Shift-Volatility Transmission in East Asian Equity Markets: New Indicators

Benjamin KEDDAD, Marcel ALOY, Gilles DE TRUCHIS, Gilles DUFRÉNOT

This paper attempts to provide evidence of “shift-volatility” transmission in the East Asian equity markets. By “shift-volatility”, we mean the volatility shifts from a low level to a high level corresponding respectively to tranquil and crisis periods. We examine the interdependence of equity volatilities between Hong-Kong, Indonesia, Japan, Malaysia, the Philippines, Singapore, Thailand and the United States. Our main issue is whether shift-volatility needs to be considered as a regional phenomenon, or from a more global perspective. We propose several indicators that are be useful to guide the investors in their arbitrage behavior in the different regimes: the duration of each state, the sensitivity of the volatility in a market following a change in the volatility in another market. Finally, we are able to identify which market can be considered as leading markets in terms of volatility.
