Many posts here focus on current US petroleum inventories. Both big and small specs have been completely ignoring current supply and inventories for well over a year now. No one cares about present conditions anymore because Saudi Arabia over the last year has hit their production limit.
Up till about two years ago, Saudi had about three million barrells of spare capacity. Saudi played the role of swing producer: when inventories seemed to Saudi to be growing, Saudi cut production, and when inventories seemed too low--particularly going into the peak demand fourth quarter--Saudi raised production. Specs traded on these Saudi inventory assessments: Saudi crude is long haul and takes 6-8 weeks to reach the US gulf: if Saudi raised or cut too much, inventory levels would increase or decrease for about two months. Two months' inventory builds or draw downs could cause fears of gluts or shortages.
Over the last year, world crude demand has greatly increased with no increase in world crude capacity. As a result, Saudi has been pumping at full capacity. Notice crude specs no longer hang on every word from the Saudi oil minister: the Saudis are going to pump at full capacity under any current conditions, so Saudis really make no decisions on their crude supply.
This winter will be the first in the history of crude oil where world demand will exceed not just wolrd supply but also world capacity. Crude big spec knows this and they are going long not just the active front months but also even CLZ10. That this year's crude conditions are the first ever necessarily means crude prices will move in ways never seen before.
