The Korea Customs Service in 2022 uncovered a total of 15 cases of illegal foreign exchange transactions purposed for virtual asset speculation. These transactions were worth 5.6 trillion won (approximately $4.3 billion), local media Yonhap News Agency reported on Tuesday.

The cases are part of overall cases of trade and economy crimes traced by the customs service last year. Overall, illegal transactions flagged by the service shot up by more than half from the prior year to 8.2 trillion won ($6.2 billion).

Finance Magnates reported in July last year that South Korean watchdogs opened inquiries into ‘abnormal’ forex transactions worth $3.1 billion linked to crypto investments suspected of money laundering. The transactions were done at Woori Bank and Shinhan Bank, two of the biggest commercial banks in the country.

South Korea’s Financial Supervisory Service, a regulator under the Financial Services Commission (FSC), reported that moves like these made since February 2021 up until July last year were worth 4.1 trillion won ($3.1 billion). The transactions involved crypto exchanges and a domestic trading company, the watchdog said.

South Korea Cracks Down on Foreign Crypto Exchanges

Despite its small size, South Korea is one of the leading retail crypto markets globally as cryptocurrency penetration in the country is very high. However, since 2017, the country under its Foreign Exchange Transactions Act started requiring firms engaged in crypto transactions to get regulatory sanctioning from the FSC.

In August last year, South Korea cracked down on 16 overseas cryptocurrency exchanges operating in the country illegally. The platforms included big brands such as KuCoin and MEXC.

On the other hand, the Asian country recently started revising decades-old forex transaction rules under its Foreign Exchange Transactions Act. The revision follows public outcry against the limits of the set of policies. As part of the move, the country approved nine securities firms to engage in the business of currency exchange, serving both corporate and individual customers.

Furthermore, the country is making plans to open up its forex markets to offshore firms as well as extend their opening hours to 2am. Finance Magnates reported that these changes are to be implemented during the second half of 2024.
