The global financial crisis of 2008 was primarily caused by the actions of the first world’s banks. There were a number of other significant players, notably the credit ratings agencies and the government structures responsible for financial system oversight, but it was the banks’ rapacious addiction to skimming and structuring for higher short term profits, with no addition to productive output, which led the world headlong into the crisis.
The banks required many billions of dollars of public assistance to remain solvent. Yet it is the same firms which now seem to be the first to recover to pre-crisis profitability. Perhaps not surprisingly little or nothing has changed in the conduct of their business.
In this light I thought it worth reproducing a short GFC essentials which I wrote in October 2008 in response to a number of requests for some kind of explanation of the severe downturn.

(October 2008)
The crisis has been primarily caused by two separate banking practices. The two are related, but could have occurred independently.
· credit was mispriced
· securitisation alchemy
Mispriced Credit
A bank can borrow at say 5%, and cover costs by lending at say 7%. Assume all borrowers have the same credit worthiness. The bank knows that statistically 1 in a 100 of its borrowers will fail, so it needs to add a credit spread on top of the 7% - so the bit of extra profit it earns on the 99 good loans covers the loss of the bad loan – so it lends at say 9%.
Assume this is a fair number. We would say the credit spread is 200 points.
In good economic times, with banks competing to make more loans, there is a temptation to cut the credit spread – reducing your headline loan rate. If you ignore or understate the credit risk (provisioning) in your consolidated accounts you can fool yourself into believing the loan book is still profitable even at very reduced credit spreads.
But the losses must be realised. Statistics don’t lie. Over time a percentage of the loans will fail. Many of the good/profitable (management bonus paying) loan books were in fact bad/loss making loan books.
The Austrian Economists wrote about it in the late nineteenth century – …if credit is priced too cheaply, leading to an increase in economic activity, it will eventually be realised in credit losses and reduced economic activity…; i.e. a recession.
So, credit pricing is now going through a massive (over)correction phase.
Securitisation Alchemy
In the old days the bank borrowed money – say from depositors, say $10mill. This is a Liability on the bank balance sheet – it owes the punters the money.
It then lends the money, as say, 20 x $500k mortgages, to a different set of punters. These loans are an Asset on the bank balance sheet.
To make more loans it needs to raise more deposits, or borrow more money. One way to borrow more money is to issue a bond. Governments, banks, other corporates do this all the time.
Another way to raise more cash is to sell Assets. The bank has Loans as its Assets. It decides to sell them, to take the cash now, and to use that cash to make more loans. That is, it effectively packages the loans as a type of bond or ‘security’ and sells it into the market place. The returns on the loans no longer directly affect the bank, who now merely administer the loans, and pass on the proceeds (mortgage repayments) to the bond holders.
The bank continues to recycle loans in this fashion.
Then non-banks got in on the action, borrow from a bank, make some loans, package them up as a security, sell it into the market – perhaps to another bank – and go around again.
But how much cash do we get when we sell these mortgage backed securities? The market has some sense of comparative value, so it discounts the bond by the perceived credit worthiness of the underlying mortgage holders. Is there any way we could get a higher price?
Lets say, for a given mortgage backed security we rate all the mortgagees as a ‘B’, and lets say, statistically, 5 in 100 B’s will fail (default). How can we get more cash for these B rated mortgages? Magic – turn most of them into A’s! Enter the Collateralised Debt Obligation (CDO) or tranched debt instrument.
We know 5 out of 100 will fail, so it follows 95 of the B’s will succeed. Those B’s will effectively perform as well as the A’s. So, lets split our “100 mortgages asset” into one group (tranche) of 90, and one group of 10 (the bottom tranche). The rules of our fancy CDO bond say that any defaults hit the bottom tranche first. So, statistically, the top tranche is protected from any defaults. Viola! we have some ‘A’ rated paper. And the Ratings Agencies – S&P etc – bought the argument. So, the bank can sell 90% of its B rated loans for a much higher (A style) price, more than compensating for the much lower (C style) price it has to accept for the risky (but high yielding) bottom tranche.
So, while credit was getting cheaper, and there were more loans, and more upward pressure on asset (house) prices, there was also a flood of mispriced mortgage securities being bought, and often pledged as collateral on more low credit spread loans, and so on.
All Comes Unstuck
Part of the argument the banks could use for lending on such low credit spreads, was that it didn’t really matter if someone defaulted. You could sell their house to get your money back.
But as the number of defaults began to increase, so did the downward pressure on house prices. Banks suddenly got a little nervous and began tightening (increasing) their credit spreads. This starts to dry up the amount of available loans to potential house buyers putting further downward pressure on prices. Banks panic and bring forward foreclosures exacerbating the problem.
The supposedly safe ‘A’ part of the dodgy bonds start to get hit. There are trillions of dollars of these things held all around the world from local councils to pension funds to banks themselves. As their value is marked sharply down, the holders of the bonds also see their credit spreads jump sharply up. Even if they can find someone willing to lend to them, they probably can’t afford the repayments.
Without short term liquidity, the system starts to freeze up. Organisations with high debt levels and/or dodgy asset valuations begin to go under (e.g. Lehman’s), further compounding the problem.
The conscious decision to misprice credit – both directly and via the CDO smokescreen - is directly responsible for the current drama.

Postscript (March 2010)
Bank management paid themselves billions of dollars in ever increasing cash bonuses in the decade leading up to the GFC. This was supposedly due to out performance, a reward for great efficiency and superb use of Bank capital.
The GFC proved it to be a croc. The profits were not real. The return on capital was not real. The profits were based on flawed valuation methodologies. The cash bonuses were not earned and have now been effectively funded by public subsidy.
Just two years since the GFC was getting into full swing and we seem to be returning to exactly the same scenario – the subsidised financial corporations are again ready to pay themselves large bonuses.
The lack of direct government action, while regrettable, is somewhat predictable given the relatively short timeframe, and the domiciles of the major culprits. But the force of public outrage should be such that it can shame these institutions to behave in a socially responsible and equitable manner.
Act now.
