Abstract
Instances of massive losses in derivative markets in the 2008 financial crisis urged Basel Committee to introduce the policy of Basel III in 2011, which is also called CCR (Counterparty Credit Risk). As we know, the loss caused by the downgraded counterparty credit rating accounts more than that of default of contracts in CCR, which means the result gets higher in the calculation of the CVA (Credit Value Adjustment). For the banks, it’s a big issue to find an open and high-powered CVA solution. Under the framework of the Basel III, this paper will introduce the CVA on the OTC (over the counter) derivative for the banks. Except for the basic requirements of the Basel, this paper tries to put more attention on the calculation of the CVA and the mitigation. As a whole, there are two key points in this paper. Firstly, with the consideration of the effects of exposure on hazard rate, this paper will establish a model which has commingled the WWR(Wrong Way Risk) to calculate CVA; Secondly, this paper will introduce some risk mitigation methods. The Monte Carlo method (or Monte Carlo experiments) is the main numerical method to solve the mathematical problems in this paper.
