Use this guide to see the chapter as one story: financial innovation increased model use; crises exposed model risk; regulation evolved; SR 11-7 (SR 26-2) became the organizing framework for modern MRM.
Focus on the lesson learned from each event, not on memorizing dates.
Guidance existed around specific model types, capital models, validation, and supervisory review, but MRM was not yet organized as one coherent enterprise framework.
SR 11-7 (SR 26-2) organizes model risk around the full lifecycle: development, implementation, use, validation, monitoring, governance, documentation, issues, and oversight.
All three seek safer model use and stronger governance, but they emphasize different dimensions of control.
| Dimension | United States | United Kingdom | European Union |
|---|---|---|---|
| Core framework | SR 11-7 (SR 26-2) / OCC 2011-12 | PRA SS1/23 | ECB EGIM / TRIM, EBA, CRR / CRD |
| Scope | Broad model universe | Broad enterprise MRM for large firms | Strongest focus on regulatory capital models |
| Signature strength | Lifecycle governance + independent validation | Board accountability + model risk appetite | Technical scrutiny + model approval |
| Regulatory style | Principles + supervisory guidance | Principles-based supervisory expectations | Prescriptive technical review |
| Student memory aid | Enterprise framework | Top-down ownership | Technical rigor |
Model risk moved beyond a technical validation issue and became part of institutional risk governance and board oversight.
Development/business ownership, independent risk challenge, and internal audit gained distinct responsibilities and escalation paths.
Conceptual soundness, monitoring, outcomes analysis, benchmarking, limitations, and effective challenge became standard expectations.
Models are controlled from development through use, monitoring, change, remediation, and retirement.
Institutions need a centralized inventory, ownership, validation status, materiality, and risk-based prioritization.
The chapter treats the US framework as a global benchmark whose ideas are echoed in UK and EU practice.
What failed? Assumptions about normal markets, liquidity, and feedback effects.
MRM lesson: stress testing, assumption testing, tail risk.
What failed? Overreliance on leveraged strategies and weak model-risk governance.
MRM lesson: user understanding, governance, limits.
What failed? Sophisticated models used with extreme leverage under stressed market conditions.
MRM lesson: independent validation, stress testing, model misuse.
What failed? Correlation, tail, housing, and diversification assumptions.
MRM lesson: conceptual soundness, data, validation, systemic model risk.
Divide the class into four groups. Give each group one case: Black Monday, Orange County, LTCM, or Subprime CDOs. Ask:
You are the board risk committee of a global bank. Your US, UK, and EU regulators examine the same model.
Which regulator is most likely to focus on enterprise governance, board accountability, or technical model approval?
Because greater model use increased both benefits and exposure to model errors, misuse, common assumptions, and correlated failures. Repeated crises made the risk visible.
Because the model can be used outside its intended purpose, under conditions where assumptions fail, or with poor governance, data, implementation, or controls.
Because it organizes MRM as an end-to-end enterprise discipline rather than a narrow model-validation exercise.
