Summary of EBA/GL/2018/04 – Guidelines on Internal Stress Testing

Core Content and Main Objectives

The document, EBA/GL/2018/04, outlines guidelines for internal stress testing by financial institutions within the European Union. It aims to establish common organizational requirements, methodologies, and processes for conducting stress tests, with a focus on capital adequacy and risk management. These guidelines are aligned with the European Banking Authority (EBA) and the European Union's regulatory framework, particularly Regulation (EU) No 1093/2010 and Directive 2013/36/EU.

The main objective is to ensure that financial institutions perform stress tests in a consistent, transparent, and effective manner, supporting risk management practices and strategic decision-making. The guidelines also address the integration of stress testing into the broader risk management framework, including the Internal Capital Adequacy Assessment Process (ICAAP) and the Internal Liquidity Adequacy Assessment Process (ILAAP).

Key Requirements and Procedures

Compliance and Reporting Obligations

• Financial institutions must inform the EBA whether they comply with or intend to comply with these guidelines by a specified date.
• If no compliance statement is received, the EBA will assume non-compliance.
• Compliance statements must be submitted via a specific form and sent to compliance@eba.europa.eu, along with the reference "EBA/GL/201x/xx".
• These statements will be published on the EBA website in accordance with Article 16(3) of Regulation (EU) No 1093/2010.

Scope and Applicability

• These guidelines apply to national competent authorities and financial institutions subject to the provisions of Article 4(2)(i) of Regulation (EU) No 1093/2010 and Article 4(1) of the same regulation.
• They also apply to institutions participating in specific stress tests, in line with the scope and level of application defined in Articles 108 and 109 of Directive 2013/36/EU.

Definitions and Taxonomy

• The document defines several key terms related to stress testing:
  • Stress test of solvency: Evaluation of the impact of a specific scenario on the institution's capital position and ability to absorb losses.
  • Stress test of liquidity: Assessment of the impact of a scenario on the institution's liquidity position.
  • Bottom-up stress test: Based on internal models and data, focusing on specific portfolios or the institution as a whole.
  • Top-down stress test: Conducted by competent authorities, using general or systemic scenarios.
  • Stress test scenario: A set of risk factors that reflect the characteristics of a stress event.
  • Reversal stress test: Starts with a predefined outcome and identifies scenarios that could lead to it.
  • Scenario severity: The degree of impact of a scenario, ranging from basic to adverse.
  • Scenario probability: The likelihood of a scenario occurring, based on coherence with current macroeconomic and financial conditions.
  • Data aggregation infrastructure: The systems and processes used to collect, process, and report risk data.
  • Risk sensitivity analysis: Evaluation of the impact of specific risk factors on capital and liquidity.

Implementation and Operational Aspects

Implementation of Stress Testing Programs

• Institutions must establish a stress testing program that includes:
  • Types of stress tests and their objectives.
  • Frequency of different stress tests.
  • Internal risk management mechanisms and responsibilities.
  • Coverage of relevant risk factors and portfolios.
  • Methodological details and model assumptions.
  • Appropriate documentation and regular review.

Roles and Responsibilities

• The risk management committee must approve the stress testing program and oversee its implementation.
• The board of directors and senior management must ensure the program is effectively executed and monitored.
• The program must be integrated into the institution's overall risk management framework and be subject to regular evaluation and updates.

Data Infrastructure

• Institutions must ensure that their data infrastructure supports the stress testing program, including:
  • Integration of large volumes of data.
  • Flexibility and quality control of data.
  • Automation of data aggregation to minimize errors.
  • Ensuring data completeness and accuracy across all levels of the institution.

Scope and Coverage

• Stress tests should cover all material risk types, including market, credit, and operational risks.
• They must be conducted at both the individual entity and group levels, considering the interdependencies and correlations between different risk factors.
• Institutions with international operations must also consider regional and sector-specific risk factors.

Proportionality

• The stress testing program must be proportionate to the institution's size, complexity, and risk profile.
• Larger and more complex institutions are expected to have more comprehensive programs, while smaller and less complex ones may have simpler approaches.

Conclusion

These guidelines provide a comprehensive framework for conducting internal stress tests, ensuring consistency, transparency, and effectiveness. They emphasize the importance of data quality, scenario analysis, and the integration of stress testing into the overall risk management process. Institutions are required to maintain and regularly update their stress testing programs, ensuring they align with regulatory requirements and support strategic decision-making.
