Financial Inclusion, Capital Accumulation and Agricultural Output Growth in Nigeria: Evidence from 1993-2024

Abstract

This study examines long-term trends in financial inclusion and their implications for capital accumulation and agricultural output growth in Nigeria from 1993 to 2024. Using national indicators of demand-side and supply-side financial inclusion, alongside agricultural GDP and gross fixed capital formation, the analysis documents a structural transformation of Nigeria’s financial system from widespread exclusion to digitally driven inclusion. Financial inclusion expanded rapidly after 2012, driven by fintech adoption, agent banking, and regulatory reforms, with the share of formally included adults rising from below 25% to over 65%, and financial exclusion declining sharply. Supply-side infrastructure particularly POS terminals and agent networks grew exponentially, indicating a shift from physical banking to digital delivery channels. A composite Financial Inclusion Index increased steadily from 0.22 in 2012 to 0.76 in 2023, confirming broad-based access expansion. Agricultural GDP and capital accumulation exhibited sustained upward trends, particularly after the mid-2000s, coinciding with financial sector reforms and targeted agricultural finance interventions. However, private sector credit growth lagged behind access expansion, revealing a persistent gap between financial inclusion breadth and credit depth. Despite rising account ownership and transaction access, agriculture continued to receive a disproportionately small share of formal credit, limiting the translation of inclusion gains into productive investment. The findings indicate that Nigeria’s financial inclusion progress has been largely transactional rather than investment-oriented. Policy efforts should therefore shift from access expansion toward credit deepening by strengthening agricultural finance, linking digital financial services to productive investment, improving risk-sharing mechanisms, and promoting long-term capital formation to support sustained agricultural output growth and inclusive economic development.
