The informal sector plays a vital role in the development of a modern economy. In Nigeria, the growth of informal financial institutions is a response to the inability of formal sectors like banks to meet the demands of rural areas lacking functional commercial banks. To bridge this gap, individuals formed cooperative societies in Makurdi Metropolis, pooling funds to address financial needs and promote economic empowerment. These informal financial institutions showcase the resilience and resourcefulness of individuals, contributing to economic growth and inclusivity. This study analyzed Cooperative Societies in the Socio-Economic Development of Makurdi metropolis; 1976 – 2019. The study adopted the historical approach in the course of sourcing materials. Materials were sourced from primary, secondary and tertiary sources. The primary sources included oral interviews with operators and members of cooperative societies in Makurdi Metropolis, and young and elderly people who are knowledgeable on the subject of research. This study adopted the Social Capital Theory and the Institutional Theory.

Social Capital Theory was applied to analyze the role of social connections within cooperative societies and their influence on economic development while the Institutional Theory was applied to analyze how formal and informal institutions influence the behaviour and outcomes of cooperative societies. The study found that cooperative societies as a form of informal financial arrangement bridges the gap that exists between the demand and supply of formal bank loan as supply leading economics in Makurdi metropolis. The study found that cooperatives are vital instruments for the socio-economic transformation of the area. However, they are constrained by a lot of impediments which had hindered their smooth functioning and this needs to be adequately tackled by government, members and management of these cooperatives.

The study concludes that there is advancement in saving habits of the people and this can be used as an avenue for the introduction of informal banking systems.

Cooperative societies inculcate good saving habits to its members which implies that it is not too late for Nigeria to commence a purpose-driven informal finance strategic fund to develop informal financial system through the cooperatives. The study recommends the provision of revolving credit to community members through their respective cooperative, and the integration of cooperatives into formal finance providers for the development and improvement of the economy.
