A U.S. Securities and Exchange Commission investigation into credit-rating companies found the firms improperly managed conflicts of interest and violated internal procedures in granting top rankings to mortgage bonds.

A 10-month review of Moody’s Investors Service, Standard & Poor’s and Fitch Ratings found analysts contributed to fee discussions and weighed losing clients over certain ratings, the Washington-based SEC said in a report released today. Employees also cast doubt on the quality of some ratings, the SEC said, declining to link firms to specific findings.

“We uncovered serious shortcomings at these firms,” SEC Chairman Christopher Cox said today at a news conference. “When there were not enough staff to do the job right, the firms sometimes cut corners.”

Pension and money-market funds bought AAA-rated securities backed by mortgages to the riskiest borrowers because they offered higher returns than government bonds with the same ratings. In many cases, credit raters were paid by investment banks selling the bonds, prompting regulators and lawmakers to question their independence.

The SEC report describes an e-mail in which an analyst refers to the market for collateralized debt obligations as a “monster.”

“Let’s hope we are all wealthy and retired by the time this house of cards falters,” said the e-mail, which was sent Dec. 15, 2006, to another analyst at the same firm.

Mike Burnick at Sovereign Society says,

A look inside one of these [subprime mortgage] bonds tells a frightening tale. A US$80 billion sub-prime asset-backed bond issued by Deutsche Bank in 2005 is still rated AAA by S&P and Moody’s. Yet, 18% of the mortgage loans in the security are in foreclosure.

Additionally, lenders have already seized 15% of the properties underlying the loan values for this security. Another 10% have been delinquent for more than 90-days.

Another Morgan Stanley Capital sub-prime mortgage-backed security has credit support of 64% relative to the number of delinquent mortgages loans in the pool. But the credit should be at least twice the delinquent mortgages to maintain a top rating.

Why This Junk Isn’t Rated As “Junk”

Technically, much of this so-called triple-A rated debt should have been downgraded long ago. So why hasn’t it? The simple answer is: Fear of too much “collateral damage.”

According to Bloomberg, “Financial firms own high-grade collateralized debt obligations, which package securities such as mortgage bonds and slice them into pieces with varying risk. As the underlying mortgage bonds are downgraded, those securities will also lose their ratings and tumble in value.”

There’s a huge potential “contagion” effect that would ripple through the financial system if Moody’s or Standard and Poor’s dared to downgrade these shaky sub-prime credits across the board. For instance, a bank holding US$100 million of AAA-rated sub-prime bonds needs just US$1.6 million in capital backing such a highly rated credit. – that’s a lot of leverage. And such leverage is fine, as long as the bonds remain triple-A rated.

Should the bonds get downgraded to below investment grade however, under global accounting rules, a bank must put up additional capital. In fact, it would take US$16 million in capital to back US$100 million in non-investment grade bonds.

That’s 10 times as much capital required in the event of a credit ratings downgrade. Wall Street just doesn’t have that kind of extra capital lying around. Bear Stearns found this out the hard way over the weekend. That’s why I expect the major ratings agencies, perhaps abetted by the Treasury Department and the Fed, to continue covering-up the true health of US$650 billion in outstanding sub-prime bonds.

Burnick concludes that:

At the risk of sounding like an alarmist, I just have one question. What happens to confidence in the U.S. financial system (not to mention the dollar) when people wake up and realize these fairy tale markets (held up by fantasy ratings) turn into a nightmare?

The Fed is merely monetizing Wall Street’s mistakes yet again, while leaving future generations of taxpayers with an even bigger tab to settle, and higher future inflation to fight.

But there’s just no time for such ponderings now, we’re in the midst of a full-blown financial crisis after all. Damn the financial torpedoes, full speed ahead with the monetary printing press.
