The dual rate theory does not make sense in a market based economy. The U.S. government is not buying enough oil for this to make sense. The vast majority of oil bought around the world is purchased by nongovernmental companies (China excluded). The government does not buy oil for Exxon or Shell. This would benefit China, because they are a socialist society, but it would not benefit limited governments in democracies. Our government does not use that much oil for governmental purposes. The private sector drives our economy. A single rate makes much more sense. Also, how can there be a limited time to exchange a currency? I can exchange any currency at any time as long as the currency has value. If the IQD rv's then it will be a stable currency and will fluctuate in value just as other major currencies. The 45 day thing makes no sense if you have even a little knowledge of how international finance and economics work. Is someone going to tell banks that Iraq's currency is only going to be good for 45 days. If so, then Iraq is screwed worse 45 days after rv, than they are now.
