The asymmetric impacts of international portfolio flows on Australian dollar returns

This study investigates how equity portfolio flows affect the transition processes of exchange rate returns in Australia by employing a Markov-switching AR-GARCH-Jump model with time-varying transition probabilities. Three interesting findings are observed. Firstly, both GARCH and jump effects are totally different in the high-volatility and low-volatility states. Secondly, the net equity portfolio inflows increase exchange rate market fluctuations. Thirdly, the marginal effect of net equity flows is stronger in low-volatility state than in high-volatile state.
