From the WSJ: S&P Puts Mortgage-Backed Securities on Downgrade Watch (ht Bob_in_MA)

Standard & Poor's Ratings Service on Monday placed its ratings on $552.8 billion worth of U.S. first-lien Alt-A residential mortgage-backed securities issued between 2005 and 2007 on watch for downgrade, saying it sees an increase in losses from the transactions issued in those years.

S&P said it believes continued foreclosures, distressed sales, an increase in carrying costs for properties in inventory and more declines in home sales will further depress prices and lead to higher losses.

The beat goes on.
