Saudi Arabia’s King Abdullah likes $75 a barrel oil. But Ali Naimi, his oil minister, appeared to tweak the kingdom’s oil price ideal to $60-75. “Forty dollars is not enough, you need between $60 and $75 dollars to allow marginal producers to continue producing ethanol, heavy oil,” Mr Naimi said this morning at a conference in Geneva, according to AFP. He said today’s low oil price of $44 a barrel was just as unsustainable as the soaring price of last summer, when futures rallied to a record $147. But Mr Naimi may not be going soft. With the dollar’s recent rise, maybe $67.5 is the new $75 for Opec members, all of whom sell their oil in dollars. Yesterday, the group proved it could live with lower prices for a little longer, by deciding not to embark on a new round of production cuts, despite the risk that this could push down oil prices as seasonal demand fell because of the end of the winter heating oil season in the western hemisphere. So far the market has shrugged its shoulders.
