Regional Analysis

Access to Korea's financial payment system was restricted, necessitating a distinct contract with each bank in order to obtain full system access. In addition, excessive fees imposed on fintech companies made it difficult for them to release and operate innovative services.

Based on the "essential facility doctrine," which requires the owner to allow competitors access and use of the essential facility in order to increase competition among essential facility owners while maximizing consumer benefits, the Financial Services Commission (FSC) sought means to ensure fair access and use of payment networks where a natural monopoly exists.

Open banking is a joint open infrastructure in the banking sector that operates core financial services in a standardized open API to offer fintech services to consumers at a reasonable price without requiring banks and fintech firms to form partnerships. Six APIs provide core financial services such as inquiry and transmission.
