It’s only a matter of time before the remaining big bank defendants settle lawsuits filed by the Federal Housing Finance Agency over billions in non-agency mortgage-backed securities sold to Fannie Mae and Freddie Mac in the years leading up to the housing crisis, predicts a legal expert. Last week, Bank of America agreed to a $9.3 billion settlement that covers its own dealings as well as those of Countrywide Financial and Merrill Lynch, which it acquired in 2008. The agreement covers some $57 billion of MBS issued or underwritten by these firms.
