The study is an attempt to investigate an analysis of bank intermediation and economic growth; the Nigeria experience: using ARDL estimation for a quarterly period from 2009-2022. Bank intermediation variables for the study are Credit to Private Sector, Unstructured Supplementary Service Data, Automated Teller Machine, Point of Sales and Bank Deposits while economic performance is proxy by Total Investment. The ARDL error correction model shows that credit to private sector (CPS) has a positive but insignificant effect on total investment. Also, USSD transactions have a positive but insignificant impact on total investment. Automated teller machine (ATM) had positive but insignificant effect on total investment in Nigeria. Finally, Bank deposit (BDD) had a positive but insignificant impact on total investment. The study therefore concludes that bank intermediation has a significant impact on economic growth in Nigeria. The study therefore recommends that increase access to credit for the private sector by implementing policies and measures to stimulate economic growth and promote total investment.
