Financial leverage, percentage of female borrowers and financial sustainability of microfinance institutions

PurposeThis paper examines the influence of financial leverage on the financial sustainability of microfinance institutions (MFIs) and the moderating role of the percentage of female borrowers (PFB).Design/methodology/approachThe study uses a global sample of 646 MFIs drawn from the World Bank Mix Market and panel data for 2010-2018. The study employs ordinary least squares (OLS) and the one-step system generalized method of moments (SGMM) as regression estimation methods.FindingsThe findings of this study reveal that financial leverage and the PFB have a negative and significant effect on financial sustainability. The findings further show that the interaction between financial leverage and the PFB positively affects the financial sustainability of MFIs.Practical implicationsThe findings inform MFIs' managers on the adverse effect of financial leverage and the PFB in their quest for financial sustainability. The findings also demonstrate that MFIs can leverage female borrowers to reverse the adverse effect of financial leverage on financial sustainability of MFIs.Originality/valuePrevious studies examined the direct effect of financial leverage and reported incongruent results. Because female borrowers are at the epicenter of MFI lending, this study fills the gap in the literature by examining whether the proportion of female borrowers moderates the relationship between financial leverage and MFIs' financial sustainability using a global dataset.
