$BTC has long traded at a premium in South Korea compared with other markets. This price gap is known as the kimchi premium. For years, it has been treated as a signal of sentiment among Korean retail investors—and as an easy opportunity to exploit.
A study published this June analyzed 16,228 cross-market arbitrage trades, 96 percent of which took place within five minutes. At that speed, manual traders have already been squeezed out.
A more fundamental obstacle lies in settlement. South Korea strictly controls the movement of funds overseas, making it difficult to remit arbitrage profits. The price gap may be there, but the gains may not be within reach. Regulators are studying won-denominated stablecoins; if introduced, they could ease settlement friction considerably.
Estimates from the same period put South Korea’s crypto economy at around $449 billion, with local demand remaining strong.
The kimchi premium is still there, but its readings increasingly reflect market efficiency and access.
