当前我国金融体系的信用评级,无论是商业银行内部评级还是外部评级等,都程度不同的采用了AAA、AA、A、B、C这样离散的信用评级方法,本文从理论上讨论了违约率(广义)的定义、意义、分类标准和测算的方法,巴塞尔新协议中标准法,内部评级初级法,内部评级高级法的异同及对我国信用评级(广义违约率)管理建设的启示,指出我国商业银行的信用风险管理应采用内部评级高级法的框架,对于信用等级的评定应采用连续变量来代替传统的A、B、C等离散型的分类方法。 相似文献

内部信用评级是新巴塞尔资本协议的核心,而违约概率的预测又是内部评级的基础。本文利用具有出色分类功能的非线性支持向量分类(SVC)方法来预测德国公司的违约概率,识别其信用风险。结果显示,SVC模型的预测能力优于基准的logit模型;而且非线性SVC模型能够捕捉线性logit模型所不能识别的影响信用风险的重要变量。本文虽然分析的是德国公司数据,但是同样对我国商业银行和公司构建全面风险管理体系有着直接的指导意义。 相似文献

违约风险模型对违约定义的敏感性研究 总被引:1,自引:0,他引:1
本文根据贷款信用风险四级分类和五级分类定义三种违约,运用商业银行的贷款企业会计数据分析了Logistic违约风险模型对违约定义的敏感性。实证研究表明,在三种违约定义下,违约模型的结构相似,但模型选择的变量和变量的显著水平存在差异,违约模型对违约定义具有敏感性。 相似文献

个人住房抵押贷款违约风险跃迁概率研究 总被引:1,自引:0,他引:1
巴塞尔新资本协议提出针对个人住房抵押贷款可采用内部评级高级法评估其风险,在满足某些最低条件和披露要求的前提下,商业银行可根据自己对个人住房抵押贷款违约概率、违约损失率、违约风险暴露和期限等要素的估计值确定相应的资本要求。本文提出将风险跃迁概率引入到对个人住房抵押贷款提前还款-违约概率的定量估计中。借助逻辑斯特模型,本文将这一概念实际运用到对个人住房抵押贷款微观数据的分析当中,得到的实证研究结论包括借款人历史还款状态可以作为表征其未来还款状态的重要指标,贷龄与借款人还款状态的跃迁概率显著相关等。 相似文献

Using a measure of default likelihood based on an option pricing method, we provide evidence that Fed policy actions affect the financial distress of commercial banks. When the Fed increases (decreases) interest rates, the measure of default likelihood increases (decreases). We show that when the Fed uses a tight money policy, the increase in default likelihood is more pronounced for banks that have less capital, have greater financial leverage, are smaller, have fewer growth opportunities, and have lower asset quality. Additionally, the effects on bank default likelihood are more pronounced when the Fed's policy signals less concern about economic growth, as indicated by its bias toward further tightening, and when there is a market expectation of higher short‐term market rates in the future. 相似文献

This study investigates the effect of credit and liquidity risks as well as the moderating role of managerial ability on the likelihood of European commercial bank default during the period 2006 to 2017. We employ data envelopment analysis and a tobit model to measure banks' efficiency, the z-score to measure the likelihood of their default, and perform endogeneity and model specification robustness tests. Our results reveal that both risks significantly affect the likelihood of bank default and that the high skill of managers does not attenuate this effect. Rather, in the case of credit risk, managerial ability extenuates this effect. Managerial overconfidence and narcissism may explain the latter result. Another plausible explanation is that highly skilled managers who are likely to be rewarded with performance-based compensation schemes may be incentivized to hide bad news for an extended period of time. Such a scenario would increase the likelihood of bank default. 相似文献

We study whether tax considerations are an important determinant of commercial mortgage default. We also study whether large lenders are better informed, or better at interpreting information for lending purposes, and hence have lower foreclosure rates; whether lenders have more information on larger borrowers than smaller borrowers, and hence have lower foreclosure rates on larger loans; and whether commercial mortgage defaults are related to debt service coverage and loan-to-values, both initial and contemporaneous. The paper’s main findings are fourfold. First, holding all else equal, there is evidence that tax considerations influence investors’ decisions about when to “put” assets to lenders. The results are consistent with the argument of Constantinides (J Financ Econ 13:65–89, 1984). Second, the evidence suggests that large lenders are especially knowledgeable about commercial mortgage borrowers and commercial property markets, in that they have lower foreclosure rates than smaller lenders. Third, on the question of whether lenders have more information on larger borrowers than smaller borrowers, we find that larger loans have, on average, lower default rates than smaller loans. Fourth, the findings suggest that lower default rates are associated with higher debt service coverage ratios, both initial and contemporaneous. 相似文献

This study recognizes that commercial mortgage default is not a one-step process and examines a previously under explored aspect in the whole default process, that is the stage between the initial delinquency and default. We distinguish the servicers’ behavior from the borrowers’ behavior. A multinomial logit model is applied to analyze the servicers’ choice of workout options and a proportional hazard model is applied to analyze the borrower’s default decision-making process under time-varying conditions. We find that cash flow condition is the most significant factor in the servicers’ decision making process. We also find that borrowers make default decisions based upon both the equity position in the mortgage and the cash flow condition in the space market. Key real estate space market variables, such as market-level vacancy rates, also provide useful information in explaining commercial mortgage defaults. We find that special service seems to be successful in reducing the probability that a troubled loan will default. Finally, sensitivity analysis shows nontrivial economic significance of the impact of explanatory variables, real estate market variables in particular have the most significant impact on the pricing of special-serviced loans. 相似文献

本文以违约概率为小微企业风险的测度标准,建立了基于财务与非财务因素的小微企业风险计量模型。计量结果表明:除流动比率等少数指标外,大部分财务指标对判断小微企业违约概率不具有显著性;非财务因素中,反映小微企业资金状况的存贷比率指标具有较高的显著性,这说明现阶段部分商业银行在小微企业审查审批和贷后管理过程中将小微企业资金结算情况作为风险评价的重要依据,具有一定的科学性和准确性;小微企业的下游客户集中程度对判断小微企业违约概率也有较大的显著性,这说明小微企业的销售渠道是评价小微企业风险程度的重要要素。 相似文献

This study explores the relationship between credit risks of banks and the corporate governance structures of these banks from the perspective of creditors. The cumulative default probabilities are estimated for a sample of US commercial and savings banks to measure their risk taking behavior. The results show that one year and five year cumulative default probabilities are time‐varying, with a significant jump observed in the year prior to the financial crisis of 2008–09. Generally speaking, corporate governance structures have a greater impact on US commercial banks than on savings institutions. We provide evidence that, after controlling for firm specific characteristics, commercial banks with larger boards and older CFOs are associated with significantly lower credit risk levels. Lower ownership by institutional investors and more independent boards also have lower credit risk levels, although these effects are somewhat less significant. For all the banks in our sample, large board size, older CFO, and less busy directors are associated with lower credit risk levels. When we restrict the sample to consider the joint effects of the governance variables, the results on board size and busy directors are maintained. 相似文献

We employ Merton's probability of default as a continuous ex‐ante measure of the likelihood of firm failure and dynamic panel generalised method of moments to better characterise the relationship between corporate governance and the chance of default. In doing so, we overcome limitations of discrete proxies widely used in previous studies and more completely account for endogeneity issues permeating this area of research. While initial testing designed to facilitate comparison with previous studies suggests a significant relationship between the probability of default and executive pay, board structure and ownership structure, once endogeneity concerns are accounted for, no such relationship remains. 相似文献
