金融危机下中美两国利率互换市场的特征及互动性分析 总被引:1,自引:0,他引:1
以2008~2009年中美两国利率互换市场的日交易数据为样本,分析比较了影响两国利率互换利差的主要因素,进而实证研究了危机期间中美两国利率互换市场的动态互动效应。结果表明:两国利率的水平和利率期限结构斜率是影响互换利差的主要因素,另外,中国的流动性溢价和美国的违约溢价对互换利差的影响也较为显著;研究发现:中美两国互换利差均受对方市场因素的影响,特别地,在金融危机期间,中美两国利率互换市场间存在着明显的互动效应,一方面,美国利率互换市场信息能够对中国利率互换市场产生较强的冲击,虽然冲击的程度受制于美国的经济状况;另一方面,中国市场对美国市场也形成了一定的反向冲击,且程度受制于中国的货币政策。 相似文献

The recent financial crisis highlights the inherent weaknesses of the financial market. To explore the mechanism that maintains the financial market as a system, we study the interactions of U.S. financial market from the network perspective. Applied with conditional Granger causality network analysis, network density, in-degree and out-degree rankings are important indicators to analyze the conditional causal relationships among financial agents, and further to assess the stability of U.S. financial systems. It is found that the topological structure of G-causality network in U.S. financial market changed in diferent stages over the last decade, especially during the recent global financial crisis. Network density of the G-causality model is much higher during the period of 2007–2009 crisis stage, and it reaches the peak value in 2008, the most turbulent time in the crisis. Ranked by in-degrees and out-degrees, insurance companies are listed in the top of 68 financial institutions during the crisis. They act as the hubs which are more easily influenced by other financial institutions and simultaneously influence others during the global financial disturbance. 相似文献

尽管赢得了一部分贸易保护主义者的喝彩,美国国会参议院通过的《2011年货币汇率监督改革法案》,仍然理所当然地在国内外激起了反对声浪。且不提今日之中国早已不是1934年美国实施《购银法案》时的中华民国,中美综合国力对比及其变动趋势正在削减美国强制施行这份法案的能力;且不提这份法案一旦付诸实施将对中美经贸、乃至全球贸易体系和全球金融市场产生核武器般的冲击,以至祸及美国自身;仅仅从美国自身的立场看, 相似文献

金融市场中的风险资产的演化过程遵从某种统计规律。这种统计规律通常是采用经典概率理论来加以阐述的。最近, 作者提出了从量子力学的角度来探讨金融问题的设想[1],[2],[3]。其中, 作者不仅从量子力学的角度用Maxwell Boltzmann统计重新推导了著名的Cox Ross Rubinstein期权定价公式,而且还用量子力学中的Bose Einstein统计(不可分辨粒子模型)得到了一个新的期权定价公式。这表明在理论上存在着一套关于金融市场的和谐的“量子理论”——量子金融。本文从对冲的角度来阐述这种潜在理论的金融意义和可能的实际内涵。作者给出了对冲定价的量子方案,详细讨论了单期金融市场的量子对冲问题。最后,作者解释了为什么(某些)金融市场在物理上要遵循量子规律,而不是经典统计规律。 相似文献

It was shown in Xia that for incomplete markets with continuous assets' price processes and for complete markets the mean-variance portfolio selection can be viewed as expected utility maximization with non-negative marginal utility. In this paper we show that for discrete time incomplete markets this result is not true. 相似文献
