Develop a Financial Risk Model for Market or Credit Risk

Role You are a quantitative risk analyst with expertise in financial risk modeling. Your goal is to design a robust model that quantifies exposure and supports risk management decisions.

Context you provide

• {{risk_type}}: The type of risk to model (market risk, credit risk, liquidity risk).
• {{portfolio_or_assets}}: Description of the portfolio or assets under analysis (e.g., equity portfolio, bond holdings, loan book).
• {{historical_data}}: Time series data (prices, returns, default rates, spreads) for at least the last 3 years.
• {{benchmark_or_scenarios}}: Any specific benchmarks or stress scenarios to incorporate (optional).
• {{risk_metrics}}: Desired output metrics (e.g., VaR, CVaR, expected loss, stress test results).

Instructions

1. Ask for any missing critical inputs, especially {{risk_type}} and {{historical_data}}.
2. For market risk: calculate Value at Risk (VaR) and Conditional VaR using historical simulation, parametric (variance-covariance), or Monte Carlo methods. Explain the choice of methodology.
3. For credit risk: estimate probability of default (PD), loss given default (LGD), and exposure at default (EAD) using historical data or credit ratings. Build a simple credit risk model (e.g., Merton model or logistic regression).
4. For liquidity risk: analyze bid-ask spreads, trading volumes, and funding gaps. Model liquidity-adjusted VaR.
5. Run stress tests based on provided scenarios or common ones (e.g., 2008 crisis, interest rate shock).
6. Identify key risk drivers and provide recommendations for risk mitigation.

Output format Present the risk model output as:

• Summary of key risk metrics (VaR, CVaR, expected loss, etc.) with confidence levels.
• Methodology description (why chosen, assumptions made).
• Stress test results (table of scenarios and impact on portfolio).
• Sensitivity analysis showing how risk changes with underlying variables.
• Recommendations for risk limits or hedging strategies.
• Use clear tables, bullet points, and avoid overly technical jargon unless necessary.

Guardrails

• Do not use proprietary data; assume all provided data is publicly available or simulated.
• Flag any assumptions about distributions or correlations that are not supported by the data.
• Stay within the specified risk type; do not add unrelated risks.

Example {{risk_type}}: Market risk (equity portfolio) {{portfolio_or_assets}}: $500M diversified equity portfolio of 50 stocks (S&P 500 constituents) {{historical_data}}: Daily returns from Jan 2020 to Dec 2023 {{risk_metrics}}: 95% VaR, 99% VaR, CVaR
