Meet James. James bought a house. It cost him $150,000, of which $30,000 had come from his own savings, leaving him with a $120,000 30-year fixed-rate mortgage from the WTF Bank, with a final cost (after 30 years of interest) of $200,000. Now, up until the ’80s, a mortgage was just a mortgage. Banks would lend the funds and profit from interest as the mortgage is paid back.
Not so today. James’s $200,000 mortgage was packaged up with 1,000 other mortgages into a £180 million MBS, (mortgage backed security), and sold for an immediate gain by WTF Bank to Privet Asset Management, a hedge fund. Privet then placed this MBS with Sacks of Gold, an investment bank, in return for a $18 billion short-term collateralised (“hypothecated”) loan. Two days later Sacks of Gold faced a margin call, and so re-hypothecated this collateral for another short-term collateralised $18 billion loan with J.P. Morecocaine, another investment bank. Three weeks later, a huge stock market crash resulted in a liquidity panic, resulting in more margin calls, more forced selling, which left Privet Asset Management — who had already lost a lot of money betting stocks would go up — completely insolvent.
You should be. This is of course a fictitious story. But the really freaky thing is that this kind of scenario — the packaging up of fairly ordinary debt into exotic financial products, which are then traded by hundreds or even thousands of different parties, has occurred millions and millions of times. And it is extremely dangerous. When everybody is in debt to everybody else through a complex web of debt one small shock could break the entire system. The $18 billion debt that Privet owed to Sacks of Gold could be the difference between Sacks of Gold having enough money to survive, or not survive. And if they didn’t survive, then all the money that they owed to other parties, like J.P. Morecocaine, would go unpaid, thus threatening those parties with insolvency, and so on. This is called systemic risk, and shadow banking has done for systemic risk what did the Beatles did for rock & roll: blow it up, and spread it everywhere.
