In tandem with its efforts to build a common securitization platform, the Federal Housing Finance Agency provided an update on its progress in developing a single security for the GSEs last week. “The single-security project is intended to improve the overall liquidity of Fannie Mae and Freddie Mac mortgage-backed securities, and lower costs for borrowers and taxpayers,” said the FHFA. The recent update primarily focused on the decisions it made based on the 23 response letters it received and dialogue the agency had with industry leaders after initiating a request for input last year. While representatives from the Federal Home Loan Banks suggested that the FHLBank system become an eligible issuer of single securities, the FHFA declined that proposal.
