Dynamic stock market integration driven by the European Monetary Union: An empirical analysis

We examine the influence of the European Monetary Union (EMU) on the dynamic process of stock market integration over the period 2 January 1989–29 May 2003 using a bivariate EGARCH framework with time-varying conditional correlations. We find that there has been a clear regime shift in European stock market integration with the introduction of the EMU. The EMU has been necessary for stock market integration as unidirectional causality was found. Linear systems regression analysis shows that the increase in both regional and global stock market integration over this period was significantly driven in part, by macroeconomic convergence associated with the introduction of the EMU and financial development levels.     

Effects of Economic Convergence on Stock Market Returns in Major EMU Member Countries

This study updates and extends existing literature by investigating the effects of economic convergence among major European Economic and Monetary Union (EMU) member countries on stock market returns in each respective nation. Main findings include: (1) long-term stability in the EMU appears to be attainable, but further integration of product and factor markets is needed to reinforce convergence of real sectors; (2) the UK can be considered a quasi EMU participant due to convergence of its key economic variables with those of formal EMU members; and (3) economic convergence appears to be an important contributing factor to returns from stock markets in the included EMU countries except Germany.     

Time varying integration of European stock markets and monetary drivers

This study analyzes time-varying integration of stock markets among fourteen European countries and its monetary drivers relevant to the two contrasting events — the introduction of Euro in 1999 and banking crisis of GIIPS in 2011. Our panel analysis reports evidence that monetary performance convergence, lower differentials in interest rates and inflation among EU countries, has been a key driver for the increase in integration of EU stock markets post EMU. Our qualitative analysis indicates that post EMU, the GDP differences among the EU countries have reverse relations with monetary performance convergence. This finding is in line with those of our quantitative study with a price-based indicator for integration.     

Market Impact on financial market integration: Cross-quantilogram analysis of the global impact of the euro

We contribute to the literature by providing a more comprehensive understanding of the impact the euro has had on financial market integration with economies of different characteristics outside and within the European market via inclusion of market conditions influence on the level of financial integration. Our paper employs the recently developed cross-quantilogram (Han et al., 2016) approach to examine quantile dependence between the conditional stock return distributions of Germany and the UK with that of three common currency groups within EMU (Finland, France, and Italy), two global leading markets (the US and Japan), and two of the most promising emerging markets (China and India). We find three key results. First, both the EU membership and the common currency union affect the degree of financial market integration. Nevertheless, disentangling the effects of EU membership from the common currency shows that the common currency group has an additional impact on financial integration, as the degree of dependence is stronger in the common currency group than in the sovereign currency group and other groups. Second, there is a heterogeneous dependence structure, which is strongly observed for the UK and German stock returns with that of developed (the US and Japan) and emerging markets (India and China). Third, cross-quantile correlations change over time, especially in low and high quantiles, indicating that they are prone to jumps and discontinuities in the dependence structure. As far as we are aware, this is the first study in this field employing a cross-quantilogram method to examine the impact of different market conditions on the correlations, making our study a pioneer in the field of stock market integration.     

Stock market synchronization and monetary integration

This paper focuses on the relationship between stock market comovements and monetary integration. A panel specification is used to explain bilateral stock market return correlations between fifteen developed economies over the period 1975-2006. Time fixed effects are included to capture global shocks and we also examine the role of bilateral trade linkages and international financial integration. Monetary integration leads to stronger stock market synchronization, both through the elimination of exchange rate volatility and through the common monetary policy and the convergence of inflation expectations. Trade and financial integration also contribute to higher stock market return comovements.     

Integration of emerging stock markets with global stock markets

Financial integration for emerging economies should be seen as a long-term objective. In this paper, we examine stock market integration among five selected emerging stock markets (Brazil, China, Mexico, Russia and Turkey) and developed markets of the US, UK and Germany. The bounds testing approach to cointegration and error-correction modeling are used on monthly data from January 2001 to December 2014 to determine the short-run and long-run relationship between emerging stock market returns and the returns of the developed stock markets. The results show evidence of the existence of short-run integration among stock markets in emerging countries and the developed markets. However, the long-run coefficients for stock market returns in all emerging countries show a significant relationship only with Germany stock market return. The empirical findings in this study have important implications for academicians, international investors, and policymakers in emerging markets.     

