An interesting phenomenon has happened in the last couple of days. The oil futures market has gone into a state known as "contango". I'm not going to go into any detail on the specifics -- if you're curious just do some googling. As a layman, all you really need to know is that, thanks to some complicated financial mumbo-jumbo, banks will now begin to hoard oil in storage tanks, driving up the price. And then they will sell that oil back to the public for obscene windfall profits.

Morgan Stanley, Goldman Sachs and Deutsche Bank got into hoarding early in 2004:

A LARGE warehouse in Amsterdam may seem an unusual place to attract the City’s top traders and hedge funds. But, in the past few months, Morgan Stanley has been accumulating warehouse space in the Netherlands to store its hottest new property — oil.

Meanwhile, banks such as Morgan Stanley are also beginning to move into the physical market to buy oil — or even entire oilfields.
Goldman Sachs recently bought 10m barrels of oil.
