One of the central bank duties, which has been emphasized after the 2008 financial crisis, is maintaining financial stability and TBTF, "too big to fail", one of the important characteristics of financial institutions, has considerable effects on risky behaviors and thus financial instability. Due to the role of banks in the Iranian economy and the social sensitivities of their problems and the impact of disrupted financial stability on the economic security of society, this has significant importance in our country.
In this paper, the design of the banking system, as a systemically important financial platform (SIFP) based on Central Bank digital currency (CBDC), in order to improve financial stability by mitigating the "Too Big for Bankruptcy" (TBTF) problem, has been studied. In this design, the current banking systems and the strategic role of banks are replaced by a financial platform. To design such a platform, the current interaction between the central bank and banks and financial institutions has been studied using game theory, and by using the mechanism design approach, the platform has been changed to better control the TBTF issue and banks' risky behavior. In the suggested platform, information technologies related to the banking system, such as digital monies and in particular, CBDC, have been used to ensure the efficiency and security of the banking system. Finally, to resolve the TBTF problem, maintain the current system's functioning, and enhance financial stability, CBDC-based banking system considerations for controlling and regulating the financial system have been studied.
