In a world of high capital mobility, several risks are emerging in the financial markets and the Central Bank intervention has played an important role in managing these risks. In India, the Reserve Bank of India (RBI) intervenes in the foreign exchange market to maintain orderly market conditions. This article empirically explores the relationship between Central Bank intervention and exchange rate behaviour in the Indian foreign exchange market. Specifically, the article investigates the effects of RBI intervention on exchange rate level and volatility. Using monthly data for April 1995 through December 2006 and GARCH (1,1) model, it is found that the intervention of the RBI is effective in reducing volatility in the Indian foreign exchange market instead of reversing trend movement of exchange rate. It is also observed that FII investments increase exchange rate volatility in India.
