Financial Inclusion and Poverty Reduction in Developing Countries: A Systematic Review and Meta-Analysis of Empirical Evidence

Abstract

In developing countries, financial inclusion has become a central component of development policy aimed at reducing poverty and promoting inclusive economic growth. Expanding access to financial services, including savings, credit, digital payment systems, and insurance, may enhance household welfare by enabling individuals to manage risks, accumulate assets, and invest in productive activities. However, empirical evidence regarding the effectiveness of financial inclusion in reducing poverty remains mixed and context-specific. A systematic review and meta-analysis of empirical studies examining the relationship between financial inclusion and poverty reduction in developing countries. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive literature search was conducted across Scopus, Web of Science, EconLit, and Google Scholar for studies published between 2000 and 2024. Eligible studies empirically assessed financial inclusion interventions and poverty-related outcomes, including income, consumption, household welfare, and asset accumulation in developing economies. Following predefined inclusion and exclusion criteria, 52 studies were included in the qualitative synthesis, of which 31 provided sufficient quantitative data for meta-analysis. Financial inclusion was generally associated with poverty reduction and improved household welfare. Access to financial services contributed to increased savings, improved consumption stability, greater resilience to economic shocks, and enhanced opportunities for entrepreneurship and small business development. The meta-analysis demonstrated a statistically significant relationship between financial inclusion and poverty reduction, although effect sizes varied by financial service type and geographic context. Digital financial services, particularly mobile money platforms, showed relatively strong poverty-reducing effects through lower transaction costs, improved remittance flows, and expanded access among previously unbanked populations. Savings products also demonstrated consistent positive welfare effects, whereas evidence regarding microcredit was mixed, with variable impacts on entrepreneurial activity, income generation, and household poverty indicators. Financial inclusion can contribute meaningfully to poverty reduction and inclusive economic development in developing countries; however, financial access alone is insufficient to eliminate poverty. Its effectiveness depends on broader socioeconomic and institutional conditions. Comprehensive financial inclusion strategies should therefore integrate digital financial innovation, consumer protection, financial literacy, gender-sensitive approaches, market access, and wider development interventions to maximise poverty-reducing impacts.
