South Korea's Crypto Volume Craters 89% as KOSPI Hits 8,800

South Korea’s crypto exchanges are in a deep slump. Daily trading volumes across the country’s top platforms have dropped 89% year-over-year, falling from an average of roughly 17 trillion won per day in mid-2025 to about 2.7 trillion won, or around $2 billion, by late May and early June 2026, exchange data show.

The money didn’t vanish. It rotated into equities. The KOSPI index surged past 8,800 in mid-2026, driven almost entirely by retail demand for semiconductor and AI-related stocks like Samsung Electronics and SK Hynix. A year earlier, crypto exchanges routinely outpaced Korea’s stock market in daily turnover. In July 2025, crypto volumes averaged 17 trillion won a day, comfortably above the KOSPI’s 10 to 15 trillion won. Now crypto accounts for roughly 2% of the KOSPI’s daily turnover.

The revenue hit is severe. First-quarter 2026 financials for major platforms showed declines of more than 50% year-over-year, according to company filings. The so-called “kimchi premium” – the price gap that historically made Korean crypto markets 5% to 10% more expensive than global exchanges like Coinbase or Binance – has flipped negative. That is a signal that local demand has genuinely evaporated rather than simply cooled, traders said.

South Korea implemented the Virtual Asset User Protection Act in July 2024, introducing stricter rules for exchanges and new safeguards for retail investors. The combination of tighter regulation and a roaring stock market created a powerful pull away from crypto.

Yet the retreat may not be permanent. In mid-July 2026, when the KOSPI experienced a roughly 4% intraday correction, trading volumes on Upbit, Korea’s dominant exchange, spiked more than 1,400% in a single day. That suggests Korean retail capital has not left the crypto ecosystem entirely but is currently concentrated in equity positions, ready to rotate back when conditions shift.
