The US Dollar / Krone is the most popular pair to trade the Norwegian currency. The price of the Krone is influenced by changes in interest rates and oil prices. The pair saw a lot of volatility between 2002 and 2008 because of the changes in oil prices and the global financial crisis. Norway's economy largely benefits from trade, and a lot of that trade is done with the UK and the Euro-zone. Therefore, the Krone is significantly affected by changes in those economies.
USDNOK is looking to re-enter 15-month rising support after a significant plunge in June, with USDSEK following a similar pattern of resuming the broad uptrend.
