This study was investigated the governance structure of financial safety net system, thereafter global financial crisis, which a discussion for reorganization of the financial safety net is ongoing, especially focusing on the improvement of the governance structure in Korea Deposit Insurance Corporation(KDIC). Through the process of overcoming the recent global financial crisis, it is recognized that only supervisory authority is limited for the stability of financial markets, and then that the active role of the Deposit Insurance System, as the axis of the financial safety net, is more necessary. This study suggests that it is necessary of improving the governance of financial safety net organizations as a prerequisite for building a desirable system of financial safety net. Despite of the organizations, as being mutually independent, have cooperative relationships through a mechanism of checks and balances, the governance of KDIC is deferent from the other’s, respectively. These differences are perhaps underlying why KDIC is appointed as a Fund- Managerial-type Quasi-Governmental organization on the operation law of the public authorities. So KDIC, as specified in accordance with the public organizations, does not have equal status with other financial safety net organizations, which can be easily exposed to impacts from the outside. And then, KDIC, due to specify public authorities, organizes a separate board of directors, so its mission and role are overlapped Deposit Insurance Commission’s, as the highest decision- making body, therefore it should be improved. Futhermore, this paper provides a policy implications timely, because there are efforts in order to enhance or strengthen the effectiveness and role of deposit insurance systems.
