Worse than an Iranian nuclear attack?
Weaned off the almighty commodity, the US dollar can have a deeper impact on the US economy than a direct nuclear attack by Iran. The permanent demand for dollar-denominated paper stems substantially from the fact that until now almost all resources of the world are quoted in it.
While this led to the eurodollar (US dollar-denominated deposits at foreign banks or foreign branches of American banks) market in the 1970s, the new terms of trade could ring in the demise of the dollar as the premier reserve currency... Iran holds a strong hand as the No 2 producer of crude behind Saudi Arabia, pumping 5% of the world's oil demand. Politicians there will also keep in mind that dollar deposits might become a burden in the future, if the US steps up its current war of words to the level of economic sanctions in the attempt to halt construction of Iran's nuclear power plants. Money in the bank does not help when you have no access to it. Substituting Iran's domestic oil demand partly with nuclear power will place the country in a win-win situation. Cheaper nuclear energy and increases in oil exports from the current level of roughly 2.5 million barrels a day will result in a profitable equation for Iran.
Only one major actor stands to lose from a change in the current status quo: the US, which with less than 5% of the global population, consumes roughly one third of global oil production. Oil in euros would benefit millions more in the EU and its trading partners, though. And it would loosen the grip the US has on OPEC members. Thinking of the rapid growth of hostilities between the US and Arab nations in recent years, a renunciation of the dollar appears to be more than just an Arab daydream.
As this development poses a very real danger to the superior status of the greenback and the interests of the US, the "president of war" can be expected to take a strong line against the winds blowing from the Middle East. One may be reminded that Saddam Hussein had entered into discreet talks with the EU, proposing to sell his oil for euros. That was in the year before the first oil war of this century. Source:
