Find out moreExplore how Basel IV reforms and enhanced due diligence requirements will transform regulatory capital assessments for credit risk, fostering a more resilient and informed financial sector.
The Basel IV reforms, which are set to be implemented on 1 January 2025 via amendments to the EU Capital Requirement Regulation, have introduced changes to the Standardized Approach for credit risk (SA-CR). The Basel framework is implemented in the European Union mainly through the Capital Requirements Regulation (CRR3) and Capital Requirements Directive (CRD6). The CRR3 changes are designed to address shortcomings in the existing prudential standards, by among other items, introducing a framework with greater risk sensitivity and reducing the reliance on external ratings. Action by banks is required to remain compliant with the CRR. Overall, the share of RWEA derived through an external credit rating in the EU-27 remains limited, representing less than 10% of the total RWEA under the SA with the CRR.
The Basel Committee on Banking Supervision (BCBS) identified the excessive dependence on external credit ratings as a flaw within the Standardised Approach (SA), observing that firms frequently used these ratings to compute Risk-Weighted Assets (RWAs) without adequately understanding the associated risks of their exposures. To address this issue, regulators have implemented changes aimed to reduce the mechanical reliance on external credit ratings and to encourage firms to use external credit ratings in a more informed manner. The objective is to diminish the chances of underestimating financial risks in order to further build a more resilient financial industry. Overall, the share of Risk Weighted Assets (RWA) derived through an external credit rating remains limited, and in Europe it represents less than 10% of the total RWA under the SA.
The concept of due diligence is pivotal in the regulatory framework. It refers to the rigorous process financial institutions are expected to undertake to understand and assess the risks associated with their exposures fully. Regulators promote due diligence to ensure that banks do not solely rely on external assessments, such as credit ratings, but instead conduct their own comprehensive analysis.
The due diligence is a process performed by banks with the aim of understanding the risk profile and characteristics of their counterparties at origination and thereafter on a regular basis (at least annually). This includes assessing the appropriateness of risk weights, especially when using external ratings. The level of due diligence should match the size and complexity of the bank's activities. Banks must evaluate the operating and financial performance of counterparties, using internal credit analysis or third-party analytics as necessary, and regularly access counterparty information. Climate-related financial risks should also be considered, and due diligence must be conducted both at the solo entity level and consolidated level.
Banks must establish effective internal policies, processes, systems, and controls to ensure correct risk weight assignment to counterparties. They should be able to prove to supervisors that their due diligence is appropriate. Supervisors are responsible for reviewing these analyses and taking action if due diligence is not properly performed.
Banks should have methodologies to assess credit risk for individual borrowers and at the portfolio level, considering both rated and unrated exposures. They must ensure that risk weights under the Standardised Approach reflect the inherent risk. If a bank identifies that an exposure, especially an unrated one, has higher inherent risk than implied by its assigned risk weight, it should factor this higher risk into its overall capital adequacy evaluation.
Banks need to ensure they have an adequate understanding of their counterparties’ risk profiles and characteristics. The diligent monitoring of counterparties is applicable to all exposures under the SA. Banks would need to take reasonable and adequate steps to assess the operating and financial condition of each counterparty.
The external credit assessment institutions (ECAIs) are credit rating agencies recognised by National supervisors. The External Credit ECAIs play a significant role in the SA through the mapping of each of their credit assessments to the corresponding risk weights. Supervisors will be responsible for assigning an eligible ECAI’s credit risk assessments to the risk weights available under the SA. The mapping of credit assessments should reflect the long-term default rate.
Exposures to banks, exposures to securities firms and other financial institutions and exposures to corporates will be risk-weighted based on the following hierarchy External Credit Risk Assessment Approach (ECRA) and the Standardised Credit Risk Assessment Approach (SCRA).
ECRA: Used in jurisdictions allowing external ratings. If an external rating is from an unrecognized or non-nominated ECAI, the exposure is considered unrated. Also, banks must perform due diligence to ensure ratings reflect counterparty creditworthiness and assign higher risk weights if due diligence reveals greater risk than the rating suggests.
SCRA: Used where external ratings are not allowed. Applies to all bank exposures in these jurisdictions and unrated exposures in jurisdictions allowing external ratings. Banks classify exposures into three grades:
The CRR Final Agreement includes a new article (Article 495e) that allows competent authorities to permit institutions to use an ECAI credit assessment assuming implicit government support until December 31, 2029, despite the provisions of Article 138, point (g).
In cases where external credit ratings are used for risk-weighting purposes, due diligence should be used to assess whether the risk weight applied is appropriate and prudent.
If the due diligence assessment suggests an exposure has higher risk characteristics than implied by the risk weight assigned to the relevant Credit Quality Step (CQS) of an exposure, the bank would assign the risk weight at least one higher than the CQS indicated by the counterparty’s external credit rating.
Criticisms to this approach are:
The regulation requires the bank to conduct due diligence to ensure a comprehensive understanding, both at origination and on a regular basis (at least annually), of the risk profile and characteristics of their counterparties. The challenges associated with implementing this regulation can be grouped into three primary categories: governance, business processes, and systems & data.
Governance
The existing governance framework must be enhanced to reflect the new responsibilities imposed by the regulation. This involves integrating the due diligence requirements into the overall governance structure, ensuring that accountability and oversight mechanisms are clearly defined. Additionally, it is crucial to establish clear lines of communication and decision-making processes to manage the new regulatory obligations effectively.
Business Process
A new business process for conducting due diligence must be designed and implemented, tailored to the size and complexity of the exposures. This process should address gaps in existing internal thresholds, controls, and policies. It is essential to establish comprehensive procedures that cover the identification, assessment, and monitoring of counterparties' risk profiles. This includes setting clear criteria for due diligence, defining roles and responsibilities, and ensuring that all relevant staff are adequately trained.
Systems & Data
The implementation of the regulation requires access to accurate and comprehensive data necessary for the rating system. Challenges may arise from missing or unavailable data, which are critical for assessing counterparties' risk profiles. Furthermore, reliance on manual solutions may not be feasible given the complexity and volume of data required. Therefore, it is imperative to develop robust data management systems that can capture, store, and analyse the necessary information efficiently. This may involve investing in new technology and infrastructure to automate data collection and analysis processes, ensuring data integrity and consistency.
Overall, addressing these implementation challenges requires a coordinated effort across the organization, with a focus on enhancing governance frameworks, developing comprehensive business processes, and investing in advanced systems and data management solutions.
