THE GREAT AMERICAN BUBBLE MACHINE

The basic scam in the Internet Age is pretty easy even for the financially illiterate to grasp. Companies that weren't much more than pot-fueled ideas scrawled on napkins by up-too-late bong-smokers were taken public via IPOs, hyped in the media and sold to the public for megamillions. It was as if banks like Goldman were wrapping ribbons around watermelons, tossing them out 50-story windows and opening the phones for bids. In this game you were a winner only if you took your money out before the melon hit the pavement.

It sounds obvious now, but what the average investor didn't know at the time was that the banks had changed the rules of the game, making the deals look better than they actually were. They did this by setting up what was, in reality, a two-tiered investment system — one for the insiders who knew the real numbers, and another for the lay investor who was invited to chase soaring prices the banks themselves knew were irrational. While Goldman's later pattern would be to capitalize on changes in the regulatory environment, its key innovation in the Internet years was to abandon its own industry's standards of quality control.

Goldman's role in the sweeping global disaster that was the housing bubble is not hard to trace. Here again, the basic trick was a decline in underwriting standards, although in this case the standards weren't in IPOs but in mortgages. By now almost everyone knows that for decades mortgage dealers insisted that home buyers be able to produce a down payment of 10 percent or more, show a steady income and good credit rating, and possess a real first and last name. Then, at the dawn of the new millennium, they suddenly threw all that **** out the window and started writing mortgages on the backs of napkins to cocktail waitresses and ex-cons carrying five bucks and a Snickers bar.

And what caused the huge spike in oil prices? Take a wild guess. Obviously Goldman had help — there were other players in the physical-commodities market — but the root cause had almost everything to do with the behavior of a few powerful actors determined to turn the once-solid market into a speculative casino. Goldman did it by persuading pension funds and other large institutional investors to invest in oil futures — agreeing to buy oil at a certain price on a fixed date. The push transformed oil from a physical commodity, rigidly subject to supply and demand, into something to bet on, like a stock. Between 2003 and 2008, the amount of speculative money in commodities grew from $13 billion to $317 billion, an increase of 2,300 percent. By 2008, a barrel of oil was traded 27 times, on average, before it was actually delivered and consumed.
