Abstract
This study examines the effectiveness of the Reserve Bank of India’s (RBI) intervention policy in the foreign exchange market. An attempt is made to capture volatility spillovers between the RBI’s intervention and exchange rate. The results indicate that the past volatility of intervention has a positive impact on the present volatility of the exchange rate. Similarly the past volatility of the exchange rate, increases the present volatility of intervention. The volatility of the exchange rate is more sensitive to its past shock than the past shock of an intervention. Similarly, the volatility of intervention is more sensitive to the past volatility of exchange rate compared to the past volatility of intervention.

Notes
Since, the data on buying and selling operation at less than monthly frequency is not available; we had to construct buying and selling operation by multiplying dummies (D1 for buying D2 for selling operation) with the percentage change in the foreign currency asset, when the changes are positive and negative respectively. RBI intervenes in the foreign exchange market by buying foreign exchange (US $), which in turn increases the stock of foreign currency asset and vice versa.
Ideally, we should employ the capital inflow and outflow as good news and bad news respectively. Instead, negative and positive changes in the 91 days US Treasury bill rate is chosen as proxy for good news and bad news respectively. Since the data on capital inflow and outflow is not available for the sample period. However, the proxy could efficiently capture the impact of good news and bad news on exchange rate.
