South Korea crypto liquidity tumbles as stablecoin balances plunge 55% and stock heat up

Stablecoin balances in South Korea have fallen sharply since July even as stock inflows rise, underscoring a shift in where money is flowing.

The total amount of these so-called tokenized versions of fiat currencies held in wallets tied to South Korea’s five largest crypto exchanges have plunged 55%, with on-chain data pointing to a sharp wave of outflows triggered by the won’s break past 1,500 per dollar in mid-March.

Data from Allium Labs, tracking Ethereum and Tron wallets across Upbit, Bithumb, Coinone, Korbit, and GOPAX, shows that combined stablecoin holdings dropped from $575 million in July 2025 to roughly $188 million as of mid-March, with the decline accelerating as the won slid to 16-year lows against the dollar.

The timing suggests traders sold tether at elevated USD/KRW levels after the won weakened past 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 into won and redeploying into domestic assets, according to DNTV Research founder Bradley Park.

The outflows mark the latest phase of a broader migration of Korean retail capital from crypto into equities, a shift CoinDesk first documented in November. But where that earlier rotation was driven largely by narrative, with traders chasing AI-linked chipmakers as altcoin momentum faded, the latest drawdown appears tied to a specific FX trigger rather than a change in risk appetite.

South Korea’s government has since intensified efforts to attract capital into domestic markets through new policies such as “repatriation” accounts that offer up to 100% capital gains tax exemptions for investors who sell overseas assets and reinvest locally.

That shift is visible in brokerage data. Investor deposits, a proxy for cash available to buy stocks, fell from roughly ₩131 trillion ($86 billion) in early March to around ₩112 trillion ($74 billion) following the mid-month currency move, indicating that capital was being actively deployed into equities as stablecoin balances declined. Deposits have since begun to stabilize, suggesting fresh inflows are replenishing the pool of buying power.

The KOSPI, already up 75% in 2025, has gained another 37% this year, making it the world’s best-performing major index. The rally is highly concentrated, with Samsung Electronics and SK Hynix accounting for roughly half of market capitalization and more than 50% of projected profits, positioning them as the primary destination for both retail and institutional flows.

Broader stablecoin transaction volumes across Asia have ticked up over the last year, according to data from Artemis, suggesting the drawdown on Korean exchanges reflects domestic capital rotation rather than a region-wide pullback.

For crypto markets, the shift underscores the loss of one of their most important retail liquidity pools.

Korean participation has historically amplified market cycles, and the data now shows capital is not sitting idle but being actively redeployed. Whether those flows return may depend less on crypto narratives than on the sustainability of Korea’s equity rally.

A sharp correction, particularly in a market so concentrated in semiconductor stocks, could quickly force capital to rotate again. KOSPI has come under pressure recently as disruptions in oil transits through the Strait of Hormuz has sparked energy supply concerns.
