More than $70 billion in tranches from jumbo residential mortgage-backed securities were recently downgraded. Rapidly deteriorating performance on jumbo pools drove the downgrades.
In several recent news releases, including eight today, Moody’s Investors Service announced the downgrades to prime jumbo securitizations.
The New York-based ratings agency explained that its actions were due to “rapidly deteriorating performance of jumbo pools in conjunction with macroeconomic conditions that remain under duress.”
