What Caused the 2008 Financial Crisis and Could It Happen Again?
I still don't understand the cause of the financial crisis. I try to wrap my head around it.
What does this mean?
The
Gramm-Rudman Act was the real villain.
The Gramm-Rudman-(Hollings) Act was budgetary control legislation enacted back in the 1980's which, as far as I know, had nothing to do with derivatives, could be mistaken on that but I don't think so.
I would say that the easiest way to think about is this …. You had a situation where you had a glut of capital (globally) looking for low risk, fixed income investment, normally this type of capital gravitates to sovereign debt instruments (especially U.S. Treasury Bonds), however the U.S. Federal Reserve (in the form of Alan Greenspan) had been sending signals that the Fed anticipated that U.S. Treasury Yields would remain low and stagnant for the foreseeable future (making them less attractive investments).
This prompted Wall Street investment banks to begin looking for attractive alternatives to sell to these investors, what they found was a business that Fannie Mae and Freddie Mac had been in for over a decade, namely buying and securitizing (essentially slicing them up and combining them into risk tranche's) mortgages, then re-selling them to investors as MBS (Mortgage Backed Securities).
Once Wall Street got involved the demand for MBS products skyrocketed which in turn increased the demand for the underlying mortgages (they need mortgages to create MBS), so investment banks pushed mortgage brokers and lenders to create more and more loans. When they ran out of highly qualified mortgage borrowers, they had no choice but to start going down the chain and lending to less qualified buyers to meet the MBS demand.
This had predictable effects:
Less qualified borrowers = More risk
More competition in the MBS market = more market manipulation (i.e. investment banks and rating agencies lying about the real risk)
More home buyers competing for a limited supply of homes = Higher Home Prices
You combine these factors and what you get is a vicious cycle of reckless risk taking by financial institutions and borrowers, basically a big casino where the banks are playing with other peoples money while the little guy is footing the bill by getting loans they can't afford on houses that are overpriced.
That's a
very simplified explanation but I think it paints a fairly accurate picture of the core of the problem, there were a host of other factors as well (Opaque Risk Chains (CDS), government created incentives and moral hazard, etc,,,) but hopefully you get the picture.
