为描绘商业银行大型集团客户在压力情景下的信用风险情况,本文以某银行过去12年的不良贷款数据为对象,进行了压力测试实证研究。在研究中引入还原不良贷款率作为中间变量,使用Logit回归建立宏观经济数据和还原不良贷款率之间的量化模型,进而通过商业银行内部评级数据调整得到不同情景下每个集团成员的违约概率;在此基础上,通过蒙特卡洛模拟计算损失分布情况,并估算集团关联风险所致额外损失额。研究结果显示,大型集团客户的压力损失分布,呈现明显的\"厚尾\"特征,进出口、质押式回购利率、工业生产者出厂价格指数、广义货币、工业增加值对其的影响较大。据此,本文建议监管部门应引导商业银行加强宏观经济和政策研究,扶优控劣优化用信结构,控制用信集中度。 相似文献

基于现金流的蒙特卡洛模拟方法,提出了一个制造业企业信贷风险压力测试的分析方法和框架。通过财务指标的计算,经营活动净现金流可以通过存货、应收账款、应付账款、产品价格、产品销量、生产成本以及周转率等会计科目进行表示,而企业经营活动净现金流是否为负可以作为判定制造业企业违约的标准。然后,在情景假设和随机变量估计的基础上,可以通过蒙特卡洛模拟计算违约概率。同时,利用企业的经营和财务数据进行了模拟测试。在金融机构的风险管理应用中,可以根据测试企业的具体情况对变量进行合理的设定,进而将研究提出的分析框架应用到不同的企业。 相似文献

信用评级中的违约率、违约概率研究 总被引:2,自引:0,他引:2
信用评级是对个人、经济体与金融工具履行各种经济承诺的能力及可信任程度的综合评价,本文通过对KMV评级模型的研究,指出在信用评级中的关键指标——“违约率和违约概率”在评级中的重要意义。 相似文献

压力测试是银行加强信用风险管理和监管部门实施宏观审慎监管的有用工具,但是压力测试模型的科学性制约了我国提高压力测试的水平。本文把传统的Logistic模型扩展为包含宏观冲击因子的MF-Logistic模型,将其用于信用风险压力测试。实证结果显示:基于MF-Logistic模型的信用风险压力测试能科学地度量宏观冲击因子和微观风险因素对信用风险的影响,并且能直观地显示银行在不同压力情景下的资本充足水平,对于商业银行和银行监管机构都具有较高的实用价值。 相似文献

2008年国际金融危机后,压力测试逐步成为量化评估金融体系系统性风险、推进宏观审慎管理的重要手段。本文以银行体系的不良贷款率为风险测度指标,运用Logistic模型,分别模拟2008年历史情景和历史最差情景来测算宏观经济因素波动对银行体系的冲击大小。从设置的两种情景压力测试结果看,消费和投资增速变化形成信用风险因子时,湖南省银行体系形成的不良贷款率都低于初期不良贷款率,湖南省银行体系稳定性较高。 相似文献

Based on the Black and Scholes (Black, F., and M. Scholes. (1973). The Pricing of Options and Corporate Liabilities, Journal of Political Economy 81, 637–659) and Merton (Merton, R. C. (1974). On the Pricing of Corporate Debt: The Risk Structure of Interest Rates, Journal of Finance 29, 449–470) (BSM) contingent claims model, and KMV Corporation framework, we estimate the distance to default and the “risk
neutral” default probabilities for a sample of 112 real estate companies over the period 1980 to 2001. Our empirical results
classifies failed and non-failed companies into Type I error, cases that the BSM-type model fails to predict default when
it did occur, and Type II error where BSM-type model predicts default when it did not occur. We find that none of the companies
belong to the category of Type I error. Type II error is observed in 12 out of 112 companies. These results support the theoretical
underpinnings of the BSM-type structural model in that the two driving forces of default are high leverage and high asset
volatility. 相似文献

We analyze the market assessment of sovereign credit risk using a reduced-form model to price the credit default swap (CDS) spreads, thus enabling us to derive values for the probability of default (PD) and loss given default (LGD) from the quotes of sovereign CDS contracts. We compare different specifications of the models allowing for both fixed and time-varying LGD, and we use these values to analyze the sovereign credit risk of Polish debt throughout the period of a global financial crisis. Our results suggest the presence of a low LGD and a relatively high PD during a recent financial crisis. 相似文献

The transaction price of identical housing units can vary widely due to heterogeneity in buyer and seller preferences, matching, and search costs, generating what we term “markups” above or below the average market price. We measure markups for 3.4 million purchase-money mortgages and show that they can predict mortgage defaults and credit losses conditional on default even after accounting for collateral coverage (loan-to-value ratio) and a comprehensive set of other covariates. The findings suggest that standard collateral coverage estimation may be inaccurate, with implications for both individual and portfolio-level credit risk assessment. 相似文献

经济资本是加强商业银行内部资本管理和风险管理的重要手段。借助经济资本和其他基于风险的管理工具,金融机构可以对其面临的风险进行量化,计算应对这些风险所需的资本及得出根据实际风险进行调整后的收益。对大多数国内银行而言,经济资本的应用已经落后于其他先进国家,本文试图从新资本协议IRB方法的基本思路入手,提出国内银行业在现有条件下提升经济资本计量水平的解决方案。并提出在目前条件下,为实现有效资本管理的最终目标,要尽快开发关键风险参数的量化模型,加强资本管理IT系统建设以及建立资本计划的制定和实施程序。 相似文献

We empirically examine the effect of appraisal quality on subsequent mortgage loan performance using data from the high volatility housing market of Alaska in the 1980s. We develop measures of appraisal quality by computing the residual between a hedonic estimate of house value using available information from other appraisals compared to actual ex ante appraised value. We then estimate proportional hazard models of mortgage default and find that several measures of appraisal quality, particularly appraised value in excess of hedonic estimates, are significantly related to default risk. Using valuations subsequent to loan default, we are also able to evaluate how well house price indices perform in terms of estimating current loan-to-value and offer some additional evidence on the controversy over the role of net equity versus trigger events as determinants of mortgage default. We also show that defaults are related to ex ante measures of housing market conditions, with additional implications for underwriting policies and the current industry trend away from traditional appraisal and toward automated valuation. 相似文献

This paper identifies and quantifies through a Bayesian Network model (BN) the various factors of Operational Risk (OR) associated with the payment process PROCAMPO. The BN model is calibrated with data from events that occurred during the period 2008-2011. Unlike classical methods, the BN model calibration sources include both objective and subjective ones, allowing to more adequately capture the relationship (cause and effect) between the several elements of operational risk. 相似文献
