The Norwegian Krone (NOK) is the official currency of Norway. It is subdivided into 100 øre. The currency symbol for the krone is "kr," and it is issued by the Norges Bank, which is Norway's central bank. The krone has been in use since 1875 and is known for its stability, reflecting Norway's strong economy. The value of the krone can fluctuate based on various factors, including oil prices, as Norway is a significant oil producer. The exchange rate of the krone against other currencies, such as the Euro or the US Dollar, is closely monitored by traders and investors.
