The question is the time period between the doublings

I disagree. The question is how wide the disparity between rich and poor can get before social conditions deteriorate. If one drives a car an average of 12,000 miles per year - at 20 mpg. Thats about 600 gallons of gas - at $4 that is about $2,500 - not going to impact the rich one bit. But people with car loans, house loans, vacations, etc. that might be good slug of their discretionary income - if it doubles again there will have to be new social rules. People won't just stay at home and they won't be able to commute to work at the margin. (new social rules =carpooling, curfews, odd even driving days, and the other IEA recommended measures at a minium, but may require rationing, consumption taxes, and further measures.

"..further measures", Nate? Like civil disorder and revolution, maybe......?

The difference between $60 oil and $120 oil is that forced energy conservation is simply moving up the food chain--from a poor third world consumer to lower income and middle income Americans.

Let's assume, for the sake of argument, an annual net export decline rate that looks this: -2%, -4%, -6%, -8%, -10%. . .

We get a price response, followed by a demand response, and then we get a sharper decline rate, requiring an additional price/demand response--aggravated by the fact that forced energy conservation is moving up the food chain. Wherever we are headed and whatever the consequences, IMO, this is what is driving the price. A steady exponential decline rate would show up on the following chart as a flat line. What we see is an accelerating net export decline rate:

Increased oil prices reduce almost everyone’s disposal income (it acts as a tax).

For the US a doubling in the oil price will heavily impact their already high trade deficit? How long will other nations be able or willing to finance an accelerating American trade deficit?

Some of this lenders like China will also be impacted by the increase in oil prices, and should thus (under equal circumstances) be left with less US dollars to finance an accelerating US trade deficit.

Obviously something will have to give when the oil price reach critical levels (I don’t know what that price is as of now and when in time this will happen) even adjusted for a US dollar in almost free fall.

The increase in oil prices will affect food prices, interest rates, travelling etc. thus forcing the average household to increasingly prioritize their available means.

Increased oil prices reduce almost everyone’s disposal income (it acts as a tax).

It does not act as a tax. A tax moves money from the citizen to the government which the government then (ostensibly) uses within the domestic economy. A high oil price (for an importer) moves money from within the domestic economy to an external economy. Since our economy is measured by how much money is moving around within it, moving money outside of the economy is bad for the economy.

Jim,

Thx for the more precise formulation. (slight populistic use of a picture from my side)

For an oil importer I agree, increasing oil prices will move and increased amount of money out of the economy.

My prime intention was however to draw attention to that there must (as of now) be a limit to how high oil prices will go before it starts to affect demand.

Looking at EIA data for total petroleum products consumption it looks as this zone is being entered now, looking and the increasing number of airlines reporting cutbacks and reduction in flights, the present run up in oil prices have already stated to take some effect on demand (consumption). And there is probably more in the pipeline.

I would expect there to be a timelag from the run up in prices until it turns up in reduced demand.
