ABSTRACT Remittances are household income from foreign economies arising mainly from the temporary or permanent movement of people to those economies. Remittances inflow from the Nigerian abroad have become one of the mainstays of the Economy as it contributes to increase in household income. This is because, the year 2022 World Bank report showed that, Nigeria is the second-largest recipient of remittances on the Africa continent after Egypt as her annual remittance inflows stood at over $22 billion. Also, in first half of year 2026, Nigeria recorded $947million in diaspora remittance. In lieu of the background above, the study examined remittance inflows and economic growth in Nigeria from 1990-2024. The objective of the study is to; examine the effect of migrant remittances inflow on economic growth in Nigeria. Thus, secondary data on migrant remittances inflow and real gross domestic product (RGDP) were collected from World Bank indicators and Central Bank of Nigeria statistical bulletin. The technique of Generalized Method of Moments (GMM) was used to analyze the data after subjecting the data to ADF unit root test of stationarity. The unit root test result showed that, both the dependent and independent variables were stationary at order one. The empirical findings showed that, remittance inflow has positive relationship and significant impact with economic growth. In like manner, remittance outflow has positive relationship and significant impact with economic growth. Based on the findings, it was recommended amongst other that, remittance inflows should be invigorated in order to finance investment and also to overcome liquidity constraints which in the long run led to economic growth in Nigeria. Also, the study recommended policies that reduce the cost of formal remittance transfers, stabilize and promote productive investment of remittances.
