What would a "gold for oil" system mean for the petrodollar and the U.S. economy? Are Russia and China hoarding massive amounts of gold because they plan to kill the petrodollar? Since the 1970s, the U.S. dollar has been the currency that the international community has used to trade oil around the globe. This has created an overwhelming demand for U.S. dollars and U.S. debt. But what happens when the rest of the globe starts rejecting the increasingly unstable U.S. dollar and figures out that gold can be used as a currency in international trade? The truth is that it doesn't take a lot of imagination to figure that out. Demand for the U.S. dollar and U.S. debt would fall off the map and there would be a rush into gold unlike anything we have ever seen before.
