Abstract

This study examines the empirical validity of the weak-form Effi cient Market Hypothesis (EMH) for the foreign exchange market of Sri Lanka, using a battery of (univariate and panel) unit root tests, including those that allow for structural breaks. Monthly exchange rates for four major currencies (Indian rupee, UK pound, US dollar and Japanese yen) vis-à-vis the Sri Lankan rupee are considered in the empirical analysis. The results indicate that the four exchange rates studied follow a random walk, thus supporting the validity of the weak-form EMH. These results have strong implications for the participants of the foreign exchange market of Sri Lanka and government policy makers.
