An illustrative read on Day-1 CRR3 RWA uplift across European G-SIB portfolios — broken down by asset class, portfolio type and jurisdiction. Public sources: EBA Basel III monitoring reports, EBA CRR3 quantitative impact note, and the subset of European G-SIBs that have disclosed a CRR3 first-time-adoption RWA bridge in their FY2025 Pillar 3 or results press releases. Methodology at the foot of the page.
The EBA’s most recent Basel III monitoring report anchors the industry at roughly low double-digit pre-management-action RWA uplift. Individual G-SIB FY2025 disclosures sit materially above that anchor where the bank’s book is skewed to IRB corporate / unrated-SA / mortgage exposures. Methodology and sources at the foot of this page.
Anonymised European G-SIB. How the post-management-action number moved, the three levers that carried the weight, and the supervisory conversation that signed it off. Specific basis-point and euro outcomes withheld at client request.
CFO Capital-Impact Case · coming soon Publishing shortly — currently under review.Day-1 RWA uplift on a constant-book basis. Illustrative ranges. Estimation method — the high end of each range is anchored to the highest Day-1 uplift disclosed by a European G-SIB for that asset class in its FY2025 Pillar 3 or results press release; the low end to the median of the EBA Basel III monitoring exercise; and the “observed skew” column notes where Ezelman mandate experience clusters within that range.
| Asset class | Illustrative Day-1 range | EBA benchmark anchor | Ezelman mandate skew |
|---|---|---|---|
| Residential mortgages | +15% to +25% | ~+12% | Upper half |
| Large corporates (IRB) | +10% to +20% | ~+9.5% | Upper half |
| Specialised lending | +10% to +18% | ~+8% | Upper half |
| SME corporates | +8% to +14% | ~+7.5% | Mid-range |
| Unrated corporates (SA) | +20% to +30% | ~+14.5% | Upper half |
| Banks & FIs | +6% to +12% | ~+6.5% | Mid-range |
| Counterparty credit risk (SA-CCR) | +8% to +16% | ~+8% | Mid-range |
| Operational risk (BIC) | +3% to +6% | ~+3% | Mid-range |
| Output-floor bite (all-book) | +4% to +8% | ~+4.5% | Mid-range |
The CRR3 Impact Index is an illustrative reference built from three public-data streams, triangulated with Ezelman mandate observations to position where within each range a given portfolio is likely to land.
Sources. (i) The EBA Basel III monitoring exercise ↗ — aggregate RWA impact estimates for European banks; (ii) the FY2025 Pillar 3 reports and results press releases of the European G-SIB cohort that have published a CRR3 first-time-adoption RWA bridge (BNP Paribas, Deutsche Bank, Santander, UniCredit, Intesa Sanpaolo and peers); (iii) the EBA’s Impact analysis of the CRR3 prudential framework / final-package QIS notes, and Regulation (EU) 2024/1623 as the authoritative legal text. Every figure on this page is either (a) drawn from one of those sources, (b) an estimate with the method stated above, or (c) labelled as a mandate-skew observation.
What we do not do. We do not publish specific basis-point or euro outcomes from individual Ezelman client mandates. Those figures are withheld at client request, consistent with our sitewide public-data policy (every figure on ezelman.com is public-sourced, an estimate with stated methodology, or qualitative).
Deeper asset-class and jurisdiction analysis — with the EBA/Pillar 3 bridges walked at a single-bank level — is released to Ezelman Intelligence subscribers.
