In this article, we focus on interrelations between the returns on the stock market and the market for foreign exchange in six East Asian countries in the period before, during, and after the Asian financial crises in the period 1997–1998 and the Global Financial Crisis in 2008–2009 that originated in the United States. Since the growing significance of the Asian share in world trade and capital mobility, and the rapid growth in their domestic market capitalization over the past few decades (see Kohsaka 2004), Asian financial markets has prompted researchers, policy makers as well as analysts to carry out detailed analysis of the relationship between the stock market and the exchange rate market. The importance of modeling currency and equity markets simultaneously is supported by Dungey and Martin (2007), Lin (2012), and Tsai (2012). Rapidly increasing international equity investments creates a higher supply and demand for currencies, leading to some degree of interdependence between both markets. The wide fluctuations in the value of the currencies heightened the interest in the potential vulnerability of internationally active firms to foreign exchange risk. Moreover, positive spillovers of volatility between both markets may increase the international portfolio risk faced by international investors. This reduces the opportunities from international diversification and disturbs the asset allocation decisions. Therefore, the relationship between stock and foreign exchange markets is important to investigate especially in the case of highly volatile and unstable markets, that are typical of emerging economies.
