Our Competencies
Choose the area that fits your requirements
The Advanced IRB Approach (A-IRB) allows institutions to estimate all risk parameters internally — probability of default (PD), loss given default (LGD), exposure at default (EAD) and credit conversion factors (CCF) — using proprietary models. ADVISORI guides you from model development through supervisory approval to ongoing validation — for risk-sensitive capital management under CRR III.
The CRD combined buffer requirement defines how capital conservation buffer, countercyclical buffer, systemic risk buffer and G-SII/O-SII buffers interact under a single framework. ADVISORI advises financial institutions on buffer stacking rules, capital distribution restrictions, MDA calculation and capital conservation planning — ensuring full compliance with the CRD buffer framework.
Capital adequacy requirements under the CRD comprise the overall capital requirement from Pillar 1 minimum, SREP capital add-on (P2R), combined buffer requirement, and Pillar 2 Guidance (P2G). We support banks in supervisory capital quantification, preparation for CRD VI changes, and integration of ESG risks into the capital adequacy assessment.
The CRD Capital Conservation Buffer under Art. 129 CRD V/VI requires EU credit institutions to hold 2.5% Common Equity Tier 1 (CET1) capital above minimum requirements. When breached, the MDA (Maximum Distributable Amount) calculation triggers automatic distribution restrictions on dividends, bonuses, and AT1 coupons. ADVISORI advises on strategic buffer management, CRD VI implementation, and regulatory capital planning across the EU framework.
The countercyclical capital buffer under Art. 130 CRD (Directive 2013/36/EU) requires credit institutions to maintain an institution-specific buffer as the weighted average of applicable national CCyB rates. The calculation under Art. 140 CRD considers the geographic distribution of credit risk exposures. ADVISORI supports you with CRD-compliant buffer calculation, ESRB reciprocity requirements and implementation of CRD VI changes effective January 2026.
End-to-end consulting for implementing the CRD credit risk framework: from the reformed Standardised Approach (SA-CR) and Output Floor calculations to ECAI due diligence requirements. We support your institution in the compliant implementation of CRR III capital requirements and the strategic optimisation of your risk weighting.
The Capital Requirements Directive (CRD) is the core EU directive governing banking supervision, governance, and authorization of credit institutions. From CRD IV through CRD V to the current CRD VI, it defines the supervisory framework that each EU member state must transpose into national law. ADVISORI has been supporting banks and financial institutions with CRD implementation for over 14 years.
Fit and Proper ensures that members of the management body, supervisory board and key function holders meet regulatory requirements for knowledge, experience, integrity and time commitment. With CRD VI expanding the scope to key function holders and the revised EBA/ESMA joint guidelines introducing AML/CFT competence requirements, banks face growing complexity in their suitability assessment processes. ADVISORI supports you with systematic implementation of all Fit and Proper requirements across the EU framework.
The CRD defines binding requirements for the internal governance of credit institutions – from the three lines of defence model through internal control systems to the independent compliance function. With the new EBA guidelines (EBA/CP/2025/20) and CRD VI, requirements for risk management governance, control functions, and organizational structures are tightening significantly. ADVISORI supports you with gap analysis, implementation, and ongoing monitoring of your internal governance framework aligned with EBA standards.
Directive 2013/36/EU (CRD IV) together with the CRR forms the regulatory foundation of EU banking supervision under Basel III. We support financial institutions in the full implementation of governance, SREP and Pillar 2 requirements — from gap analysis to supervisory-compliant implementation.
The use of internal models to calculate risk-weighted assets requires supervisory approval from the ECB and national authorities. We guide your institution through the entire IRB approval process — from model development and validation per the revised ECB guide 2025 to successful regulatory approval. With our expertise, you navigate the tightened CRD VI requirements, the output floor and internal model restrictions with confidence.
The CRD establishes binding liquidity requirements for EU banks — from the Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR) to internal liquidity risk management. ADVISORI supports financial institutions with regulatory implementation, liquidity governance and building robust stress testing frameworks.
