In recent years, fintech has revolutionized the financial industry by utilizing advanced technologies like blockchain, AI, and big data to enhance the speed, cost-effectiveness, and user-friendliness of financial services. A key area impacted by fintech is liquidity efficiency in financial markets.

In this research, for measuring fintech development, the research model of Tang et al (2024) was used, and for measuring liquidity efficiency, two indicators of net stable funding ratio and financial leverage were utilized. In the present research, all banks listed on the Tehran Stock Exchange were considered as the statistical population, and among them, 21 banks were selected as the statistical sample, in the time period from the years 2013 to 2024 based on the characteristics of the research. For testing the research hypotheses, the panel data method was used. Findings showed that the development of fintech has a positive and significant impact on two liquidity efficiency indicators (net stable funding ratio and financial leverage).

In general, the present research has developed the literature related to the development of financial technology (fintech) on liquidity efficiency and has provided evidence regarding the impact of fintech on two liquidity efficiency indicators (net stable funding ratio and financial leverage). The results of this research show that fintech not only increases liquidity efficiency but also leads to fundamental changes in the management of financial resources by institutions and will pave the way for strategic decision-making by managers in adopting these technologies.
