Commercial banks in Vietnam are working to meet capital adequacy standards set by Basel. A study looked at factors influencing this from 2007-2018. They found that return on equity and bank size have opposite effects on capital adequacy. Return on assets, customer deposits, credit risk, and liquidity all impact capital adequacy in a similar way. Additionally, inflation rates positively affect capital adequacy for Vietnamese banks. To meet Basel standards, Vietnamese banks need to focus on internal factors and improve their performance.
