Abstract

The purpose of this paper is to examine the relationship between political uncertainty and the Thai stock market. The news-based index of Luangaram and Sethapramote (2018; 2020) is employed to capture the dynamics of political uncertainty from the second quarter of 1997 to the second quarter of 2020. The results reveal interesting evidence. Firstly, market volatility increases during periods of high political uncertainty. However, the effect on short-run stock returns is insignificant. Secondly, stock prices respond significantly to political uncertainty in the negative direction based on the vector autoregression (VAR) model. The effects are strongest in the second to fourth quarters. Finally, the findings reveal that political uncertainty pushes up the equity risk premium, and the impact is strongest at the extreme lower quantiles of return distributions.
