Credit ratings from the major rating agencies failed to signal the true risk content of residential mortgage-backed securities (RMBS), collateralized debt obligations (CDOs), and commercial mortgage-backed securities (CMBS) issued from 2005 through 2007. This article compares the failures across rating agencies and asset classes, using data filed by the rating agencies with the Securities and Exchange Commission (SEC). The data confirm the terrible performance of RMBS ratings. The likely causes include a combination of the breakdown of mortgage industry lending practices and the concurrent deterioration of rating agency practices. The data show that CDO ratings perform somewhat better than RMBS ratings. That result is perhaps surprising and likely reflects the confounding effects of the SEC’s definitions of its reporting categories. The data also show bad performance for CMBS ratings although the underlying causes differ from those driving the results for RMBS and CDOs. Moreover, the data show high levels of rating withdrawals across all asset classes, raising the question of possible underreporting of defaults. Key Findings ▪ Rating agency data reported to the SEC confirm the terrible performance of RMBS ratings, with triple-A-rated RMBS displaying 10-year default rates of 30% to 35% as of year-end 2017. The likely causes include a combination of the breakdown of mortgage industry lending and securitization practices and the concurrent deterioration of rating agency practices. ▪ The data show that CDO ratings performed better than RMBS ratings, likely because the data include ratings for many synthetic corporate CDOs. Other studies indicate that performance is significantly worse for CDOs backed by structured finance assets. ▪ CMBS ratings also performed poorly. Although CMBS rated triple-A displayed 10-year default rates of only 2% to 3%, those rated double-A had default rates of 12% to 19% while single-A-rated CMBS default rates were 23% to 32%. ▪ The data document high levels of unexplained rating withdrawals on structured finance securities. The effect of such withdrawals may be to artificially depress the reported default rates.
主要评级机构的信用评级未能表明2005年至2007年发行的住宅抵押贷款支持证券(RMB S)、债务抵押债券(CDO)和商业抵押贷款支持债券(CMBS)的真实风险内容。本文使用评级机构向美国证券交易委员会(SEC)提交的数据,比较了评级机构和资产类别的失败情况。这些数据证实了人民币S评级的糟糕表现。可能的原因包括抵押贷款行业贷款实践的崩溃和评级机构实践的同时恶化。数据显示,CDO评级的表现略好于人民币S评级。这一结果可能令人惊讶,可能反映了美国证券交易委员会对其报告类别的定义所产生的混淆效应。数据还显示,CMBS评级表现不佳,尽管根本原因与推动RMB S和CDO评级结果的原因不同。此外,数据显示,所有资产类别的评级撤销率都很高,这引发了违约报告可能不足的问题。关键发现▪ 向美国证券交易委员会报告的评级机构数据证实了人民币S评级的糟糕表现,截至2017年底,三A级人民币S的10年违约率为30%至35%。可能的原因包括抵押贷款行业贷款和证券化实践的崩溃,以及评级机构实践的同时恶化。▪ 数据显示,CDO评级表现好于RMB S评级,可能是因为该数据包括了许多合成企业CDO的评级。其他研究表明,由结构性金融资产支持的CDO的表现要糟糕得多。▪ CMBS评级也表现不佳。尽管评级为AAA的CMBS 10年期违约率仅为2%至3%,但评级为双A的CMBS违约率为12%至19%,而评级为A级的CMBS的违约率为23%至32%。▪ 该数据记录了结构性金融证券的高水平无法解释的评级撤销。这种提款的效果可能是人为压低报告的违约率。

