Ready for $262 a barrel oil prices ?

"I'm very worried about the supply-demand balance, which is very tight," billionaire investor George Soros says.

"U.S. power and influence has declined precipitously because of Iraq and the war on terror and that creates an incentive for anyone who wants to make trouble to go ahead and make it."

"Iran is on a collision course and I have a difficulty seeing how such a collision can be avoided,"

To come up with some likely scenarios in the event of an international crisis, his team performed what's known as a regression analysis, extrapolating the numbers from past oil shocks and then using them to calculate what might happen when the supply from an oil-producing country was cut off in six different situations. The fall of the House of Saud seems the most far-fetched of the six possibilities, and it's the one that generates that $262 a barrel.

More realistic -- and therefore more chilling -- would be the scenario where Iran declares an oil embargo a la OPEC in 1973, which Browder thinks could cause oil to double to $131 a barrel. Other outcomes include an embargo by Venezuelan strongman Hugo Chavez ($111 a barrel), civil war in Nigeria ($98 a barrel), unrest and violence in Algeria ($79 a barrel) and major attacks on infrastructure by the insurgency in Iraq ($88 a barrel).

Regressions analysis may be mathematical but it's an art, not a science. And some of these scenarios are quite dubious, like Venezuela shutting the spigot. (For more on Chavez and Venezuela, click here.)

Energy chiefs at the World Economic Forum in Davos downplayed the likelihood of a serious oil shortage. In a statement Friday, Shell's CEO Jeroen Van der Veer declared, "There is no reason for pessimism." OPEC Acting Secretary General Mohammed Barkindo said "OPEC will step in at any time there is a shortage in the market." But then no one in the industry, including Van der Veer, foresaw an extended run of $65 oil -- or even $55 oil -- like we've been having.

It's clear that there is very, very little wiggle room, and that most consumers, including those in the United States, have acceded so far to the new reality of $60 or even $70 oil. And as Soros points out, the White House has its hands full in Iraq and elsewhere.

Although there are long-term answers like ethanol, what's needed is a crash conservation effort in the United States. This doesn't have to be command-and-control style. Moral suasion counts for a lot, and if the president suggested staying home with family every other Sunday or otherwise cutting back on unnecessary drives, he could please the family values crowd while also changing the psychology of the oil market by showing that the U.S. government is serious about easing any potential bottlenecks.

Similarly, he could finally get the government to tighten fuel-efficiency standards and encourage both Detroit and drivers to end decades of steadily increasing gas consumption. These kinds of steps would create a little headroom until new supplies do become available or threats like Iran's current leadership or the Iraqi insurgency fade.
