通过对信用风险缓释工具定价进行研究得出:(1)CRM定价的主要影响因素包括无风险基准利率,标的债券的风险敞口、违约概率、违约损失率和期限,以及CRM期限等。(2)同期国债利率和央行票据利率作为CRM的基准利率较为恰当,且模型定价对不同期限、不同信用等级的CRM定价区分度较为合理,模型定价与CRM发行交易定价较为接近,适合我国现阶段CRM产品定价。(3)可以从完善CRM定价基础数据库、探索CRM定价无风险基础利率、创新CRM标的债券评级制度、引导CRM市场主体多元化和优化CRM市场做市商制度等方面提出CRM定价优化对策。  相似文献

在成熟的债券市场,债券评级是债券发行必不可少的条件,也是投资者的投资依据之一,理论上对债券发行利率会产生直接的影响。我国债券市场发展尚不完善,信用评级的有效性也一直面临着诸多质疑。据此,本文重在研究我国债券评级对债券发行利率是否具有显著的影响力,是否具有市场公信力。本文利用计量模型开展实证分析,阐述了债券评级与发行利率在各种不同条件下的关系;对前述分析的过程进行了总结。  相似文献

本文通过计量分析发现评级机构给予的信用级别与商业银行债券的风险溢价显著相关,且当债券级别越高时,风险溢价越低;当商业银行债券以浮动利率发行时,债券的风险溢价能显著降低。同时,由于存款准备金率的变动影响了债券市场上的资金供需情况,当银行存款准备金率上升时,债券发行方商业银行需要向投资者支付更高的风险溢价。  相似文献

本文采用28个省市2010年至2012年地方政府债券的数据,使用eviews软件对其发行溢价的影响因素进行了回归分析。回归结果显示财政指标对地方政府债券的风险溢价没有显著影响,投资者的风险厌恶程度、市场利率与风险溢价有显著的相关关系。这表明地方政府债券的定价主要与市场因素相关,而与各省的财务状况无明显关联,这可能是由于地方政府发债刚启动,且由财政部代理发行,投资者对其信用情况普遍看好,因而没有明显的信用风险溢价。  相似文献

本文从利率期限结构的随机模型理论出发,应用Vasicek模型得到当前的利率期限结构的估计及其隐含的远期利率,进而确定浮动利率债券的未来收益率,再利用附息国债定价公式得到浮动利率国债的价格。实证研究表明,Vasicek模型确定的债券理论价格与市场价格相当吻合。  相似文献

本文基于理性预期理论,采用中国银行间市场交易商协会发布的"指导下限"作为市场成员事前对企业类债券发行利率的预期,建立了描述发行利率波动的模型。根据对2010年5月至2012年6月发行数据的分析,该预期能有效解释债券发行利率。本文同时发现债券种类和结构会影响债券发行利率,但债券回售和赎回条款未被有效定价。此外,准备金上调和负面信用事件冲击会导致债券发行利率升高。  相似文献

作为一种市场信号,金融认证机制可以为市场提供更多有关发行人的私人信息,有助于缓解债券投资者与发行人之间的信息不对称。本文采用多元线性回归模型,从信用评级认证、承销商认证和第三方担保认证三个角度分析了金融认证对城投债发行利率的影响,研究发现:第一,信用评级认证、承销商认证和第三方担保认证效果良好,能够降低城投债的发行利率;第二,城投债行政级别越高,金融认证效果越好;城投债行政级别越低,银行主承的效果越好;发行期限越长,信用评级认证效果越好。  相似文献

We examine the predictable components of returns on stocks, bonds, and real estate investment trusts (REITs). We employ a multiple-beta asset pricing model and find that there are varying degrees of predictability among stocks, bonds, and REITs. Furthermore, we find that most of the predictability of returns is associated with the economic variables employed in the asset pricing model. The stock market risk premium is highly important in capturing the predictable variation in stock portfolios, and the bond market risk premiums (term and risk structure of interest rates) are important in capturing the predictable variation in bond portfolios. For REITs, however, both the stock and bond market risk premiums capture the predictable variation in returns. REITs have comparable return predictability to stock portfolios. We conclude that there is an important economic risk premium for REITs that are not captured by traditional multiple-beta asset pricing models.  相似文献

The relationship between credit risk and the pricing of local government bonds in China is explored in this paper. The pricing of local government bonds was found to reflect credit risk, but the risk premium was small. The type of bond (‘directional’ or ‘non-directional’) significantly affected pricing. Repayment source had no effect. The authors make recommendations for the central government, local governments and investors.  相似文献

在完全有效市场条件下,信用风险是反映信用类债券特征的最基本信息,也是决定价差的关键因素。本文通过对中国信用类债券中短期融资券的价差分解发现,虽然信用风险显著影响短期融资券定价,但市场风险才是影响其价差的最主要因素。此外,市场流动性不足降低了市场运行效率,导致流动性溢价总体为负。上述研究结果表明我国短期融资券市场化的定价机制虽已初步形成,但市场效率总体仍然偏低。  相似文献

