Assessing time-varying stock market integration in Economic and Monetary Union for normal and crisis periods

In this paper, we examine the stock market integration process amongst 17 Economic and Monetary Union (EMU) countries from January 2002 to June 2013 over a normal period as well as for the Global Financial Crisis (GFC) and Eurozone Debt Crisis (EDC) periods. We classify the economies in three groups (A, B and C) based on their GDP to examine whether the economic size influences financial integration. Seven indicators are used for the purpose, namely, beta convergence, sigma convergence, variance ratio, asymmetric DCC, dynamic cointegration, market synchronisation measure and common components approach. The results suggest that large-sized EMU economies (termed as Group A) exhibit strong stock market integration. Moderate integration is observed for middle-sized EMU economies with old membership (termed as Group B). Small-sized economies (termed as Group C) economies seemed to be least integrated within the EMU stock market system. The findings further suggest presence of contagion effects as one moves from normal to crisis periods, which are specifically stronger for more integrated economies of Group A. We recommend institutional, regulatory and other policy reforms for Group B and especially Group C to achieve higher level of integration.

The EMU effects on asset market holdings and the recent financial crisis

This paper examines if there are significant integration effects from the establishment of European Monetary Union (EMU) and the introduction of euro on EMU and non-EMU equity and bond markets. This is done by looking at the holdings of these markets. We investigate to what extent these effects have been affected by the recent global financial crisis. This is done based on gravity model determining bilateral asset holding among the EMU countries, non-EMU European countries and the rest of world. This model can control for the effects of other economic (gravity-type) variables on the effects of the EMU on financial markets, like the size of the capital markets across countries, the geographical distance, information asymmetries etc. Ignoring these effects may exaggerate the actual EMU integration effects. The paper provides clear cut evidence that the establishment of the EMU had significant integration effects on equity and bond markets. It significantly increased the EMU bond and equity holdings by the EMU and non-EMU investors. These effects have become important since year 2001. However, they have considerably reduced after year 2007, due to the recent global financial crisis. Across the EMU countries, we have found that the strongest disintegration effects of the above crisis were observed for the peripheral countries of the EMU. These effects became evident before the start of the European debt crisis in early 2010.     

银行宏观审慎监管框架下的压力测试应用研究

国外对于银行体系宏观压力测试的研究已较为系统,全球金融危机进一步凸显了压力测试对于银行体系宏观审慎监管的重要作用。为加强银行的宏观审慎监管,增强金融稳健性,美国和欧盟相继开展了银行体系的压力测试工作,在压力测试范围、压力情景设置、测试方法等方面积累了一定的经验。对比我国商业银行体系压力测试情况,我国应从加强应用研究、完善银行体系宏观审慎监管数据库、提高压力测试效率和透明度、强化测试结果应用等方面改进压力测试工作。     

影子银行体系监管改革的国际经验及其对中国的启示

全球金融危机过后,影子银行体系的监管改革问题前所未有地成为各国金融当局普遍关注的热点,以美国为代表的发达经济体掀起了一场旨在规范影子银行体系发展的金融监管体制改革。本文的研究表明,过度金融创新以及金融监管的缺失是刺激美国影子银行体系迅速发展的直接原因。然而,危机过后,美国并未简单地采取抑制金融创新的办法加强对影子银行体系的监管,而是通过金融监管机构改革以及提高微观金融数据的采集与分析的办法,规范和引导影子银行体系的健康发展。这种市场化的监管改革思路值得我们借鉴。从影子银行体系的运行机制以及发展来看,中国的影子银行体系与美国存在较大差异,但全面强化宏观审慎金融监管是我国金融监管体制改革的大势所趋。在此情况下,美国金融监管改革的经验值得我们认真总结和研究。最后,本文认为,中国应当继续深化金融体制改革;积极探索现行金融监管框架的改革;加强微观金融数据的收集与整合,完善宏观金融风险预警机制。     

