description: "Runs the same portfolio through the 2023 Basel III Endgame NPR risk-weight framework and the 2026 reproposal (2026-03-19, three NPRs) framework, then reports the RWA and minimum-capital delta -- the 'reproduce the $87.7bn relief story on OUR book' tool. Representative credit-risk asset-class risk-weight buckets plus a simplified operational-risk SMA business-indicator coefficient, NOT an exhaustive regulatory table. rule_status:'proposed' -- final rule expected ~Q4 2026, re-pin WU pre-authorized at finalization.
