In truth, the spare capacity that the world cares about — that the oil futures market cares about — is not the inventory level. But rather, actual production capacity that can be brought on immediately. You can see the problem, from a price standpoint. If the world loses Libya’s 1.5 mbpd production for 90-120 days, and starts drawing down above-ground inventories, this only makes the inventory cushion that much thinner for any new supply disruptions. The question on the mind of the oil market therefore is not Mr. Fyfe’s 1.6 billion barrels of crude, but whether countries like Kuwait, the U.A.E. and especially Saudi Arabia or even Russia can lift supply. Immediately.
