FRM Part I · FRM Exam Part I · Modeling Non-Parallel Term Structure Shifts and Hedging
A bond portfolio has key rate '01s (the dollar change in value for a one basis point fall in each key rate) of USD 120 at the 2-year, USD 300 at the 5-year, and USD 580 at the 10-year key rates. The portfolio's DV01 for a parallel one basis point shift is closest to:
The portfolio DV01 is USD 1,000. A parallel shift moves all key rates equally, so the total price sensitivity equals the sum of the individual key rate '01s: 120 plus 300 plus 580. Using only the largest exposure would understate the total interest rate risk.
- AUSD 1,000Correct
- BUSD 580
- CUSD 300
- DUSD 120
Explanation
For a parallel shift, every key rate moves by the same amount, so the portfolio DV01 is the sum of the key rate '01s: 120 + 300 + 580 = USD 1,000. Choosing 580 uses only the largest exposure and ignores the other key rates.