宏观审慎视角下的系统性金融风险研究

全球金融危机使监管者认识到仅靠微观审慎监管无法保证金融系统的稳定,必须加强逆周期的宏观审慎监管。本文首先回顾了对系统性金融风险、宏观审慎监管等重要概念的认识和发展;其次比较了美国、欧盟的逆周期宏观审慎政策框架;再次对我国的信贷投放、资本监管和贷款损失拨备的顺周期性进行了实证检验;最后,本文对我国的逆周期宏观审慎监管提出了相关建议。

Capital Market Integration in the Middle East and North Africa

This paper studies capital market integration in Middle Eastern and North African (MENA) countries and its implications for international portfolio investment allocation. Starting with four cointegration methodologies, we significantly reject the hypothesis of a stable, long-run bivariate relationship between each of these markets and the European Monetary Union (EMU), the United States, and a regional benchmark. This indicates the existence of significant diversification opportunities for three categories of investors (EMU, world, and regional investors). A recursive analysis based on Barari (2004) suggests that recently, the MENA markets have started to move toward international financial integration. Investigating the effect of selected financial, economic, and political events on such a process, we extend the methodology and find that the markets react heterogeneously to the different categories of shocks. They should therefore not be treated as a bloc for global allocation purposes. Finally, after adjusting the integration levels by relative market capitalization, Israel and Turkey are the most promising markets in the region, followed by Egypt, Jordan, and Morocco. Tunisia and Lebanon seem to be lagging behind.     

Does sovereign risk matter? New evidence from eurozone corporate bond ratings and zero-volatility spreads

In this paper, we empirically examine if sovereign risk matters for corporate bonds in developed economies. Using a unique panel data sample of 897 corporate bonds from eleven countries within the Economic and Monetary Union (EMU), we investigate sovereign and corporate ratings as well as zero-volatility spreads (z-spreads). In the time period from March 2006 to June 2012, we find sovereign risk to be a significant driver of corporate risk. The effect is stronger for companies with domestic revenue structure, for companies that are (partly) owned by the government, and companies active in the utility and transportation sector. Interestingly, the impact of sovereign risk on corporate risk during the acute European sovereign debt crisis period decreases if ratings are examined, but increases if z-spreads are utilized. Rating agencies seem to take a more differentiated view on individual company risk during the sovereign debt crisis, while institutional investors might want to reduce their exposure to a country in financial distress as a whole, regardless of whether sovereign or corporate bonds are held.     

Are global shocks leading indicators of currency crisis in Viet Nam?

This paper aims to identify leading indicators of a currency crisis in Viet Nam based on an early warning system for the period 1996–February 2016. This paper found that global financial shocks (e.g., regional and global financial crisis, unexpected changes in monetary policy of largest economies such as the United States and the People’s Republic of China), and domestic credit growth rate are leading indicators of a currency crisis in Viet Nam in all three models. Deficits in trade balance, international reserves, and overvaluation of the dong are also good indicators. In addition, a model in which a currency crisis or turbulence in the foreign exchange market is defined based on the exchange market pressure and parallel market premium, with window length of 2 months, outperformed for predicting a currency crisis in Viet Nam. Empirical results suggested that probability of predicting a true currency crisis was 77.5%.     

Returns and volatility spillover in the European banking industry during global financial crisis: Flight to perceived quality or contagion?

This paper empirically investigates return, volatility and leverage spillover effects between banking industrial stock markets of the major economies (ME) (Germany, UK and US) and the smaller stressed European Union countries (SE), (Italy, Ireland, Greece, Spain and Portugal) from 2002 to 2014 which includes the global financial crisis period (2007–2014). Thus the paper investigates the influence of the global crisis on the spillover between the banking industrial stock markets of Europe and the US. We apply a multivariate GARCH–GJR framework to investigate the effects of the financial crisis with respect to spillover. Our results indicate an increase in both means and volatility spillover between the major economies and the stressed EU economies from the pre-crisis to the crisis period. During the pre-crisis period there is ample evidence of spillover from Germany, UK and the US to the smaller EU economies. Little evidence of a significant spillover from the smaller economies to the major economies is found during this period. We find that return and volatility transmission mechanisms between the major economies and the smaller EU countries are asymmetric during the crisis period. During the crisis, the level and amount of spillover from the major economies increase. But now there is also clear evidence of spillover from smaller EU economies to the major economies, this is especially true for Germany and the UK. Evidence of spillover effects suggests the existence of exploitable trading strategies and has important implications to investors in the areas of option pricing, portfolio optimization and risk management.     

