WASHINGTON -- The U.S. government has filed civil charges against Standard & Poor's Ratings Services for improperly giving high ratings to toxic mortgage bonds before the financial crisis.
It is the government's first big enforcement action related to a credit rating agency's actions in the lead-up to the 2008 crisis. Ahead of the filing late Monday, S&P had said it expected to be charged but denied any wrongdoing and said any lawsuit would be without merit.
So what's the big deal? And what did the bond-analysis shops have to do with the financial crisis?
Here are some questions and answers about the expected charges against Standard & Poor's:
Q: The government brings civil charges against financial companies all the time. What's so important about this case?
A: These are the first federal charges against one of the credit rating agencies that are widely blamed for contributing to the financial crisis that brought about the worst recession since the Great Depression.
The crisis crested when a bubble in U.S. home prices popped, making it more difficult for people to refinance their mortgages and setting off a wave of defaults and foreclosures.
Wall Street banks had created trillions of dollars' worth of investments whose value was based on the value of those mortgages. The investments were spread through the financial system. Without rating agencies, none of that would have been possible.
Q: If they didn't create or sell the investments, why are credit rating agencies blamed for their proliferation?
A: Agencies like Standard & Poor's gave high ratings to complex pools of mortgages and other debt. That gave even risk-averse buyers the confidence to buy them. Some investors, including pension funds, can only buy securities that carry a high rating. In short, credit ratings provided by S&P greased the assembly line that allowed banks to push risky mortgage bonds out the door.
When they realized the bonds were worth far less than previously thought, in late 2007, Standard & Poor's and other agencies lowered the ratings on nearly $2 trillion in mortgage securities. The downgrades helped spread panic because holders of the bonds and any potential buyers of them no longer knew their value.
The government says S&P knew the bonds were risky, but gave them artificially high ratings in a quest for higher revenue and greater market share.
