Answer: The bank's model calculates interest rate risk based on the median duration of the bonds in the portfolio.
**B is correct.** In the case of bad luck, no penalty is given, as would be the case for a bank affected by unpredictable movements in rates or markets. However, when risk models are not precise enough, a penalty is typically given since model accuracy could have easily been improved. **Explanation:** - **Option A** represents market movements that are unpredictable and would be considered "bad luck" rather than model inadequacy - **Option B** describes a modeling deficiency where using median duration instead of proper duration measures indicates the model is not precise enough, which could be improved - **Option C** represents an unpredictable market crisis, which would be considered bad luck - **Option D** represents a natural disaster (force majeure), which is clearly outside the model's scope The Basel framework distinguishes between exceptions due to bad luck (market movements) and exceptions due to model inadequacy. When models can be easily improved but aren't, penalties are applied.
