PurposeThis study aims to examine the influence of Islamic microfinance services (IMFS) on poverty reduction in the eastern part of Ethiopia.Design/methodology/approachA binary logistic regression model was used to analyze poverty reduction and income, education, household size, age and saving of IMFS through a semi-closed questionnaire by using a purposive sampling technique. A semi-closed interview with higher officials from an Islamic microfinance service was also used.FindingsThe study results show that the income, education, household size and age of the IMFS’ clients are the major influencing factors that affect poverty reduction in Ethiopia.Practical implicationsThe study’s findings provide insights for policymakers to revise intensively their regulations and directives for Islamic microfinance operators. It emphasizes the government’s role in serving the community’s interests through financial inclusion and in developing programs to enhance the effectiveness of Islamic microfinance operations in the poverty reduction process. As a social implication, Islamic microfinance service providers gain insights into how beneficiary-side variables contribute to the country’s poverty reduction after offering Islamic microfinance products to them.Originality/valueThe results of this study are distinctive because they show how poverty reduction in Ethiopia is influenced by how income level is increased, how better educational level is attained, how household size is managed and how well the age of the client is effectively used for productivity. The paper also provides a new view of Islamic microfinance in Ethiopia, its influencing factors for poverty reduction and challenges with the operating system.
