Capital Requirements Regulation

Introduction and Overview

The Capital Requirements Regulation (CRR), officially Regulation (EU) No 575/2013, is a cornerstone of the European Union's banking regulatory framework. It establishes a single set of harmonised prudential rules that credit institutions and investment firms throughout the EU must respect. The CRR aims to strengthen the resilience of the EU's banking sector by ensuring institutions have sufficient capital, liquidity, and robust risk management processes to absorb potential losses and withstand financial shocks.

This regulation is directly applicable in all EU Member States, ensuring a uniform application of prudential standards and creating a level playing field for financial institutions operating within the single market.

Evolution and Relation to Other Laws

The CRR is part of the Capital Requirements Directive IV (CRD IV) package, which also includes the Capital Requirements Directive (Directive 2013/36/EU). Together, they transpose the Basel III international regulatory framework for banks into EU law.

• Capital Requirements Directive (CRD - 2013/36/EU): While the CRR sets out the detailed prudential requirements (the 'single rulebook'), the CRD governs access to deposit-taking activities and sets out supervisory rules, including capital buffers, corporate governance, and remuneration policies.
• Bank Recovery and Resolution Directive (BRRD - 2014/59/EU): The CRR defines own funds and introduces the concept of 'eligible liabilities', which are crucial for the bail-in tool under the BRRD, ensuring that failing banks can be resolved without resorting to taxpayer money.
• Amendments (CRR II / CRR III): The CRR has been significantly amended over time to keep pace with international standards and address evolving risks. Key amendments include:
  • Regulation (EU) 2019/876 (CRR II): Introduced the Net Stable Funding Ratio (NSFR), a binding leverage ratio, and requirements for Total Loss-Absorbing Capacity (TLAC) for global systemically important institutions (G-SIIs).
  • Regulation (EU) 2024/1623 (part of the 'Banking Package 2021' or 'CRR III'): Finalises the implementation of the Basel III framework, introducing an 'output floor' to limit the capital benefit from internal models, enhancing rules for credit risk, market risk, and operational risk, and incorporating ESG risk considerations.

Main Goals and Objectives

The primary goal of the CRR is to enhance the financial stability of the EU by strengthening the prudential soundness of credit institutions and investment firms. Its key objectives are:

• Increase Capital Levels and Quality: To ensure banks hold more and higher-quality capital (Common Equity Tier 1) to absorb losses.
• Improve Risk Management: To establish robust and uniform rules for managing credit risk, market risk, operational risk, and counterparty credit risk.
• Enhance Liquidity Standards: To introduce harmonised liquidity requirements, including the Liquidity Coverage Ratio (LCR) and the Net Stable Funding Ratio (NSFR).
• Limit Excessive Leverage: To introduce a simple, non-risk-based backstop measure, the leverage ratio, to constrain the build-up of excessive leverage.
• Mitigate Concentration Risk: To set strict limits on large exposures to a single client or group of connected clients.
• Create a Single Rulebook: To ensure consistent application of prudential rules across the EU, fostering a level playing field and a more integrated banking market.

Who It Applies To

The CRR applies to:

• Credit Institutions: As defined in the regulation, primarily banks that take deposits and grant credits.
• Investment Firms: Certain investment firms, particularly larger ones that pose systemic risks similar to credit institutions.
• Financial Holding Companies and Mixed Financial Holding Companies: These parent undertakings are required to comply with the rules on a consolidated basis.

Key Dates and Timeline

• Adopted: 26 June 2013
• Published in Official Journal: 27 June 2013
• Entered into Force: 28 June 2013
• Date of Application: 1 January 2014 (with various transitional provisions for different requirements).
• Last Updated: The provided text is a consolidated version that includes amendments up to Regulation (EU) 2025/1215, published on 25 June 2025.

