The study examines the effect of leverage and capital on the profitability of selected Saudi Arabian Banks during the period 2014 and 2019. The banks have been selected based upon their size in terms of total assets. The profitability elements, such as Earnings per Share (EPS), Return on Assets (ROA), and Return on Equity (ROE) are the dependent variables; Total Debt Ratio (TDR), Tier 1 Capital Ratio (Tier 1 CAP), and Debt to Equity Ratio (DE) are the independent variables, and firm size is the control variable. The study estimates a pooled regression analysis to analyze the effect of these variables. The results of the study show that there is a positive relationship between the different profitability variables and Debt to Equity Ratio. The Total Debt Ratio is having positive association with ROA and ROE, and has an insignificant negative relationship with the EPS, and the Tier 1 capital ratio is having positive association with ROA and ROE, and has an insignificant relationship with the EPS.

In this paper, we attempt to answer the question of whether or not bank capital affects profitability and risk. The paper forms an unbalanced panel with 354 observations using both data of 35 banks over the period 2007-2018. Two-step GMM is used to estimate the impacts of bank capital on profitability and risk in order to eliminate endogeneity and serial correlation issues. As a proxy of bank capital, the bank equity ratio, and equity level are used. Return on assets (ROA), return on equities (ROE), and net interest margin (NIM) are used to measure bank profitability, whereas nonperforming loan ratio and loan loss reserve ratio are used to measure bank risk. Bank capital displays significant impacts on profitability, which is measured by ROA and ROE, whereas capital shows no impact on bank NIM. When the loan loss reserve ratio is considered as proxy of bank risk, bank capital does not affect bank risk. The equity ratio, the proxy of bank capital, displays significant negative impacts on risk, whereas the equity level, the other proxy of bank capital, shows positive impacts on bank risk.
