Social finance, institutional quality and stability of Islamic banks: evidence from four countries

Abstract

Purpose Islamic banks, despite being Shariah-compliant, have long been criticized for mimicking conventional banks in terms of their products and processes (Khan, 2010; Kuran, 1996). However, several Islamic banks do engage in philanthropy ( zakat and charity) and risk-sharing financing ( mudarabah and musharakah ) instruments that better meet their raison d'etre, the fulfillment of Maqasid al-Shariah (Jatmiko et al ., 2023). These contracts, however, are more susceptible to moral hazard and adverse selection problems than traditional debt-based finance (Azmat et al ., 2015) and may impair Islamic bank stability. This paper explores the relationship between social finance and the stability of Islamic banks, and whether institutional quality moderates this relationship. Design/methodology/approach Using hand-collected annual data on social finance from 12 Islamic banks in four countries: Bangladesh, Bahrain, Indonesia and Malaysia, between 2006 and 2019, the authors employ the feasible generalized least squares and the panel-corrected standard errors methods for the analysis. The Stata version 16 software was used to analyze the data for the study. Findings The results indicate that mudarabah and musharakah financing raises the stability of Islamic banks. The authors also found that mudarabah and musharakah expose Islamic banks to more risk-taking behavior amidst the conditioning effect of institutional quality. On the other hand, charity induces the stability of Islamic banks, while zakat increases the risk-taking behavior of the banks. Further, when the quality of institutions was used as a moderator, both zakat and charity induced the stability of Islamic banks. The results were robust when liquidity risk was used and partially robust when portfolio risks were employed as measures of stability. Research limitations/implications One concern regarding the application of Islamic social finance is that it might be a risky strategy for Islamic banks. In terms of research implications, the available evidence suggests that the use of Islamic social finance instruments is not detrimental to the stability of Islamic banks. Hence, regulators and policymakers should not penalize Islamic banks for using Islamic social finance instruments that help provide financial solutions to the underserved and unserved. In terms of research limitations, the study could not include other relevant Islamic social finance instruments such as waqf and qard al-hassan . Furthermore, data availability restricts the analysis to only 12 Islamic banks in fourcountries. As more Islamic banks in different countries venture into Islamic social finance, and the quantity and quality of information improve, future studies could explore the issue further. Social implications The available evidence suggests that the use of Islamic social finance instruments does not worsen the stability of Islamic banks. Given the dominance of sale- and lease-based contracts in Islamic financing (Aggarwal and Yousef, 2000; Šeho et al ., 2020), these findings should encourage other Islamic banks to provide financial solutions using other Shariah-compliant contracts including those based on risk-sharing and philanthropy. This would be a better reflection of the Islamic banks’ value proposition as it helps boost social activities that have a high impact on the activities of small businesses, contributing to the real economy and promoting well-being in society. Originality/value Previous studies mainly relied on mudarabah , mushakarah and zakat separately as they relate to the performance of Islamic banks. This study explores the impact of social finance which includes charity and zakat to examine their impact on Islamic banks’ stability. Further, the authors use institutional quality as a moderating variable in the relationship between Islamic social finance instruments and the stability of Islamic banks.
