零息票债券收益率曲线在利率风险度量和管理中有着基础性作用,商业银行等金融机构要对利率风险进行度量和管理,首先要构造零息票债券收益率曲线模型。而国债有利于消除期限以外的其他诸如违约风险等因素。我们按照实验要求以样条函数法对中国的国债进行研究,构造零息票债券收益率曲线。 相似文献

估值定价是机构投资者参与债券市场投资过程中经常面临的重要问题。本文从Nelson-Siegel估值定价模型入手,在均值回归理念下尝试引入期限利差这一关键变量计算出更为贴合市场变化的债券合意估值水平合市场变化的债券合意估值水平,以寻求实际价格与合意估值水平产生的有效套利空间,在提升估值定价准确性的同时优化模型输出结果,优化模型输出结果,文章最后对估值定价的影响因素、背后原因、理论依据以及实现方法进行总结。 相似文献

美国债收益率曲线自2018年底走平到目前出现的倒挂现象引发了市场和政策当局 的广泛关注。本文首先从收益率曲线的基本概念出发,回顾了历史上美国债券收益率曲线和经 济衰退之间的关系。研究发现,美国国债收益率曲线倒挂是预测美国经济衰退的一个较为可 靠的先行指标。然而,由于危机以来美联储货币政策操作模式已发生显著变化,此次收益率曲 线倒挂尽管仍可作为预测美国经济衰退的重要参考指标,但在可靠程度上可能会面临较大不 确定性。同时,又因美国目前的经济基本面总体向好,因此短期内发生经济衰退的可能性并不 大。最后,由于目前特朗普政府政策对美联储货币政策立场存在倒逼机制,因此未来政府政策 的不确定性或将成为左右美国经济走向的关键因素。 相似文献

中国国债收益率曲线构造的比较分析 总被引:7,自引:2,他引:7
随着我国国债期限结构的不断完善和收益率曲线模型研究的不断发展,采取恰当的方法构造中国国债收益率曲线具有理论和实践的双重重要意义。本文比较分析了目前我国构造国债收益率曲线的主要研究方法:直接方法、模拟方法、多项式样条函数法和扩展的Nelson-Siegel模型,认为用Nelson—Siegel模型构造中国国债收益率曲线最适合我国国债市场发展现状。 相似文献

直接法和间接法是零息票债券收益率曲线推导的两种方法.直接法作为一种代数方法,尽管存在对样本数量没有过高要求的优点,但存在对样本点的选取条件过于苛刻的缺陷;间接法作为一种统计方法,对样本点的选取条件相对宽松,但对样本数量有一定的要求.在中国现有的债券交易格局下,推导零息票债券收益率曲线存在一定困难. 相似文献

国债是我国债券市场的主体,也是我国债券市场的核心。国债收益率曲线形状及变动情况对金融市场具有重大的意义。因此,本文通过对某几个时点上各种国债的收益率进行计算,粗略作出国债收益率曲线。基于此对我国收益率曲线进行定性分析,并进一步分析出不同货币政策对我国国债收益率曲线的影响。 相似文献

This article investigates the source of predictability of emerging market (EM) local currency bond risk premia by using a dynamic factor approach based on a large panel of economic and financial time series. We find strong predictable variation in EM local currency excess bond returns that is associated with macroeconomic activity. We provide evidence that the main predictor variables are the factors based on real economic activity that are highly correlated with measures of industrial and manufacturing production; however, factors based on global financial factors also contain information about the future local currency bond returns. The predictive power of the extracted factors is both statistically significant and economically important. Our research has important implications for policymakers and pension fund managers. 相似文献

中国对大宗商品快速、持续的需求增长一直被认为是这十年大宗商品价格上涨的主要拉动因素。然而,与全球经济休戚相关的中国经济2008年不可能不受全球冲击而独善其身。预期中国GDP增长率在2008年下半年和2009年继续放缓。不确定的通胀前景、股价和房价下跌以及政策失误等宏观风险可能会相互作用并彼此增强。因此,中国需求增长放缓在近期可能会让过去五年全球大宗商品价格的猛涨态势稍作休整。 相似文献

