Greenspan and the Caspian

As part of the publicity for his memoir, just out today, Former Fed chairman Alan Greenspan has given a slew of interviews. In a chat with Bob Woodward of The Washington Post, he accents the knife's edge on which the world economy rests because of tight oil supplies, and inadvertently provides an argument for why the Caspian Sea is strategically important.

In the Post interview, according to Woodward, Greenspan said that the disruption of even 3 to 4 million barrels a day of oil could translate into crude prices as high as $120 a barrel; the loss of anything more would mean "chaos" to the global economy, Greenspan said. Read story

That is precisely the volume of oil exports expected from the Caspian -- from Kazakhstan and Azerbaijan combined -- after about a decade. The main fields involved will be Tengiz, Kashagan and Karachaganak in Kazakhstan, and offshore Baku in Azerbaijan.

As it appears now, much of this oil will pass through the East-West oil corridor championed by Washington, with its hub in Baku. It is why the U.S. has put so much diplomatic weight behind relationships with Georgia, Azerbaijan, Kazakhstan and Turkmenistan.

Oil prices are largely decided on the margin -- those last 3 to 5 million barrels of total daily world demand. In the next decade, the flow of Caspian oil will produce the equivalent of that margin.
