我国商业银行资产证券化研究

资产证券化起始于上世纪70年代,孵化于美国金融市场,经过几十年的发展,已经成为国际资本市场发展最快、最具生命力的金融工具。资产证券化对于金融市场快速发展的中国同样具有重要意义,有利于优化金融市场结构、增加社会融资渠道,加深金融要素的流通,深化金融领域的创新。本文通过分析资产证券化在我国的发展历程,提出了我国商业银行资产证券化的必要性。     

The securitization of gold and its potential impact on gold stocks

We study the market impact of a very successful financial innovation – the SPDR Gold Trust exchange-traded fund (GLD). GLD holds physical gold, and provides traders with a convenient and cost-effective way to gain exposure to gold. We find that after the introduction of GLD, the liquidity of gold company stocks declined, and their adverse-selection risk increased. Over the two-month period after GLD’s introduction, the stocks’ relative effective bid-ask spreads increased by over 15%, while their adverse-selection cost, as measured by the price impact of trades, went up by more than 30%. Gold stocks also experienced significant negative abnormal returns (−12% on average) in the month after GLD started trading. Our findings suggest that GLD attracted traders, especially uninformed traders, away from gold company stocks, and that the resulting negative demand shocks and decrease in the stocks’ liquidity caused their prices to decline. Our results show that existing securities can be seriously adversely affected when a new security enters the market.     

The impact of securitization on credit rationing: Empirical evidence

We study whether banks’ involvement into different types of securitization activity – asset backed securities (ABS) and covered bonds – in Spain influences credit supply before and during the financial crisis. While both ABS and covered bonds were hit by the crisis, the former were hit more severely. Employing a disequilibrium model to identify credit rationing, we find that firms with banks that were more involved in securitization see their credit constraints more relaxed in normal periods. In contrast, only greater covered bonds issuance reduces credit rationing during crisis periods whereas ABS aggravates these firms’ credit rationing in crisis periods. Our results are in line with the theoretical predictions that a securitization instrument that retains risk (covered bond) may induce a more prudent risk behavior of banks than an instrument that provides risk transferring (ABS).     

Short-term safety or long-term failure? Empirical evidence of the impact of securitization on bank risk

Based on a sample of U.S. commercial banks from 2002 to 2012, this paper shows that bank loan securitization has a significant and positive impact on both Z-scores and the likelihood of bank failure, indicating a short-term risk reduction and a long-term risk increase effect. We also find disparate impacts between mortgage and non-mortgage securitization. Loan sale activities are found to have a similar impact to securitization.     

保险业在金融危机中的角色：资产证券化视角

本轮金融危机与次贷产品链条及其机理缺陷直接相关。本文对资产证券化中的两种保险机制在金融危机中扮演的角色做了探讨。研究发现：按揭保险业发挥了逆周期的稳定器功能,减缓了系统性风险对住房金融体系冲击。债券保险业较深介入次贷债券及其衍生品的供需链条之中,是导致本轮金融危机中系统性风险爆发的一环。在对二者不同的风险特征做了比较分析之后,结合中国实际,提出完善中国保险业业务结构的若干建议。     

“两房”与美国的住宅金融市场--兼论中国保障房融资机制创新

金融危机使“两房”和证券化倍受诟病。本文试图从历史、政治、经济、内生机制和外部市场环境等多个视角系统梳理美国住宅金融体制演变及“两房”和证券化的作用。通过梳理历史,客观评析了“两房”的创立对促进美国传统住宅金融向现代金融转变的积极作用,分析了网络经济泡沫破灭后金融市场环境和“两房”自身资产结构变化及诱发的危机的金融与实体经济因素。并着重剖析了后危机时代“两房”成为政府救市的工具运作机理和未来美国住宅金融市场改革的要点。最后提出我国保障房融资机制匮乏,应建立政策性住宅金融体系。     

旅游资产证券化的多元模式探讨——以桂林旅游为例

针对旅游资产证券化模式单一的问题,本文运用广义的资产证券化理论,从实体资产证券化的角度,对国内旅游酒店板块上市公司资产证券化的现状进行了比较研究,分析了旅游上市公司在资产证券化方面普遍存在的问题,并以桂林旅游为例从旅游信贷资产证券化的角度对资产证券化模式的多元化进行了探讨,提出了桂林旅游资产证券化的战略构想。     

基于合同能源管理项目的资产证券化分析

我国EPC项目融资难的原因之一是节能服务企业信用水平不足。资产证券化可以实现项目信用与企业信用分离,是一种值得探索的融资模式。本文尝试设计了基于EPC项目证券化融资的交易结构和交易流程,讨论了基于EPC项目进行证券化融资的要点。     

资产证券化流动性的系统协同分析

在系统协同视角下,资产证券化流动性具有三个层次,第一层次指被证券化资产的流动性,第二层次指资产支持证券的一级市场流动性,第三层次指资产支持证券的二级市场流动性,前两个层次流动性的成败最终取决于第三层次的流动性。资产证券化流动性的系统协同要素包括市场基础、工具创新以及风险监管。解决我国资产证券化流动性不足的出路在于层次和要素的系统协同。     

互联网金融企业资产证券化研究

近年来我国互联网金融迅猛发展,拥有广阔的前景,互联网金融与资产证券化(下文简称ABS)更是有着与生俱来的契合度。得益于互联网企业特性以及背后庞大的市场,仅数年间互联网金融就拥有了庞大的ABS市场。然而在学术领域,对于互联网金融ABS方面的研究相对不多,存在一定的滞后性,故而本文通过对15家互联网金融企业近4年(2017-2020)来的各项财务数据与ABS相关数据研究,探究互联网金融企业开展ABS的动因,研究影响发行ABS的规模决策因素。通过数据研究发现规模越大、信用越高、贷款业务量越大、增速越快的互联网金融企业越有发行互联网金融ABS的偏向并发行量越大,同时ABS的发行能降低企业风险,加快资产流动,极大的增加贷款业务量从而加强盈利能力,但却对风险有着明显的反作用力。所以互联网金融企业应加快合作转型,加强风险管控,社会政府应完善相应法规,加强监管。
