Optimizing profitability through capital structure: An empirical analysis of Vietnamese commercial banks

Abstract

This study examines how the way Vietnamese commercial banks manage their money affects their profits. Vietnam's financial scene is changing quickly, and commercial banks are always trying to make more money. Capital structure, which includes things like debt and assets, is very important in this. This research looks closely at how different parts of capital structure affect a bank's profits. It uses data from 18 commercial banks in Vietnam that are listed on the stock market. The study uses the Generalized Least Squares (GLS) method, a detailed way of analyzing data. This method shows a clear link between capital structure—which includes debt ratio, growth rate, asset turnover, and asset size—and the profits of these banks. The results show how important capital structure is and suggest ways bank managers can improve profits by changing their capital structure. This can help make the banking sector in Vietnam stronger and more effective.
