Spillover Effect in the RMB Foreign Exchange Market: Based on VAR and DCC-MVGARCH Models

This paper analyzes the stability and marketization of the RMB exchange rate after China introduced the foreign exchange rate reform by linking the RMB exchange rate with the offshore and onshore markets on August 11, 2015 (“8/11”). Under the framework of dynamic analysis, through Granger causality test, VAR model and DCC-MVGARCH model, the empirical analysis is conducted about the three market exchange rate linkages of CNY, NDF and CNH from May 2012 to December 2018. Then, the direction and degree of the linkage between the RMB's offshore and onshore exchange rates before and after the“8/11” exchange rate reform are compared. The research results show that: (1) since the “8/11”exchange rate reform, the RMB exchange rate has become more flexible; (2) the price-determining power of the RMB exchange rate may be weakened, and policy adjustment should take effect; and (3) the prerequisites, under which the offshore market can play a role, are the development of the market itself. This paper proposes that: (1) the onshore and offshore markets should develop in a collaborative manner to further increase exchange rate elasticity and flexibility; (2) close attention should be paid to the relationship between the offshore and onshore markets, and policy determination and flexibility should be maintained; and (3) the offshore market should be improved and play a due role.     

人民币汇率价格信息传导机制研究 ——基于离岸和在岸即期市场的实证分析

随着人民币国际化进程的不断推进,离岸与在岸的人民币即期汇率市场之间开始有均值(或波动)的相互影响。该价格信息传导机制具体表现为:两个市场之间存在均值和波动溢出效应,并且均值溢出效应不太稳定,波动溢出效应相对稳定;内部因素的变化往往会改变价格信息传导的方向和作用,而外生冲击的影响则相对有限;当期升值较快的市场往往会主导均值溢出效应,但波动溢出效应是由受政策预期影响的在岸市场所主导;利好消息会减少离岸市场的波动,但会加大在岸市场的波动。     

中国货币政策不确定性和宏观经济新闻的人民币汇率效应

基于2012年4月30日至2018年12月17日的银行间7天逆回购操作利率,本文首次使用波动率回归拟合的方法,从政策利率的角度改进中国货币政策不确定性指数,并进一步研究了在不同程度货币政策不确定性的情况下,人民币兑美元汇率对宏观经济新闻的反应。收集和构建10项宏观经济新闻后,本文发现当市场参与者普遍不能较为准确地预测未来政策变化的情形时,货币政策不确定性上升,在岸、离岸人民币兑美元汇率对宏观经济新闻的反应显著减弱。当货币政策存在较高不确定性时,市场对未来政策判断的分歧加剧,进而人民币汇率对宏观经济新闻的反应不足。在货币政策不确定性较高时,增加央行的汇率沟通,可以发挥其对宏观经济新闻的补充作用,同时增强市场对宏观经济基本面信息的反应。本文不仅丰富了货币政策不确定性的负面影响、经济后果以及宏观经济新闻的人民币汇率效应相关理论研究,而且为未来货币政策制定、调整和实施提供了有价值的依据,为货币当局进行有效外汇市场干预提供了经验参考。     

“一带一路”中的人民币国际化:进展、问题与可行路径

随着"一带一路"建设的推进,人民币国际化迎来了新的发展机遇。目前,"一带一路"沿线人民币跨境结算稳步推进,中国与"一带一路"沿线国家的货币互换合作不断加深,"一带一路"沿线国家人民币国际化的金融基础设施逐渐完善,在"一带一路"沿线国家人民币计价功能初步发展。但人民币国际化在"一带一路"沿线仍存在许多问题,表现为人民币在"一带一路"沿线跨境使用与贸易需求不匹配,人民币国际化在"一带一路"沿线的地区发展不平衡以及功能发展不协调。为了推动"一带一路"沿线人民币国际化进程,应充分挖掘"一带一路"沿线人民币的真实需求,重点发挥人民币在投融资活动中的作用;以大宗商品为突破点,推动人民币计价功能提升;加强金融基础设施建设,完善人民币回流机制,推动"在岸—离岸"市场的良性互动。     

The Price Discovery Puzzle in Offshore Yuan Trading: Different Contributions for Different Contracts

The People's Bank of China (PBC) lifted yuan trading restrictions in July of 2010 that led to offshore yuan spot trading in Hong Kong. Based on causality analyses, we find that price discovery is absent between the onshore and offshore spot markets. However, we document the presence of price discovery between onshore spot and offshore nondeliverable forward (NDF) rates. These seemingly inconsistent results present a puzzle wherein one offshore market appears to be more informationally integrated with the onshore market than another. We conclude that price discovery differences in the offshore markets stem from the offshore spot and forward contracts tracking different aspects of yuan rates (e.g., the offshore nondeliverable rate tracks onshore spot rates whereas the offshore spot rate tracks onshore interest rates). Moreover, the introduction of offshore spot trading in Hong Kong has led to an increase in cross‐market price discovery between onshore spot and offshore NDF rates. © 2012 Wiley Periodicals, Inc.

