The Return of South Korea's Kimchi Premium

The "Kimchi premium," a term for South Korea's higher Bitcoin prices compared to the international market, recently hit a two-year peak. This premium allows for an arbitrage opportunity, where Bitcoin is bought globally and sold in South Korea for profit, a strategy once used by Sam Bankman-Fried to earn millions. However, due to South Korea's strict financial regulations, converting these profits to cash is challenging. This situation limits the strategy's accessibility to smaller traders and prevents large funds from benefiting.

The "Kimchi premium" showcases the price gap between Bitcoin on Korean and global exchanges. Despite its theoretical simplicity, capital controls in South Korea make it hard for investors to repatriate large sums, narrowing the window for exploiting this price difference. Sam Bankman-Fried, known for his now-defunct firms Alameda Research and FTX, famously capitalized on this premium, claiming to make up to a million dollars daily when the premium was around 50%.

Observers note that the premium's return signals increased interest from Korean retail investors. According to Ki Young Ju of CryptoQuant, this scenario indicates growing FOMO (fear of missing out) among local investors. As the premium rises, more traders are likely to move their Bitcoin to Korean exchanges like Upbit, as seen by a significant reserve increase in February. Currently, Bitcoin's price remains stable, with the broader cryptocurrency market index, the CoinDesk 20, experiencing a 5.32% increase. This resurgence of the Kimchi premium underscores the localized dynamics of the cryptocurrency market and the challenges and opportunities within.
