Abstract

This study analyzes the impact of economic uncertainty on the intermediation function of Islamic banks and conventional banks in Indonesia using time series data from January 2014 to April 2024 using the Autoregression Distributed Lag (ARDL) method. The results show that global uncertainty, measured by the World Uncertainty Index (WUI), has a positive influence on Islamic bank financing growth, but negatively impacts conventional bank credit growth in the short and long term. Furthermore, domestic economic uncertainty, reflected in inflation, has been shown to increase financing growth in both types of banks. Furthermore, the Consumer Confidence Index (CCI) and the rupiah exchange rate against the dollar have a positive influence on conventional bank credit growth, while other variables such as the BI Rate, Global Economic Policy Uncertainty (GEPU), the COVID-19 pandemic, and world oil prices do not affect the growth of Islamic financing or conventional bank credit. Policy implications recommend increasing incentives for Islamic banks and stricter supervision of conventional banks to address economic uncertainty