We examine the effects of liquidity, default and personal taxes on the relative yields of Treasuries and municipals using a generalized model with liquidity risk. The municipal yield model includes liquidity as a state factor. Using a unique transaction dataset, we estimate the liquidity risk of municipals and its effect on bond yields. Empirical evidence shows that municipal bond yields are strongly affected by all three factors. The effects of default and liquidity risk on municipal yields increase with maturity and credit risk. Liquidity premium accounts for about 9–13% of municipal yields for AAA bonds, 9–15% for AA/A bonds and 8–19% for BBB bonds. A substantial portion of the maturity spread between long- and short-maturity municipal bonds is attributed to the liquidity premium. Ignoring the liquidity risk effect thus results in a severe underestimation of municipal bond yields. Conditional on the effects of default and liquidity risk, we obtain implicit tax rates very close to the statutory tax rates of high-income individuals and institutional investors. Furthermore, these implicit income tax rates are quite stable across bonds of different maturities. Results show that including liquidity risk in the municipal bond pricing model helps explain the muni puzzle.  相似文献

共同因子是刻画风险溢价的重要基础,将共同因子模型应用于公司债券市场有助于合理估计信用风险溢价。本文利用机器学习算法探究债券信用溢价因子的存在性以及结构变化后发现:规模、下行风险、价值、波动率以及流动性等五个公司债券共同因子对单个债券信用溢价有较好的解释能力,动量因子对信用溢价的解释能力较差,流动性因子具有较强的逆周期防御性功能。债券市场以及公司债券信用溢价因子在2015年前后存在明显的结构变化,利用稀疏学习和集成学习可以有效分析因子结构变化,建立风险预警。此外,在公司债券市场的市场制度和环境改变过程中,可以利用机器学习算法识别其对市场的影响,防范化解潜在的系统性风险。  相似文献

This study explores the existence of inefficiencies in catastrophe (CAT) bond secondary markets by investigating the impact of sponsor characteristics on the CAT bond premium. We show that the CAT bond market does not satisfy the demand for catastrophe risk transfer efficiently by revealing a significant effect of sponsor-related factors on the CAT bond premium. This inefficiency is particularly surprising given that a CAT bond isolates the insured risk from other sponsor-related risks through a special purpose vehicle. Remarkably, this inefficiency is even present among non-indemnity CAT bonds, which determine the payout through a mechanism that is exogenous to the sponsor. Our findings also reveal that sponsor-related pricing inefficiencies vary over time and are more relevant during hard and neutral phases compared to soft market phases. Among the sponsor-related determinants of the CAT bond premium are the sponsor's tenure, market coverage, rating, credit default swap spread, and his ability to issue innovative “on the run” CAT bonds.  相似文献

The pricing of bonds and bond options with default risk is analysed in the general equilibrium model of Cox, Ingersoll, and Ross (1985). This model is extended by means of an additional parameter in order to deal with financial and credit risk simultaneously. The estimation of such a parameter, which can be considered as the market equivalent of an agencies' bond rating, allows to extract from current quotes the market perceptions of firm's credit risk. The general pricing model for defaultable zero-coupon bond is first derived in a simple discrete-time setting and then in continuous-time. The availability of an integrated model allows for the pricing of default-free options written on defaultable bonds and of vulnerable options written either on default-free bonds or defaultable bonds. A comparison between our results and those given by Jarrow and Turnbull (1995) is also presented.  相似文献

Under standard assumptions the reduced-form credit risk model is not capable of accurately pricing the two fundamental credit risk instruments – bonds and credit default swaps (CDS) – simultaneously. Using a data set of euro-denominated corporate bonds and CDS our paper quantifies this mispricing by calibrating such a model to bond data, and subsequently using it to price CDS, resulting in model CDS spreads up to 50% lower on average than observed in the market. An extended model is presented which includes the delivery option implicit in CDS contracts emerging since a basket of bonds is deliverable in default. By using a constant recovery rate standard models assume equal recoveries for all bonds and hence zero value for the delivery option. Contradicting this common assumption, case studies of Chapter 11 filings presented in the paper show that corporate bonds do not necessarily trade at equal levels following default. Our extension models the implied expected recovery rate of the cheapest-to-deliver bond and, applied to data, largely eliminates the mispricing. Calibrated recovery values lie between 8% and 47% for different obligors, exhibiting strong variation among rating classes and industries. A cross-sectional analysis reveals that the implied recovery parameter depends on proxies for the delivery option, primarily the number of available bonds and bond pricing errors. No evidence is found for a direct influence of the bid-ask spread, notional amount, coupon, or rating used as proxies for bond market liquidity.  相似文献

作为一种新型金融工具,巨灾风险债券自发行以来所附带的风险收益就远高于同等级传统债券的收益.尽管均值方差分析方法已证明"溢价之谜"确实存在,但从传统理论角度出发的研究并不能充分解释巨灾风险债券高溢价的成因.本文尝试用行为金融理论分析以获得较合理的解释补充.通过探讨投资者的心理、行为因素在巨灾风险债券溢价之谜中所起的重要作用,得出结论:风险厌恶、固定教育成本、模糊厌恶和羊群效应等行为导致了溢价之谜的出现.这些影响因素的发现不仅是对国际巨灾风险债券市场中的高溢价现象进行解释的重要依据,同时也为我国科学发行巨灾风险债券提供了思路.  相似文献
