Though I am currently much more concerned with my personal situation of job search

I will take few minutes to explain people here (an perhaps few ones outside) my view on the magnitude and intractability of modern financial crisis.

As Chairman Bernanke recently said to Congress the lending process in the US is provided half through commercial banks' credit and half through securitization (read CDOs).

I repeat: half of credit is coming through securitization channel. And it is this half that creates the most difficult problem. As was pointed out recently, the core of CDOs pricing is performed based on David Li's formula, which allowed a huge expansion of securitized products. And now his model is considered to be corrupt in the sense that model doesn't match the market reality.

So, we are in a very difficult situation. The credit market is not functioning (since securitized products can't be priced reliably anymore), we can't go back to pre-securitization stage (it's like going to pre-computer stage after you computerized the whole country), and we can't go forward (since Gaussian copula is not trusted anymore). Such situation is called "zugzwang" in chess -- any move will only impair the situation.

Objectively speaking, it looks like a "Chinese sabotage."

Chinese guy came to America, and gave Americans nice formula. "Stupid" Americans used it and created a whole bunch of financial products, which eventually failed. And they don't know how to fix the situation now (and Chinese guy is now back to China where he works for Chinese government currently). Of course I don't believe that it had been done deliberately.

But one can see here the hand of Providence to destroy the American Empire. And another one can say that we have a big theoretical challenge ahead of us to solve the situation.

P.S. Actually you can't say that it's the David Li's approach that failed. He just took CreditMetrics empirical approach, generalized it and formalized it from the mathematical point of view.

P.P.S. Former Chairman Volcker was calling to copy the Canadian oligopoly approach (where 5 banks control the whole country). I don't think it will help here. It will stiffen the financial system and just cause the world economic stagnation IMHO.

Look at/examine the *political* climate at the time that led to the circumstances that enabled CDOs to come into existence. If you don't have a suitable incubator your formula will never come into existence.

What do you think? For instance hypothetically assume that there is no CDO in the market and also another trouble like CDS has not been invented. Do you sure that we do not observe the Crisis? Though it looks premature to consider conditionals like what will be if �
I heard to day a quite profound comment on the radio unfortunately I did not hear the beginning. The thought was that people institutions and banks will not spend the additional money they will hide them. In 2-3 years when the real economy will start to recover all accumulations will over flood the market that will lead us to huge inflation. It sounds pretty much reasonable.
For a current moment while $$ still grows and correspondingly others weakening and there is no other good real news then one could patiently wait inverse movement that actually could be more sharp. Then� people probably will begin to talk about other financial problems and forget about structuring at all. Now the subprime problems completely disappeared from discussions. More actual is to talk about regulations. I am curious about what a reasonable world class solution could one expect from the person who could not note the approaching Lehman troubles? One of the modern regulation problems that people who make a decisions are match for the plain periods of economic development and looks rather inexperienced in the current period.

Cuchulainn, why did you delete your question? But I will answer it.

Since David Li used CreditMetrics approach here comes two outcomes,

1. One can't blame him for losses because it's not purely "his" model.

2. It explains why industry easily adopted "his" model.

I guess that crisis would be less severe.

Actually it's the same problem of wrongful pricing of CDOs (read Gaussian copula).

People made billions on their proper understanding of economic situation. Why would one with "knowledge" give it away for free? I personally probably wouldn't ...

That's not clear to me at all.

Yes, CDOs did facilitate a lot of the flows of capital into subprime mortgages in the US, but can CDOs explain all that has happened such as the bankruptcy of Iceland, the housing bubble in many parts of Europe, or excessive lending of fx-rate adjustable debt to subprime countries in the Eastern/Central Europe? Nor do CDOs or any other type of magical mathematical incantations explain the asset bubbles of the dotcom era, the Japanese real estate bubble, or the roaring 20s, etc.. I see CDOs as proximate causes, not ultimate causes. Even if Li had never created the copula equations, some clever folk would have crafted some form of nifty debt/equity structure for pooling mortgages and selling that. No doubt we'd have seen some form of REITs, SPACs, or HF entities.

All we need for a good asset bubble is a mechanism for leverage and enough years of steady price appreciation to convince everyone that prices can only up. Erroneous equations such as Gaussian copula are neither necessary nor sufficient to cause global financial crises.

fully agree. This crisis is caused by too much leverage.

The precise mechanisms are irrelevant - next time there will be different mechanisms but the underlying cause (over leverage) will be the same. Anyone who has any knowledge of financial history should know this. I don't understand why this is so hard for people to understand.

1 and 2 are clear; but that was not my point. How did it get so far to enable such models to be accepted in the first place?

The first law of the financial business: you paid for what you are said. That means that you are paid in order to make money your Company or others. The problem of weather it is good or bad, correct or not is the second or lower kind of problems. If you have another approach you can wait. It might be your turn comes out.
CDO looks rather the way how internal problems came into surface. The underlying main problem is the wish to increase capitalization institutions or countries by using derivatives. I also think that CDS spread is the very important characteristic though I think that its value should be converted say into a linear decreasing function. The losses at the beginning are more painful than at the end.
The money from this market sooner or later begins to leak out into other markets. And the prices will grow up for some saturated period then will drop down. And cycle will be repeated again. A technical problem is globalization of the underlying. Companies and countries have used the same underlying securities. Though Crisis first appeared in US the particular place of the US is that its huge debt is hold by others which should be found the way to facilitate its dependence from US debt but as 0onehas seen do not find the appropriate way. As a conclusion all other countries began to use their accumulations.

I doubt that any Polish bank ever bought a single bespoke CDO tranche.

And too much over-capitalisation in few hands. When those who are over-capitalised andover-leveraged and all making the same bets like sheep, why would anyone expect anything other than a short period of glorious market manipulation with big bonusses for a few followed by social disaster.
