Abstract
This article examines how and to what extent direct market intervention by the Hong Kong government in both the stock and futures markets affected
the pricing relationship between the Hang Seng Index futures and the cash index during the period of the Asian financial crisis. The study avoids
infrequent trading and nonexecution problems by using tradeable bid and offer quotes for the constituent stocks of the index. The results show that
arbitrage efficiency was impeded during, and in the immediate aftermath of, the intervention. The findings suggest that discretionary government action
introduces an additional risk factor for arbitrageurs that continues to disrupt normal market processes even after the government ceases to intervene.
The continued disruption following the government's actions in the market also stems from a poorly developed stock loan market that impedes short
selling, as well as a lack of liquidity in the market. ยฉ 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:1159โ1189, 2003
