FRM Part II · FRM Exam Part II · Counterparty Risk and Beyond
A bank has a swap with a counterparty. Its expected positive exposure profile is flat at USD 10 million, the counterparty's expected negative exposure (the bank's liability) is flat at USD 6 million, and the lifetime discounted effect is such that the counterparty default probability is 4%, the bank's own default probability is 2%, LGD is 50% for both, and defaults are independent. Using the simple bilateral approximation (ignoring first-to-default and discounting), what is the bilateral CVA (net CVA minus DVA)?
Net bilateral CVA is unilateral CVA minus DVA. CVA is 10 times 4% times 50%, equal to USD 0.20 million. DVA is 6 times 2% times 50%, equal to USD 0.06 million. The net charge is USD 0.14 million; adding DVA instead would wrongly give USD 0.26 million.
- AUSD 0.14 millionCorrect
- BUSD 0.20 million
- CUSD 0.08 million
- DUSD 0.26 million
Explanation
CVA = 10 x 4% x 50% = 0.20. DVA = 6 x 2% x 50% = 0.06. Net adjustment = 0.20 - 0.06 = 0.14. Using the CVA alone gives 0.20, and adding DVA gives 0.26, which is a sign error.
