This study explores the impact of strategy implementation on the performance of regulatory agencies in Nigeria's financial services sector. Addressing key challenges such as fragility, transparency, consumer protection, financial crime prevention, and resource allocation, it examines the roles of the Central Bank of Nigeria (CBN), Nigeria Deposit Insurance Corporation (NDIC), Securities and Exchange Commission (SEC), and National Insurance Commission (NAICOM). Data from 342 staff members were analyzed using descriptive statistics and multiple regression. Results show that technology adoption, strategic leadership, communication, resource availability, optimized organizational structures, and inter-agency alignment significantly influence performance. The study underscores the importance of effective strategy implementation, recommending the adoption of advanced technologies like RegTech, big data, and cybersecurity, alongside strong leadership, transparent communication, and adequate funding to enhance regulatory performance and ensure accountability in Nigeria's financial sector.
