FHFA Launches Servicing Project to Watch Counterparty Risk. The Federal Housing Finance Agency has launched what industry officials have labeled a servicing project to keep an eye on all large servicing sales where the underlying collateral is guaranteed by Fannie Mae and Freddie Mac. Sources briefed on the effort said the FHFAis now officially asking that the GSEs get agency approval for any sales of mortgage servicing rights where 25,000 or more in loans are being transferred. This translates into deal sizes of at least $5 billion.
