ERBA / Standardized RWA Calculator (Basel Endgame 2026)

Credit-risk expanded risk-based approach (ERBA) / standardized-approach RWA calculator per the 2026 Basel Endgame reproposal (BCBS/US NPR, reproposed 2026-03-19, comments closed 2026-06-18, final expected ~Q4 2026). Runs an exposure book -- residential real estate by LTV band, retail (QRRE transactor/revolver, other retail), corporate (ECRA external-rating or SCRA unrated), SME support factor, off-balance-sheet CCFs -- through a chosen rule_set (2023 original NPR or 2026 reproposal) and returns per-exposure risk weights, aggregate RWA, and a receipt. rule_status stays proposed until the rule finalizes. Feeds compare_basel_2023_vs_2026 for the versus-2023 capital delta.
