Yep and as oil prices drop the sources that need $100 a barrel oil to be profitable will start producing less and less. US Shale oil comes to mind. The Saudis, Russians, Iraq, Iran. Nigeria, Venezuela and Libya need oil prices over $100 a barrel to break even, ok the Suadis only need $93 a barrel, but how long do you think they will go before they cut production?
I'll wait and see.
