In this paper study aims to investigate the relationship between call money rates, exchange rates and stock returns from the perspective of India. We use monthly data for the time span of April 1992 to March 2011. This provides sufficient data set for the empirical analysis. Result from Granger causality test evidences bidirectional relationship between call money rates and exchange rates. It is also identified that call money rates and exchange rates Granger cause stock returns and did not find reverse causality from stock returns to call money and exchange rates. To explore, lead-lag interaction among the variables studied we employed VAR models. Results suggest that there is substantial lead-lag relationship from call money rates to exchange rates and stock returns. Similar relationship also found from exchange rates to call money rates and stock returns. However, there is no evidence of lead-lag causation from stock returns to call money and exchange rates. Findings of this study are useful for the investors and policy makers. In investors’ standpoint, they can utilize this historical information of call money rates and exchange rates for predicting the movements of stock returns. Similarly, policy makers can stabilize the stock market fluctuations by adopting appropriate policies towards interest rates and exchange rates for time to time.
