SUMMARY
Abstract –The capital structure in banking has become discussed due to the competition with the fintech and bank digital and debate about the efficiency of its choices. The purpose of this paper is to investigate the dynamics that go into determining a bank's capital structure in Indonesia. The capital structure of Indonesian banks is examined using a panel regression model. Profitability, corporate tax, growth, collateral, and bank size all influence banks' financing or capital structure decisions, according to the findings of this study. The study's most important result is that debts finance more than 87 percent of banks' assets, with short-term obligations accounting for more than three-quarters of bank capital. This emphasizes the importance of short-term borrowing in Indonesian bank funding over long-term debts. The fundamental contribution of this article is the identification of factors that influence the capital structure of Indonesian banks.Keywords: Capital Structure Determinants; Banks; Trade-Off Theory; Pecking Order Theory
