South Korea Delays 20% Crypto Tax Until 2027 Amid $110 Billion Capital Flight Crisis
SEOUL, March 25, 2026 – South Korean lawmakers have made a dramatic U-turn, agreeing to postpone the nation's contentious 20% crypto gains tax until 2027 following data revealing a staggering $110 billion in annual capital flight. The bipartisan reversal comes as a direct response to a retail exodus that has drained domestic exchange liquidity, with the Financial Services Commission (FSC) confirming outflows accelerated sharply in the second half of 2025. Traders are fleeing to offshore derivatives platforms in jurisdictions offering leverage and hedging tools banned locally, forcing regulators to choose between tax revenue and market retention.
The Mechanics of the Exodus
The data paints a picture of a market structure failure. While the FSC noted a 14% increase in outflows to 90 trillion won ($60 billion) in the second half of the year, the drivers are structural, not sentimental.
Domestic giants like Upbit and Bithumb are legally restricted to spot trading. In a volatile market, this restriction renders them obsolete for sophisticated traders looking to hedge downside risk or speculate with leverage.

This is not a sell-off. It is an arbitrage migration. A joint report by CoinGecko and Tiger Research estimates thatof the total outflows flowed directly to Binance.
South Korean traders now account for approximately 13% of Binance’s futures volume. The net result is a massive transfer of fees abroad; foreign exchanges earned an estimated 2.7 times more revenue from Korean users than domestic platforms did in 2025.
The disparity has crushed local profitability. Despite a 31% rise in deposits to 8.1 trillion won ($5.4 billion), operating profits for South Korea’s 18 exchanges collapsed by 38% to 380.7 billion won ($253.4 million). The volume is there, but the high-value transactional velocity has moved elsewhere. We are seeing similar liquidity demands globally; EDX Markets launching KRW perpetual futures suggests institutional players are already positioning to capture this volume offshore if domestic regulations don’t adapt.
The FSC report explicitly linked the outflows to “arbitrage and other similar activities,” a tacit admission that the current regulatory framework is bleeding value.
Regulatory News: The Policy Gap
The decision to delay the tax is an emergency brake, not a solution. The opposition Democratic Party, previously adamant about implementing the tax in 2025, capitulated after realizing the Capital Flight could permanently cripple the domestic fintech sector.
With 11.1 million crypto accounts in the country, representing over 20% of the population, the political cost of taxing a shrinking market became untenable.
