South Korea's Financial Supervisory Service, Customs Service, and credit card companies have formed a coalition to tackle cryptocurrency-related financial crimes. The initiative, formalized through a "Public-Private Partnership Agreement to Block Transnational Criminal Funds," aims to disrupt funding channels for telephone fraud and virtual asset crimes by scrutinizing overseas credit card transactions and immigration records. Under this new framework, the Korea Customs Service will share high-risk transaction data with credit card companies, enabling real-time monitoring of suspicious overseas spending. The Financial Supervisory Service will provide guidelines allowing credit card companies to suspend transactions upon detecting anomalies. This system targets illicit "currency exchange" activities, including overseas ATM cash withdrawals and money laundering via cryptocurrencies, marking a significant step in preventing the outflow of criminal proceeds from South Korea.
