This article explores the critical role that International Financial Institutions (IFIs), specifically the International Monetary Fund (IMF) and the World Bank, have played in shaping Nigeria's development. Using Nigeria as a case study, the research investigates the impact of IMF and World Bank interventions on the country's economic policies, particularly through structural adjustment programs (SAPs) and development projects. The analysis includes a review of Nigeria’s economic challenges, beginning with its post-independence era, the introduction of SAPs in the 1980s, and the ongoing consequences of these reforms on economic stability, poverty reduction, and public services. The study also addresses the political and social responses to IFI-driven policies and evaluates both the successes and shortcomings of these interventions. Furthermore, the article highlights the lessons that other African nations can draw from Nigeria’s experience with IFIs, particularly in negotiating terms and managing long-term development goals. The future of Nigeria’s relationship with the IMF and World Bank is examined, with a focus on exploring alternative development partnerships and achieving greater economic independence.
