人民币境外衍生市场与境内即期市场间的信息流动关系研究

本文基于Granger因果检验和GARCH模型从线性报酬溢出效应和非线性波动率溢出效应两个角度实证研究了人民币境外衍生市场与境内即期市场间的信息流动关系.研究结果表明:在报酬溢出方面,境外CME期货市场与境内即期市场之间存在双向影响关系,但境外NDF远期市场对境内即期市场仅存在单向的影响关系;在波动率溢出方面,境外CME期货市场和境外NDF远期市场都对境内即期市场存在波动率溢出效应,而境内即期市场对境外CME期货市场存在波动率溢出效应,但对境外NDF远期市场的波动率溢出效应不显著.     

人民币境外NDF汇率、境内远期汇率与即期汇率的关系的实证研究

2005年7月21日汇率形成机制改革以来,人民币即期汇率波动幅度加大,企业和居民面临的汇率风险加大。在远期市场上,套期保值是规避汇率风险的常用办法。当前经营人民币远期产品的市场主要有两类,一类是境外NDF市场,另一类是境内远期外汇市场,包括银行间远期市场和远期结售汇市场。本文检验了境外NDF市场、境内远期外汇市场和即期外汇市场上人民币汇率的协整关系以及两类远期外汇市场的有效性。对各市场汇率时间序列进行的格兰杰因果检验表明国内远期外汇市场是人民币外汇市场的信息中心。最后,文章对当前的外汇管制政策进行了分析评论。     

境外人民币NDF和境内人民币掉期之间关系的实证研究

我国2005年7月21日启动人民币汇率形成机制改革以来,人民币汇率波动性显著放大,各经济主体运用人民币远期产品规避汇率风险的需求增加。本文运用协整检验、Granger因果关系检验、ECM模型和脉冲响应函数,运用交易比价活跃的5个期限的人民币远期产品对境外人民币NDF隐含掉期点数和境内人民币市场掉期点数之间的关系进行了实证分析并对其作用机制进行了讨论。结果表明,在各个期限的远期产品上,境外NDF隐含掉期点数和境内人民币掉期点数之间存在长期正向的协整关系,其中NDF处于主导地位。     

人民币NDF对境内人民币即期汇率的影响

本文以境外人民币NDF(无本金交割远期)市场和境内人民币即期市场为研究对象,选取2010年8月至2013年11月间1个月、3个月、6个月及1年期人民币NDF汇率和境内即期汇率作为样本数据,通过Granger因果检验分析了两个市场之间的价格引导关系。实证结果表明,境外人民币NDF(无本金交割远期)市场不存在对境内人民币即期市场的价格引导,而境内即期汇率却是人民币NDF汇率变动的先导变量。     

人民币离岸NDF汇率与境内人民币汇率关系的实证

人民币汇改以来,人民币离岸NDF市场的交易日趋活跃,对人民币汇率走势预期的影响也日渐增强.实证结果表明,人民币离岸NDF 市场上存在着不同程度的人民币升值预期,预期升值水平与NDF汇率期限相关;人民币离岸NDF汇率影响着人民币即期汇率,离岸NDF市场对人民币即期市场存在单向波动溢出效应,在信息传递上表现为人民币离岸NDF市场的汇率信息向境内人民币市场传递.     

境内外人民币汇率衍生产品发展比较研究

本文首先分别分析了境外和境内人民币汇率衍生产品市场的基本状况,包括市场规模、交易主体和产品类型等,并比较了境内外市场的优势和劣势;然后运用计量的方法分析境内外市场的联动性,实证分析表明,境外NDF市场定价更为准确,但境内人民币汇率衍生品市场定价更为稳定,前者相对后者具有一定的主导地位.最后,本文指出发展我国人民币汇率衍生品市场具有必要性和紧迫性,应从提高人民币汇率定价权着手,完善制度建设并加强市场监管.     

