ISK/DKK: what to know
The ISK/DKK rate shows how much DKK you get for 1 ISK. Right now, 1 ISK buys 0.0536 DKK at the mid-market rate. In the other direction, 1 DKK is worth 18.6700 ISK.
In the short term ISK is driven mainly by tourism, fishing and commodity prices, while DKK responds to its fixed peg to the euro.
The Icelandic Krona (ISK) is issued by Central Bank of Iceland. After the 2008 crisis Iceland withdrew its cents (aurar) — only whole krónur circulate. The Danish Krone (DKK) is issued by Danmarks Nationalbank. The Danish krone is tightly pegged to the euro within a narrow band.
Use this mid-market figure as your benchmark: compare it with the rate your bank or broker quotes, and the difference is the margin you would pay.
