As we have seen over the last year or so, the credibility of rating agencies is hardly what we expected. Thinking about it now, does not make it difficult to understand why the credibility is not necessarily in the investor's interest.
Some problems with rating agencies for investors:
1) Credit rating agencies compete with each other to win business. Price in this case will not make a difference for companies who are listed on the stock market or companies who wish to issue bonds or other financial instruments.
2) Companies will want their ratings to be as good as possible, regardless the real risk involved, similarly investors do not want ratings to decrease as that would mean they may need to restructure their investment portfolio, involving costs of exiting and entering new investments.
3) Rating agencies are not responsible for the ratings they give which lets them off the hook if something does go wrong, such as in the case of Lehman and many other banks.
Some thoughts towards solutions:
1) Agencies will need much tighter regulations in terms of how to assess the risk of a company. This will be hard as they look at the insights of companies which could be different in each case. It could also be subjective, allowing for different views.
2) There is only room for one credit rating agency. If they do not need to compete for sales and every company must be rated by the same agency, the problem of releasing better ratings simply because they need to, would be solved.
3) Agencies would have to be held responsible for what they rate. The US congress released some internal communication yesterday between some employees of an agency held over MSN messenger:
"That deal is ridiculous," the colleague, Rahul Shah, wrote.
"I know right ... model def. does not capture half of the [risk]," Ms. Mooney replied.
"We should not be rating it," Mr. Shah said.
"I know right ... model def. does not capture half of the [risk]," Ms. Mooney replied.
"We should not be rating it," Mr. Shah said.
"We rate every deal," Ms. Mooney wrote. "It could be structured by cows and we would rate it."
It is not possible to have such irresponsible employees being in charge of ratings when thousands of investors depend upon it.
Clear regulations will need to be in place for rating agencies. If this can not be done it is the authorities task to educate investors on how ratings are done and what regulations exist to avoid them from believing things that do not exist. If authorities are going to regulate the rating agency, I believe it is their job to do it in detail and not simply come up with some ideas and allow agencies to do what they want.