人民币跨境流动自由度的测算——基于资本项目名义开放指数的借鉴

长期以来,人们只看重货币国际化结果,以占全球贸易计价结算比重、外汇交易比重、国际债券比重、外汇储备比重等相关指标衡量一国货币的国际化程度,而忽视货币跨境流动放松过程,即一国货币的跨境流动自由化程度。货币国际化是一个过程又是一种结果,包含进程和结果两个层面,在货币国际化进程中,过早过快放松本币流出入会引发经济金融风险,某些情形下进程比结果更值得关注。构建人民币跨境自由度指数涉及强度赋值、项目设置和权重确定三方面内容。在梳理2019年第2季度前我国货币政策基础上,对2008年至2019年经常项目下的人民币跨境流动自由度、证券投资项目下的人民币跨境流动自由度以及资本项目下的人民币跨境流动自由度进行评估,并以美国近5年各项目下的资金流动平均占比为权重,构建了人民币跨境流动自由化指数,考察2008—2019年人民币跨境流动自由化程度,结果显示人民币国际化进展较快,跨境流动已得到很大程度放松,而且人民币流入自由程度显著高于流出自由度。我国人民币国际化进程应持续遵循先经常项目后资本项目、先流入后流出、先机构后个人、先大额后小额、先风险小项目后风险大项目的次序,提高人民币跨境流动的稳定性,降低无序流动的投机风险;严格管控证券投资、其他投资、衍生品项目下人民币跨境流动,并依据我国利率市场化程度、金融市场发达程度及审慎监管能力进行调整;大力提升经常项目的人民币结算比重,发展人民币离岸市场,提高非居民间的人民币使用频率和使用规模;充分评估各项目下人民币跨境流动和本外币兑换自由度,提高两者的协同匹配程度,降低因两者不匹配而产生的负面影响。     

Dynamic linkage between the Chinese and global stock markets: A normal mixture approach

The paper provides an empirical framework for analyzing the dynamic linkage between Chinese and thirty major stock markets globally. In doing so, we employ the bivariate normal mixture model, a weighted average of two normal distributions that can reveal both the degree and structure of dependence between markets. We show that the level of dependence strengthened since 2004 in general, whereas the contagion effects spread heterogeneously during the global financial crisis. We also examine potential factors that affect the stability of the linkage by capturing regime switching behavior. The results suggest that business cycle synchrony plays a significant role in increasing the instability of dependence between the Chinese and global stock markets, while the impact of asynchrony is negligible. Additionally, we observe increased dependence and unstable structure, associated with the implementation of China's capital market liberalization policies and RMB exchange rate reform.     

人民币汇率与中国的货币控制

本文以近期掀起的又一轮呼吁人民币升值的讨论为背景,再次对人民币汇率以及中国货币控制进行分析。通过分析因人民币升值而引起的中国所面临的货币困境,以及解决困境所采取的措施(即建立CIC和对流动性的对冲操作),评论了措施的局限性,并从汇率的利率平价理论入手分析人民币汇率与中国货币控制的互动关系;借鉴日本经验分析并佐证了关于汇率的几个错误概念,提出近期应去除人民币单向升值的预期,只有保持汇率相对稳定才有利于中国经济发展。     

人民币区域化与国际化问题探讨

从目前中国现实的经济情况看,人民币国际化的时机尚未成熟,只能是一个循序渐进的长期发展过程。但人民币区域化是我国在近期可确立的较确实可行的目标。为推进人民币国际化,中国经济必须要保持在亚洲的领先增长,保持人民币币值稳定。要发展金融市场,消除金融隐患。加强与亚洲国家的贸易往来和直接投资,加快人民币的自由兑换,为人民币最终走向国际化做好必要的准备。     

人民币汇率购买力平价假说的实证检验

从长期来看,购买力平价对人民币汇率虽然具有一定的解释作用,但有很大的局限性。汇率的变动不仅仅与物价水平相关,还与一国的生产力发展水平、利率、资本流动等其他经济变量以及该国施行的货币政策、财政政策和汇率政策有关。因此,必须对购买力平价计量检验模型进行修正,以期更好地解释人民币汇率的变化并指导其调整。     

International spillovers of China's structural reforms

This paper sheds light on the international spillovers of China's reforms in upgrading industrial capabilities, liberalizing capital account, internationalizing the renminbi, and transition to flexible exchange rates. Drawing on two-country New Keynesian model of endogenous entry and portfolio adjustment, we find that China's industrial upgrading that peddles on yuan appreciation lifts all boats through global production network irrespective of capital account convertibility, degree of renminbi internationalization, and exchange rate reform. Feasibility of appreciation-driven upgrading is called into question, however, when renminbi reform and capital account liberalization go in parallel. We also show that international spillovers disappear once renminbi internationalization is associated with liberalized capital account and flexible renminbi exchange rates.