人民币即期汇率与NDF的关联性：对NDF限制政策的实证研究

检验和揭示境内人民币即期汇率与境外NDF间的互动关系,可为各类市场主体提供有益的市场信息和参考.本文针对2006年10月出台的对境内机构和个人参与境外人民币NDF交易的限制性政策,实证研究了该政策实施后人民币即期汇率与NDF的相互影响.格兰杰因果性检验表明:即期汇率引导12个月期限的NDF;12个月期限的NDF不引导即期汇率.境内现汇市场显现出本土信息优势.在一定程度上说明人民币汇改和限制性措施的成效性,但限制性政策却可能并非长远之计.     

境内人民币远期与NDF汇率关系

对2006年8月11日至2009年11月30日1月期、3月期、6月期和12月期的远期汇率进行统计和计量分析后发现:金融危机后,境内人民币远期汇率与NDF汇率的总体波动性有所降低,人民币远期汇率弹性有所下降;境内人民币远期市场的定价能力提高主要体现在短期限品种NDF汇率对于境内人民币远期汇率单向引导关系减弱,而二者的相互引导关系增强;长期限品种NDF汇率对于境内人民币远期汇率的引导关系不变。因此后金融危机时期一方面要防范国际资本和政治经济压力对中国汇率的冲击,同时也要择机有序退出临时性汇率安排,稳步推进人民币汇率形成机制改革。     

市场因素对人民币汇率的效应研究——基于境内即期汇率与香港离岸即期以及NDF汇率的分析

香港离岸人民币市场在最近几年得到中国政府的大力支持,它的发展不仅可以提高香港作为国际金融中心的地位,而且可以有效地推动人民币国际化。由于香港离岸人民币市场的建立标志着中国的资本市场将更加开放,因此研究香港离岸人民币汇率变化对市场因素的反映情况就有很现实的意义。根据以往的研究,人民币NDF市场汇率较好地反映了市场因素。因此本文将境内即期人民币汇率与香港离岸人民币汇率对NDF市场汇率进行比较,分析市场因素在人民币境内即期汇率和香港离岸汇率变化中的影响程度。实证分析的结论为:香港离岸人民币汇率更大程度上地反映了市场因素的作用,并且1年期NDF汇率是香港离岸汇率的Granger原因;而境内即期人民币汇率不能很好的反映市场因素的作用,与NDF市场汇率之间没有长期协整关系。     

基于人民币NDF汇率与境内即期汇率的实证研究

本文通过对人民币NDF市场汇率与利率平价理论远期汇率的检验证明,前者与境内即期汇率、境内外利率之间存在传导机制。通过对即期汇率与各期限NDF汇率进行协整检验,以及在此基础上对两者进行格兰杰因果检验,分析两者的相互引导关系。结果表明,即期汇率与各期限NDF汇率都存在较为显著的协整关系,并且即期汇率处于信息传导机制中心。     

Information Flows Between the U.S. and China Commodity Futures Trading

Using a bivariate GARCH model, we examine patterns of information flows for three commodity futures traded in both the developed U.S. market and the emerging China market (copper, soybeans and wheat). For copper and soybeans, the two commodities that are subject to less government regulation and fewer import restrictions in China, we find that the U.S. futures market plays a dominant role in transmitting information to the Chinese market, a result that confirms the importance of the U.S. role as a leader in the global financial market. For the heavily regulated and subsidized wheat commodity, our empirical results indicate that the U.S.-China futures markets are highly segmented in pricing, although information transmission via volatility spillover across markets is present.     

The Effect of Futures Market Volume on Spot Market Volatility

There has been considerable interest, both academic and regulatory, in the hypothesis that the higher is the volume in the futures market, the greater is the destabilizing effect on the stock market. We show that conventional approaches, such as adding exogenous variables to GARCH models, may lead to false inferences in tests of this question. Using a stochastic volatility model, we show that, contrary to regulatory concern and the results of other papers, contemporaneous informationless futures market trading has no significant effect on spot market volatility.     

