Key Highlights
- South Korea busts crypto laundering ring moving 150B won through illegal foreign exchange schemes.
- Three Chinese nationals indicted by KCS for violating South Korea’s foreign exchange laws.
- Laundered funds disguised as cosmetic surgery and study abroad payments to evade regulators.
South Korean customs authorities have uncovered an international crime group accused of laundering 150 billion won (US$101.7 million) in cryptocurrencies.
According to a local report, the suspects allegedly employed an illegal foreign exchange scheme to move the funds across borders without any trace. The case conducted by the Korea Customs Service (KCS) has indicted three Chinese nationals for violating the foreign exchange laws of South Korea.
As reported by KCS, nearly 149 billion won was transferred from September 2021 to June 2025 by the suspects through domestic and international crypto accounts and South Korean bank accounts.
Authorities said the funds were disguised to appear as normal transactions, such as cosmetic surgery fees for foreigners or educational costs for students studying abroad. By so doing, it appears that the suspects managed to evade detection by financial regulatory agencies.
The suspects allegedly purchased cryptocurrency in several different countries and exchanged it for South Korean digital currency. They then converted it into Korean won, moving the money through a variety of domestic bank accounts. Authorities have described this as a “complex laundering network.”
This case also underscores the challenges in regulating international transactions related to cryptocurrency. As the usage of digital money is becoming increasingly common, government authorities worldwide are finding it difficult to curb its usage for money laundering purposes.
KCS said the investigation is ongoing and could uncover more suspects and details.
South Korea’s crypto regulation updates
In recent months, South Korea has moved quickly to regulate cryptocurrency. Starting January 28, Google Play will block foreign crypto apps that don’t have local VASP registration, giving an advantage to domestic exchanges like Upbit and Bithumb.
It has also removed a nine-year ban on corporate cryptocurrency investment, enabling listed companies and professional investors to invest up to 5% of their equity into the top 20 cryptocurrencies.
Moreover, South Korea’s Financial Intelligence Unit (FIU) has reported a sharp rise in illicit cryptocurrency activity. From January to August 2025, virtual asset service providers filed a record 36,684 suspicious transaction reports (STRs), more than the total of the previous two years combined.
Right now, the main focus is on regulating stablecoins, with new rules on issuer approval, asset reserves, and cross-border transactions. These changes aim to attract institutional investors, reduce risky speculation, and make cryptocurrency markets more transparent and regulated.