人民币国际化的现实路径与机遇

随着中国经济的发展,国际影响力的提高,人民币的国际地位也随之提升,边境贸易助推人民币区域化,货币互换为增加境外人民币存量提供了制度安排,离岸中心为境外人民币提供了服务平台,人民币国际化在各个领域已经形成共识。受全球金融危机的影响,世界关键货币——美元持续疲软,国际能源价格持续下跌,给人民币国际化创造了难得的历史机遇,人民币加速国际化的呼声也越来越高涨。中国应利用人民币升值通道期,推动人民币国际结算功能实现;利用石油价格的下跌期,推动重要能源的人民币国际计价;利用中国全球贸易地位,树立人民币储备货币地位。     

人民币外汇市场压力指数变动及压力释放效果研究

根据汇率变动的压力来源,引入包括名义汇率、外汇储备、国际利差、通胀水平差、远期升贴水、双边贸易差额等在内的六个因素构建外汇市场压力指数,综合分析2000年1月至2008年6月人民币汇率变动的压力来源。结果显示:人民币的升值压力除了在汇改之初小幅下降外,在其他考察时间段内基本都表现出明显的升值趋势,且各个阶段的汇率走势和压力源贡献分解也体现出差异化的特点。     

人民币适度升值是我国经济可持续发展的需要

在现阶段我国市场机制还不完善条件下,人民币汇率变化主要取决于经济增长这一政策目标,但随着我国经济增长方式的转变,人民币汇率政策也应做相应调整,人民币适度升值有利于我国经济的可持续发展。     

Market integration and contagion: Evidence from Asian emerging stock and foreign exchange markets

This paper examines whether Asian emerging stock markets (India, Korea, Malaysia, Philippines, Taiwan, and Thailand) have become integrated into world capital markets since their official liberalization dates by estimating and testing a dynamic integrated international capital asset pricing model (ICAPM) in the absence of purchasing power parity (PPP) using an asymmetric multivariate GARCH(1,1)-in-Mean approach. Also examined in this paper is whether there are pure contagion effects between stock and foreign exchange markets for each Asian country during the 1997 Asian crisis. The empirical results show that first, both currency and world market risks are priced and time-varying, suggesting that an international asset pricing model under PPP and constant price of risk might give rise to model misspecification. Second, the stock markets for India, Korea, Malaysia, Philippines, and Thailand were segmented from the world capital markets before their liberalization dates, but all six markets have become fully integrated since then. Third, the market liberalization has reduced the cost of capital and price volatility for most of the countries. Finally, as for the contagion effects, strong positive impact of return shocks originating from the domestic stock market to its foreign exchange market during the crisis is found. This dynamic relationship between stock market and foreign exchange market is consistent with stock-oriented exchange rate models.     

人民币利率对汇率影响的实证研究：1981—2003

定量分析人民币利率对汇率长期走势与短期波动的影响,对于中国利率市场化与汇率制度选择等问题意义重大.对时间序列变量进行单位根检验、协整检验,以及建立误差修正模型等实证研究表明:无论在长期还是短期,人民币利率对汇率都是反向影响.长期内,利率对人民币汇率存在较强的影响;短期内,利率对人民币汇率影响较弱.我国利率主要还是通过商品市场间接地对汇率产生作用.     

China's exports,export tax rebates and exchange rate policy

This paper examines the relationship between China's exports, export tax rebates and exchange rate policy. It offers an explanation for why China's exports continued to rise under RMB real appreciations during the Asian financial crisis. Based on a traditional export demand model, we test our hypothesis that the counteracting effects of China's export tax rebate policy have diminished the effectiveness of real exchange rates in facilitating the resolution of trade imbalances under the current pegged exchange rate regime. We find evidence that RMB real appreciations during the crisis negatively affected China's exports, but the negative effects were mitigated by the positive effects of export tax rebates. We also find evidence of a long‐run relationship between China's exports and the other explanatory variables. The empirical evidence suggests that under the pegged exchange rate regime with limited adjustments, real exchange rate movements alone cannot resolve China's external imbalances. The policy implication of this study is that China needs to redirect its decades‐long export‐oriented development strategy to one that emphasises domestic demand‐oriented development and to replace the current pegged exchange rate regime with a market‐oriented more flexible exchange rate regime.     

建立和完善人民币离岸金融市场监管的思考

随着中国经济实力的增强,人民币离岸需求的日益扩大,人民币离岸金融中心的建设已是大势所趋。人民币离岸中心的建立虽然会给现存的金融制度带来一定的冲击和风险,但是只要监管得当,人民币离岸中心的建立将对我国金融业的改革发展起到良性的促进作用,也将进一步推动人民币国际化的进程。
