South Korea’s central bank digital currency (CBDC) project has revealed oversight loopholes. The Bank of Korea’s inaugural pilot, known as Project Han River, took place from April to June last year. However, the trial was conducted without any independent government security inspections. This was revealed in Financial Supervisory Service (FSS) documents submitted to lawmaker Lee Heon-seung and published by the Maeil Business newspaper.
During the preparatory phase, security evaluations conducted before the pilot launched in February were limited to IT security reviews and vulnerability assessments. These evaluations were partially delegated to internal teams from participating banks, namely Woori Bank and NongHyup Bank, who worked alongside the Financial Security Institute and SK Shields to inspect the system.
This practice placed participating institutions in a dual role: operating the new system while simultaneously assessing the security of the infrastructure being tested. The situation has raised concerns over potential conflicts of interest that disregard the principles of independent oversight.
No Follow-Up Evaluations
Following the conclusion of the pilot period, there was no sign of independent supervisory involvement. The report highlighted the absence of external audits or post-pilot inspections by neutral government agencies. The Bank of Korea dismissed these concerns, arguing that a comprehensive review had already been completed before the pilot began, rendering additional inspections at the end of the phase unnecessary.
The lack of external oversight mirrors the slow pace of banking sector adaptation. Over the past three years, there has been only one formal consultation between a banking institution and regulators regarding CBDC products. That single consultation involved Shinhan Bank discussing insurance products. To date, South Korean banks have yet to establish dedicated teams to oversee CBDC operations.
The situation has drawn criticism. An industry official, speaking on condition of anonymity, emphasized that independent security verification is essential. They noted that post-pilot external audits are an indispensable requirement to build market confidence in the new financial system.
A Broader Agenda Moves Forward
Despite the absence of independent audits, South Korea’s digital asset agenda continues to push forward. In July 2026, a joint roadmap was released by the FSC, the Bank of Korea, the FSS, and the Korea Securities Depository to establish the won as a freely convertible currency, accompanied by won-backed stablecoin regulations.
This expansion has also reached local governments. Gyeonggi Province announced the launch of the first local government-backed blockchain stablecoin pilot, scheduled to run from August through February 2027. On a global scale, South Korea is also preparing to participate in the Bank for International Settlements (BIS) Project Agora for cross-border payment infrastructure.
While national innovation trials require speed, overlooking the role of third parties leaves critical gaps. Public trust in new infrastructure is difficult to build when the entities responsible for grading the security exams are the test participants themselves.
