The Bank of Korea has launched its first reported survey examining how banks and securities firms could be affected by major cryptocurrency-related incidents, including exchange hacks, sharp market crashes, and significant losses at other financial institutions. The review reflects growing concerns about the potential links between South Korea’s traditional financial system and the digital asset market.
The central bank began surveying 18 banks and 13 brokerages on October 23, asking about their cryptocurrency-related operations, staffing, budgets, investment activities, and reasons for entering the sector. Financial institutions are also being asked to disclose their exposure to domestic and international cryptocurrency companies.
One of the survey’s key scenarios examines the potential impact of a major cyberattack that forces South Korea’s largest cryptocurrency exchange by market share to temporarily suspend operations. Other questions focus on the consequences of a steep decline in cryptocurrency prices followed by prolonged trading weakness, as well as the possibility that losses at another financial institution could spread through crypto-related exposures.
Although the survey began before last week’s reported $6.3 billion Binance hack, the incident highlights the type of cybersecurity and financial risks the central bank is attempting to assess. U.S. authorities have attributed the attack to North Korean hackers, adding to concerns about the vulnerability of digital asset infrastructure.
The review comes as South Korean financial institutions continue exploring opportunities in the stablecoin and digital asset sectors. KB Financial Group completed a pilot project involving a Korean won-denominated stablecoin in May, while Kakao Pay and KakaoBank partnered with Fireblocks in September to explore digital asset infrastructure. These initiatives suggest that traditional financial institutions remain interested in expanding their role in the crypto economy despite regulatory uncertainty.
However, disagreements over which institutions should be allowed to issue stablecoins have slowed progress on South Korea’s proposed Digital Asset Basic Act. The Bank of Korea has advocated a bank-led approach to stablecoin issuance, while other stakeholders continue debating the regulatory framework. At the same time, financial regulators are increasing cybersecurity oversight, with proposed measures that include more frequent vulnerability assessments and greater executive accountability.
The survey signals that South Korean authorities are increasingly focused on understanding how cryptocurrency-related disruptions could affect the broader financial system. For crypto markets, stronger oversight could improve institutional risk management and support long-term confidence, but stricter requirements may also increase compliance costs and create additional hurdles for companies seeking to expand their operations.
