South Korea stablecoin trading surges 62%

TLDR

Stablecoin trading on South Korean exchanges has jumped about 62% as the won weakens, showing locals increasingly using dollar-pegged tokens as a currency hedge and liquidity parking tool.

1. Stablecoin volumes across Koreas top won-based exchanges spiked 62%, reaching about 378.2 billion KRW (around 261 million USD) on a recent high-volatility day.
2. The move is tied to a weakening won, collapsing dollar-deposit rates at banks, and aggressive exchange promotions around stablecoins like USDC and USDe.
3. Rising stablecoin use could deepen local crypto liquidity but also invites tighter regulation, including upcoming rules on won-pegged stablecoins and exchange-bank relationships.

Deep Dive

1. Size Of The Spike

Crypto market data provider CryptoQuant reports a 62% surge in stablecoin trading volumes on South Koreas five major won-based exchanges as the won fell to multi-year lows versus the dollar, with daily stablecoin volume hitting about 378.2 billion KRW (around 261 million USD) when USD/KRW traded above 1,480 to 1. This jump in volume followed nine straight days of won declines, the longest losing streak since 2008.

The activity is concentrated on large local platforms such as Upbit, Bithumb, Coinone and Korbit, which already dominate Korean won trading in crypto. Exchanges specifically highlighted stablecoins like USDC and USDe in their campaigns.

2. Why Koreans Are Turning To Stablecoins

Banks in South Korea, under government pressure to stabilize the currency, have slashed interest rates on dollar deposits toward zero, with large banks cutting typical rates from around 1.52.0% to roughly 0.050.1% while offering bonuses to move funds back into won. At the same time, dollar deposit balances at the top five banks fell about 3.8% to roughly 63.25 billion USD, suggesting less appeal in holding dollars via the traditional banking channel.

Stablecoins offer a pseudo-dollar exposure without going through bank FX products, and exchanges sweetened that further by waiving fees and offering rewards for stablecoin trading during this period. In a weakening currency environment, a relatively stable, liquid dollar token can look more attractive than volatile coins or low-yield bank deposits.

3. Structural Shifts And Regulation To Watch

Regulators are already reviewing the one exchange one bank model that ties each crypto exchange to a single banking partner, citing concerns about concentration and fairness as they study broader market structure and competition. This review coincides with work on the Digital Asset Basic Act, which is expected to enable regulated won-pegged stablecoins and set clearer supervision of stablecoin issuers in the next regulatory phase, as outlined in a recent policy review.

At the same time, South Korea is tightening anti-money laundering enforcement around cross-border crypto flows, which could eventually affect how easily locals move between bank FX, offshore exchanges, and onshore stablecoins. If stablecoin volumes stay high, policymakers may see them as both a pressure valve for FX risk and a channel they want more direct control over.

Conclusion

South Koreas 62% jump in stablecoin trading is less about speculative mania and more about locals using crypto rails to navigate a weak currency and unattractive bank dollar products. If FX pressure and macro uncertainty persist, stablecoins are likely to stay central to Korean crypto activity, while regulators move to formalize and constrain that role through new rules on stablecoins, exchanges and bank partnerships.
