This study examines the tendency of low-income economies in ECOWAS to converge with their high-income neighbors. It extends the frontier of knowledge by ascertaining how quickly financial development (FD) and foreign direct investment (FDI) would stimulate growth, causing low-income ECOWAS member states to catch up. Also, the required threshold for FD and FDI required to facilitate convergence were computed. To achieve the above, fifteen ECOWAS member states were examined within the period ۱۹۹۰ to ۲۰۱۷ using panel data obtained from the World Development Indicators (WDI) ۲۰۱۸ database. The Fully Modified Ordinary Least Square (FMOLS) technique of analysis was utilized and the study found an absence of conditional convergence among ECOWAS member countries. More so, the FD-FDI threshold level required to aid conditional convergence is ۲۲.۸% and ۳.۷۷% respectively. Therefore to ensure convergence, the study recommends that low-income member states must thrive to attract FDI and seamless credit to the private sector.
