Public Financial Management Reforms and Budget Execution in Ogun State

This study evaluates the impact of public financial management (PFM) reforms on budget execution outcomes in Ogun State, located in Nigeria's South West geopolitical zone. Ogun State has implemented several PFM reform initiatives in the past five years, including the adoption of an Integrated Financial Management Information System (IFMIS) and a Treasury Single Account (TSA), providing a suitable case for evaluating reform effectiveness. Using a professional survey design supplemented by financial data analysis, data were collected from 160 budget officers, accountants, auditors, and financial controllers in the State Ministry of Finance and Office of the Accountant General. The Public Expenditure and Financial Accountability (PEFA) Framework guides the theoretical and analytical approach, offering a structured assessment of PFM system performance. Findings show that the adoption of IFMIS and TSA significantly improved cash management and reduced revenue leakages, yet budget execution rates for capital expenditure remain below 60 percent, driven by late procurement actions, contractor performance failures, and mid-year budget revisions. Internal audit functions have been strengthened but remain advisory rather than punitive. Recommendations include the introduction of rolling procurement plans, enhanced contract supervision protocols, and the empowerment of the state's Auditor General to take enforcement actions on financial irregularities. The findings contribute to the PFM reform literature relevant to Nigeria's sub-national governments.
