South Korea Unveils $7.4 Billion in Illegal Forex Trades Linked to Tether Stablecoin

South Korean authorities have made a major breakthrough in uncovering illegal foreign exchange transactions linked to cryptocurrencies, with over $7.4 billion detected over the past five years. Tether (USDT), a stablecoin designed to maintain a 1:1 peg with the U.S. dollar, has played a central role in these illicit activities due to its stability and liquidity.

The value of detected illegal transactions has surged dramatically since 2021, with a more than fivefold increase in just one year. The number of reported cases also grew, indicating not only a rise in the volume of illicit flows but also an expanding pattern of abuse. Authorities note that the pseudonymous nature of blockchain transactions, combined with the stable value of USDT, makes it an attractive tool for circumventing South Korea's strict foreign exchange controls.

Industry experts point out that while stablecoins like Tether offer legitimate utility for trading and remittances, their misuse in illegal forex activities underscores the need for more robust compliance measures. Customs officials have indicated they are enhancing data-sharing agreements with crypto exchanges and employing advanced blockchain analytics to trace suspicious transactions.
