CTR kimchi premium FAQ
What is the CTR kimchi premium today?
CTR trades at a 0.46% discount on Korean exchanges against Binance right now (Bithumb -0.46%). The figure refreshes about once a minute from the Upbit and Bithumb public tickers.
How is the CTR kimchi premium calculated?
The CTR KRW price on Upbit or Bithumb is divided by the Korean USDT price in won (₩1,334 on Upbit now) and compared with the CTR price on Binance ($0.01768, USDT perpetual): premium = KRW price ÷ USDT/KRW ÷ Binance price − 1. A venue counts only when it traded at least ₩500.0M of CTR in the last 24 hours.
Can you arbitrage the CTR 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 CTR deposits or withdrawals, and the premium can close before a transfer lands. Nothing here is financial advice.