The true lender rule issued by the Office of the Comptroller of the Currency (OCC) briefly provided a uniform standard that could be applied to determine when a national bank is acting as a lender when it partners with other service providers. The rule was lauded for its objective standard that respected the form of legal documentation. The fintech marketplace lending platforms and banks that have been doing business for years under a bank partnership model viewed the rule as a welcome sign that the OCC did not support state efforts to recast the marketplace lending platforms as the true lender as a way to impose state law usury rules against national banks. Then Congress invalidated the rule under the Congressional Review Act (CRA) within six months of its effective date. Did the bank partnership model take one step forward and two steps back? In this article, we explore “true lender” issues, existing litigation and regulatory developments, and the implications following the invalidation of the rule.
美国货币监理署(OCC)发布的真正贷款人规则简要地提供了一个统一的标准,可用于确定一家国家银行在与其他服务提供商合作时何时充当贷款人。该规则因其尊重法律文件形式的客观标准而受到称赞。多年来一直在银行合作模式下开展业务的金融科技市场借贷平台和银行认为,这一规定是一个可喜的迹象,表明OCC不支持州政府将市场借贷平台重塑为真正的贷款人的努力,不支持州政府对全国性银行实施州法律高利贷规则的做法。随后,国会根据《国会审查法案》(Congressional Review Act, CRA)在该规定生效后6个月内宣布其无效。银行合作模式是否前进了一步,后退了两步?在本文中,我们将探讨“真正的贷款人”问题、现有的诉讼和监管发展,以及该规则无效后的影响。

The aviation industry is undergoing a series of layered dynamic effects to the entire business model value chain including aviation finance, leasing, and associated structured products. COVID has caused an historical exogenous demand shock and global airlines have suffered greatly; recovery is varied and uneven. There is a divergence of what has occurred since COVID and outlook geographically among the airlines (end-users), their lessors, and all of the various stakeholders in financing structures, such as aircraft asset backed securities (ABS) and enhanced equipment trust certificates (EETCs) that make up the capital structure. Debt funding has been robust for airlines with access to the capital markets, but others are less fortunate and are finding it more difficult. Financing options are diverse but are restricted among the players, given the effects of COVID. Pricing and structuring characteristics are all affected by these conditions. Key Findings ▪ COVID has changed the structure of demand for aircraft, and it has impacted both financing of aircraft lessors and the airlines with different effects geographically. ▪ Airlines face a bifurcation of opportunity, between larger or state-supported airlines with access to the public debt capital markets or government subsidy and smaller airlines, which have had to fall back on private capital in a challenging environment. ▪ The aircraft ABS and EETC financing environments continue to have pressures from downward aircraft pricing and 2 EETC issuance winddown cases.
航空金融、航空租赁及相关结构性产品等整个商业模式价值链正在经历一系列分层动态效应。新冠肺炎疫情造成了历史性的外生需求冲击,全球航空公司遭受重创;复苏是多种多样且不均衡的。自2019冠状病毒病以来,航空公司(最终用户)、出租人以及构成资本结构的飞机资产支持证券(ABS)和增强型设备信托证书(EETCs)等融资结构中的所有利益相关者之间的情况和地理前景存在分歧。对于能够进入资本市场的航空公司来说,债务融资一直很强劲,但其他航空公司就没那么幸运了,而且发现融资更加困难。融资选择多种多样,但由于COVID的影响,参与者之间的融资选择受到限制。定价和结构特征都受到这些条件的影响。■新冠肺炎改变了飞机需求结构,并对飞机出租人和航空公司的融资产生了不同地域的影响。•航空公司面临着机遇的分化,一方面是获得公共债务资本市场或政府补贴的大型或国家支持的航空公司,另一方面是在充满挑战的环境中不得不求助于私人资本的小型航空公司。▪飞机ABS和EETC的融资环境继续受到飞机价格下降和2个EETC发行终止案例的压力。

Automatic Spline Knot Selection in Modeling Mortgage Loan Default Using Shape Constrained Regression 基于形状约束回归的抵押贷款违约建模中样条节点的自动选择

