PA,
Countries such as China and Japan hold huge quantities of dollars because of their huge export trade with the US. If oil were PRICED in euros, they would simply work out what todays exchange rate Euros/Dollars, and go into the currency market and sell dollars and buy euros. Here is the counterbalance. The Saudi's would then be holding Euros, and to buy computers, aircraft, food, etc, they would have to sell Euros and buy dollars. As the Saudis are huge investors in US treasury instruments, they would then have to convert euros to dollars to buy the core of thier national savings.
This is one huge headache for the Saudi's, and on every currency transaction there is "slippage", ie, some middleman makes a profit.
The net result of all this is very neutral. There is no real damage to the US, it just sounds good on paper. Iran has been doing this for years and there is no real impact. Remember, even including all that oil, the GNP of all Arab countries COMBINED is less than that of Portugal.
Saudi has a huge population of unemployed young people, who essentially behave like they are trust fund babies, refuse to get jobs, and the jobs that are availble, they are too good to take. Unemployment is over 40% in these categories. Saudi needs to pump all the oil they can to provide the benefits to people that they have grown accustomed to. They have to pump every drop they can.....
With oil prices high, the past few weeks have shown a lot more drilling and exploration activity. This is one way to become less dependent on Middle Eastern oil. A lot more projects become feasble all around the world, and the fear that cheap Iraqi oil will flood the market is now gone, allowing a lot more world wide projects to get funded and go forward.
Russia and their neighbors a pumping like crazy, and they love the high prices. China's GNP grew 9.9% annualized last quarter, and they will be looking for secure and reliable sources of oil. India is creating a strategic oil reserve, and it's economy is perking up too. Meanwhile the European economies are barely showing any sustained growth.
The Saudi's want to play in this economic growth, not alienate their customers. They want to sell as little oil for the highest price possible, to keep their people appeased. And as much as I really do not like the behavior of the Saudi's, at the end of the day the royal family has been close with the US for a long time, and this will not change....
