All fall down?

Huge new problems in the capital markets?
The threat of such a financial domino effect looms large. Moody’s, a credit-rating agency, has signalled that it might downgrade the AAA-ratings of two of the biggest bond insurers, MBIA and Ambac, in the near future. On Friday January 18th, Ambac said that it had dropped a plan to raise $1 billion of new equity capital to preserve its rating—making futher downgrades even likelier. In response, Fitch, another rating firm, cut Ambac's rating.
MBIA, which recently managed to raise $1 billion of new capital on top of another billion that it received from Warburg Pincus, a private-equity firm, will almost certainly need even more money if it is to preserve its AAA-rating. ACA Financial Guaranty Corporation, another insurer, is in even direr straits. In December its single-A credit rating was cut to junk status. The firm begged its trading partners to give it more time to sort out its problems. But by Friday it had still not come up with a rescue plan. The state insurance regulator of
Bond insurers in effect “lend” their top-notch ratings to lower-quality debt, raising its value in the eyes of investors. Any cut in those ratings may make it impossible for the bond insurers to take on new business and would reduce the value of the securities they have already underwritten. Such cuts are now a distinct possibility because the insurers have underwritten billions of dollars of mortgage-backed securities, including those notorious collateralised-debt obligations (CDOs) that have now gone sour.
On Wednesday Ambac announced a $3.5 billion writedown—as well as the ousting of its chief executive—$1.1 billion of which was related to CDOs. The insurers’ exposure to these and other exotic products is a huge multiple of their flimsy capital bases—and the chances of them having to cover claims has soared as the economy has slowed. Small wonder, then, that their share prices plummeted this week—proving that the market has already decided they no longer deserve such lofty ratings and creating a vicious downwards spiral. Ambac’s falling share price has severely dented it chances of raising fresh capital.
There are already signs that the insurers’ woes are contagious. On Thursday Merrill Lynch wrote down $3.1 billion on debt securities that it had hedged with ACA and other bond insurers. Other banks have also made writedowns to reflect their lack of confidence in ACA’s ability to meet its commitments. The full extent of the “counterparty risk” banks face in dealing with bond insurers is only now becoming apparent Jamie Dimon, the boss of JP Morgan Chase, has said that the fallout from the bond-insurer crisis could be “pretty terrible” for the debt markets. If a big insurer such as Ambac or MBIA were to take a tumble, that could look like an understatement.
