  • The KORIBOR (Korea Inter-Bank Offered Rate) for the Korean won is the average of lending interest rates in the interbank market.
  • The KORIBOR is published for 6 maturities (1 weeks, and 1, 2, 3, 6, and 12 months) through the information providers at 11:00 a.m. each business day. After 3:30 p.m., you can also see the updated KORIBOR on the website of the KFB (Korea Federation of Banks). It has been published by the KFB since July 26, 2004.
  • Out of the 11 different rates quoted by the reference banks, the three highest and three lowest rates are disregarded, and the average (rounded off to two decimal places) of the remaining rates becomes the official rate for each maturity.
Calculation & Publication Rules
  • (1)The reference banks quote rates for each maturity to the service provider, Yonhap Infomax, between 10:40 and 10:55 a.m. each business day.
  • (2)The service provider calculates the average rate based on the provided rates, disregarding the three highest and three lowest rates (rounded off to two decimal places), and quotes all provided rates of each bank and the KORIOR to the Bank of Korea between 10:55 a.m. and 11:00 a.m. The BOK reviews the results and authorizes the service provider to announce them as the KORIBOR at 11:00 a.m.
  • (3)Upon receiving authorization, the service provider transmits the official KORIBOR to the information providers, and the information providers then immediately publish them.
  • (4)When a reference bank fails to quote rates, the service provider can still calculate the KORIBOR based on the other banks' quoted rates. However, there must be quotes from a minimum of 10 reference banks.
