Stablecoin balances on South Korea’s five largest crypto exchanges have fallen 55% since July 2025, as traders shifted funds into stocks after the won weakened sharply against the dollar. Data from Allium Labs shows holdings dropped from $575 million in July to about $188 million by mid-March. The slide picked up after the won moved beyond 1,500 per dollar, a level last seen during the 2008 financial crisis.
Allium tracked Ethereum and Tron wallets linked to Upbit, Bithumb, Coinone, Korbit, and GOPAX. The data points to strong outflows as the won hit a 16-year low against the dollar. In turn, traders appear to have sold tether at favorable USD/KRW levels and converted the proceeds into won.
Bradley Park, founder of DNTV Research, said the weaker currency increased the appeal of exiting dollar-denominated holdings. From there, capital moved into local assets. The pattern suggests a direct response to foreign exchange moves rather than a wider retreat from risk.
The mid-March break above 1,500 won per dollar marked a key turning point. That threshold appears to have triggered a sharper round of stablecoin selling across South Korean exchanges. As the currency weakened, traders had a stronger reason to lock in gains on dollar-linked tokens.
This move came after an earlier shift from crypto into equities that CoinDesk documented in November. At that stage, retail traders had turned toward AI-linked chip stocks as momentum in altcoins faded. This time, the catalyst appears more specific.
Rather than following a fresh market narrative, traders reacted to the exchange rate. That difference matters because it suggests the latest outflows came from a currency-driven opportunity, not from a broad change in sentiment.
At the same time, South Korea’s government has stepped up efforts to draw money into domestic markets. One such measure includes repatriation accounts that offer up to 100% capital gains tax exemptions for investors who sell overseas assets and reinvest the proceeds at home.
Brokerage data reflects that shift. Investor deposits, which track cash available for stock purchases, fell from about 131 trillion won in early March to around 112 trillion won after the currency move. That drop suggests investors put cash to work in equities as stablecoin balances shrank.
Deposits have since started to stabilize. That trend suggests new inflows are rebuilding the pool of buying power. Meanwhile, stocks have continued to attract strong interest.

The KOSPI has climbed 75% in 2025 and added another 37% this year. That performance makes it the best-performing major index in the world. The rally remains heavily concentrated in Samsung Electronics and SK Hynix, which account for roughly half of the total market value and more than half of the projected profits.
That concentration makes both companies the main destination for retail and institutional flows. As money leaves stablecoins, much of it appears to be landing in those large-cap names.
Across Asia, the picture looks different. Artemis data shows stablecoin transaction volumes have increased over the past year. That contrast suggests South Korea’s decline reflects a local capital rotation, not a regional pullback from crypto.
South Korea has long served as a major source of retail-driven crypto liquidity. For now, that liquidity has moved into equities. If the stock rally weakens, could that money move back into crypto just as fast?
South Korea's stablecoin balances fell sharply as the weaker Korean won pushed traders to exit dollar-linked crypto holdings and move funds into equities. With the KOSPI attracting strong inflows, the shift shows capital has changed direction, not disappeared. Market watchers will now track whether stock momentum holds.
