金融机构面临信用风险、市场风险和操作风险等诸多风险组成的整合风险。本文利用Copula方法对整合风险度量进行研究。以12家中国上市商业银行为研究对象,首先确定其信用风险、市场风险这两种风险收益率的分布,然后利用Copula构建相依结构模型,最后用蒙特卡罗模拟算法计算不同风险组合的VaR和CVaR,并利用返回测试检验模型的有效性。
金融機構麵臨信用風險、市場風險和操作風險等諸多風險組成的整閤風險。本文利用Copula方法對整閤風險度量進行研究。以12傢中國上市商業銀行為研究對象,首先確定其信用風險、市場風險這兩種風險收益率的分佈,然後利用Copula構建相依結構模型,最後用矇特卡囉模擬算法計算不同風險組閤的VaR和CVaR,併利用返迴測試檢驗模型的有效性。

At present,the financial institutions have to face the integrated risks such as the credit risk, market risk and operational risk. In this paper, the author takes 12 Chinese listed commercial banks as the research object. Firstly, the distribution of return rate of each risk is determined, and then the dependence structure is constructed by using Copula. Then the VaR and CVaR of different risk combination is calculate by using the Monte Carlo simulation method; finally the results calculated by Monte Carlo is proven efficient by back tests.
