For more than a year now, commodity prices have been under pressure from the strong U.S. dollar and slowing global demand. This has made a huge dent in the balance sheet of many net exporters of resources, in turn weakening their currencies.

This should come as a shock to no one, but what most people don’t realize is just how closely some currencies track certain commodities. When I presented at the International Mining and Resources Conference in Melbourne, Australia, earlier this month, I shared several charts that show this correlation. Many attendees were astounded—and we’re talking professional economists, money managers and CEOs here.

With that said, I think it’s important that you see this correlation as well. Below are five world currencies that have been impacted by lower commodity prices.
