Abstract
It is common for financial Institutes to use OTC financial derivative contracts to hedge their risk, which will be influenced by the default of counterparty. To reduce the loss caused by the counterparty credit risk, both two trading parties should take into account the probability of counterparty default in the beginning of contract making process. Meanwhile, the default probability of counterparty will raise when then counterparty is facing potential loss, which is called Wrong Way Risk. In this paper, the author will use reduced form model to model the probability of counterparty default, which is assumed to be affected by the contract value, and calculate the unilateral credit value adjustment under different circumstances, discussing the influence of wrong way risk to the contract value of financial derivatives.
