信用违约互换作为一种信用衍生产品通过转移信用风险为信用风险管理带来了深刻变化,其定价问题值得深入研究.通过对违约强度的建模给出两种违约模型——结构性模型、简约模型,结合信用评级制度发现了一个公司的违约强度与其所处的评级之间的关系,使用马尔科夫链建模该公司的信用等级转移状况证明其违约强度为马氏调节过程.该模型增加了模型参数,得出了具有较强操作性的信用违约互换定价公式,并对金融危机下信用违约互换的前景进行了展望.  相似文献

为了研究信用违约互换(CDS)的价格,本文在现金流分析法的基础上提出了信用违约互换(CDS)定价的。首先,分析了保护购买方定期支付的预期保费、保护买需要支付给保护购买方的赔偿额;然后,在对两个部分进行分析,建立所需模型;最后,对该定价模型进行论证分析,分别研究无风险下的利率、合同的有效期以及信用评级这三方面对信用违约互换(CDS)定价的影响。  相似文献

本文研究了信用违约互换的引入对于公司股票流动性的影响。一方面,在信用违约互换引入之后,债权人的违约风险得到转移,故对于债务公司运营以及对于债务管理的监管力度有所降低,增加债务的违约风险;另一方面,人们会对于信用违约互换的引入作为违约风险较高的一个信号。实证结果显示,引进信用违约互换会对公司股票的流动性产生负面的影响。  相似文献

信用违约互换   总被引:1,自引:0,他引:1  
信用违约互换(credit default swap,CDS)是指信用违约互换的购买者(以下简称买方)向信用违约互换的出售者(以下简称卖方)转移第三方信用违约风险的信用衍生产品.在信用违约互换交易中,买方定期向卖方支付一定费用,而一旦出现第三方信用违约(主要指债券主体无法偿付),买方有权利将债券以面值出售给卖方,从而有效规避信用风险.由于信用违约互换产品定义简单、容易实现标准化,交易简洁,自1990年代以来得到了迅速发展.目前国外信用违约互换市场规模相当庞大,而且流动性强.  相似文献

一、引言信用违约互换是一种双边风险交换金融契约,在该契约中,由信用保护买方定期向信用保护卖方支付一定的费用,当合约期限内双方确定的参照资产(贷款或者债券)因信用事件而发生损失时,由信用保护卖方支付一定的金额弥补信用保护买方所遭受的损失。信用违约互换的定义如图1所示:图1信用违约互换定义结构示意图通过上述定义示意图,我们可以知道合约买卖双方在信用违约互换合约生效前应该就有关事项达成一致。这其中包括参照信用资产、信用事件、信用违约互换的价格(定期支付的固定费用)、合约的期限。二、基于现金流分析的信用违约互换定价模型任何金融资产的价格都可以由其期望现金流的现值给出,因此,我们可以通过分析信用违约互换的现金流来确定其价值。根据信用违约互换的定义可知,在一份信用违约互换协议中,可能存在着两部分的现金流。第一部分为保护买方支付的现金流,是指其在合约期限内信用事件发生前定期支付给保护卖方的费用。而另一部分现金流是保护卖方支付的现金流,如果不发生信用事件,则保护卖方无需支付任何费用,如果发生信用事件,则保护卖方在违约发生时向保护买方支付违约损失额。信用违约互换的现金流分析如图图1信用违约互换现金流量图注:图中t0为合约起始时...  相似文献

美国信用违约互换带给市场的动荡及可资借鉴的教训   总被引:1,自引:0,他引:1  
作为一种新型金融产品,信用违约互换试图为投资者提供固定收益投资的违约保护,但是在市场资产证券化过程中,该产品却使得信用风险更广泛地分散在固定收益市场中,从而构成了信用风险向体系性风险转化的潜在基础。除产品设计与市场营销策略等技术因素外,信用违约互换市场能否有效扩展实际上是有赖于以下三种因素:一是卖出方是否具有实际最终偿付能力;二是市场对于产品核心风险的评估与产品定价机制是否具有客观而统一的标准;三是买方机构的营利来源及大规模购买产品的意愿。信用违约互换技术上的设计可以说在一定程度上解决了衍生产品的操作风险,但从根本上讲并未有效化解交易相关的信用风险和市场风险。在2007年9月爆发的美国次贷危机中,信用违约互换也起到了推波助澜的作用,使风险散播到更大范围的市场层面,引起了体系性风险的扩大。该文的案例分析,使我们能够更清楚地了解次贷危机所凸显出的风险控制对于金融业务与产品创新的重要意义。  相似文献

The role of credit default swaps (CDS) in the 2008 financial crisis has been widely debated among regulators, investors, and researchers. While CDS were blamed for destabilizing the financial system, they remain effective tools for hedging credit risk, especially for major banks, and produce positive informational externalities to market participants. This paper examines whether the introduction of CDS enhances the amount of firm-specific information impounded in stock prices. We use stock return synchronicity to measure the amount of firm-specific information reflected in stock prices, with more firm-specific information being associated with a lower level of synchronicity. We find that a firm’s stock return synchronicity decreases after the commencement of CDS trading. This finding is robust to different model specifications, synchronicity measures, and endogeneity controlling methodologies. Furthermore, the decrease in stock return synchronicity is more pronounced for CDS firms with higher credit risk. Overall, our evidence supports the positive role of CDS in improving informativeness of stock prices.  相似文献

