A fun read on such things but lacking the ultimate power of 'liquidation only' is:....Should prices see $8.50 the opportunities on the short side would almost be a lock.I say almost because the serious money in commodities can pretty much get prices to where they want them, at least for short periods.When the Billionaire Hunt brothers were attempting to corner the silver market in January 1980 the head of one of the world's largest grain traders said "Those boys don't know what deep pockets are".The "commercials" had been shorting into the Hunt bros. buying and the grain trader was at the top of the "commercial" heap.On January 21 the COMEX went "liquidation only".On January 22 the CBOT went "liquidation only".On Tuesday the 22nd silver closed at $34, down 27% from its close the previous Friday.The Hunt's still had enormous paper profits but any attempt to book them would smash the markets even further.Prices declined to $17 by March, down 66% from the January high and the Hunt's were receiving calls of $60 Million per day in variation margin. On March 27 the price dropped from $21.62 to $10.80 and one of their brokers, Bache was in violation of net capital requirements and another, Merrill Lynch was on the brink.As the attorneys got involved over the next few years, oil prices headed south, destroying the value of Daddy's creation (and the brother's piggybank) Placid Oil.Bunker Hunt filed for bankruptcy in September 1988 as did his brother and Placid.At the time the grain trader said "Those boys don't know what deep pockets are" it is probable that the various branches of the Hunt families comprised the wealthiest "family" in America.That's why I say "almost" a lock.

Again, apropos of nothing in particular 2012's "How to Manipulate Non-storable Commodities Markets" links to "a snappy little 32 page paper by Craig Pirrong who you may know by his nom de blog The Streetwise Professor. His is one of the few blogs that posts on Gazprom more than we do though we probably have more on Enron."
Amazingly Prof. Pirrong wrote this paper a couple months before the California Electricity Crisis of 2000-2001 began!
