Oil price mocks fuel realities
By F William Engdahl
As business and consumers consider the implications for them of crude oil selling at US$130-plus per barrel, they should bear in mind that, at a conservative calculation, at least 60% of that price comes from unregulated futures speculation by hedge funds, banks and financial groups using the London ICE Futures and New York Nymex futures exchanges and uncontrolled inter-bank or over-the-counter trading to avoid scrutiny (see Speculators knock OPEC off oil-price perch, Asia Times Online, May 6, 2008).
US margin rules of the government's Commodity Futures Trading Commission allow speculators to buy a crude oil futures contract on the Nymex by paying only 6% of the value of the contract. At the present price of around $130 per barrel, that means a futures trader only has to put up about $8 for every barrel. He borrows the other $120.
This extreme "leverage" of 16 to one helps drive prices to wildly unrealistic levels and offset bank losses in subprime and other disasters at the expense of the overall population.
