Do global factors impact BRICS stock markets? A quantile regression approach

This paper examines the dependence structure between the emerging stock markets of the BRICS countries and influential global factors. Using the quantile regression approach, our results for the period from September 1997 to September 2013 show that the BRICS stock markets exhibit dependence with the global stock and commodity markets (S&P index, oil, and gold) as well as changes in the U.S. stock market uncertainty (CBOE Volatility Index). This dependence structure is often asymmetric and affected by the onset of the recent global financial crisis. By contrast, the U.S. economic policy uncertainty has no impact on the BRICS stock markets.     

The global financial crisis,financial linkages and correlations in returns and volatilities in emerging MENA stock markets

The 2007 United States financial crisis has developed into the most severe worldwide economic crisis since the 1927 Great Depression. In addition to its severe repercussion in North America and the European Union, the crisis has put pressure on emerging markets in general, and the Middle East and North Africa region in particular. For a better understanding of how the crisis affected the MENA region, we focus in this paper on the global and regional financial linkages between MENA stock markets and the more developed financial markets, and on the intra-regional financial linkages between MENA countries' financial markets.     

Oil and stock markets before and after financial crises: A local Gaussian correlation approach

The effect of financial shocks on the cross‐market linkages between oil prices (spot and futures) and stock markets is examined for four major crises. We employ the local Gaussian correlation approach and find that the two markets were regionalized for most of the 1990s and the early 2000s. Flights from stocks to oil occur in all crisis episodes, except the recent global financial crisis. The view that stock and oil markets behave like “a market of one” after the financialization of commodities is further supported by the presence of contagion between US stock markets and all the benchmark oil markets.     

The global financial crisis: An analysis of the spillover effects on African stock markets

This paper examines the relative importance of the global and regional markets for financial markets in developing countries, particularly during the US financial crisis and the European sovereign debt crisis. Specifically, we examine the way in which the degree of regional (seven African markets combined), global (China, France, Germany, Japan, the UK and the US), commodity (gold and petroleum), and nominal effective exchange rate (Euro and US dollar) spillovers to individual African countries evolved during the two crises through the econometric method introduced by Diebold and Yilmaz (2012). We find that African markets are most severely affected by spillovers from global markets and only modestly from commodity and currency markets. Conversely, regional spillovers within Africa are smaller than global ones, and hence, African markets are insulated from global crises. We also find that the aggregated spillover effects of European countries to the African markets exceeded the corresponding effects of the US, even in the wake of the US financial crisis.     

Risk substitution in cryptocurrencies: Evidence from BRICS announcements

We investigate the impact of BRICS regulatory announcements on cryptocurrency volatilities and returns. Results evidence risk substitutions after announcements moving from ETH, XRP and LTC to BTC and vice versa, with BTC having volatility reactions to regulatory announcements that differ from those of other cryptocurrencies. Bootstrap quantile regression indicates a stronger detrimental impact of announcements when BTC is currently manifesting lower volatility and higher daily returns. Robustness checks confirm our findings, as well as evidence that the cryptocurrencies in our sample are considerably more reactive to BRICS announcements than US Fed announcements, suggesting important linkages between emerging markets and cryptocurrencies.     

Spillover Effects among European,the US and Moroccan Stock Markets before and after the Global Financial Crisis

ABSTRACT

This paper assesses return and volatility spillovers among stock markets in Morocco, the US, UK, France and Germany represented respectively by MASI, S&P 500, FTSE 100, CAC 40 and DAX 30 indices, both before and after the global financial crisis (GFC) of 2008. The daily frequency data cover the period from January 2nd, 2002 to June 30th, 2016. Using the Diebold and Yilmaz approach, the results show varying financial connectedness between the Moroccan and the above mentioned developed stock markets. In fact, the significant increase of spillover index during the post-financial crisis period demonstrates that the US and European stock markets were the most affected. On the other hand, despite a relative increase of spillover effects coming from the US and German equity markets, our results show decline in the total net spillovers experienced by the Moroccan market after the recent financial crisis. These findings may provide some useful information to support decision-making and trading strategies for international investors.     

Household characteristics and the change of financial risk tolerance during the financial crisis in the United States

This study examines how household financial risk tolerance is affected during the period of 2007 and 2009, which covered the eve and trough of the financial crisis in the United States and what types of households are associated with the change of risk tolerance. Risk tolerance is measured by two objective indicators, narrowly and broadly defined stock ownership, and a subjective indicator, risk taking attitude. Using panel data from 2007 to 2009 Survey of Consumer Finances, results show that during the financial crisis, the households in general are more risk averse, indicated by withdrawing from stock markets and holding a less risk taking attitude. In addition, Black and Hispanic households are more likely and households with higher education are less likely to withdraw from stock markets. Older households are less likely to change in risk tolerance during the financial crisis, as are richer households. The findings show panel data could generate novel results and contribute to the literature of financial risk tolerance.     

