Intelligent Basel III SA Compliance for Optimal Risk Weighting
CRR III fundamentally revises the credit risk standardised approach: more granular exposure classes, new risk weights from 0% to 1,250%, stricter due diligence obligations for ECAI ratings and differentiated treatment of real estate exposures by loan-to-value ratio.
The revised credit risk standardised approach (SA-CR) under CRR III increases risk sensitivity through differentiated exposure classes for sovereigns, institutions, corporates, retail and specialised lending. Risk weights range from 0% for top-rated sovereign bonds to 1,250% for high-risk positions. Real estate exposures receive new LTV-based risk weights – residential from 20%, commercial from 60%.
We offer a comprehensive portfolio of advanced solutions for the strategic implementation of all Basel III SA requirements. Our approach combines deep risk modelling expertise with effective technology solutions for sustainable compliance excellence and RWA optimisation.

Intelligent optimisation of the Basel III standardised approach is the key to sustainable RWA efficiency and regulatory excellence. Our SA solutions enable institutions not only to achieve regulatory compliance but also to develop strategic capital advantages through optimised risk weighting and predictive SA planning. By combining deep risk modelling expertise with advanced technologies, we create sustainable competitive advantages while protecting sensitive corporate data.
Optimal standardised approach implementation requires more than regulatory compliance. Our solutions create strategic RWA advantages and operational superiority in SA management.
7 QUESTIONS, BRIEFLY ANSWERED
The credit risk standardised approach (SA-CR) is the regulatory method for calculating risk-weighted assets (RWA) for credit risk without internal models. Exposures are classified into categories (sovereigns, institutions, corporates, retail, real estate and specialised lending) and assigned supervisory risk weights from 0% to 1,250% based on the borrower's creditworthiness and exposure type.
CRR III introduces more granular exposure classes, revises risk weights for real estate exposures (LTV-based), strengthens due diligence obligations when using external ratings (ECAI) and introduces the output floor at 72.5%, fully effective from 2030. Specialised lending and subordinated exposures also receive more differentiated treatment.
Risk weight assignment is based on the exposure class and external credit assessment (ECAI rating). Sovereign exposures receive 0% to 150%, institution exposures 20% to 150%, corporate exposures 20% to 150% (unrated: 100%). Residential real estate is weighted by loan-to-value (LTV), from 20% at LTV up to 50%, up to 70% at LTV above 100%. Commercial real estate starts at 60%.
ECAI stands for External Credit Assessment Institution, external rating agencies such as Moody's, S&P or Fitch. Banks may use their ratings for risk weight assignment but must conduct their own due diligence assessments under Article 122a CRR. This means banks must independently evaluate borrower creditworthiness and cannot rely solely on external ratings.
The output floor limits capital relief from internal models (IRB): RWA from internal models must not fall below 72.5% of RWA calculated under the standardised approach. Phase-in runs from 50% (2025) to 72.5% (2030). For pure SA-CR banks this has no direct impact, but the standardised approach becomes the reference benchmark for all institutions.
CRR III introduces LTV-based risk weighting for real estate exposures. Residential properties receive risk weights from 20% (LTV up to 50%) to 70% (LTV above 100%). Commercial properties start at 60% (LTV up to 55%) and increase to 150%. The distinction between whole-loan approach and loan-splitting approach allows flexible capital treatment.
ADVISORI provides end-to-end SA-CR implementation under CRR III: exposure classification and mapping to regulatory categories, risk weight assignment and RWA calculation, integration of ECAI ratings with due diligence processes, credit risk mitigation technique (CRM) adjustments, regulatory reporting migration (COREP) and preparation for supervisory examinations. We have completed over 20 regulatory projects across the DACH region.
