CRD Systemic Risk Buffer

The Systemic Risk Buffer (SyRB) is a macroprudential capital instrument established under Art. 133 of the Capital Requirements Directive (CRD). It addresses long-term, non-cyclical systemic risks that could cause serious disruptions to the financial system or the real economy. The buffer rate ranges from 1–3% of risk-weighted exposure amounts in 0.5 percentage point increments, and may reach up to 5% under specific conditions. Only Common Equity Tier 1 (CET 1) capital qualifies. Each EU member state transposes the SyRB into national law – in Germany through Section 10e of the German Banking Act (KWG), with the BaFin as the competent authority. The buffer rate must be reviewed at least every two years.

The CRD establishes three distinct buffers for systemic risks: The G-SIB buffer applies to globally systemically important institutions identified using the EBA methodology based on five criteria – size, cross-border activity, interconnectedness, substitutability and complexity. The buffer rate ranges from 1–3.5%. The O-SII buffer (Other Systemically Important Institutions) targets domestically significant institutions with a buffer rate of up to 3%. The general systemic risk buffer (SyRB) has a broader scope and can apply to all institutions or specific exposure classes to address macroprudential risks not captured by the countercyclical or SII buffers.

The combined buffer requirement (CBR) is the sum of all CRD capital buffers that an institution must hold on top of the minimum capital requirements under CRR Art. 92. It comprises: the capital conservation buffer (CCoB, 2.5%), the countercyclical capital buffer (CCyB, currently 0.75% in Germany), the G-SIB or O-SII buffer, and the systemic risk buffer (SyRB). If an institution falls below the CBR, automatic distribution restrictions apply: the institution must calculate the Maximum Distributable Amount (MDA) and is restricted from paying dividends, variable remuneration and AT1 coupon payments.

Since CRD V (2019), the systemic risk buffer can be applied sectorally, i.e. to specific exposure classes rather than the entire loan book. In Germany, BaFin imposed a 2% sectoral systemic risk buffer for residential real estate lending in 2022. This was reduced to 1% in April 2025 (effective May 2025) as residential property risk indicators improved. The sectoral SyRB targets risk positions where mortgages on domestic residential property reduce own funds requirements. EBA guidelines define the appropriate subsets of sectoral exposures to which the SyRB may be applied.

CRD VI introduces significant changes to the systemic risk buffer framework: First, climate and environmental risks can explicitly be addressed through the SyRB. Second, EBA guidelines for sectoral exposure classes are expanded to ensure more consistent application across the EU. Third, notification obligations to EBA and ESRB are strengthened for buffer changes exceeding 3%. Fourth, the interaction between the SyRB and SII buffers is clarified, particularly regarding overlaps between the sectoral SyRB and O-SII buffer.

ADVISORI supports institutions throughout the full implementation of CRD capital buffer requirements. We conduct gap analyses of existing buffer calculations and capital planning, review the systemic importance designation (G-SIB/O-SII) and assess the impact on the combined buffer requirement. Our consultants assist with integrating the systemic risk buffer into ICAAP capital planning, building automated monitoring systems for buffer thresholds and preparing for CRD VI requirements. We also support regulatory communication with supervisory authorities and audit documentation.

A breach of the combined buffer requirement (CBR), which includes the systemic risk buffer, triggers automatic distribution restrictions. The institution must calculate the Maximum Distributable Amount (MDA) and faces limitations on dividends, variable remuneration and AT1 coupon payments. A capital conservation plan must be submitted to the competent authority. Persistent breaches may lead to additional supervisory measures, up to and including restrictions on business activities. Proactive monitoring with an adequate buffer above minimum requirements is therefore essential from both a regulatory and business perspective.