Weathering the crisis and beyond: perspectives for the Euro area

The Euro area is experiencing a severe and highly complex crisis. It comprises three problem areas: the difficulties of some highly indebted European sovereigns to ascertain funding at palatable cost, the disconcerting fragility of the European banking system and disappointing growth prospects in the Euro area periphery. To make matters even worse, these problems have developed into a systemic crisis of the European Monetary Union (EMU), since observers have apparently developed fundamental doubts over its integrity. To overcome this systemic crisis, it would not be sufficient, if only the stronger Euro area economies provided more solidarity, nor would it be sufficient, if only all of Europe adhered to ironclad budgetary discipline from now on. A European Redemption Pact could be a strong political commitment to the EMU and offer a bridge between the proponents of fiscal discipline and structural reform and those governments advocating more support. This pact would entail two indispensable aspects, the codification of a credible and coherent reform path and a temporary and limited instrument for joint refinancing.     

The impact of distressed economies on the EU sovereign market

Financially distressed economies inside the European Union (EU) are being blamed for producing a general increase in borrowing costs. This article analyzes the channels of default risk transmission within the EU countries using the information content in the sovereign Credit Default Swap (CDS) market. We proceed in two directions. First, we test the existence of cross-border volatility effects between the central and the peripheral EU countries. Second, we explore the effect of distressed economies on the default and risk premium constituents of sovereign default swaps. We show a significant volatility spillover from distressed to central European Economic and Monetary Union (EMU) economies. This causality pattern leads to a significant impact on the default swap risk premia. On average, the risk premium accounts for approximately 42% of central EMU spreads and 56% of the spreads for those countries outside of the EMU. The peripheral risk also affects the default component of central economies, although its impact is lower.     

Unraveling the Financial Contagion in European Stock Markets During Financial Crises: Multi-Timescale Analysis

The article investigates the evidence of financial contagion and market integration in selected European equity markets during nine major crises across regions. The focus is to identify whether (i) contagion evidence is pure or fundamental and (ii) dynamic evolution of integration is in the short run or long run. Wavelet decomposition in both its discrete and continuous forms is used. The findings reveal the following: (i) prior to the subprime crisis, contagion effects generated short-term shocks. The most recent US subprime crisis, however, reveals the evidence of fundamental based contagion. (ii) We find increasing short-run and long-run stock market integration, driven by several stages of the establishment of Economic and Monetary Union (EMU), questioning the ultimate benefits of formal entry into EMU membership.     

Bidder returns in bancassurance mergers: Is there evidence of synergy?

We provide evidence on the potential for bidder wealth gains in bancassurance mergers by examining a sample of such mergers in the United States and abroad. These combinations are expected to produce positive wealth gains if there are synergies between these two types of financial firms. We find positive bidder wealth effects that are significantly related to economies of scale (as measured by the size of the target relative to the bidder), potential economies of scope, and the locations of the bidders and targets. These results suggest that the bancassurance architectural structure for financial firms does offer some benefits and thus may become more prominent in future years.     

国际金融视角下美国两次金融危机的比较及对中国的启示

随着金融危机的不断深化,国际金融形势的变化越来越引人注目,金融危机背景下的中国经济也面临着巨大考验。本文从虚拟经济与实体经济的关系、国际短期资本流动、国际间政策协调三个方面对美国历史上两次世界性金融危机的情况进行比较分析,得出相应结论及对我国的启示。     

Financial Integration and EMU

This paper investigates the effect of European Monetary Union on the integration of the financial services industry within European using data on the announcements of M&A's within the industry. We find some evidence that EMU has helped financial integration within the euro area. In addition, financial institutions in EMU countries became more active in initiating integration between EMU and non‐EMU partners, which also contributed to overall regional integration within European. The more active role of EMU institutions suggests that institutions residing in the eurozone became stronger players in the corporate control market. However, EMU does not facilitate the entry of non‐European institutions into European.
