This study examines the impact of financial technology on the performance of commercial banks in Nigeria, using return on assets (ROA) as a proxy for banking sector performance. A financial time series research design was adopted, covering a sample of five selected quoted commercial banks over the period 2009–2023. Data were sourced from financial statements, the Central Bank of Nigeria (CBN) statistical bulletins, and the Nigeria Deposit Insurance Corporation (NDIC) reports. The study employed the Ordinary Least Squares (OLS) regression technique to estimate the effect of key financial technology indicators Point of Sale (POS) transactions, Automated Teller Machine (ATM) transactions, Mobile Banking (MBB), and Internet Banking (ITB) on banking performance. The results indicate that ATM, MBB, and ITB usage significantly enhance bank profitability, while POS transactions have a positive but relatively lower impact. The findings suggest that digital banking adoption is a crucial driver of financial performance in Nigeria. The study recommends increased investment in digital banking infrastructure to further optimize bank profitability and financial inclusion.
