How do you explain the rising prices in the rest of the world except Saudi Arabia $0.09, Kuwait $0.08, Venezuela $0.12 and a few others where the prices have not changed in a while?
The price of oil and gas are not linier. It's oil that is being driven up by a combination of falling dollar and spectulation, due to the instability of the middle east. The spectulation is further fueled by the falling dollar, with speculators believing that as the U.S. dollar collaspes, oil will have to continue to rise in price with dollar inflation. Whereas the future of the dollar was questionable in the past. With trillions recently being printed and our government having to borrow or print several trillion per year just to function, it's now become a pretty safe bet that the dollar will fall dramaticly and oil spectulators want to get in low before oil inflates to meet the rising number of dollars in the world.
The price of gas is affected by the price of oil, but how it moves is different in each market. Furthermore, each market has a different set of costs and taxes.
For example, gas prices are extremely high in Europe and Canada due to the taxes imposed on it. Gas prices in certain parts of the U.S. is more expensive depending on the cost to ship it and then there's factors such as demand and availability of gas from the various refineries.
Oil might be dirt cheap, but if the refinery can't produce it, gas will still rise.
The reason I mention the dollar is because its one of the most significant factors affecting the price of oil and oil is one of the most significant factors affecting the price of gas.
Where gas is extremely cheap, the foreign government is subsiziding it through little or no taxes and importing expensive gas, but selling it to the public at a loss.
There's a sustained effort to keep oil prices high, because middle east countries that the U.S. and the west are friendly too, desperately need higher oil prices to function. Especially with a falling dollar. I'm sure there are numerous efforts abound to keep the price of oil high, despite falling demand and less demand than when our economy was doing well.
One of those efforts is likely the reason we are in Libya ensuring yet more instability in the middle east.
But that's just my opinion.
