The other thing I find rather surprising is the lack of consensus as to what exactly is going on. I'm certainly not an economist, but I dug into this as much as possible and I really can't say that I've hit on anything that would answer why this is happening.
I suppose one of the questions I would ask is if it were a reaction to the Saudi attempt to drop shale production—you sort of answered, but I want a clearer answer—isn't it something that they could easily correct just by shutting the taps just a little? It seems like there isn't a whole lot of fluctuation that's causing the price drop. Isn't it something they could correct rather quickly?
