Competition over digital currency sovereignty is intensifying globally and in South Korea as the United States moves to bring dollar-based stablecoins into the mainstream and other regions press ahead with regulation. In South Korea, legislation for a won stablecoin is delayed by disagreements over issuers, reserve requirements and oversight. Banks and fintech firms are already moving to secure payment infrastructure. U.S. crypto legislation has also stirred markets, lifting interest in some altcoins while bitcoin swings on geopolitical tensions.

Tether, the world’s largest stablecoin issuer, has filed multiple trademark applications in South Korea, including for its corporate brand and gold-linked stablecoin Tether Gold (XAUT). The move comes as discussions advance on tightening stablecoin rules, including possible requirements for foreign issuers to set up local branches. Rival Circle has also stepped up outreach in Korea and expanded platform partnerships. The domestic market is seen as large, though the regulatory framework is still unsettled.
