This study investigates the effect of Non-Performing Loans (NPLs) and Capital Adequacy on the
stability of commercial banks in Nigeria. Utilizing a quantitative research approach, the study
focused on eight (8) commercial banks with international authorization listed on the Nigerian
Stock Exchange as of December 2022, representing a stratified sample of licensed deposit money
banks in the country. Both descriptive and inferential statistical techniques were employed in
analyzing the data, with STATA software used for inferential analysis. The findings reveal that
Non-Performing Loans have a negative but statistically insignificant impact on bank stability,
while Capital Adequacy has a positive and statistically significant effect. Based on these findings,
the study recommends that bank management should ensure accurate classification and reporting
of loan portfolios, in line with established accounting principles. Furthermore, it emphasizes the
importance of maintaining an adequate capital base to enhance resilience against market risks,
ensure liquidity, and protect against insolvency. These measures are essential for sustaining the
financial health and operational efficiency of commercial banks in Nigeria.
