South Korean retail traders have pushed the Korean won to account for a staggering 30% of all global spot cryptocurrency volume in 2026, according to a new Kaiko research report. The data, which specifically tracks spot trading activity rather than derivatives or futures, highlights the outsized influence of won-denominated pairs on exchanges such as Upbit and Bithumb. With a population of roughly 52 million, South Korea’s share of global spot activity is far disproportionate, underlining an extraordinary concentration of retail participation and liquidity within its domestic platforms.
The composition of Korean trading reveals a striking divergence from Western markets: altcoins represent 85% of all domestic crypto activity, while Bitcoin and Ethereum account for just 9% and 6%, respectively. This means Korean flows can significantly sway altcoin prices worldwide. When Upbit lists a token or volume spikes on Bithumb, global markets often follow. The phenomenon is reinforced by the historical ‘Kimchi premium,’ where assets trade at higher prices on KRW pairs than on USD or USDT pairs elsewhere.
The Kaiko report also points to a deeper structural story. Despite handling roughly $26 billion in weekly turnover, Korean exchanges exhibit relatively thin order-book depth for Bitcoin. Upbit’s BTC KRW market depth sits at around $1–1.2 million, whereas Japan’s Bitflyer alone holds about $3.5 million in depth. This contrast indicates that while Korea dominates spot volume, Japan maintains a more stable liquidity structure for Bitcoin.
The surge in Korean crypto trading runs parallel to a rally in Korean tech equities, particularly Samsung Electronics and SK Hynix, which together drive the global supply of high-bandwidth memory chips essential for AI training. The iShares MSCI South Korea ETF returned over 37% year-to-date through March 2026, fueling retail risk appetite that spills directly into high-volatility altcoins. As one analyst put it, ‘This isn’t really a Korea bet; it’s a leveraged AI bet through a different door.’
However, the report flags a risk indicator: roughly 40% of altcoins held by Korean investors are currently trading at all-time lows—exceeding even the 37.8% recorded after the FTX collapse in 2022. The durability of Korea’s crypto dominance through 2026 may well hinge on Samsung and SK Hynix’s upcoming Q2 earnings, as the AI memory cycle continues to feed both equity and crypto markets.
