ISK/VND: what to know
The ISK/VND rate shows how much VND you get for 1 ISK. Right now, 1 ISK buys 213.2628 VND at the mid-market rate. In the other direction, 1 VND is worth 0.00468905 ISK.
In the short term ISK is driven mainly by tourism, fishing and commodity prices, while VND responds to exports and central-bank policy.
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 Vietnamese Dong (VND) is issued by State Bank of Vietnam. The đồng has very high denominations — notes go up to 500,000.
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.
