SAN FRANCISCO (MarketWatch) -- More than half of the mortgage-backed securities downgraded Tuesday by rating agency Moody's Investors Service are tied to home loans originated by units of General Electric Co., Washington Mutual Inc., Fremont General Corp. and New Century Financial.
Moody's cut ratings on 399 subprime residential mortgage-backed securities, or RMBS, and said that it may downgrade another 32 because of higher than expected delinquencies on the underlying home loans.
Standard & Poor's also unveiled big changes to its views on subprime mortgages on Tuesday. The rival agency said that it may downgrade more than $12 billion of subprime RMBS soon.
Many of the mortgage-backed securities targeted by S&P are also tied to loans offered by Fremont, WaMu, GE and New Century.
However, several other subprime-mortgage players were listed by S&P as well, including Merrill Lynch & Co. and its subsidiary First Franklin; NovaStar Financial Inc., Bear Stearns Cos. and Citigroup Inc.
