人民币在岸市场已经是一个 非完全定价中心*

本文的研究结果表明在岸市场依然具有人民币汇率定价中心的性质,主要体现在在岸即期和远期汇率都会对离岸远期汇率的变动有显著的均值溢出效应。而离岸即期市场对在岸即期市场存在较小幅度的均值溢出效应以及三大市场之间已经存在着一定波动和冲击溢出效应,则表明在岸市场已经不是一个完全定价中心。从溢出效应的程度和传递方向来看,稳定在岸人民币汇率定价预期仍然是降低汇率过度波动的关键。     

基于格兰杰和GARCH模型对人民币即期与远期引导关系的研究

采用格兰杰分析方法对2011年6月27日至2013年12月31日期间共919对人民币兑美元境内远期、香港离岸远期对境内即期汇率的引导作用进行研究,结果表明,境内远期市场和香港离岸市场的部分远期汇率对境内即期汇率有引导作用。其次使用GARCH模型检验,两个远期市场对境内即期汇率都有一定的溢出效应,且期限越小的远期汇率溢出效应越明显,香港离岸市场比境内远期市场溢出效应更明显。     

An empirical examination of factors driving the offshore renminbi market

Following the 2010 establishment of the offshore renminbi market in Hong Kong, renminbi deposits there quickly rose above RMB 1 trillion. In this article, we examine fluctuations between the offshore value of the renminbi in Hong Kong and its onshore value in mainland China. The size of the spot market spread appears to be influenced by stock market sentiment as reflected in the spread between A-shares listed in Shanghai and H-shares listed in Hong Kong. There is also some evidence of a link between the spread and the pace of renminbi deposit growth in Hong Kong.     

Return and volatility spillovers effects: Evaluating the impact of Shanghai-Hong Kong Stock Connect

This study investigates the impact of the recently introduced Shanghai-Hong Kong Stock Connect. Using high frequency data and dynamic forecasting techniques, we find that the new Stock Connect does contribute to the increasing importance of the Chinese mainland stock market and economic activity. A weak and unstable cointegration relationship is found after this event. Additionally, the Stock Connect has also increased the conditional variance of both stock markets. We observe a leading role of the Shanghai stock market to the Hong Kong stock market in terms of both mean and volatility spillover effects after the Stock Connect. Our study indicates that the opening up of stock markets in China could enhance the leading power, influence the risk level and improve the market efficiency of the Chinese mainland stock market, since the volatility spillover effect from Shanghai to Hong Kong is strengthened. Besides, our results have important policy implications, especially on how policy makers should deal with the increased market interconnectedness and for portfolio managers in choosing potential hedging instruments. The success of Shanghai-Hong Kong Stock Connect provides valuable operational experience for the forthcoming Shenzhen-Hong Kong Stock Connect which could further improve the market efficiency in China.

Asymmetric spillover effects between the Shanghai and Hong Kong stock markets: evidence from quantile lagged regression

This article surveys the asymmetric spillover effects between the mainland China-based Shanghai Composite Index (SCI) and the Hong Kong based Hang Seng Index (HSI) using a quantile lagged regression model. Compared to previous studies, this article, based on data before and after the 2008 global financial crisis, presents a more detailed analysis, as we investigate the spillovers in terms of returns, volatilities and exchange rates between the renminbi (RMB) and the Hong Kong dollar (HKD) throughout the entire conditional return distribution, including the central quantiles, which are closely related to the normal circumstances, and the extreme quantiles, which correspond to the bear and bull markets. First, we find that the return spillovers from its lagged returns or from the other index not only vary across time but also depend on stock state. Second, while return volatility may boost the stock market in a bull market, it accelerates the decline in a bear market. Third, the depreciation of the RMB relative to the HKD does not significantly affect current returns for the HSI, while it negatively affects current returns for the SCI in a bad state after the crisis. The findings presented in this article will facilitate investors’ understanding of the two stock markets.     

人民币NDF与即期汇率的动态关联性研究

文章以2005年7月25日~2006年6月13日间人民币NDF和即期汇率为研究对象,以MA(1)-GARCH(1,1)模型分析人民币NDF市场和即期市场间均值和波动的溢出效应。分析结果表明,两个市场的波动没有相互溢出效应,即期市场对人民币NDF市场没有报酬溢出效应,而人民币NDF市场对即期市场具有报酬溢出效应。可见,我国汇制改革后,境外因素已开始影响人民币即期市场。     

人民币汇率定价的逆周期因子：启用时间、驱动因素与实施效果*

本文对2017年5月—2019年9月期间人民币汇率定价过程中逆周期因子的使用进行了测算，并构建非限制性VAR模型分析了中国央行两次启用逆周期因子的驱动因素和实施效果。研究发现：第一，相对于官方公布时间，两次逆周期因子调节均呈现出提前开始和滞后结束的情况，且调整幅度呈现逐渐收窄的趋势；第二，第二次逆周期因子的调节幅度大于第一次；第三，人民币汇率波动是第一次逆周期因子调节的主要驱动因素，而离岸在岸汇价差和汇率政策不确定性是第二次逆周期因子调节的主要驱动因素；第四，两次逆周期因子调节均对人民币汇率波动产生了抑制作用，但加剧了离岸市场人民币贬值预期。

人民币即期汇率与NDF汇率关系的实证分析

以人民币即期汇率与NDF汇率为例研究境内市场与境外市场的信息传递。主要利用GARCH模型描述人民币即期汇率与NDF的变动并检验人民币即期汇率与NDF之间的均值溢出效应和波动溢出效应。得到的主要结论为,人民币NDF市场对人民币即期汇率市场有均值溢出效应,人民币即期汇率和NDF之间有双向波动溢出效应。这表明信息流由境外市场传导至境内市场,人民币即期汇率市场受到境外市场因素的影响,境外人民币NDF市场是境内即期市场的先导。     

