This study examines banking fraud and its effects on the Nigerian economy, focusing on selected deposit money banks: Ecobank, Union Bank, Skye Bank, Keystone Bank, Stanbic IBTC, and United Bank for Africa (UBA). Fraud has become pervasive in Nigerian banking, with fraudsters continually devising new methods to circumvent detection measures, often in collaboration with dishonest bank staff. Adopting an ex post facto research design, the study analyses time-series data from 2011 to 2024 using multiple linear regression. The dependent variable is GDP growth rate per capita, while independent variables include bank credit to the private sector, growth in liquid liabilities, and net interest margin. Findings reveal that bank credit exerts a positive and significant impact on economic growth in Nigeria. Similarly, growth in banks' liquid liabilities and net interest margins positively and significantly influence economic expansion. The study concludes that banking operations have contributed favourably to Nigeria's economic growth, though fraud remains a threat to public confidence and financial stability. It recommends directing credit to priority sectors such as manufacturing and agriculture, and that government legislation encourage private-sector financing through targeted incentives and a stable macroeconomic environment.
