Saudi Arabia did it. After stonewalling for weeks, all attention is on the House of Saud and its refusal to let OPEC cut production, even by a modest 2 million barrels a day. The immediate impact of this decision was felt with WTI falling to $65.99, its lowest point in over four years, while Brent settled at $70.07 after a near $7.67 drop. That Saudi Arabia thought this to be “a great decision” shows the defiance of the former top global oil producer when confronted with a new energy world order. The news also handed out a battering to oil stocks, with Premier Oil falling by 7%, with Statoil, Total and Shell all down around 4%.

Despite this immediate impact, Western powers quickly moved to dispel concern about the impact of this decision on their economies. Canadian Finance Minister Joe Oliver  stated that Canada had not counted on an OPEC deal, saying that “when we took into account the oil price decline…we made the assumption that the prices would stay at the low level for the entire period.”

Will OPEC break up?. That is the question.  Russia needs high oil prices to stay financially stable, especially with economic troubles and political sanctions costing well over $100 billion a year. The shift in production power to the U.S., allied with the likes of Canada, Mexico and Brazil, has exposed the deep divisions between OPEC members that were once papered over in the name of joint economic prosperity. If the shale boom truly makes the U.S. energy independent and the oil export ban is lifted, certain OPEC members may shift their allegiance.

Much has also been made of the fact that low oil prices will also help the gas-guzzling U.S. economy at the pump, while also trickling down to help consumers in Europe and Asia.

MarketWatch is clearly loving this situation, crowing that those who will suffer are hardly U.S. allies. It estimates that with production ever fluctuating, Libya needs prices at $185 a barrel to balance its budget, while Iran needs $133, and Russia needs $100. “The rogue states’ cash flow can’t handle it. OPEC’s low-cost producers are Western-friendly powers like Kuwait.” Its economic analysis continues with the fact that U.S. shale-oil production is expanding by the capacity of Libya every year, and that American production would still be boosted at $60 a barrel, albeit in a limited fashion. Its final rhetorical flourish is perhaps a tad over-played but is emblematic of markets that are not as worried about OPEC’s decision: “If shale’s job is depriving rogue regimes of oil leverage, it’s done.”
