CORES Scenario Analysis & Stress Testing 2 — Questions and Answers
Question 1: A bank's stress test reveals a 40% drop in net interest income under a severe rate shock scenario. Which management action is MOST appropriate as an immediate response?
- Increase loan originations to boost revenue
- Review asset-liability duration gaps and consider hedging strategies (Correct answer)
- Suspend dividend payments permanently
- Halt all new stress testing until conditions normalize
Correct answer: Review asset-liability duration gaps and consider hedging strategies
Duration mismatches drive net interest income sensitivity, so reviewing and hedging asset-liability gaps directly addresses the identified stress vulnerability.
Question 2: In reverse stress testing, what is the primary starting point for the analysis?
- A regulator-defined adverse macroeconomic scenario
- A predefined loss threshold or business failure outcome (Correct answer)
- The firm's historical worst-case loss event
- Current capital adequacy ratios
Correct answer: A predefined loss threshold or business failure outcome
Reverse stress testing works backward from a defined failure or threshold outcome to identify scenarios that could produce it.
Question 3: Which of the following BEST describes a 'plausibility filter' applied during scenario selection?
- A statistical test confirming scenarios fall within two standard deviations
- A review ensuring scenarios are severe yet conceivably possible given historical or emerging risks (Correct answer)
- A regulatory checklist of approved scenario types
- A model validation step that rejects outlier assumptions
Correct answer: A review ensuring scenarios are severe yet conceivably possible given historical or emerging risks
A plausibility filter ensures chosen scenarios are both sufficiently severe and credibly possible, not merely extreme statistical outliers.
Question 4: An operational risk team is designing a pandemic scenario. Which dimension is MOST critical to include beyond direct health impacts?
- Foreign exchange rate movements
- Staff unavailability and third-party service disruption (Correct answer)
- Credit spread widening on sovereign bonds
- Equity market volatility indices
Correct answer: Staff unavailability and third-party service disruption
Pandemic scenarios must capture workforce and supply chain disruption because operational risk materializes through process and people failures, not just market moves.
Question 5: When aggregating scenario losses across business lines, which challenge is MOST commonly encountered?
- Inability to convert qualitative assessments to dollar amounts
- Double-counting correlated losses that affect multiple units simultaneously (Correct answer)
- Lack of historical data for frequency distributions
- Regulatory prohibition on cross-unit aggregation
Correct answer: Double-counting correlated losses that affect multiple units simultaneously
Correlated scenarios can trigger losses in multiple business lines at once, making simple summation overstate total impact if dependencies are not modeled.
Question 6: A firm uses a 99.9th percentile VaR for operational risk capital. A scenario analysis produces a loss exceeding this figure. What is the BEST interpretation?
- The scenario is statistically impossible and should be discarded
- The scenario identifies a tail risk not fully captured by the VaR model (Correct answer)
- The VaR model must be recalibrated immediately to match the scenario
- Regulatory capital requirements are automatically breached
Correct answer: The scenario identifies a tail risk not fully captured by the VaR model
Scenario losses exceeding VaR thresholds highlight tail risks that statistical models may underestimate, which is exactly the value of scenario analysis.
Question 7: Which governance control BEST ensures scenario analysis outputs are used in decision-making rather than filed and ignored?
- Requiring all scenarios to be submitted to regulators quarterly
- Integrating scenario results into capital planning, risk appetite, and board reporting cycles (Correct answer)
- Mandating that scenario designers also perform model validation
- Publishing scenario assumptions publicly for transparency
Correct answer: Integrating scenario results into capital planning, risk appetite, and board reporting cycles
Embedding scenario results into capital planning and board reporting creates accountability and ensures findings drive actual risk management decisions.
