Governance perspective and the effect of economic policy uncertainty on financial stability: evidence from developed and developing economies

Economic Policy Uncertainty (EPU) research has grown in importance in today's highly volatile and interconnected economy. This work investigates the relationship between EPU and Financial Stability (FS) (i.e., Z-scores and non-performing loans (NPL)) with the mediating variable of governance quality through a 23-country panel data from 2005 to 2019. The System Generalized Method of Moment (SYS-GMM) is adopted to address the issue of endogeneity, which is common in panel data regression. The two-stage Sequential of the Linear Panel Data Model (SELPDM) was also used to test the robustness of the results. According to the findings, EPU has a significant negative effect on financial stability (measured by the Z-score) and a significant positive effect on financial stability in the banking industry of most developed economies (proxied by NPL). We also discovered that good governance can be used to mitigate the negative effects of EPU on financial stability; however, this influence varies depending on region, bank, and market structure, and it was significantly greater during the global financial crisis. Finally, this study can help financial managers and policymakers develop appropriate policies to understand how banks respond to EPU.
