Understanding South Korea’s won-backed stablecoin debate
South Korea is weighing a fiat-backed stablecoin, balancing monetary sovereignty against the fact that global stablecoins are dominated by the U.S. dollar while domestic payments are already near-instant.
Thin domestic need despite sovereignty aims
The case for a won-pegged token is facing challenging headwinds. As a recent Korea Economic Daily report highlighted, skeptics argue the won's limited global demand and lack of reserve currency status would curb its adoption internationally. Domestically, the need is even less apparent. A study by NH Investment & Securities noted that with retail payments settling in seconds via biometrics or passwords, and with world-leading credit card and bank account penetration, the efficiency gains from a stablecoin are marginal at best.
Despite this, the appeal of digital currencies is growing. Transactions in dollar-backed stablecoins USDT and USDC on Korea’s five main exchanges totaled nearly $71 billion between January and August, according to CryptoQuant. This rising adoption presents both an opportunity and a threat. While some analysts believe stablecoins could smooth exchange-rate volatility, the Bank of Korea (BOK) has expressed concern.
In a recent working paper, Son Min-kyu of the central bank commented that the widespread use of dollar-backed stablecoins could entrench the dollar's dominance, while also amplifying run risk and market volatility in Treasuries during periods of stress.
Scarce short-term collateral
Seoul also faces a unique structural hurdle: a shortage of short-term government bonds to use as collateral. Unlike the U.S., where stablecoin issuers rely on a deep market for Treasury bills, Korea’s bond market is dominated by long-dated paper. Kim Pil-kyu of the Korea Capital Market Institute (KCMI) described short-term sovereign bills as vital for a stablecoin’s value preservation, a resource Korea currently lacks.
As South Korea deliberates, other major economies are forging ahead on divergent paths. Japan is moving to authorize privately issued stablecoins this fall, while the European Union has brought them under its comprehensive Markets in Crypto-Assets (MiCA) regulation.
UK’s cap plan clashes with pro-innovation push
This regulatory balancing act is also playing out in the U.K., where a policy rift is emerging. According to the Financial Times, the Bank of England has proposed capping individual holdings of widely used stablecoins at £10,000–£20,000, with a £10 million limit for businesses. Industry groups argue the plan would be expensive to implement and could blunt the U.K.’s competitive edge in digital finance. The central bank's caution also contrasts with the government's pro-innovation stance, with finance minister Rachel Reeves recently pledging to promote the use of stablecoins and tokenized securities.
For Seoul, the global shift toward tokenized money is undeniable. With seemingly limited domestic demand and various structural challenges, a won-backed stablecoin is, for now, an idea worth watching as the broader financial landscape evolves.
