary as it increases the threshold for the capital-based metric and decreases the threshold for the P&L-based metric. Also, from a comparability and computational perspective, the narrow definition of NII may be preferred. Furthermore, the capital-based metric is less intuitive for NII than it is for EVE, and consequently, the P&L-based one may be preferred. It is also noted in the consultation paper that if the shocked NII after the correction for administrative expenses (the numerator) is negative, it will also be considered an outlier.

Conclusion

In the past years, many banks have invested heavily in their IRRBB framework following the 2018 update of the IRRBB Guidelines. Once again, an investment is required. Even though there are not many surprises in the proposed updates related to the SOTs, small and large banks alike will need to carefully assess how the changes to the existing SOT and the introduction of the new SOT will impact their interest rate risk management. Banks still have the opportunity to respond to all three consultation papers until 4 April 2022.
