The Wall Street Journal on Friday said:
"The turmoil on Wall Street is beginning to rock a foundation of the financial system: the ability of institutions to make good on their many trades with one another.
"Today, a struggling bond insurer, ACA Financial Guaranty Corp., will ask its trading partners for more time as it scrambles to unwind more than $60 billion of insurance contracts it sold to financial firms but can't fully pay off, according to people familiar with the matter. The contracts were intended to protect Wall Street firms from losses on mortgage securities and other debt they own.
"The problem is that the insurer itself is teetering - with repercussions across the financial world."
But that's not the scariest part. According to a fairly well-known financial analyst, ACA Financial is a small-time player. However, he says that the world's two largest bond insurers are also collapsing.
If he's right, the effects on the bond market may be even more serious than the mortgage and stock market crashes.
