The purpose of this study is to prevent financial corruption in the banking system. Cases where criminal law is related to banking crimes and violations can be examined in two categories: the system for preventing banking crimes and violations and the criminal system for criminals and violations. Banking corporate governance is a set of relationships between supervisory institutions, shareholders, managers and auditors of the bank, which involves establishing a control system in order to observe the rights of minority shareholders and properly implement the resolutions of the assembly and prevent possible abuses. These regulations, which are based on a specific legal system and social responsibility, are a set of duties and responsibilities that must be accepted by the bank's organs in order to ensure accountability and transparency. The results of this study, which was conducted using a descriptive-analytical method, indicate that the country's legal system, except in a few cases, has a fundamental gap in terms of specific banking crimes and the provision of a specific criminal system for their punishment; So that most of the recorded banking crimes are general financial crimes that can occur in the banking context. Strengthening the governance of the banking company and the country's recorded system of laws and regulations on banking crimes and violations is essential.
