The study specifically investigated the impact of sub-national government sovereign wealth funds on the economic development of Nigeria. An ex-post research design was used for the study. Economic development was proxied by per capita income, while sovereign wealth funds were proxied by their three components: stabilization funds, future generation funds, and infrastructure funds. Data for the variables were obtained from the Central Bank of Nigeria for the period 2012–2022. An econometric approach was used to analyze the data. Findings showed that of the three components of SWFs, only future generation funds impact positively and significantly on economic development. In view of the findings, it is recommended that the government ensure effective and efficient management of the various funds by putting in place proper regulatory measures so as to attain the goals for which the funds were established.
