The aim of this study was to investigate the effects of the features of monetary governance of banks on capital management in active private businesses. The features of monetary governance of banks used in this study include the board size, the board effectiveness, equity, and audit performance transparency. The 5-year mean of the effective capital rate was used in order to measure the capital management more accurately. The data were extracted from active private banks during the period from 2016 to 2022. The data analysis and hypotheses tests were performed using the multivariate regression model. According to the results of the research hypotheses test, there was no significant relationship between the board size and the capital management. In other words, in Iran, the board size does not influence the capital management. Also, the results showed that there is a significant negative relationship between the board composition and the effective capital rate. The other research findings indicate a significant positive relationship between the effective capital rate and the equity. In addition, there is a significant positive relationship between the audit performance transparency and the capital management.
