This study aims to ascertain the determinants affecting the liquidity of Vietnamese Commercial Banks by their bank ownership structures, CEO characteristics, and bank-specific variables. Using panel data consisting of 29 Vietnamese commercial banks, we measure liquidity using the most up-to-date method – the Net Stable Funding Difference (NSFD), according to Basel III standards. Correlating to the relationship between CEOs’ characteristics and bank liquidity, we found that CEOs with longer tenure will control liquidity better due to their higher managerial power and entrenchment. Moreover, the findings of the present study show that local market power, bank age, bank size, and loan loss provision positively impact bank liquidity. In contrast, further investigation reveals the adverse impact of state ownership on bank liquidity. This study provides insights into the prudential supervision of Vietnamese commercial banks, which implications for policymakers, by applying the latest liquidity measurement method and new findings on liquidity determinants.