Exemptions

The CRR includes several specific exemptions and derogations, including:

• Individual Application: Competent authorities may waive the application of certain prudential requirements (e.g., capital, large exposures) on an individual basis for subsidiary institutions if they are included in the consolidated supervision of a parent undertaking in the same Member State (Article 7).
• Liquidity Requirements: Competent authorities may waive the application of liquidity requirements on an individual basis for institutions that are part of a single liquidity sub-group (Article 8).
• Intragroup Exposures: Exposures to parent undertakings, subsidiaries, or other related entities may be exempted from capital requirements or large exposure limits under specific conditions (Article 113(6), Article 400(1)(f)).
• Small Trading Book Business: Institutions with a very small trading book business may be exempt from calculating market risk capital requirements for it, treating those positions under the credit risk framework instead (Article 94).

Key Provisions and Requirements

Own Funds and Eligible Liabilities (Part Two)

This part defines the components of regulatory capital, structured into tiers:

• Common Equity Tier 1 (CET1) Capital: The highest quality of capital, comprising common shares, retained earnings, and other reserves that can fully absorb losses on a going-concern basis.
• Additional Tier 1 (AT1) Capital: Instruments that can absorb losses on a going-concern basis but are of lower quality than CET1 (e.g., perpetual subordinated bonds with loss-absorption features).
• Tier 2 (T2) Capital: Instruments that can absorb losses in a gone-concern scenario (i.e., in insolvency), such as subordinated debt with a minimum original maturity of five years.
• Eligible Liabilities: Defines liabilities that can be written down or converted to equity in a resolution scenario to absorb losses and recapitalise a failing institution (relevant for TLAC/MREL).

Capital Requirements (Part Three)

This part sets out the calculation of risk-weighted exposure amounts (RWEA) for Pillar 1 risks:

• Credit Risk: Institutions can use the Standardised Approach (applying risk weights prescribed in the regulation) or, with supervisory approval, the Internal Ratings-Based (IRB) Approach (using their own internal models to estimate risk parameters like PD and LGD).
• Operational Risk: The risk of loss from inadequate internal processes, people, systems, or external events. The CRR III amendment introduces a single standardised approach for all banks.
• Market Risk: The risk of losses in on- and off-balance-sheet positions arising from movements in market prices. The framework includes a simplified standardised approach, an alternative standardised approach, and an alternative internal model approach.
• CVA Risk: Own funds requirements for the risk of losses arising from changes in the credit valuation adjustment of OTC derivatives.

Large Exposures (Part Four)

• Definition: An exposure to a client or group of connected clients is a 'large exposure' if its value is 10% or more of the institution's Tier 1 capital.
• Limit: An institution must not incur an exposure to a client or group of connected clients that exceeds 25% of its Tier 1 capital.
• Interbank Limit: For exposures to other institutions or G-SIIs, stricter limits apply.

Liquidity (Part Six)

• Liquidity Coverage Ratio (LCR): Requires institutions to hold a buffer of high-quality liquid assets (HQLA) sufficient to cover their net cash outflows over a 30-day stress period.
• Net Stable Funding Ratio (NSFR): Requires institutions to maintain a stable funding profile in relation to their on- and off-balance-sheet activities over a one-year horizon.

Leverage (Part Seven)

• Leverage Ratio: A non-risk-based backstop measure, calculated as Tier 1 capital divided by a measure of total exposure (including on- and off-balance-sheet items). The minimum requirement is 3%.

Affected Products, Actors, and Processes

• Affected Actors: Credit institutions, investment firms, financial holding companies, mixed financial holding companies, and their management bodies. Also affects supervisors and resolution authorities.
• Affected Products/Services: All banking products, including loans (corporate, retail, mortgages), derivatives, securities financing transactions, securitisation positions, and off-balance-sheet commitments.
• Affected Processes: Risk management, internal capital adequacy assessment (ICAAP), credit approval, collateral management, regulatory reporting, and public disclosure.

Penalties and Enforcement

Penalties for non-compliance are not detailed within the CRR itself. Enforcement is the responsibility of the national competent authorities (and the ECB for significant institutions within the Banking Union). Supervisory powers, including the ability to impose administrative penalties and other supervisory measures, are primarily laid down in the Capital Requirements Directive (CRD).
