Abstract Purpose: The primary objective of this paper is to represent an econometric model based on market power and bank financing methods, analyzing and estimating the impact of these two variables while considering monetary policy as a moderating factor. In this process, achieving secondary objectives such as calculating the market power index, assessing the financing methods of selected banks, and determining an appropriate indicator for monetary policy is essential. Methodology: This study follows an independent paradigm introduction approach. A group of publicly traded banks was selected, and using annual financial statement data, the translog production function was estimated, followed by the calculation of the Lerner index for each bank. The monetary conditions index in this research was derived using a time-series regression model. The bank liquidity creation model was formulated based on the market power index, bank financing methods, and the monetary conditions index. The effect of each of these variables on liquidity creation was then measured. Findings: The results indicate no significant relationship between bank liquidity creation and non-deposit financing methods. However, a strong negative correlation exists between market power and liquidity creation, highlighting the need for banks to enhance market power and diversify revenue sources. Originality/Value: This is the first study in Iran that simultaneously examines the impact of financing methods, market power, and monetary policy on bank liquidity creation.
