The commodity markets need some actual oversight. If you could see how little oversight they have now, you would be stunned. Hillary could still be making $100,000 on cattle futures under these same corrupt regulations and virtually nobody would know. Just like they are seeing it now with oil futures.
When trading commodities either up or down the more volatility the better.
As far as future oil supply difficulties, the Iranian nuclear weapons issue will sooner or later be addressed and addressed forcefully since that is the only lingo the mullahs comprehend. Iran is OPEC's second largest exporter, need I say more.
I do not disagree with the bulk of your comments concerning commodities & the energies. However much of the blatant crookedness which did exist at the trading firm/seasoned broker level has been substantially removed via fear from the Enron, WorldCom & other major investment scandals.
Instead of remaining on the sidelines you may want to investigate profiting from some of the selected market volatility, just proceed with caution in terms of which trading firm & the broker. Do the research.