Onshore and offshore market for Indian rupee: recent evidence on volatility and shock spillover

The article empirically examines the onshor-offshore linkages of the Indian rupee using recently developed multivariate GARCH technique. The empirical results show that the offshore non-deliverable forward market does not have mean spillover impact on onshore spot, forward and futures markets while shocks and volatilities in the non-deliverable forward market influence the onshore markets. A key finding of the study is that the magnitude of volatility spillover from non-deliverable forward to spot market has accentuated after the introduction of currency futures in India. This development could be attributable to large arbitrage between futures and non-deliverable forward market in the more recent period. The finding has critical implications for exchange rate policy and management in the Indian context. There is need for close monitoring of both the onshore and offshore markets.     

Shock and Volatility Transmission in the Futures and Spot Markets: Evidence from Turkish Markets

This paper examines the volatility transmission mechanism between the futures and corresponding underlying asset spot markets, focusing on Turkish currency and stock index futures traded on the lately established Turkish Derivatives Exchange (TURKDEX). Employing multivariate generalized autoregressive conditional heteroskedasticity modeling, which allows for potential spillovers and asymmetries in the variance-covariance structure for the market returns, the paper investigates the volatility interactions among each of the three futures-spot market systems. For all market systems under study, the volatility spillovers are found to be important and bidirectional. For the stock index market system, in line with the previous literature, volatility shows asymmetric behavior and strong asymmetric shock transmission. The main implication is that investors need to account for volatility spillovers and asymmetries among the futures and the spot markets to correctly build hedging strategies.     

Volatility Transmission in the Real Estate Spot and Forward Markets

How shocks in one market influence the returns and volatility of other markets has been an important question for portfolio managers. In the finance literature, many studies found evidence of volatility spillovers across international markets, as well as between spot and futures markets. Although real estate is often regarded as a good vehicle for diversification, the dynamics of its volatility transmission have been largely ignored. This paper provides the first study to examine volatility spillovers between the spot and forward (pre-sale) index returns of the Hong Kong real estate market through a bivariate GARCH model. Transaction-based indices were used so that our volatility modelling was free from any smoothing problem. Our results showed that real estate returns exhibited volatility clustering, and the volatility of the forward market was more sensitive to shocks than the spot market. Moreover, volatility was mainly transmitted from the forward market to the spot market, but not vice versa.

股指期货与股票现货市场竞争关系研究——来自中国的经验证据

本文利用模拟生态学中种群间动态关系的Lotka-Volterra模型,对沪深300股指期货同股票现货市场在交易规模方面的竞争关系进行实证分析。研究结果表明,沪深300股指期货推出初期,股指期货市场与股票现货市场在交易规模方面存在竞争性的交易转移效应;随着股指期货市场相关规则的不断健全和完善,股指期货市场与股票现货市场在交易规模方面由竞争关系转变为共存关系,出现交易引资效应。同时,研究还发现,股指期货市场与股票现货市场之间关系由竞争性转变为共存性的重要原因是股指期货市场监管力度的加大,股指期货市场投资者结构的优化,以及股指期货市场期现套利交易的盛行。     

Transmission of Stock Returns and Volatility between the U.S. and Japan: Evidence from the Stock Index Futures Markets

In this paper, we examine the nature of transmission of stock returns and volatility between the U.S. and Japanese stock markets using futures prices on the S&P 500 and Nikkei 225 stock indexes. We use stock index futures prices to mitigate the stale quote problem found in the spot index prices and to obtain more robust results. By employing a two-step GARCH approach, we find that there are unidirectional contemporaneous return and volatility spillovers from the U.S. to Japan. Furthermore, the U.S.'s influence on Japan in returns is approximately four times as large as the other way around. Finally, our results show no significant lagged spillover effects in both returns and volatility from the Osaka market to the Chicago market, while a significant lagged volatility spillover is observed from the U.S. to Japan.
