Executive introduction
The final Basel III reforms are becoming part of day-to-day balance-sheet economics for European banks. CRR3 and CRD6 began applying from 1 January 2025 for most elements, while the EU implementation of the revised market-risk framework has been deferred. The practical effect is broader than a regulatory recalculation: capital requirements increasingly influence product pricing, portfolio allocation and the relative economics of internal-model and standardised exposures.
The output floor is central to this transition. It limits the extent to which modelled risk-weighted assets can fall below a percentage of standardised RWA. As the floor phases toward its fully loaded level, banks that are not constrained today can become constrained later even without deterioration in underlying credit quality.
Key takeaways
- The output floor makes standardised RWA strategically relevant even for internal-model banks.
- Capital planning should distinguish current transitional effects from fully loaded CRR3 economics.
- Operational-risk capital is more standardised, but internal operational-risk measurement remains essential.
- Pricing should reflect regulatory capital, economic capital, expected loss, liquidity and funding costs.
- Internal models remain valuable when they improve decisions even if their direct capital benefit declines.
The economics of the output floor
At a simplified level, final RWA equals the greater of internally modelled RWA and the applicable output-floor percentage multiplied by standardised RWA. A portfolio can therefore become more capital intensive as the floor phases in even if borrower quality, expected loss and internal risk estimates remain unchanged.
This creates a forward-looking management problem. New business written under transitional capital needs to be assessed against the fully loaded capital regime to avoid future deterioration in risk-adjusted returns.
Credit risk and portfolio strategy
Banks should separate expected loss, economic capital and regulatory capital. A transaction may have low expected loss but unattractive regulatory capital, while a low regulatory requirement does not prove low tail risk. CRR3 can therefore change product economics without changing the underlying economic uncertainty.
Portfolio steering should examine which sectors, collateral structures and exposure classes become relatively more or less capital efficient under the revised standardised approach and the output floor.
Operational risk after CRR3
The revised framework uses a more standardised approach to operational-risk capital. This increases comparability but should not displace internal scenario analysis, cyber risk, fraud assessment, business-continuity testing and operational-resilience measurement.
Regulatory operational-risk capital answers a minimum-capital question. It does not identify which technology, fraud or third-party scenario is most likely to disrupt a particular bank.
Internal models still matter
Internal models remain useful for pricing, risk selection, limit setting, provisioning, stress testing, ICAAP and portfolio management. Their strategic value should be assessed by decision usefulness rather than merely by the amount of regulatory capital they save.
The output floor may therefore encourage a healthier distinction between models used for risk insight and models justified mainly by regulatory capital optimisation.
Technical framework
A simplified RAROC measure is (Revenue - Expected Loss - Operating Cost - Funding Cost) / Capital. Under CRR3, the denominator can increase because of regulatory methodology even when the risk of the customer has not changed. Pricing systems should therefore show both current and fully loaded capital consumption and reconcile regulatory with economic capital.
Practical example
If an internal-model portfolio generates EUR 6 billion of RWA while its standardised RWA is EUR 10 billion, a 50% floor is non-binding at EUR 5 billion. At a 72.5% floor, the floor becomes EUR 7.25 billion and therefore binding. The portfolio consumes EUR 1.25 billion more regulatory RWA without a change in underlying borrower quality.
What risk leaders should do now
- Maintain current and fully loaded CRR3 capital forecasts.
- Reprice portfolios where the output floor materially changes marginal capital consumption.
- Keep economic-risk measurement distinct from regulatory optimisation.
- Review internal-model strategy by portfolio and decision usefulness.
- Ensure operational-risk governance remains risk sensitive despite standardised capital.
- Explain RWA changes to boards through clear attribution to business growth, risk movement and methodology.
Frequently asked questions
Does the output floor eliminate internal models?
No. It constrains regulatory capital benefits but internal models remain valuable for risk differentiation, pricing, stress testing and portfolio management.
Why should banks model fully loaded capital now?
Because business originated under transitional rules can become less attractive as the floor phases in.
Is regulatory capital the same as economic risk?
No. Regulatory capital reflects prudential rules; economic risk is an internal assessment of loss uncertainty and should remain independently measured.
Conclusion
CRR3 changes the relationship between risk measurement and balance-sheet economics. The appropriate response is not mechanical RWA minimisation but disciplined comparison of regulatory capital, economic capital and sustainable commercial value.
Banks that integrate the fully loaded framework into pricing and portfolio strategy can manage the transition proactively rather than discovering capital inefficiency only when the floor becomes binding.