The Liquidity Coverage Ratio (LCR) requires credit institutions to hold sufficient high-quality liquid assets (HQLA) to cover net cash outflows over a 30-day stress scenario. The minimum ratio is 100%. Under the EU implementation of Basel III through CRR/CRD, Delegated Regulation 2015/61 governs HQLA categories, inflow/outflow rates, and reporting requirements. ADVISORI supports banks with compliant LCR calculation, HQLA optimization, and supervisory reporting.
Professional consulting for the implementation and optimization of market risk management systems in accordance with the requirements of the Capital Requirements Directive (CRD). We support you in meeting regulatory requirements and making strategic use of market risk information.
CRD Net Stable Funding Ratio defines a structural liquidity metric to promote stable funding structures and reduce liquidity transformation risks in EU financial institutions. As a leading consulting firm, we develop tailored RegTech solutions for intelligent Available Stable Funding optimization, automated Required Stable Funding calculation, and predictive NSFR management with full IP protection.
Identify, assess, and manage operational risks under CRR Art. 312§324 and CRD systematically. We guide your institution through selecting the right measurement approach — from the basic indicator approach and standardised approach to the SMA transition under Basel III — and implement OpRisk frameworks with loss databases, RCSA processes, and KRI systems.
CRD outsourcing establishes the strategic foundation for modern banking outsourcing management and defines comprehensive third-party risk management systems, service provider monitoring, and outsourcing procedures for financial institutions. As a leading consulting firm, we develop tailored RegTech solutions for intelligent outsourcing orchestration, automated outsourcing management systems, and predictive third-party excellence with full IP protection.
CRD Passporting establishes the strategic foundation for modern EU Banking Passport operations and defines comprehensive cross-border services, branch systems and international regulatory coordination for financial institutions. As a leading consulting firm, we develop tailored RegTech solutions for intelligent passporting orchestration, automated cross-border compliance systems and predictive EU banking excellence with full IP protection.
CRD Pillar 2 defines supervisory review procedures and internal capital adequacy assessments for EU financial institutions. As a leading consulting firm, we develop tailored RegTech solutions for ICAAP automation, SREP optimisation and intelligent supervisory dialogue with full IP protection.
CRD Pillar 3 defines comprehensive disclosure requirements and transparency obligations for EU financial institutions to strengthen market discipline. As a leading consulting firm, we develop tailored RegTech solutions for automated disclosure processes, intelligent transparency management, and fully automated compliance monitoring with complete IP protection.
Frequently Asked Questions about CRD Pillar 1
What does CRR Pillar 1 regulate and what capital ratios must banks maintain?
Pillar 1 of the Capital Requirements Regulation (CRR, EU Regulation 575/2013) sets the quantitative minimum capital requirements for credit institutions in the EU. Banks must maintain three capital ratios relative to their risk-weighted assets (RWA) at all times:
Common Equity Tier 1 (CET1) ratio: at least 4.5% of RWA
Tier 1 capital ratio: at least 6% of RWA
Total capital ratio: at least 8% of RWA
In addition, capital buffers apply: the capital conservation buffer (2.5%), the countercyclical capital buffer (0–2.5%, set by national authorities), and systemic buffers for globally and domestically systemically important institutions. In practice, large European banks typically maintain CET1 ratios of 10–13%. ADVISORI supports credit institutions in monitoring and optimising these ratios on an ongoing basis.
How are risk-weighted assets (RWA) for credit risk calculated under the CRR?
The CRR provides two approaches for calculating credit risk RWA:
1. Standardised Approach (SA, Art. 111–141 CRR): Each exposure is assigned to an exposure class (sovereigns, institutions, corporates, retail, etc.) and receives a regulatory risk weight from 0% to 150%. RWA equals the exposure amount multiplied by the risk weight.
2. Internal Ratings-Based Approach (IRB, Art. 142–191 CRR): Banks use their own risk models to estimate probability of default (PD), loss given default (LGD), exposure at default (EAD), and effective maturity (M). Under Foundation IRB, the supervisor prescribes LGD and EAD; under Advanced IRB, the bank estimates all parameters itself.
CRR III also introduces the output floor: IRB-based RWA may not fall below 72.5% of standardised approach RWA, limiting excessive model benefits. ADVISORI supports institutions in methodology selection and implementation of both approaches.
