SOMI kimchi premium FAQ
What is the SOMI kimchi premium today?
SOMI trades at a 0.56% discount on Korean exchanges against Binance right now (Upbit -0.06%, Bithumb -1.06%). The figure refreshes about once a minute from the Upbit and Bithumb public tickers.
How is the SOMI kimchi premium calculated?
The SOMI KRW price on Upbit or Bithumb is divided by the Korean USDT price in won (₩1,362 on Upbit now) and compared with the SOMI price on Binance ($0.2204, spot): premium = KRW price ÷ USDT/KRW ÷ Binance price − 1. A venue counts only when it traded at least ₩500.0M of SOMI in the last 24 hours.
Can you arbitrage the SOMI kimchi premium?
Not easily. Korean exchanges take won only from verified local bank accounts and South Korea limits moving won abroad, which is why the gap can last. Transfers take time, an exchange can suspend SOMI deposits or withdrawals, and the premium can close before a transfer lands. Nothing here is financial advice.
