I am a currency used in a country famous for its fjords, Vikings, and the Northern Lights. I'm not part of the Eurozone, and my value can be affected by oil prices. My coins feature a monarch, and I am subdivided into 100 smaller units. What currency am I?

1. My country is not in the European Union.
2. My country is known for its stunning natural landscapes.
3. I am a Scandinavian currency.
4. My symbol is 'kr'.
