The Credit Crisis Could Be Just Beginning

The more loans that were sold, the more they could use as collateral for more loans, so credit standards were lowered to get more paper out the door -- a task that was accelerated in recent years via fly-by-night brokers that are now accused of predatory lending practices.

Buyers of these credit risks in CDO form were insurance companies, pension funds and hedge-fund managers from Bonn to Beijing. Because money was readily available at low interest rates in Japan and the U.S., these managers leveraged up their bets by buying the CDOs with borrowed funds.

So if you follow the bouncing ball, borrowed money bought borrowed money. And then because they had the blessing of credit-ratings agencies relying on mathematical models suggesting that they would rarely default, these CDOs were in turn used as collateral to do more borrowing.

In this way, Das points out, credit risk moved from banks, where it was regulated and observable, to places where it was less regulated and difficult to identify.

Turning $1 Into $20

The liquidity factory was self-perpetuating and seemingly unstoppable. As assets bought with borrowed money rose in value, players could borrow more money against them, and it thus seemed logical to borrow even more to increase returns. Bankers figured out how to strip money out of existing assets to do so, much as a homeowner might strip equity from his house to buy another house.