金融监管对信用评级的需求
信用评级的需求有赖于整体经济的信用活动,我国信用评级的发展应当主要依赖银行信贷市场。这与我国长期依赖银行作为主要融资渠道,资本市场特别是债券市场发展滞后不无关系。但随着金融脱媒进程加速、债券市场快速发展以及资产证券化等金融创新产品的出现,银行作为信用中介和信息中介的功能相对弱化,直接融资逐渐成为资金市场上主要融资方式之一,银行的部分信息中介功能被信用评级替代。 相似文献

This paper studies reaching for yield—investors’ propensity to buy riskier assets to achieve higher yields—in the corporate bond market. We show that insurance companies reach for yield in choosing their investments. Consistent with lower rated bonds bearing higher capital requirements, insurance firms prefer to hold higher rated bonds. However, conditional on credit ratings, insurance portfolios are systematically biased toward higher yield, higher CDS bonds. This behavior is related to the business cycle being most pronounced during economic expansions. It is also characteristic of firms with poor corporate governance and for which the regulatory capital requirement is more binding. 相似文献

2018年,国内债券市场违约金额超过历年之和。完善市场化、法治化的违约债券处置机制,成为当前债券市场深化改革的重中之重。本文分析了目前对债券违约的主要处置方式。从实践看,发行环节保护不足、交易环节流转不畅和处置环节约束不强三大问题依然突出,尤其是违约债券无法市场化流转,成为市场呼声最大的痛点。2014年,佳兆业集团因境外美元债违约,成为首家在海外违约的内地房地产企业,但其通过历时2年的债券重组,成功走出困境。其间,违约债券可继续自由交易,以及条款的创新和完善的处置,为探索我国市场化债券违约处置机制及改革路径提供了有益借鉴。为破解国内违约债券的处置难题,本文建议,应尽快推出市场化流转机制,合理设计债券条款,以实现保护投资者和发行人的双重目的;同时,还应完善有关的法律制度。 相似文献

In a history that now stretches about four decades, the high yield (HY) market has experienced growth in issuance and out‐standings that is remarkable both for its level (about 13% per annum, with HY bonds now accounting for about 25% of the total corporate bond market) and its cyclicality and sensitivity to the broad economy. The HY market has also experienced a notable shift away from B‐rated bonds and toward both lower‐risk Ba‐rated bonds and, to a lesser extent, more risky Caa‐rated bonds. Consistent with this development, studies of the performance of HY bonds show Ba‐rated bonds experiencing not only lower risk, but also higher returns than Caa‐rated bonds, which have produced surprisingly low average returns along with exceptionally high volatility. At the same time, studies of the correlation of HY bond returns with returns on other major asset classes report that all classes of HY bonds (but particularly the riskier B‐ and Caa‐rated bonds) have consistently stronger relationships with common stocks (especially small‐cap stocks) than with Treasuries and investment‐grade bonds. Analysis of the volatility of HY bond returns over time shows that during periods of stability in the economy and financial markets, the volatility of HY bond returns has been very similar to that of investment‐grade bonds. But during periods of political or economic uncertainty, the volatility of HY bonds has become two or three times that of investment‐grade bonds, approaching the volatility of common stocks. The main driver of the significant increase in the risk of the aggregate HY bond market during periods of uncertainty has been Caa‐rated bonds, whose risk pattern has been remarkably similar to that of small‐cap common stocks. Analysis of the credit risk spread (or CRS) series for both the composite HY bond market and each of its rating categories shows markedly non‐normal distributions with significant positive “skewness”—that is, periods of exceptionally high spreads (that are not counterbalanced by periods of exceptionally low spreads). The authors also report a consistently strong relationship of the CRS series with default rates and the general state of the economy, with major peaks occurring during or shortly after economic recessions. Near the end of 2008, however, there was a clear break in this relationship when the CRS reached an historic peak of 2,000 basis points, or more than five standard deviations above its long‐term mean, while the default rate (at 4%) was below its long‐term average. The authors offer two explanations for this break in CRS‐default rate relationship: the jump in the CRS caused by the extreme flight to quality and drop in liquidity for all risky securities during the second half of 2008; and the use of covenant‐lite securities and other sources of financial flexibility that appear to have enabled many HY issuers to defer defaults (if not avoid them entirely). 相似文献
