19 - Pricing and Mitigation of Counterparty Credit Exposures



Abstract We analyze the market price of counterparty risk and develop an arbitrage-free pricing valuation framework, inclusive of collateral mitigation. We show that the adjustment is given by the sum of option payoff terms, depending on the netted exposure, i.e. the difference between the on-default exposure and the predefault collateral account. We specialize our analysis to Interest Rates Swaps (IRS) and Credit Default Swaps (CDS) as underlying portfolio, and perform a numerical study to illustrate the impact of default correlation, collateral margining frequency, and collateral re-hypothecation on the resulting adjustment. We also discuss problems of current research interest in the counterparty risk community.

Basel II defines the counterparty credit risk as the amount that a financial institution would lose in the event that one of its counterparties defaults before the final settlement of the transaction. Unlike a firm's exposure to credit risk through a loan, where the exposure to credit risk is unilateral and only the lending bank faces the risk of loss, the counterparty credit risk creates a bilateral risk of loss, when both parties are default sensitive. Such risk is embedded in all financial contracts which are traded over the counter, where the credit quality of counterparties plays a key role.
