  • What is the exchange rate index?

    The exchange rate index is the geometric mean of the exchange rates of major currencies against the Icelandic króna. A rise in the index indicates a decline in the exchange rate of the króna. The exchange rates of the foreign currencies are weighted together according to the composition of Iceland’s external trade. The selection of currencies and the weights used in the exchange rate index are discussed in greater detail under the link Revised currency baskets.
  • Where can data on exchange rates be found?

    Exchange rate listings can be found under the link Official exchange rate. Exchange rates of other currencies can be found on a number of websites, including oanda.com. The Central Bank of Iceland cannot be held liable for information found on such websites or for use of such information; furthermore, the Bank wishes to remind the reader of the general disclaimer concerning the reliability of data on the internet, which can be found on the Copyright and disclaimer page on this website.
  • When are exchange rates listed?

    The exchange rate of the Icelandic króna is determined in the foreign exchange market, which is open between 9:15 hrs. and 16:00 hrs. on weekdays. Once a day, the Central Bank of Iceland fixes the official exchange rate of the króna against foreign currencies, for use as a reference in official agreements, court cases, and other contracts between parties that do not specify another reference exchange rate; cf. Article 29 of the Act on the Central Bank of Iceland, and lists the official exchange rate index at the same time. This is done around 16:00 hrs. each day that regulated foreign exchange markets are in operation. Under extraordinary circumstances, the Central Bank may temporarily suspend its quotation of the exchange rate of the króna.
