基于信用风险迁移条件风险价值最小化的贷款组合优化模型
Loan's Portfolio Optimization Model of CvaR Minimum Based on Credit Risk Transfer
摘要
Abstract
Introducing credit risk transfer to calculate loan yield and introducing Conditional Value at Risk to measure loan's portfolio risk, the loan's portfolio optimization model of CvaR minimum based on credit risk transfer is set up.The contribution of the model is firstly that the CVaR of consistency risk calculation parameter is used instead of VaR, so the extremity loss of loan's portfolio is controlled.Secondly, the influence of credit risk transfer on the return rate standard deviation is reflected in the model, and the real risk of loan is reflected more impersonally, thus the problem to only calculate individual loan's yield whereas neglecting the credit transfer in the current topic is solved. Tirdly, through law constrain, we control the liquidity risk to avoid the liquidity hazard of asset allocation to guarantee the allocation legal and operational.关键词
