文本描述
我国金融市场作为一个发展中的新兴市场,市场风险必将随着金融市场的发展而逐 渐加大,市场风险的增加对风险管理提出了新要求。国际上广泛接受和采用的风险管理 标准,是上个世纪 90 年代以后发展起来的新型风险管理工具--VaR。本文研究的内容是 在我国金融市场管理中应用 VaR 方法的可行性。本文首先把 VaR 方法与传统金融市场 风险管理方法进行了比较,其次介绍了 VaR 模型体系及模型检验方法,接下来阐述 了我国金融市场风险管理引入 VaR 方法的必要性,VaR 方法在我国运用的过程中存在的 问题及相应对策。最后通过对我国证券市场的股票指数的实证分析,验证 VaR 方法对我 国金融市场风险管理的适用性。 关键词:金融市场风险,VaR,可行性 ABSTRACT China’s money market is a development emerging market. With the development of money market the market risk will enlarge gradually. The increase of market risk set the new request to the risk management. Value at Risk (VaR) technique is a new risk management method that has been developed in 1990’s. It has become the standard measure of market risk employed by financial institutions and their regulators. This article studies the Feasibility of VaR in China’s Money Market Risk Management. This article first compared the VaR method with the tradition money market risk management method, next introduced the VaR model system and the model inspection procedure, then researched the necessity of introducing the VaR method to our country money market risk management, the question and the corresponding countermeasure which existed in the utilization of the VaR method, finally confirmed the serviceability of the VaR method in our country money market risk management by the analysis of our country stock index.