Asian Economic Integration and Stock Market Comovement

Using daily returns from 1988 to 1998, we investigate to what degree twelve equity markets in Asia are integrated with Japan's equity market and examine the factors that affect the level of economic integration. We find that the equity markets of Australia, China, Hong Kong, Malaysia, New Zealand, and Singapore are highly integrated with the stock market in Japan. There is also evidence that these Asian markets become more integrated over time, especially since 1994. A higher import share as well as a greater differential in inflation rates, real interest rates, and gross domestic product growth rates have negative effects on stock market comovements between country pairs. Conversely, increased export share by Asian economies to Japan and greater foreign direct investment from Japan to other Asian economies contribute to greater comovement.     

Evolution of international stock and bond market integration: Influence of the European Monetary Union

This paper examines the dynamic relationship between daily stock and government bond returns of selected countries over the past decade to infer the state and progress of inter-financial market integration. We proceed to empirically investigate the influence of the European Monetary Union (EMU) on time variations in inter-stock–bond market integration/segmentation dynamics using a two-step procedure: First, we document the downward trends in time-varying conditional correlations between stock and bond market returns in European countries, Japan and the US. Second, we investigate the causality and determinants of this interdependent relationship, in particular, whether the various macroeconomic convergence criteria associated with the EMU have played a significant role. We find that real economic integration and the reduction in currency risk have generally had the desired effect on financial integration but monetary policy integration may have created uncertain investor sentiments on the economic future of the EMU, thereby stimulating a flight to quality phenomenon.     

An Investigation of Global and Regional Integration of ASEAN Economic Community Stock Market: Dynamic Risk Decomposition Approach

This article investigates the dynamic pattern of stock market relations between the ASEAN Economic Community (AEC) and two major stock markets: China and the United States. A GARCH risk decomposition model is developed to reflect the time-varying market integration. The primary findings of this study are as follows. First, the AEC is more integrated with the regional stock market than with the global stock market. Second, the movement in the AEC stock market is mainly driven by domestic economic situations. Third, external shocks only affect the level of integration of the AEC temporarily. Finally, international investors are able to significantly reduce unsystematic risk by adding an AEC market portfolio into their existing portfolios.     

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.     

Changing integration of EMU public property markets

This paper examines the impact of the European Monetary Union (EMU) on European public property market integration. Results indicate that the property markets are long-run independent and show little evidence of short-run relationships prior to the formation of the EMU. However, the degree of interdependence and the extent of convergence among the largest property markets have intensified substantially after the launch of the Euro as the common currency in January, 1999. Moreover, each of the property markets under consideration is endogenous in that none is found to “dominate” the others toward long-run equilibrium. Short-run results indicate substantial interrelationships among the markets after the adoption of the Euro. Finally, the study shows that stock markets, bond markets, and public property markets follow similar convergence patterns.     

Stock market integration in East and Southeast Asia: The role of global factors

This study explores the issue of financial integration among stock markets of ASEAN5 economies, plus China (mainland China and Hong Kong), Japan and South Korea (referred to as ASEAN5+4). Using both graph theory and a Vector Autoregressive (VAR)-based method, together with a rolling window approach, we show that the level of interconnectedness among these markets is high but with clear time varying patterns. A large share of this seemingly high level of integration is shown to be driven by common global factors. After filtering these factors from each stock market, the magnitude of interconnectedness falls substantially. Our results therefore suggest that stock market integration in East and Southeast Asia is not as strong as it looks. Although governments in this region have been promoting financial market collaboration and integration, barriers remain significant. The overestimated interconnectedness is mainly a simple reflection of stronger global influences on individual markets, while their interconnectedness attributable to non-global factors shows a descending trend after the crisis.     

US, UK and European Stock Market Integration

Abstract:   This paper examines long‐run convergence between US, UK and seven European stock markets. We report evidence to suggest that while real short‐run diversification gains may occur, in general they tend to be short‐lived. However we also find that US and UK markets are relatively less bound to a common trend, which would imply that increased stock market merger activity, and any transition to the European common currency by the UK, may lead to relatively large stock market adjustments as markets adapt to these institutional changes.     