Prior literature indicates that quadratic models and the Black–Karasinski model are very promising for CDS pricing. This paper extends these models and the Black [J. Finance 1995, 50, 1371–1376] model for pricing sovereign CDS’s. For all 10 sovereigns in the sample quadratic models best fit CDS spreads in-sample, and a four factor quadratic model can account for the joint effects on CDS spreads of default risk, default loss risk and liquidity risk with no restriction to factors correlation. Liquidity risk appears to affect sovereign CDS spreads. However, quadratic models tend to over-fit some CDS maturities at the expense of other maturities, while the BK model is particularly immune from this tendency. The Black model seems preferable because its out-of-sample performance in the time series dimension is the best.  相似文献

主权CDS对欧元区主权债务危机的影响   总被引:1,自引:0,他引:1  
本文概括了主权CDS是否影响欧元区主权债务危机的几种观点和研究,发现了其中的不足之处,并试图进行弥补。文章基于面板数据,在对样本区间和国家进行分组的基础上,用向量误差修正模型(VECM)检验了主权CDS息差与国债息差的价格发现过程,此外还用向量自回归(VAR)模型分析了各国主权CDS息差之间的传染效应。结果发现,虽然主权CDS在价格发现过程中占据领先地位,但是没有证据表明主权CDS与主权债务危机之间存在必然的联系,而各国债务危机之间确实存在传染效应。  相似文献

This paper proposes a model for credit default swap (CDS) spreads under heterogeneous expectations to explain the escalation in sovereign European CDS spreads and the widening variations across European sovereigns following the Global Financial Crisis (GFC). In our model, investors believe that sovereign CDS spreads are determined by country-specific fundamentals and momentum. By estimating the model we find evidence that, while some of the recent movements in sovereign CDS spreads can be explained by deteriorating fundamentals for core European Union (EU) countries, momentum has also played a destabilizing role since the GFC in all sovereign credit markets studied.  相似文献

We examine the effect of introducing credit default swaps (CDSs) on firm value. Our model allows for dynamic investment and financing, and bondholders can trade in the CDS market. The model incorporates both negative and positive effects of CDSs. CDS markets lead to more liquidations, but they also reduce the probability of costly debt renegotiation and reduce costly equity financing. After calibrating the model, we find that firm value increases by 2.9% on average with the introduction of a CDS market. Firms also invest more and increase leverage. The effect on firm value is strongest for small, financially constrained, and low productivity firms.  相似文献

This paper examines the size and power of test statistics designed to detect abnormal changes in credit risk as measured by credit default swap (CDS) spreads. We follow a simulation approach to examine the statistical properties of normal and abnormal CDS spread changes and assess the performance of normal return models and test statistics. Using daily CDS data, we find parametric test statistics to be generally inferior to non-parametric tests, with the rank test performing best. A CDS factor model based on factors identified in the empirical literature is generally well specified and more powerful in detecting abnormal performance than some of the classical normal return models. Finally, we examine abnormal CDS announcement spread changes around issuer's rating downgrades to demonstrate the effect of different CDS spread change measures and normal return models on event study results.  相似文献

We study the design of credit default swaps (CDS) auctions, which determine the payments by CDS sellers to CDS buyers following defaults of bonds. Using a simple model, we find that the current design of CDS auctions leads to biased prices and inefficient allocations. This is because various restrictions imposed in CDS auctions prevent certain investors from participating in the price discovery and allocation process. The imposition of a price cap or floor also gives dealers large influence on the final auction price. We propose an alternative double auction design that delivers more efficient price discovery and allocations.  相似文献

A credit default swap (CDS) contract provides insurance against default. This paper incorporates the contract into a sovereign default model and demonstrates that the existence of a CDS market results in lower default probability, higher debt levels, and lower financing costs for the country. Uncertainty over the insurance payout when the debt is renegotiated explains why in the data, as the output declines, the CDS spread becomes lower than the bond spread. Finally, my results show that the 2012 CDS naked ban, that decreased the levels of CDS for European countries, is a welfare reducing policy.  相似文献

We use daily data for a panel of 34 countries to investigate regional differences in sovereign credit default swaps (CDS) spread determinants and the significance of local versus global market factors. Similar to prior studies, we find a high level of commonality among CDS spreads, but our results show that this effect is stronger in Latin American CDS. The results of our quantile panel regression model show that although global forces drive spreads across the conditional distribution, changes in credit ratings are significant in explaining CDS spreads only in the upper quantiles. We also confirm the existence of regional differences in spread determinants.  相似文献

We theorize and confirm a new channel by means of which liquidity costs are embedded in CDS spreads. We show that credit default swap (CDS) spreads are directly related to equity market liquidity in the Merton [Merton, R.C., 1974. On the pricing of corporate debt: The risk structure of interest rates. J. Finance 29, 449–470] model via hedging. We confirm this relationship empirically using a sample of 1452 quarterly CDS spreads over 2001–2005. In the model, this relationship is monotone increasing when credit quality worsens. These results are robust to alternative measures of equity liquidity and other possible determinants of CDS spreads.  相似文献
