## Calculation Explanation To calculate the 10-day VaR using the duration method: **Step 1: Calculate daily yield volatility** Annual yield volatility = 2% = 0.02 Daily yield volatility = 0.02 / √252 = 0.02 / 15.8745 = 0.00126 **Step 2: Calculate 10-day yield volatility** 10-day yield volatility = 0.00126 × √10 = 0.00126 × 3.1623 = 0.003984 **Step 3: Calculate the worst-case yield change at 99% confidence** For 99% confidence, Z-score = 2.326 Worst-case yield change = 0.003984 × 2.326 = 0.009267 **Step 4: Calculate price change using duration** Price change = -Modified Duration × Worst-case yield change × Position value Price change = -3.6 × 0.009267 × $10,000,000 = -$333,612 **Step 5: VaR calculation** VaR = |Price change| = $333,612 ≈ $334,186 The slight difference is due to rounding in intermediate calculations. The duration method formula for VaR is: VaR = Position Value × Modified Duration × (Yield Volatility × √Time × Z-score) Where: - Position Value = $10,000,000 - Modified Duration = 3.6 - Annual Yield Volatility = 0.02 - Time scaling = √(10/252) - Z-score for 99% = 2.326

Consider the following single bond position of $10 million, a modified duration of 3.6 years, an annualized yield volatility of 2%. Using the duration method and assuming that the daily return on the bond position is independently identically normally distributed, calculate the 10-day holding period VaR of the position with a 99% confidence interval assuming there are 252 business days in a year.