人民币汇率改革评析

本文对近20年来人民币汇率改革的实际成效进行评价，笔者认为改革配套措施的短视化倾向制约了汇率市场化改革目标的实现程度。除了参考IMF事实汇率分类法的外部评价，本文以高度市场化的香港离岸人民币汇率作为参考指标，通过定量分析证明境内人民币即期汇率中间价的市场化程度低于收盘价。本文最后强调，深化汇率改革的关键在于完善汇率形成的市场基础以及淡化中央银行汇率责任。

Financial contagion and volatility spillover: An exploration into Indian commodity derivative market

This study measures the extent of financial contagion in the Indian asset markets. In specific it shows the contagion in Indian commodity derivative market vis-à-vis bond, foreign exchange, gold, and stock markets. Subsequently, directional volatility spillover among these asset markets, have been examined. Applying DCC-MGARCH method on daily return of commodity future price index and other asset markets for the period 2006–16, time varying correlation between commodity and other assets are estimated. The degree of financial contagion in commodity derivative market is found to be the largest with stock market and least with the gold market. A generalized VAR based volatility spillover estimation shows that commodity and stock markets are net transmitters of volatility while bond, foreign exchange and gold markets are the net receivers of volatility. Volatility is transmitted to commodity market only from the stock market. Such volatility spillover is found to have time varying nature, showing higher volatility spillover during the Global Financial Crisis and during the period of large rupee depreciation in 2013–14. These results have significant implication for optimal portfolio choice.     

NDF监管政策对境内外人民币远期市场联动效应的影响研究

研究境内外人民币远期市场间的联动效应,对发展和监管人民币衍生市场控制风险具有重要意义。本文实证检验了境内外人民币远期市场之间的联动效应,发现在禁止境内机构参与离岸人民币无本金交割远期(NDF)的通知颁布后,3个月期人民币境内本金交割远期(DF)汇率不再是3个月人民币NDF汇率的Granger原因,而3个月的NDF汇率依然引导3个月的DF汇率。本文分析了这一NDF监管政策对境内外人民币远期价格间相互关系的影响以及内在原因。     

人民币即期汇率与境内外远期汇率动态关联——NDF监管政策出台之后

文章运用Granger因果检验方法和DCC-MGARCH模型,对外管局禁止境内机构从事NDF交易后人民币对美元即期汇率市场、境内远期汇率市场和境外NDF市场之间的动态关联关系进行了实证研究,研究发现:市场间常条件和动态条件相关系数随着合约期限的增长呈递减态势,即期市场与NDF市场之间的相关性最强,境内外远期市场之间的相关性最弱;虽然即期市场存在对NDF市场的信息波动溢出效应,但从总体上看,NDF市场的价格引导力量强于即期市场和境内远期市场,处于市场价格信息的中心地位。     

An analysis of the spillover effects of exchange-traded funds

This article used the Generalized Autoregressive Conditional Heteroscedasticity-Autoregressive Moving Average (GARCH-ARMA) and the exponentially Generalized Autoregressive Conditional Heteroscedasticity-Autoregressive Moving Average (EGARCH-ARMA) models to study the impact of the spillover and the leverage effects on returns and volatilities of stock index and Exchange Trade Fund (ETF) for developed and emerging markets. Previous unexpected returns for developed and emerging markets which have an opposite influence pattern on ETFs’ returns were identified. The spillover effects from returns are excellent for Hong Kong, followed by Singapore. Meanwhile, Taiwan's stock index return was recorded to have a strong negative impact on ETF return. Notably, this article shows that the spillover effects on stock index and ETF volatilities existed with bilateral influences. Despite a strong positive asymmetric volatility effect in Korea's ETF market, the leverage effect appears to play important roles in the explanation of both stock index and ETF returns.     

Wealth,volume and stock market volatility: case of Hong Kong (1993–2001)

This article attempts to answer the question of whether the gain and loss in property market speculations and rate of information flow play a significant role in stock market volatility in Hong Kong. To test for our wealth–volume–volatility hypothesis, two different measures of volatility: absolute (absolute value of SD from mean with monthly dimension) and conditional (EGARCH) are used and results are compared. In both measures, we find evidence of a statistical presence of a wealth effect on stock market volatility, particularly in the investment of luxury class of property in Hong Kong. To account for this result, we apply the prospect theory, house money effect and the newly developed conditional confidence theory. Although we fail to establish a volume–volatility relationship in our estimation, we offer additional dimensions to the explanation of our observation.     

人民币区域接受程度： 指数构建与影响因子计量 ——以东盟及中国香港为例

金融危机以来,改革现有的国际货币体系,逐步推进“去美元化”进程,已是国际社会共识。周边化及区域化是人民币国际化进程中的重要阶段,建立人民币区域接受程度监测指标体系,具有重要意义。本文基于对东盟及中国香港人民币使用情况的分析,提出人民币区域接受程度指数的构建框架并进行影响因子的计量分析,实证结果表明：(1)在政策推动及市场需求双重作用下,未来东盟人民币接受程度将持续提升,但短期内受经济政治影响会出现较大反复;(2)受政策推动、存款规模较小以及贬值预期影响,中国香港人民币贸易接受程度的提升快于金融接受程度,提高人民币存款占比有助于提升人民币接受程度;(3)中国香港经济状况对人民币接受程度的影响力要高于内地,反映出货币国际化是市场自发选择的过程;(4)由于货币替代影响双边货币政策效果,中国香港通胀水平、利率以及内地通胀水平会受中国香港人民币接受程度的反向影响。
