Key interest rate
Key interest rate (policy rate)The interest rate that has the strongest effect on short-term market rates and is therefore considered the Central Bank’s key rate may change from time to time. Before the financial crisis in autumn 2008, the Bank’s key rate was generally considered to be the rate on its collateralised loans to credit institutions. Since the crisis, however, demand for Central Bank loans has been limited, and credit institutions have increased their deposits with the Bank. As a result, interest rates on deposits with the Bank have had greater impact on money market interest rates since 2009.
Below are data on Central Bank interest rates. Information on additional interest rate series can be accessed by clicking on “View data.”

Interest rates in the interbank market in ISK (%)
Central Bank to discontinue 9- and 12-month REIBOR listings
The Central Bank discontinued its listings of 9- and 12-month interest rates in the interbank market for krónur (REIBOR) on 1 July 2020. See the Bank’s news release dated December 18, 2019.
Interest rate reference in Icelandic krónur (IKON)
The Central Bank calculates and, since 1 April 2022, has published the IKON (Icelandic króna overnight) reference interest rate, which is the interest rate on unsecured overnight deposits denominated in Icelandic krónur and held by obliged entities. The interest rate is calculated from the agreements financial institutions make with their customers when they accept deposits at fixed rates for fixed commitment periods. The IKON rate is unlike the REIBOR rate in that IKON is based on actual trades, whereas REIBOR was based on bids.
Further information can be found at the Markets Department website.
Correction: 17th November 2023
In November, the Bank published corrected information on IKON interest rates and turnover for 15 dates starting from the beginning of 2022. The correction was necessary due to a software error that resulted in incorrect calculations of the weight of individual trades in 15 instances. Information on interest rates and turnover has been corrected, but because of the software error in question, interest rate values were marginally lower (by 0.002-0.037 percentage points) than they should have been in those 15 instances. The dates affected are all specially labelled in the data.
