The purpose of this study is to examine the role of domestic laws and international requirements in combating banking corruption. In the Iranian banking system, the existence of corruption has always been challenging due to legal, regulatory, and structural weaknesses. Therefore, effectively combating this phenomenon requires a comprehensive approach that includes amending domestic laws, adapting them to international standards, strengthening corporate governance, and transparency in the banking system. In this study, in addition to examining the concept of banking corruption and its types, the role of domestic laws and adherence to international treaties in combating this type of corruption has been analyzed. Also, the negative effects of banking corruption on financial stability, public trust, and social justice have been examined, and the pathology of existing legislation and failure to comply with international requirements have been raised. The findings of the study, which was conducted using a descriptive-analytical method, show that the Iranian banking regulatory system has weaknesses, including conflicting laws, inefficiency in accurate execution, non-compliance with international standards, and lack of technical and supervisory infrastructure. Only with an integrated and coordinated approach at the domestic and international levels can achieve reduction in corruption, increase financial stability, and gain public and international trust in the Iranian banking system.
