Digitalization and diversification strategies for effective bank liquidity management in emerging markets

The purpose of this study is to examine the impact of income, assets, and geographic diversity on bank liquidity in the Indonesian banking sector. This study uses purposive sampling and multiple regression analysis (MRA) to investigate the impact of digital banking on bank liquidity, as measured by the loan-to-deposit ratio (LDR) and liquidity ratio. The sample used is 87 banks in Indonesia, which include state-owned banks, commercial banks, regional development banks, and Islamic banks. The key findings of this study indicate that income and asset diversification significantly affect bank liquidity, with income diversification having a negative effect on the Loan-to-Deposit Ratio (LDR). The use of digital banking simplifies the relationship between diversification strategy and liquidity, thereby improving banks' ability to manage liquidity. However, despite digital integration, asset diversification continues to show an adverse correlation with liquidity, indicating limitations in its effectiveness. The study concludes that while digital banking enhances the effect of income diversification on liquidity management, it limits its effect on asset diversification. This suggests that digital utilization is a strategic resource for increasing liquidity, although it requires focused implementation. These findings offer important insights for bank management and policymakers in formulating digital transformation plans that enhance efficient cash management and financial stability, particularly in developing countries like Indonesia.