In mortgage default modeling, many of the key variables, such as loan age, FICO score, Debt-to-Income ratio (DTI), and Loan-to-House-Value ratio (LTV), have nonlinear relationships with the target default rates. Experienced modelers generally apply a spline transformation with knots to the individual variables. In this article, we introduce the Quantile-based Shape Constrained Maximum Likelihood Estimator (QSC-MLE), which features an automatic spline knot selection in a mortgage default model. QSC-MLE is an enhanced variant of SC-MLE (Chen and Samworth 2016) used in combination with a quantile-based knots set, to effectively process large datasets. QSC-MLE requires generic shape information of the inputs, for example, the monotonicity or convexity of the FICO score, DTI, and LTV, to capture any nonlinear effects. We show that the new default model considerably improves the accuracy of the out-of-sample prediction in comparison with the logistic regression and the Cox proportional hazards model. Moreover, the model conveniently generates component-wise spline functions, which facilitates the interpretation of the default rate response to the input variables. Key Findings ▪ A mortgage default model using the Quantile-based Shape Constrained Maximum Likelihood Estimator (QSC-MLE), which features automatic spline knot selection. ▪ QSC-MLE constructs shape-constrained spline functions to capture nonlinear effects of model inputs. ▪ The new default model considerably improves the accuracy of the out-of-sample prediction.
在抵押贷款违约建模中,许多关键变量,如贷款年龄、FICO评分、债务收入比(DTI)和贷款房屋价值比(LTV),与目标违约率具有非线性关系。经验丰富的建模师通常会将带有节点的样条曲线变换应用于各个变量。在本文中,我们介绍了基于分位数的形状约束最大似然估计器(QSC-MLE),该估计器在抵押贷款违约模型中具有自动样条曲线节点选择的特点。QSC-MLE是SC-MLE(Chen和Samworth 2016)的增强变体,与基于分位数的节点集结合使用,以有效处理大型数据集。QSC-MLE需要输入的一般形状信息,例如FICO分数、DTI和LTV的单调性或凸性,以捕捉任何非线性效应。我们表明,与逻辑回归和Cox比例风险模型相比,新的默认模型显著提高了样本外预测的准确性。此外,该模型方便地生成分量样条函数,这有助于解释对输入变量的默认速率响应。关键发现▪ 使用基于分位数的形状约束最大似然估计(QSC-MLE)的抵押贷款违约模型,该模型具有自动样条曲线节点选择功能。▪ QSC-MLE构造形状约束样条函数来捕捉模型输入的非线性效应。▪ 新的默认模型大大提高了样本外预测的准确性。

Why We Tend to Be Unprepared for the Inevitable Next Disaster 为什么我们往往对不可避免的下一场灾难毫无准备
IF 0.4 Q4 Economics, Econometrics and Finance Pub Date : 2021-04-30 DOI: 10.3905/jsf.2020.1.108
Martin Goldberg
It is human nature to be unprepared for rare catastrophic events. Human nature includes inclinations toward optimism, optimizing for best performance if nothing changes, linear thinking, innumeracy, inertia, greed, a desire to fit in with the crowd, and myopia. Thus, being prepared for an unknown future disaster of an unknown type requires going against human nature. TOPICS: Risk management, legal/regulatory/public policy, behavioral financial theory Key Findings • Human nature has not changed since modern humans evolved. • Myopic linear thinking, inertia, greed, and social pressure lead to optimizing for what would be the best results if conditions never changed. • Resiliency when conditions change requires actively preparing for events that may never happen, which is rarely part of human nature.
对罕见的灾难性事件毫无准备是人之常情。人性包括乐观主义倾向、在不变的情况下优化最佳表现、线性思维、数不胜数、惰性、贪婪、融入人群的欲望和近视。因此,为未知类型的未知未来灾难做好准备需要违背人性。主题:风险管理、法律/监管/公共政策、行为金融理论关键发现•自现代人类进化以来,人性没有改变。•近视的线性思维、惯性、贪婪和社会压力会导致在条件从未改变的情况下优化最佳结果。•当情况发生变化时,要有韧性,就需要为可能永远不会发生的事件积极准备,而这很少是人性的一部分。
