"(Forget all those derivatives; they are just a fancy way to get more leverage, or to get around regulations limiting leverage.)"

Nick Rowe with an interesting post on Worthwhile Canadian Initiative:

"But we didn’t know how to design a financial system which is robust enough to cope with people making bad decisions. If some people paid too much for their houses, and other people lent them too much money, the result should have been too many houses built, too few other investments built, and a change in the distribution of wealth when house prices went down and loans went bad. But that should have been the end of it, instead of just the beginning."

I agree.

"How do we stop it happening again? Perhaps we can’t. Perhaps a capitalist financial system is inherently prone to crises, and no amount of tinkering can stop it happening again. Since alternative systems are worse (and also crisis-prone in their own ways), perhaps we just have to live with it, wait for crises to happen, then let the government try to patch up the mess. Maybe that answer is right (and 300 years of history tends to support it). But I refuse to accept it. We have to do better."

I agree.

"This financial crisis, like others, has three main components:
  1. A bursting bubble.
  2. Leverage.
  3. Duration-mismatch (borrowing short and lending long).
(Forget all those derivatives; they are just a fancy way to get more leverage, or to get around regulations limiting leverage.)"

I agree with this completely, and so I commented:

"(Forget all those derivatives; they are just a fancy way to get more leverage, or to get around regulations limiting leverage.)"

Thank God you said this. I've been saying this as well, and it's great to find someone who agrees with me.

On the Soros testimony the other day:

"Take for example credit default swaps (CDSs), instruments intended to insure
against the possibility of bonds and other forms of debt going into default, and whose price
captures the perceived risk of such a possibility occurring. These instruments grew like Topsy
because they required much less capital than owning or shorting the underlying bonds.
Eventually they grew to more than $50 trillion in nominal size, which is a many-fold multiple of
the underlying bonds and five times the entire US national debt. Yet the market in credit default
swaps has remained entirely unregulated."

( Agree: but he misses the point. CDS's filled the need, which were investments with less capital. Something else would have worked if they didn't. It wasn't the investment, it was the need which created the investment )

"There are four ways we can try to prevent financial crises:

  1. Prevent bubbles. If central banks had raised interest rates sufficiently high, they could have burst the housing bubble before it got too big. But not all assets were over-priced, and high interest rates would have done harm in the rest of the economy. And this cure also relies on the policymakers keeping their heads while all around them are (in hindsight) losing theirs. Policymakers are people too. And in any case, a real shock could have had a similar effect on average house prices. A financial system ought to be robust to real shocks, as well as to bursting bubbles."
I don't agree with this this. The Fed using rates like this is blunt and damages the whole economy, not simply the one in which bubbles occur.

To be continued in the next post.

Thanks Don! But I don't think we disagree on that last point. I think we are saying the same thing in different words. Your point, about Fed policy being a blunt tool which could only burst a bubble by harming the rest of the economy, is exactly the one I was trying to make (perhaps less clearly).
