Several studies in the literature have identified the critical role of financial technology (fintech) in improving socio-economic conditions of nations, measured by human development index (HDI). However, despite the efforts to increase HDI using fintech, the ranking of African countries on the index table remains low. Given that access to electricity is imperative for fintech and fundamental to human development, we provide novel evidence by investigating the degree to which the prevailing energy poverty in Africa affects the success of fintech on human development in the continent. Our results show that fintech has a significant positive impact on human development and the impact remains consistent irrespective of the estimation methods employed. However, when we split our sample based on regions and income classification proposed by the World Bank, our results show that the impact of fintech on HDI is more pronounced in the uppermiddle, high-income, Eastern, Central and Southern countries. The Western countries have not significantly benefitted from fintech adoption, perhaps because those countries fall in the low-income categories and have a high prevalence of energy challenge. In the light of the current state of human development in Africa, our study advocates for more investments in energy infrastructure for the rapid realization of the gains of fintech.
