The argument for a bail out

Seems clear we are trading short run gain for long run pain. But here is a clearly articulated argument for doing so.

Banks can lend to consumers and investors about 12 times their capital base. If they have to write off 20% of their capital because of losses, that means they either have to sell more equity or reduce their loan portfolios. As an example, for every $1,000 of capital, a bank can loan $12,000 (more or less). If they have to write off 20% ($200), they either have to sell stock to raise their capital back to $1,000 or reduce their loan portfolio by $2,400. Add some zeroes to that number and it gets to be huge.

And that is what is happening. At first, banks were able to raise new capital. But now, many banks are finding it very difficult to raise money, and that means they have to reduce their loan portfolios. ...

I don't want to name names, as this letter goes to about 1.5 million people and I don't want to make problems for some fine banking names; but there is a silent bank run going on. There are no lines in the street, but it is a run nevertheless. It is large investment funds and corporations quietly pulling their money from some of the best banks in the country. They can do this simply by pushing a button. We are watching deposit bases fall. It does not take long. Lehman saw $400 billion go in just a few months this summer. Think about that number. Any whiff of a problem and an institution that is otherwise sound could be brought low in a matter of weeks. And the FDIC could end up with a large loss that seemed to have come from out of nowhere.
