That means the balance of growth has to come from OPEC, which has been unable and/or unwilling to increase capacity fast enough in recent years to keep up with increases in demand. In fact, OPEC's spare capacity—the extra crude it could produce if necessary—has dwindled back below 2 million barrels per day for the first time since the third quarter of 2006, the IEA says.
That will likely make the hair-trigger markets even more sensitive to potential outages that could be caused by hurricanes on the U.S. or Mexican Gulf Coast, or political tensions from Iran to Nigeria. "Higher prices are needed to choke off demand to balance the market," the IEA said. On cue, U.S. crude, which had declined on June 9 following the June 6 record of $139.12, rose by 2.26%, to $137.00 per barrel, Reuters reported.
