Even Business Week is covering the Iranian oil bourse:

Analysts skeptical of Iran oil plan

Iran took a step on Friday toward establishing an oil market denominated in euros, a plan analysts described as highly unlikely to materialize but which in theory could have serious consequences for the U.S. economy.

If the market were to succeed -- or if Iran simply demanded payment for its oil in euros -- commodities experts said it could lead central bankers around the world to convert some dollar reserves into euros, possibly causing a decline in the dollar's value.

Oil is currently denominated in dollars around the globe, whether through direct sales between producers and consumers or in trades made on markets in New York and London.

But if one day the world's largest oil producers allowed, or worse demanded, euros for their barrels, "it would be the financial equivalent of a nuclear strike," said A.G. Edwards commodities analyst Bill O'Grady.

But he doesn't think it's likely:

O'Grady said there are practical reasons why the Iranian threat is an empty one.

For starters, Iran is not a very attractive site for a market, given the volatile nature of its politics, the U.S. sanctions against it and the lack of a fair legal system. Moreover, there is no indication that the European Union is interested in vying to become the world's central bank, which requires a willingness to run large currency deficits, he said. For the U.S., that has meant allowing cheap imports to undermine the strength of some major industries, including textiles, autos and electronics manufacturing.

Dubai however may be a very good place for a Euro based oil bourse however. The point is, the dollar is on its way out as a world currency.

The best write up on our fiat money system and on the petrodollar I've seen is on the www.urbansurvival.com site, called "Island Economics" there are two parts, I and II, and our money system is described in terms of the TV show Gilligan's Island, to make it understandable to Americans.

This is what I was getting at the Thursday Open Thread concerning the falling US Dollar.  

Some of the increase in the price of oil is due to the decrease in the value of the US dollar.  It is taking more dollars to buy the same unit of oil, but it's taking fewer euros to buy the same amount of oil.

I believe some of what is going on is the decreased holdings of US dollars at various national banks throughout the world.  What's replacing those reserves?  Gold, euros, and a basket of asian currencies?  You bet.  As I've heard it a millions of times...to understand the real driver of global activities....FOLLOW THE MONEY!!!!

The MSM (or the federal gov't.) do not want people to recognize this due to its ramifications.

And even though the IOB seems to have lost some steam, I keep feeling it's lurking under the noise.  Something is afoot here that is under the immediate radar.

Keep in mind that the us dollar has actually STRENGTHENED vs other currencies in the past 12 months, despite its recent slide. So viewed year over year, it take MORE euros to buy oil than dollars. Not disputing your general point but the slide of the dollar is still small and still very recent.
Menzie Chinn at Econbrowser has a nice pieceon central bank reserves and oil.  It includes this graph of global bank reserve increases lately:

Clearly, the oil exporters are becoming a growing part of the mix, with Asia becoming less important.  However, it's not at all clear that there's any relationship between the decision of what currency to use for trading oil and that of what currency to hold central bank reserves in (a point well made by Jim Hamilton back in January).

Since the Cdn dollar low in 2002, the US dollar is down 47.5%.
Pricing oil in euros makes economic sense to Europeans, because it eliminates the currency (dollar) risk. Norway is part of the European free trade zone, and has therefore most of its imports and exports other than oil priced in euros. http://www.energybulletin.net/13081.html
The same holds true for the bilateral trade between Germany and Russia http://www.themoscowtimes.com/stories/2003/10/09/047.html
La grande nation, the French also would prefer to buy oil in their own currency. http://www.finanznachrichten.de/nachrichten-2005-04/artikel-1892089.asp - 18k
So when Britain becomes net oil importer in the near future the switch from dollars to euros just might be a logical next step.
But the British Pound is traded separate from the Euro as well...
More MSM hogwash. Now the US current account deficit is mandatory or caused by the dollar's status as the reserve currency? Utter nonsense. The article makes me think that maybe the Iranian bourse will fly.
