摘要 宏观压力测试,作为压力测试方法在宏观经济分析中的具体运用,可以提供极端事件对金融体系影响的前瞻性信息。随着各国金融监管当局对系统性风险的日趋重视,宏观压力测试方法逐渐成为检验一国银行体系的脆弱性、维护金融稳定的首选工具。本文主要研究宏观压力测试在银行信用风险评估中的应用,并在已有的模型成果的对比分析基础上,建立适用于我国的宏观压力测试模型并以此进行实证分析。本文以贷款违约率作为评估银行系统信用风险的指标,选取对银行信贷违约风险构成冲击的宏观经济变量,通过多元线性回归模型将其整合成为一个综合性指标。研究结果发现:名义国内生产总值(NGDP)和通货膨胀率指标(CPI)对银行体系的贷款表现冲击力较强。在此基础上构建了两种宏观经济极端情境,在关于NGDP大幅下降和CPI骤升的压力情境设定下,银行体系的贷款违约率都出现了不同程度的大幅度提高。尤其在关于通货膨胀率的情境设定下,贷款违约率的增幅高于其在NGDP下降情境下的增幅。 This paper focuses on the application of macro-testing in the assessment of banking credit risk.We establish a model specifically designed for China situations and define overdue loan ratio as credit risk indicator.The results show that macroeconomic variables especially NGDP and CPI have much stronger impact on banking loan system than other factors.Then we construct two extreme macro economic scenarios.Banking default probability increases sharply with the scenarios of sharp decline in NGDP and surge in CPI.The increase in loan default probability with CPI scenario is bigger than that with NGDP scenario.
