In the short term the market can be manipulated, such as by speculation...
Google "high oil prices speculation" and you'll find many financial news sites and various experts think that the current high prices are caused by speculation. Artificial price hikes are never sustainable so eventually they will come down.
Damn, Gollumx has turned economist on us!
I agree, speculation is the magic word. The financial sector never seems to be content with traditional investments and always gets sucked into using leverage (mortgage crises/credit swaps) and we are seeing it again with commodities. Leverage is utilized everyday in the stock markets as people trade options and use margin. In the later example, 50% of the purchase price of a -security has to be in ca-sh and up to 50% can be margin(loan). With commodities the number is more like 30 to 1. That means for $1 you can control $30 of a certain commodity. Used to be that commodities was territory of big firms and traders, not any more. With the advent of exchange traded funds and other investment instruments, just about anyone can pour money into commodities and just about every one is. I had an 80 year old client ask why we had her in safe secure investments and were not pursing gold
Although the demand for oil from China and other countries has gone up, it is no where near the level that would cause oil prices to climb as high as they are. The answer is LEVERAGE.
As to the original question, I pay 79c for gas and $4.19 for the stuff that makes my car go.
