In this study, we examined the effect of liquidity management on the performance of banks in Nigeria. Our sample comprised 18 banks included in the Nigerian Stock Exchange (NSE) from 2011 to 2017. Thus, the firm-year sample constitutes 90 (18 banks × 5 years) financial statements. We found that liquidity management positively and significantly affected banks’ profitability. Capital adequacy significantly affected return on assets, return on equity, and return on capital employed. Similarly, we found a significant positive effect of asset quality on the performance indicators. The analyses also showed that the liquidity ratio effect is positive and significant on the performance indicators. This result shows that banks with proper liquidity management will increase their profitability over time. This suggests that to increase the overall networth of shareholders, banks should place a strong emphasis on liquidity management. Thus, liquidity should be managed to minimise potential default risks.
