Stablecoin balances in South Korea have fallen sharply since July even as equity inflows rise, underscoring a shift in money flow.
The total amount of these so-called tokenized versions of fiat currencies held in wallets linked to South Korea’s five largest cryptocurrency exchanges has plunged 55%, and on-chain data points to a sharp wave of outflows triggered by the won’s breakout beyond 1,500 per dollar in mid-March.
Data from Allium Labs, which tracks Ethereum and Tron wallets on Upbit, Bithumb, Coinone, Korbit and GOPAX, shows that combined stablecoin holdings fell from $575 million in July 2025 to about $188 million in mid-March, with the decline accelerating as the won fell to 16-year lows against the dollar.
The timing suggests that traders sold Tether at elevated USD/KRW levels after the won weakened beyond 1,500 per dollar in mid-March, a threshold not seen since the 2008 financial crisis.
The weaker currency amplified the incentive to exit dollar-denominated holdings, with traders converting them into won and redistributing them into domestic assets, according to DNTV Research founder Bradley Park.
The exits mark the latest phase of a broader migration of Korean retail capital from cryptocurrencies to stocks, a shift CoinDesk first documented in November. But while that earlier rotation was largely narrative-driven, with traders chasing AI-linked chipmakers as altcoin momentum faded, the latest drop appears to be tied to a specific currency trigger rather than a change in risk appetite.
Since then, the South Korean government has stepped up efforts to attract capital to domestic markets through new policies such as “repatriation” accounts that offer up to 100% capital gains tax exemptions for investors who sell assets abroad and reinvest locally.
That change is visible in the brokerage data. Investor deposits, a proxy for cash available to buy stocks, fell from about ₩131 trillion ($86 billion) in early March to about ₩112 trillion ($74 billion) following the mid-month currency move, indicating capital was being actively deployed into stocks as stablecoin balances declined. Deposits have since begun to stabilize, suggesting that new capital inflows are replenishing purchasing power.
The KOSPI, which is already up 75% in 2025, has gained another 37% this year, making it the best-performing major index in the world. The rally is highly concentrated: Samsung Electronics and SK Hynix represent approximately half of the market capitalization and more than 50% of projected profits, positioning them as the main destination for both retail and institutional flows.
Broader stablecoin trading volumes across Asia have increased over the past year, according to Artemis data, suggesting the decline on Korean exchanges reflects domestic capital turnover rather than a region-wide pullback.
For crypto markets, the change underscores the loss of one of its most important retail liquidity pools.
Korean participation has historically amplified market cycles, and data now shows that capital is not idle but is being actively redeployed. Whether those flows return may depend less on crypto narratives than on the sustainability of Korea’s stock rally.
A sharp correction, particularly in a market so concentrated in semiconductor stocks, could quickly force capital to rotate again. KOSPI has been under pressure recently as disruptions to oil transit through the Strait of Hormuz have raised concerns about energy supplies.
