The world is changing in a very major way. Oil is in short supply, and this shortage is likely to get larger in the future. The pressure of short supply and rising prices adds a systematic bias that the financial community is not recognizing. This bias has as its basis the fact that it is becoming more and more difficult for both people and businesses to pay back loans, because of the rising costs of oil and food. This situation cannot be expected to go away. In fact, it is certain to get worse in years ahead, as oil supplies become tighter.

Besides the systematic bias, there is also a systemic risk, arising from the interconnectedness of all of the parts of the economy. This was well described in a post a few days ago called The Failure of Networked Systems. One of the issues in systemic risk relates to the financial system itself. If one party in the financial system fails, it increases the likelihood that other parties in the economic system will fail as well.
