FRM Part II · FRM Exam Part II · Credit Value Adjustment
A bank has an interest rate swap in which it receives fixed from a counterparty. Assume the counterparty is the only defaultable party. How does the unilateral CVA on this trade compare with that on an otherwise identical trade with a longer maturity, all else equal?
The longer-maturity swap normally has higher unilateral CVA. Expected exposure builds as rates move, and a longer horizon accumulates more counterparty default probability. CVA therefore depends on exposure profile and default timing, not just notional, and zero initial value does not mean zero CVA.
- AIt is typically lower for the longer trade because exposure decays
- BIt is identical because CVA depends only on the notional amount
- CIt is typically higher for the longer trade because of greater potential exposure and longer default horizonCorrect
- DIt is zero for both because swaps have no exposure at inception
Explanation
For a swap, expected exposure usually grows with time due to rate diffusion before amortisation effects, and a longer horizon adds more cumulative default probability. Thus CVA generally rises with maturity. Notional alone does not determine CVA, and a zero-value start does not imply zero future exposure.