Asia-Pacific Stock Market Integration: New Evidence by Incorporating Regime Changes

ABSTRACT

This work provides new evidence of Asia-Pacific stock market integration by incorporating the regime changes of each stock market through the smooth transition autoregressive (STAR) model. According to empirical results, most Asia-Pacific stock market returns follow STAR dynamics to a significant degree with more rapid and frequent regime changes of a shorter nature compared with G7 markets. A series of STAR-based Granger causality tests reveal evidence of stronger equity market integration compared with linear Granger causality tests. We also find that Asia-Pacific stock markets are integrated in different levels. Finally, we provide evidence that in the early twenty-first century the influence of China and the United States on Asia-Pacific stock markets has been maintained while that of Japan has been weakened.     

Economic interdependence and common stochastic trends: A comparative analysis between EMU and non-EMU stock markets

Whether economic interdependence among countries is a contributing factor to cointegration and common stochastic trends in international stock markets is indiscernible due to contradictory results from prior empirical work. This study aims to add clarity to this issue through a more distinct grouping of countries and methodological enhancements. A comparative analysis of cointegration is conducted between stock market price indices of major Economic and Monetary Union (EMU) and non-EMU countries. The conventional Johansen methodology is augmented with several diagnostic techniques (that have not been all inclusive in previous studies) to ensure the robustness of test results. Major findings pertinent to investors and policymakers are that economic interdependence appears to be the important contributing factor and that the U.S. stock market does not exert influences on long-run performances of other included stock markets. Furthermore, while the UK is not an EMU member, it may be viewed as a quasi EMU participant due to its stock market being cointegrated with and yet one of the common stochastic trends (besides those of Germany, Italy, and the Netherlands) within the EMU stock markets under investigation.     

Stock market integration between the UK and the US: Evidence over eight decades

This study investigates how the impact made on stock market integration by macroeconomic determinants such as various measures of convergence and financial volatility, as well as crisis episodes, varies over the period 1935–2015. We gauge how the level of integration between the UK and US stock markets changes across three monetary regimes during this period: pre–Bretton Woods (BW), the BW fixed exchange rate, and the post-BW flexible rates. Our empirical results suggest that integration was strongest under the post-BW regime and weakest under the BW regime. We further demonstrate that stock market integration between the two markets has been driven largely by macroeconomic convergence and financial volatility as well as by crises, especially since the demise of the BW system.     

Mean reversion in stock market prices: New evidence based on bull and bear markets

In this paper we test whether mean reversion in stock market prices presents a different behavior in bull and bear markets. We date the US bull and bear periods using Bry and Boschan (1971) algorithm. We examine the order of integration in the S&P 500 stock market index covering a daily period from August 1929 to December 2006 in bull and bear phases. Our results indicate the existence of different episodes of mean reversion, which mainly correspond to bull market periods.     

International portfolio diversification: an ICAPM approach with currency risk

This article investigates international stock market integration in four major developed economies, namely the United States, the Economic and Monetary Union of the European Union, Japan and the United Kingdom, and two Asian emerging, countries namely China and India, over the period from June 1994 to June 2009. To model stock market integration we estimate a dynamic version of the international capital asset pricing model (CAPM) in the absence of purchasing power parity. Conditional variance is modelled via a multivariate GARCH specification. To investigate the evolution of integration overtime we estimate the CAPM in sub-periods. In addition, we connect our results to the timing of world financial crises. Our findings show that the stock markets tend to move in parallel after June of 2002, although from 2002 to 2006 there have not been crises events. These results support the increasing globalization and interdependence of both emerging and developed markets in the recent decade, reducing the benefits of portfolio diversification.     

Volatility‐Spillover Effects in European Bond Markets

Volatility spillover from the US and aggregate European bond markets into individual European bond markets using a GARCH volatility‐spillover model is analysed. Strong statistical evidence of volatility spillover from the US and aggregate European bond markets is found. For EMU countries, the US volatility‐spillover effects are rather weak (in economic terms) whereas the European volatility‐spillover effects are strong. The bond markets of EMU countries have become much more integrated after the introduction of the euro, and in recent years they have become close to being perfectly integrated. The main driver of the integration appears to be convergence in interest rates.     

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.