International financial integration: Stock return linkages and volatility transmission between Vietnam and advanced countries

This paper investigates the interdependence between the Vietnamese stock market and other influential equity markets in terms of return linkage and volatility transmission covering the period including pre, during and post the 2008 Global Financial Crisis. A VAR model is utilized to estimate the conditional return linkage among these indices and a GARCH-BEKK model is employed to investigate the volatility transmission. We find evidence of statistically significant correlation, return spillover and volatility linkage between Vietnamese stock market with other leading equity markets of the US, Hong Kong and Japan. Moreover, we find that during the financial crisis, stock markets become more interrelated.     

Emerging markets before the 1997 Asia Pacific financial crisis

This study investigates which Asia Pacific markets were driven by the US stock market and which by the Japanese stock market during the 1995-97 period, right before the 1997 Asia Pacific financial crisis. The results show that stock markets of Hong Kong, Indonesia and Malaysia shared a long-run equilibrium relationship with the US stock market. The stock market of the Philippines was linked with both the US stock market and the Japanese stock market, while stock markets of Thailand and South Korea did not appear to be influenced by either. Countries whose capital markets had a co-integrating relationship with the US market pegged their national currencies closely to the US dollar.     

Clustering in emerging equity markets

We consider pairwise tail behavior of return series for identifying the most important emerging markets clusters. Pairs of markets belonging to the same group present similar type and strength of interdependence during stressful times, represented by a common copula and a statistically equivalent measure of tail dependence. By collapsing data from d markets in to a group we overcome the difficult problem of finding their (higher dimensional) d-variate distribution. Results may help portfolio managers to deal with risk due to co-movements within clusters. We provide examples on how this can be done. Our study contributes to the discussion about the international association among stock markets during turbulent periods, and does not confirm the intuition that the observed association between extremes should be credited to linkages to leading markets. The study also confirms the importance of stock selection, particularly among the non-dominant stocks, instead of holding market-value weighed portfolios of stocks from countries within the same region.     

Dynamic interdependence of ASEAN5 with G5 stock markets

We find ASEAN5 and G5 stock markets are weakly linked in normal conditions. ASEAN5 markets became more connected with G5 markets during global financial crisis, with stronger conditional correlations, a higher level of risk spillover-connectedness and intensive causal risk dependence. By implications, ASEAN5 stocks are both return enhancers and risk diversifiers in boom market conditions. The diversification benefits remain even during crisis times, albeit lesser. Over the longer term, the diversification benefits of a portfolio that includes both ASEAN5 and G5 stocks are recaptured as market linkages revert to some lower levels due to decreased crisis contagion.     

Shift‐contagion Vulnerability in the MENA Stock Markets

As part of a broader financial development reform agenda, the Middle East and North Africa (MENA) countries have successfully expanded and revitalised their stock markets over the last decade. Whereas previous contributions have investigated efficiency, international integration and portfolio diversification opportunities, very little is known about these markets’ vulnerability to external financial crises. In this paper, we investigate shift‐contagion to the MENA region using a comprehensive battery of econometric tests for a number of different crises episodes: the 1997 Asian crisis, the 1998 Russian virus and its Brazilian sequel, the 2000 Turkish collapse, the 9/11 turmoil, the 2001 Argentinean crisis, the 2002 Enron/WorldCom scandal and the 2007–09 global financial crisis. We found that Turkey, Israel and Jordan were the most vulnerable markets over the 1997–2009 period, followed by Tunisia, Morocco, Egypt and Lebanon. Our results also highlight heterogeneous but increasing levels of sensitivity to external financial shocks, especially during the recent global financial crisis. From a financial point of view, this suggests that MENA‐based diversification strategies may be relatively inefficient during periods of global turmoil. From an economic point of view, our results suggest that stock market development also involves potential destabilisation costs. This issue should be acknowledged and addressed by policymakers if these countries are to ensure a smooth transition towards international financial integration.     

Monetary Policy,Vagabonding Liquidity and Bursting Bubbles in New and Emerging Markets: An Overinvestment View

‘Capitalism without failure is like religion without sin’. Charles Kindleberger's book Manias, Panics and Crashes points out that speculation and crises have always been present: the world economic crisis of the 20th century, the South Sea bubble in the 18th century, and the tulip mania in the first part of the 17th century. Starting with the Japanese bubble in the 1980s we take the reader on a tour through 20 years of bubbles in emerging markets and industrial countries which have recently culminated in the 2007/08 US subprime market crisis. We explain the global stock market and real estate booms based on the real and monetary overinvestment theories of Hayek, Wicksell and Schumpeter, arguing that ample liquidity supply originating in the large industrialised countries has contributed – independent from the exchange rate regime – to overinvestment cycles in new and emerging markets around the globe. The policy implication is to keep interest rates not too low for too long in response to bursting bubbles.     

