Guides and frameworks that use this term

GuideModel Risk ValidationModel risk validation is the independent testing of a specific model's conceptual soundness, ongoing performance, and outcomes, performed by staff or a third-party firm genuinely separate from that model's development. It is the 'effective challenge' function required under SR 26-2 and SR 11-7, distinct from broader model risk management program design.GuideModel Risk Management SoftwareModel risk management software centralizes a bank's model inventory, tracks validation status and lifecycle events, and automates governance workflows like tiering, revalidation scheduling, and audit-trail documentation. It replaces manual spreadsheet tracking, which becomes unmanageable once an institution has more than a handful of tiered models.FrameworkSR 26-2SR 26-2, issued jointly by the Federal Reserve, OCC, and FDIC on April 17, 2026, is the current US interagency guidance on model risk management. It supersedes SR 11-7 (2011) and SR 21-8 (2021), preserving core disciplines like effective challenge and independent validation while shifting to a risk-based approach tailored to an institution's model risk profile, size, and complexity.FrameworkOSFI E-23OSFI E-23 is Canada's enterprise-wide model risk management guideline for federally regulated financial institutions. The final 2025 guideline takes effect on 1 May 2027 and applies a risk-based approach across model identification, inventory, risk ratings, lifecycle governance, independent review, monitoring, third-party models, and decommissioning.
