Abstract: With growing interest in the construction and application of a financial conditions index since the global financial crisis, this study constructs a Korean financial conditions index and examines the impact of the Korean financial conditions on future Korean GDP growth using quantile regression models. Considering that Korea is a small open economy, we also examine the spillover effects of the US financial conditions on the Korean GDP growth by including a US financial conditions index in the quantile regression model. The main empirical findings are as follows. First, the impact of Korean financial conditions on the future GDP growth of Korea is asymmetric in quantiles. The deterioration of financial conditions expands the left tail of the GDP growth distribution, while its impact on the right tail of the distribution is relatively weak. More interestingly, tight financial conditions make the distribution of next quarter’s GDP growth bimodal, implying a mixture of bank runs and no bank runs distributions. Second, the extended quantile regression model with US variables shows that the deterioration of US financial conditions expands both of the left and right tails of the distribution of the Korean GDP growth, increasing its variance. These results are robust with alternative financial conditions indexes and out-of-sample predictions.
