Fed asks for capital-rule comments
Federal regulators have requested comment on three proposals to modernize the regulatory capital framework for banks — a signal that capital metrics and stress scenarios are likely to evolve and will need to be baked into risk models and counterparty assessments. Quant teams should expect new calibration requirements and reporting fields if these proposals advance. (federalreserve.gov)
The package names the Basel III (expanded risk‑based) proposal for Category I/II firms, a revised Standardized Approach for credit exposures, and a separate G‑SIB surcharge proposal, with the agencies setting a June 18, 2026 comment deadline. (federalreserve.gov (federalreserve.gov)) Under the expanded risk‑based approach, Category I and II banking organizations would report a single set of risk‑based capital ratios that incorporate credit risk, operational risk, market risk and CVA rather than maintaining two parallel calculations. (federalreserve.gov (federalreserve.gov)) The market‑risk framework would be mandatory for any banking organization with more than $5 billion of trading activity or trading activity equal to or above 10% of total assets, a threshold that shifts which institutions must run hybrid market‑risk capital models. (federalreserve.gov (federalreserve.gov)) The Standardized Approach revisions would introduce more granular mortgage risk weights using loan‑to‑value bands, recalibrate retail and corporate risk weights, and change exposure measures for counterparty credit risk and securitizations. (fdic.gov (fdic.gov)) Category III and IV firms would be required to include most components of accumulated other comprehensive income (AOCI) in regulatory capital with a five‑year transition, and the proposal would remove the regulatory capital deduction for mortgage servicing assets. (fdic.gov (fdic.gov)) The Fed’s G‑SIB surcharge NPR specifically targets measurement of systemic risk and would change the methodology for calculating the additional surcharge that applies to the largest, most complex bank holding companies. (mayerbrown.com (mayerbrown.com)) Press and agency impact estimates show the largest, globally active banks would see modest net reductions in required common‑equity Tier 1 capital (Reuters reporting cited an aggregate ~4.8% CET1 decline for Wall Street banks), while the agencies state system capital would remain well above pre‑2008 levels. (money.usnews.com (money.usnews.com)) (federalreserve.gov (federalreserve.gov)) Quant and risk teams face concrete calibration tasks: the proposals trigger hybrid market‑risk modeling for firms above the $5 billion/10% trading threshold and set a proposed $1 trillion notional derivative exposure trigger for CVA capital, implying updates to market‑risk/CVA modules, risk‑weight mappings and regulatory reporting fields if finalized.
