Summary:
For economic growth we people to take risks by lending money.
For long term stability we need banks that don't go bankrupt.
Thus we need banks to pass on the default risk.
Details:It seems that the word 'banker' sounds like a swear word more-so now then ever before. Banker bashing is a popular pursuit in blogs and newspapers. But seldom do we hear the view from the inside, so let me try to start to remedy that.
Banks are full of regular people, who can show kindness and compassion, particularly to friends and family. They will hold open the door open for a little old lady, but when it comes to large sums of money, they will be, for the most part, very selfish. It is reasonably rare for individuals or firms to give more than 1% in truly charitable donations and the giving that is done is often used as a form of relatively cheap PR work.
Overall I think it is fair to say that banks are selfish institutions, full of selfish individuals. People just like me. In our desire for money we are very much like other groups. In our defence I would say that we are perhaps more open about aims than some. For example politicians frequently claim that they are motivated by a desire to do go and to help others, but their actions are much more consistent with a group whose primary motivation is a lust for power.
In banks, the executive boards have some significant power, but it is not absolute. Ultimately they are accountable to share-holders, who do from time to time demand the sacking of the board.
Suppose, back in 2004, a board member of a major bank were to present to the board the suggestion that they seriously reduce the credit exposure of the bank, which would drastically reduce risk of bankruptcy and indeed the profit of the bank. The board would know well that if they were to take up this suggestion then the share-holders would have them all sacked. If their competitors are making billions by taking large risk, then they are very heavily pressurised to do the same.
Roughly speaking, businesses work for the benefit of the share-holders. They take risks to generate profit. Outside of banking, firms go bankrupt reasonably frequently. Only a tiny fraction of firms that were in operation in 1900 were still going in some shape or from in 2000, without having experienced a bankruptcy and bail-out at some stage.
It turns out that in fact banks have good longevity compared to pretty much any other industry.
However, if we want any form of economic growth, then we need there to be risk-takers. We need to allow firms the right to risk bankruptcy. However suppose we say that the collapse of a retail bank is too devastating for an economy for a government to allow, then we cannot let banks take much risk at all. Any time money is lent there is a risk. So, if we absolutely can't let the banks go bust, then we need to have other risk takers. One solution would be just to let the banks just be intermediaries, not wear-housing the default risk, but rather passing it on. Hedge funds have the potential to be very very helpful to an economy, if they can be encouraged to take credit risk. If they are paid enough of course they will.
Individuals with deposits in banks could also be paid to take on some additional risk. For example an investor could be offered the following:
Choice 1:
Lock away 100,000 Euro for 1 year in super-safe bank and you'll get 1% interest.
Choice 2:
Lock away 100,000 Euro for 1 year and you'll get 6% interest, subject to Ryanair not defaulting on any of its debts. If Ryanair defaults, the 100,000 Euro deposit will be converted into a Ryanair bond, with face-value 100,000 euro.
It is clear, it is simple and we can have safe-guards against mis-selling.
The benefits of offering choice 2 to investors are:
1: Ryanair, and companies like it, will be able to raise money more easily
2: Individuals can get better returns on their savings, by choosing to take some risk
3: The safe banks which the government won't let to bankrupt are exposed to much lower credit risk.
Choice 2 above is basically a 'credit default swap'. They are not very popular at the moment, but they have great potential to come back in future.
