I agree Chris -
I think we need to rethink "free market" theory and paradigms, given the lopsided leverage available to the largest Central Banks, particularly when multiple CB’s around the globe can, and do, act in concert.
The Precious Metals, due to their status as the "mortal enemies" of the carte-blanche Fiat-currency regimes, are particularly prone to Central Bank manipulation (oddly, the CB’s don’t appear ready to "let go" of the stuff, even given their definition of it as "relic" metals…)
Ted Butler, a well known Silver guru, had an article yesterday, in which he tracked for August 2008, the open positions and COT (commitment of traders) reports from the "regulators" of the futures markets - CFTC.
From that data, it is obvious that during August 2008, "…one or two U.S. banks sold short the equivalent of 140 million ounces of silver in one month. That’s more than 20% of world annual mine production. Less than three U.S, banks sold more than 10% of world annual mine production of gold simultaneously…"
That kind of concentrated short-selling (in the case of silver), is unheard of in corn, oil, or other commodities.
Of course, the paper-price of silver and gold had the hardest falls in several years during July/Aug, and this must certainly be by design ("we certainly don’t want the populus to flee to the safety of tangibles during a credit crisis…").
But you are correct, there is a large disconnect between the paper-price, and the physicals-price - i.e., the basis.
In fact, the huge degree of leverage between the number of open contracts in the futures market, and what can possibly be physically delivered, is similar to the "fractional-reserve" concept used in banking in general.
This leads to some possibility of a "run on the gold and silver supply" at some point, should a crisis-mentality continue to grow, particularly true with the huge volumes in the ETFs of SLV and GLD.
This possibility is one further reason that the CBs continue to strongly "participate" in the psychological trading of the gold and silver markets.
It is also a reason that we need to broaden our understanding beyond "free market" supply & demand mechanisms, and not kid ourselves on how the "rules" are written.
