The relevance of the capital structure to value maximization is a subject that still causes controversy. Due to legal restrictions and controls on liabilities, there are still discussions about the ability of banks to create value from their capital structure. As public or private entities for profit, banks play a decisive role in the functioning of countries' economic systems and development. The way they fund raising their capital structure can significantly affect their results. Generally, these institutions enable a greater participation of debt in the capital structure, especially higher levels of customer deposits, as it is considered one of the least costly forms of funding, thus creating ideal conditions for leverage results. The importance of these companies to the society, capital market and economy of the country, are some aspects that justify the development of studies in the banking sector. Therefore, this research seeks to verify the capital structure relevance for the maximization of value in the four largest publicly traded banks in Brazil and to identify the main determinants of the profitability of these companies. The data collected for the research are longitudinal, obtained from the Economatica® database, and include the period between the first quarter of 2008 and the first quarter of 2018. To represent the variables analyzed in the research, economic-financial indicators were calculated based on the consolidated financial statements disclosed for the period. The research is descriptive, of quantitative approach, using descriptive statistics, correlation tests and linear regression models with panel data (pooled, fixed effects and random effects). The main statistically significant results obtained with the research indicate the relevance of the capital structure - represented by Leverage (LEV) and Capitalization (CAP) variables - for bank profitability measured by ROA (Return on Assets), ROE (Return on Equity) and ROICADJUSTED (Return on Invested Capital Adjusted). Variables related to banking strategies (operational efficiency, solvency and liquidity) were also statistically significant for the profitability of the largest publicly traded banks in Brazil. The research contributes academically to the academic debate on the relevance of the capital structure for the maximization of value in the banks and to identify the main determinants of the profitability of these companies. In the social sphere, it contributes to the decision-making process of managers, investors, financial analysts and regulators of the sector by addressing aspects that encourage banks to maintain high levels of leverage in their capital structure, highlighting the risks and costs involved
