Shares of leading South Korean banks jumped sharply after filing trademark applications for stablecoins, highlighting rising institutional interest in digital assets.
Data from Google Finance shows that at least three banks that recently sought trademarks for Korean won-pegged stablecoins saw their stock prices climb between 10% and nearly 20%. The surge reflects growing investor confidence in the banks’ potential move into the cryptocurrency space.
The trademark filings came soon after the June 4 inauguration of South Korea’s 21st president, Lee Jae‑myung, who campaigned on a crypto-friendly platform that included plans for a Korean won-backed stablecoin.
