摘要

Although numerous studies have examined the effect of monetary policy on stock prices, empirical research in the international setting remains relatively scant. Therefore, this topic is reexamined in the context of Thailand. In a sample of 50 repurchase rate announcements of the Bank of Thailand during 2003-2009, our regression results suggest that the raw change in the repurchase rate has a negative effect on stock returns at the market level, which is inconsistent with the literature. Contrary to the results of numerous studies, we find that at the market level the expected change in the repurchase rate has a negative effect on stock returns and the unexpected change in the repurchase rate exhibits no effect on stock returns. However, the effect of the unexpected change in the repurchase rate on stock returns is evident at the firm level. Our findings also suggest that the stock market's response to the repurchase rate change is asymmetric. The unexpected change in the repurchase rate that is considered as good news has a negative effect on stock returns. Overall, the evidence lends support to the notion that the monetary policy announcements have a significant effect on stock prices and further adds to the debate on whether the creditability of the monetary authority may contribute to the stock market's response to the monetary policy actions.