Dependence between the global gold market and emerging stock markets (E7+1): Evidence from Granger causality using quantile and quantile‐on‐quantile regression methods

This study examined the dependence between gold and stocks during 2002–18 in seven emerging countries. The study combined the bivariate cross‐quantilogram introduced recently with quantile‐on‐quantile regression (QQR) approaches to conduct comprehensive and complementary analyses. The QQR results for the full sample revealed a weak positive dependence in all the quantiles of gold and stock returns across all the countries selected during mild market conditions. The results for pre and post‐crisis periods largely were consistent with those obtained for the full sample, except for Turkey (pre‐crisis), and China and Indonesia (post‐crisis). The results of the causality test‐in‐mean (return) and that of the causality test‐in‐variance revealed no causal relation between stock and gold in the pre‐crisis period, while causality ran only from gold to some stocks in the post‐crisis period. Further, while there was volatility causality running only from gold to stocks during the pre‐crisis period, the volatility causality between the two markets was very high during the post‐crisis period. Therefore, we suggest that gold may have been a hedge for stocks during the pre‐crisis compared to the post‐crisis period. Further, international risk factors should be considered in optimal investment decisions between domestic and global markets' assets (stocks and gold).

Fear Linkages Between the US and BRICS Stock Markets: A Frequency-Domain Causality

Abstract

We employ a spectral causality approach to uncover short-, medium-, and long-run causal relations between the US implied volatility index and the five individual implied volatility indexes of BRICS markets from 16^th March 2011 to 31^st January 2018. We show that the volatility causal relations differ between the short and long run in many cases. Although the results indicate the dominant role played by US uncertainty in shaping uncertainty in all BRICS markets, there is also evidence of a feedback effect from Brazil, Russia, and China to the US that differs across the spectrum. The implications for hedging and risk management practices are explored.     

Financial connectedness of BRICS and global sovereign bond markets

The paper examines the financial connectedness via return and volatility spillovers between Brazil, Russia, India, China and South Africa (BRICS) and three global bond market indices represented by the United States of America (USA), European Monetary Union (EMU) and Japan for the period 01 January 1997 to 27 July 2016 (weekly data). We find that Russia followed by South Africa is the net transmitter of shocks within BRICS, implying that the risk arising from these markets may have an adverse impact on others in BRICS. However, China and India exhibit weak connectedness, suggesting that these markets may be useful for hedging and diversification opportunities in BRICS. The networks of pairwise spillover results further confirm this. Among global indices, China appears as highly interconnected with the USA. USA is the strongest transmitter of shocks to BRICS bond indices. The panel data results further confirm the significant determinants of net directional spillover. Thus, we can conclude that BRICS is a heterogeneous asset class even in the case of the bond market. India and China are the markets to look for better risk management strategies.     

Emerging Asia: Decoupling or Recoupling

In this paper, we investigate the degree of real economic interdependence between emerging East Asian and major industrial countries to shed light on the heated debate over the ‘decoupling’ of emerging East Asia. We first document the evolution of macroeconomic interdependence for emerging East Asian economies through changing trade and financial linkages at both the regional and global levels. Then, by employing a panel vector autoregression (VAR) model, we estimate the degree of real economic interdependence before and after the 1997/98 Asian financial crisis. Empirical findings show that real economic interdependence increased significantly in the post‐crisis period, suggesting ‘recoupling’, rather than decoupling, in recent years. Output shocks from major industrial countries have a significant positive effect on emerging East Asian economies. More interestingly, the reverse is also true. Output shocks from emerging East Asia (and China) have a significant positive effect on output in major industrial countries. The result suggests that macroeconomic interdependence between emerging East Asia and industrial countries have become ‘bi‐directional’, defying the traditional notion of the ‘North–South relationship’ as one of ‘uni‐directional’ dependence.     

Tail-event driven NETwork dependence in emerging markets

This paper employs the Tail Event NETwork (TENET) to identify financial markets with greater potential risk, and simultaneously investigate the interdependence between them. We find strong time-varying connectedness across 23 emerging markets during the main crisis episodes, including the most recent COVID-19 pandemic, using data from January 1995 to May 2021. The network analysis revealed that emerging European markets are top risk transmitters, whereas emerging Asian markets are top risk receivers. China showed disconnection from the network, reflecting its diversification potential for investors. Our findings offer several policy and regulatory implications.     

The Effect of 2008 Crisis on the Volatility Spillovers among Six Major Markets

The scope of this paper is to determine whether global stock markets function differently under conditions of economic crisis by measuring volatility spillovers between six major markets, namely the US, the UK, Germany, Spain, Turkey, and Greece. We examine the volatility spillover effects of the 2008 US financial crisis to these six major markets using daily stock returns from January 2003 to December 2014, before, during, and after the 2008 financial crisis. We combine the Diebold and Yilmaz methodology with the stochastic volatility model of Taylor implemented through the sequential Efficient Importance Sampling method of Richard and Zhang to obtain variance decompositions derived from an estimated vector autoregressive model. The empirical findings suggest that stock markets tend to show increased volatility spillovers during the crisis period, thus resulting in lesser diversification benefits for investors.