What changes does CRR III bring to market risk capital requirements (FRTB)?
The Fundamental Review of the Trading Book (FRTB) fundamentally overhauls market risk capital requirements. Key changes under CRR III:
New boundary between trading and banking book with stricter reclassification rules
Standardised Approach (SA-TB): Sensitivity-based approach covering delta, vega, and curvature risks, replacing previous simplified methods
Internal Model Approach (IMA): Value-at-Risk replaced by Expected Shortfall (ES), supplemented by Default Risk Charge and Residual Risk Add-on
Desk-level approval: Each trading desk must pass PnL attribution tests and backtesting to use the IMA
The EU implementation timeline for FRTB includes transitional arrangements through 2027. ADVISORI supports banks in choosing between SA-TB and IMA and in implementing the required data infrastructure and risk models.
How do banks calculate the capital requirement for operational risk under CRR III?
CRR III introduces the Standardised Measurement Approach (SMA) as the sole approach for operational risk, replacing all previous methods (Basic Indicator, Standardised, and AMA approaches).
The SMA calculates the capital requirement in two steps:
1. Business Indicator Component (BIC): Based on the Business Indicator (BI), a metric derived from interest income, fee income, and trading income. Marginal coefficients of 12%, 15%, or 18% apply depending on the BI level.
2. Internal Loss Multiplier (ILM): Links the BIC to actual operational losses over the past 10 years. Institutions with above-average losses face a surcharge, while those with lower losses receive relief.
For large institutions (BI > EUR 1 billion), the use of historical loss data is mandatory. ADVISORI supports SMA implementation from loss data preparation through BIC calculation to model validation.
What is the output floor and how does it affect capital ratios?
The output floor is one of the most significant innovations of CRR III. It stipulates that RWA from internal models (IRB, IMA) may not fall below a certain percentage of standardised approach RWA.
The phase-in schedule is:
2025: 50% of standardised approach RWA 2026: 55%
2027: 60%
2028: 65%
2029: 70%
2030: 72.5% (final level)
Institutions that have previously calculated significantly lower RWA through internal models will experience material capital increases. According to EBA estimates, this primarily affects large banks with extensive IRB portfolios, whose RWA may rise by 10–20%.
ADVISORI’s output floor simulation shows institutions the impact on CET1, Tier 1, and total capital ratios early, supporting strategic capital planning.
What role does the leverage ratio play in CRR Pillar 1?
The leverage ratio is a non-risk-based metric that serves as a backstop to risk-weighted capital requirements. It is regulated under Art. 429–429g CRR.
The minimum requirement is:
3% Tier 1 capital relative to the total exposure measure
For global systemically important institutions (G-SIIs): an additional leverage ratio buffer of 50% of the G-SII buffer
The total exposure measure comprises on-balance-sheet assets, derivative exposures (under SA-CCR), securities financing transactions, and off-balance-sheet items. Unlike RWA-based ratios, there is no risk weighting – every exposure enters at its full nominal amount.
ADVISORI advises institutions on leverage ratio calculation, total exposure measure optimisation, and minimum ratio compliance.
How do Pillar 1 (CRR) and Pillar 2 (SREP) interact for capital requirements?
Pillar 1 and Pillar 2 complement each other in determining a bank’s total capital requirement:
Pillar 1 (CRR Art. 92): Quantitative minimum requirements – uniform for all institutions: 4.5% CET1, 6% Tier 1, 8% total capital relative to RWA.
Pillar 2 (CRD Art. 97–107): The supervisor sets institution-specific additional requirements through the SREP (Supervisory Review and Evaluation Process):
Pillar 2 Requirement (P2R): Binding additional requirement, typically 1–3% CET1Pillar 2 Guidance (P2G): Supervisory expectation, not legally binding but effectively required
The total requirement equals: Pillar 1 + capital buffers + P2R + P2G. For a typical large European bank, this means:
CET1 minimum: 4.5% + 2.5% (buffer) + 1.5% (P2R) + 1% (P2G) = approximately 9.5%
ADVISORI supports institutions with both Pillar 1 compliance and preparation for the SREP dialogue with supervisors.
