This paper examined the short and long run correlating, causal and co-integrating relationship between Indian and other major developed [Australia, Canada, France, Germany, Japan, United Kingdom (UK) and United States of America (USA)] and developing [Argentina, Brazil, China, Mexico, Russia, and South Africa (SA)] markets for the period from April 2003 to December 2014 which was further subdivided in two sub periods: a Pre-crisis period (April 2003 to August 2007) and a Post-crisis period (August 2007 to December 2014). We applied correlation analysis, short and long run granger causality and Johansen Co-integration techniques on the monthly adjusted closing indices values of representative market indices.
Overall, results show that India had high correlating, causal and co-integrating relationship with Brazil, China, Russia and South Africa from the developing block and with Australia and Canada amongst the developed economies. This could be due to large bi-lateral trade and/or close political and cultural ties between these countries like the official BRICS group. Also, while the correlations significantly reduce post crisis, causal and co-integrating relationships increase post crisis. So, the nature of relationship between these markets has shifted from being contemporaneous to more of lead-lag nature. Thus, we find evidence for increase in contagion post crisis.
This has important implications for all stakeholders. Policy makers and stock market regulators need to be vigilant and take steps to insulate domestic markets as crisis is evidenced to greatly accentuate contagion. Investors can work out possible arbitrage opportunities as we find evidence of several lead-lag relationships among these markets. International investors can breathe easy regarding their international portfolio diversification as we find support for declining correlations among these markets.
