Exchange market pressure, stock prices, and commodity prices in West Africa

Abstract

As Africa continues its decade of rapid economic growth, the continent also faces the risk of becoming more susceptible to financial 'contagion.' Capital flows and trade linkages might cause one country's currency market to influence those of its neighbors. Likewise, shocks to global commodity or asset markets might induce a crisis in one or more countries in the region. This study generates monthly measures of exchange market pressure (EMP) for four individual West African countries, as well as for the WAEMU franc zone, from 2002 to 2012. Vector Autoregressive (VAR) methods are then used to test for linkages among them, as well as to analyze the effects of various external price shocks. A number of spillovers are uncovered. More importantly, local connections dominate global ones in the case of stock- and commodity-price declines. Ghana, for example, is shown to be a 'commodity currency' when West African commodity prices are included in the VAR, but not when a global index is used.
