You do realize that you chose a chart for OECD demand only to show that "demand is cratering?" It is not. Here's the world demand chart:
http://omrpublic.iea.org/world/wb_wodem.pdfThe chart you selected shows what I said above: Developing countries, particularly in Asia, are outbidding the West. Global demand has been consistently running just ahead of supply. That's why prices are remaining high. But again, you can just look at the spare capacity data to tell you the same thing.
I think we're done here. You have not shown any data to prove the influence of speculators, which would be found in the exchanges, not aggregate supply/demand data. We have drifted off-topic here. The IEA's projection for 2012 is an entirely different subject.
