KCS Says Illegal Forex Transactions for Crypto Purchases Amount to $7.7B
Over the past five years, the total value of illegal foreign exchange transactions associated with virtual asset purchases has amounted to approximately KRW 10.4 trillion ($7.7 billion), according to the Korea Customs Service’s report received on Thursday by Go Yong-jin, a member of the Democratic Party of Korea on the National Assembly’s Strategy and Finance Committee.

“Illegal transactions on foreign exchanges for the purchase of virtual assets are occurring due to the higher prices of virtual assets in Korea compared to prices abroad,” Go explained.
Crimes incited by crypto wave
The data showed that the number of violations subject to fines was 6,066, involving forex transactions of KRW 2.3 trillion. In particular, violations made in 2020 and 2022 accounted for the majority, making up 78.7% with 4,775 cases and a value of KRW 1.9 trillion, or 83.7% of the cumulative total. This indicates a substantial increase in illegal activities during the periods when the crypto investment frenzy in Korea was at its peak.
Uncovering key patterns
While foreign exchange transactions were primarily intended for acquiring virtual assets, they were often disguised as trade payments. There were also cases where individuals withdrew foreign currency from overseas ATMs to buy cryptocurrencies. These two scenarios were the most prevalent cases for which fines were imposed. More specifically, among the 6,066 violations, there were 4,518 instances of the former and 1,486 cases of the latter. The transferred funds amounted to KRW 1.9 trillion and KRW 407 billion, respectively.
During the five-year period, individuals involved in 93 cases of these forex activities — collectively valued at KRW 8.1 trillion — were penalized following the referral of their cases to prosecutors. In particular, the violations in 2022 accounted for 70.3% (KRW 5.7 trillion). This could be accredited to the breakout of suspicious large-scale forex transactions last year, which prompted local authorities such as the Korea Customs Service and the Financial Supervisory Service (FSS) to initiate planned investigations.
The most common type of illegal foreign exchange transaction cases referred to prosecutors was similar to those that incurred fines: overseas remittances disguised as trade payments, constituting 49.9% (KRW 4 trillion) of all cases. Transferring foreign currency via unregistered entities was the second most common violation, making up 47.2% (KRW 3.8 trillion). These transfers breach the Foreign Exchange Transactions Act and are always reported to prosecutors.
Go thereby called on authorities to intensify crackdowns on illegal forex transactions aimed at trading virtual assets and to revise foreign exchange regulations accordingly.
