What is Value at Risk (VaR) and how is it calculated?
Value at Risk (VaR) is a central metric in market risk assessment:
🎯 Definition and Concept
•
Maximum expected loss over a defined time horizon at a given confidence level
•
Typical parameters: 99% or 99.9% confidence level, 1-day or 10-day horizon
•
Interpretation: "With 99% probability, the loss in the next X days will not be greater than Y euros"
•
Aggregation capability: Enables summarization of various risk positions
📊 Calculation Methods
•
Historical Simulation - Using historical returns to estimate the loss distribution - Sorting historical scenarios by losses - Determining VaR as the corresponding quantile (e.g., 99% quantile) - Advantages: No distribution assumptions, simple implementation
•
Parametric Method (Variance-Covariance Approach) - Assumption of normally distributed returns - Calculation using formula: VaR = μ + σ · z_α - Where μ = expected value, σ = standard deviation, z_α = z-value for confidence level - Advantages: Computational efficiency, easy scaling across different time horizons
•
Monte Carlo Simulation - Generating thousands of random scenarios based on statistical properties - Valuing the portfolio under each scenario - Determining VaR as the corresponding quantile of the simulated distribution - Advantages: Flexibility with complex instruments, consideration of non-linear effects
⚙ ️ Practical Aspects
•
Square root of time rule: Scaling 1-day VaR to longer horizons (VaR_T = VaR_
1 · √T)
•
Backtesting: Comparison of VaR forecasts with actual losses
•
Limitation: Integration into limit systems as upper bound for risk exposure
•
Supplementation: Combination with stress tests to cover extreme events
