The purpose of this paper is to investigate the impact of Economic Policy Uncertainty (EPU) and 4 different category-specific economic policy uncertainty (monetary policy uncertainty (MPU), fiscal policy uncertainty (FPU), trade policy uncertainty (TPU) and foreign exchange policy uncertainty (FXPU)) on corpoarte trade credits for firms listed in the KOSPI market from 2000 to 2022. From the empirical results, we find that EPU and 4 category-specific policy uncertainty has a significantly negative effect on corporate trade credits, implying that when firms perceive the high EPU, they tend to hoard cash and tighten their trade credits due to precautionary motive. In addition, we observe that compared to the impacts of TPU and FXPU, those of MPU and TPU affect corporate trade credits to a less extent. Finally, the effects of EPU and category-specific EPU on corporate trade credits differ depending on the industry. Overall, our empirical results provide important implications for corporate managers regarding risk management and for policymakers on the firm-specific effects on their policy decisions.
