Kimchi premium (regional premium)

The name comes from South Korea, where bitcoin has at times traded at a large premium over prices in the US or on offshore exchanges. Strong local demand meets a market that foreign traders cannot easily reach, because Korean exchanges require local bank accounts and real-name verification and the country restricts cross-border capital flows. Arbitrageurs who could buy abroad and sell in Korea would close the gap, but the rules make that slow and limited.

Traders read a high kimchi premium as a sign of retail euphoria in Korea, and a negative one, a discount, as local selling pressure. Comparable premiums appear in other countries with capital controls or unstable currencies, such as Argentina or Nigeria, where crypto and stablecoins become a way to access dollars.

Regional premiums are not free money. Moving funds across borders to exploit them can breach foreign exchange laws, banks may freeze transfers and the gap can close before the trade is done.
