What is Op Risk?
The risk of loss from inadequate or failed internal processes, people, and systems or from external events
Historically, a residual risk category i.e. not market or credit = operational
New focus & importance, thanks to Basel II and market changes

Basic Thesis
Bad – maybe worst of all alternatives Require capital cushion, but use internal
models
Limited effectiveness Banks w/ highest op risk levels are least
likely to credibly assess
![Page 4: The Return of The Rogue](https://reader035.vdocuments.us/reader035/viewer/2022070503/568161d7550346895dd1dd66/html5/thumbnails/4.jpg)
Basic Thesis
High costs: Definition, modeling, and data problems Enforcement likely to be lacking Room for interest groups –lawyers,
accountants, risk management experts – to capture definition and management
Incentive to “manage the model,” rather than op risk

Alternatives
Status quo Plausible deniability re: other limits
Do it better Future:
incentivize market-based solutions (e.g. insurance)
Non-financial metrics Other proposals – compensation
revisions
