FRM Part I · FRM Exam Part I · Modeling Non-Parallel Term Structure Shifts and Hedging
A risk manager hedges a bond portfolio with a single futures position sized so that its DV01 equals the portfolio's DV01. Which statement best describes the protection this hedge provides?
A single DV01-matched hedge protects against small parallel yield curve shifts only. If the curve steepens, flattens or twists, the portfolio and hedge have exposures at different maturities, so a residual gain or loss remains. Multi-factor hedging needs additional instruments to match key-rate exposures.
- AIt protects against parallel shifts in the yield curve, but a change in slope or curvature can still leave a residual gain or lossCorrect
- BIt protects against level, slope and curvature changes simultaneously, because DV01 captures every factor
- CIt protects only against changes in credit spreads, because DV01 is a spread measure
- DIt protects against non-parallel shifts but not against parallel shifts
Explanation
A DV01 match neutralizes the first-order price effect of a small parallel shift. Because the two positions can have exposures concentrated at different maturities, a steepening or twist produces different gains and losses on each. Hedging several factors requires at least one instrument per factor, such as key-rate exposures.
