The concept of market efficiency plays an important role in financial markets. The purpose of this study is to determine if there is any dynamic relationship between stock returns and government policy for international financial markets. Therefore, the relationships between real stock returns and growth of M2 for U.K., France, and Germany were investigated using time series methods to test causality by the following approaches. First of all, VAR approach and the Granger causality test. Second, the frequency docomposition approach and Geweke test. Using both tests, the empirical results showed that real stock returns (RSR) are caused by the growth of M2 (GM2) only in French data. This finding indicates that European stock markets are efficient in absorbing information about monetary policy except France.
