Onshore and offshore market for Indian rupee: recent evidence on volatility and shock spillover

The article empirically examines the onshor-offshore linkages of the Indian rupee using recently developed multivariate GARCH technique. The empirical results show that the offshore non-deliverable forward market does not have mean spillover impact on onshore spot, forward and futures markets while shocks and volatilities in the non-deliverable forward market influence the onshore markets. A key finding of the study is that the magnitude of volatility spillover from non-deliverable forward to spot market has accentuated after the introduction of currency futures in India. This development could be attributable to large arbitrage between futures and non-deliverable forward market in the more recent period. The finding has critical implications for exchange rate policy and management in the Indian context. There is need for close monitoring of both the onshore and offshore markets.
