Answer: Assessing potential changes in dependencies between different measurable and immeasurable risks faced by the bank
**Correct Answer: A** **Explanation:** **A is correct.** Macroeconomic stress testing is a holistic approach that aims to stress both measurable and immeasurable risks and the dependencies between them. This comprehensive assessment of risk interdependencies makes it particularly suitable for evaluating how different types of risks interact under stressed economic conditions. **B is incorrect.** Reverse stress testing is more suitable for stress testing operational resilience, since the event of an intolerable disruption can be used as the predefined outcome and scenarios can then be identified that could result in this outcome. **C is incorrect.** This is an example of a parameter stress testing approach, which uses a statistical change in a parameter (the interest rate) to assess the impact on a modeled output. **D is incorrect.** This describes reverse stress testing, which begins with the outcome (insolvency) and assesses potential scenarios to result in that outcome. **Key Learning Points:** - **Macroeconomic stress testing**: Holistic approach assessing dependencies between measurable and immeasurable risks - **Parameter stress testing**: Focuses on statistical changes in specific parameters - **Reverse stress testing**: Starts with predefined adverse outcomes and works backward to identify scenarios
