Description: Political figures and journalists have tended to blame deregulation and greed for the credit crisis. However, we would like to suggest that these were not the primary cause of the credit crisis. The real cause of the crisis was faulty regulation and arrogance. Flawed regulation in the over-reliance on complicated capital models and arrogance in believing that the complex mathematical formula in risk models overcame the limitations on input availability and enabled companies to capture returns that were greater than the cost of capital, have led Wall Street by creating CDOs and similar instruments to repackage risks and take out the systematic excess risk charges as profits, and have also allowed companies to run “prudently” on leverage ratios that were in hindsight over the limit.

Description: Interest rates rose from 2004 through 2007, so adjustable mortgage rates increased and many borrowers fell behind. After home prices topped out in 2006, speculators and some buyers who had overstretched found it impossible to refinance. This caused mortgage insurance claims. Insurers may want to study others’ missteps.

Description: Our current financial crisis has wreaked havoc on the credit markets, the stock market and the entire economy. We must remember that the root cause of this crisis is the collapse of the residential housing market, which has been further exacerbated by the continuing downward housing spiral.
