Sand or grease effect? The impact of Islamic banking on the social mission of microfinance institutions

Purpose - Islamic banking and microfinance institutions (MFIs) share the core objective of serving the underprivileged. This study aims to investigate whether Islamic banking development facilitates (greases) or hinders (sands) the social mission of MFIs. Design/methodology/approach - Data for 19 countries covering the period 2010–2018 were collected from the World Bank, Bank Focus and International Monetary Funds and analyzed using conventional econometric methods. Endogeneity-corrected techniques and alternative proxies were employed to ensure robust results. Findings - The study revealed that Islamic banking development (proxied by the size of the Islamic banking assets) weakens the depth of outreach of MFIs (measured by average loan size). In countries with growing Islamic banking, MFIs appear to shift their focus toward wealthier clients, potentially due to market saturation among the poor. This is evidenced by MFIs offering larger loans, suggesting a mission drift toward profit maximization. Therefore, it can be inferred that competition from Islamic banks, to some extent, erodes the social mission of MFIs. Originality/value - This study is among the few to examine the recent and comprehensive relationship between Islamic banking development and the social mission of MFIs.
