Remember when Russia said the dollar sale of oil was coming to a close and the Middle East said oil would be priced in Euros?
Iran, no lover of the Great Satan of the West, has announced its central bank is selling Euros in favor of dollars and gold.
While the dollar has a lot of inflationary concerns weighing on it (at least in my mind), the Euro is apparently much worse. One wonders how this might impact China's potential unlinking of its currency to the dollar.
The fact that enemies of the United States are left investing in its currency does have a certain irony.
