Did Baltic stock markets offer diversification benefits during the recent financial turmoil? Novel evidence from a nonparametric causality-in-quantiles test

Motivated by financial liberalization investors seek for new investment opportunities through international portfolio diversification. To this end we explore any asymmetric causal relationship between developed European stock markets (Germany, France and UK) and emerging Baltic markets namely; Estonia, Latvia and Lithuania. Our analysis focuses on the period before and after countries’ EU accession and pre- and post the global financial crisis. For this purpose, both the standard parametric test for causality and a novel nonparametric test for causality-in-quantiles are employed. The results of both the parametric and nonparametric Granger causality test support a causal relationship in mean that runs from all of the major markets to the Baltic markets across both samples. The results imply the existence of significant nonlinear return and volatility spillover from European markets to Baltic markets. Policy implications for international investors are also discussed.     

Spillovers of the Conventional and Unconventional Monetary Policy from the US to South Africa

This paper assesses the effect of US monetary policy on South Africa during the period 1990–2018. We separately analyse and compare the effect of conventional monetary policy, before the Global Financial Crisis, and unconventional monetary policy, after the US monetary policy reached the zero-lower bound. Our impulse response function results indicate that monetary policy in South Africa responds mainly to local inflation, economic activity and financial conditions. While there is strong correlation between the global and South African financial cycle, the financial cycle is not transmitted to the real economy because of the sluggish response of industrial production and domestic credit, especially after the global financial crisis. We see this as an indication of the effects of structural issues to the real economy and constrained households’ balance sheet which has prevented the local economy to take advantage of low local interest rates and the global economic recovery after the crisis.
