Fannie Maes and Freddie Mac conservatorships have caused the governments involvement in the mortgage market to balloon to unhealthy proportions since the two GSEs entered government conservatorship in 2008, creating far-reaching effects on the private sector, crowding out potential capital and blocking real market competition, according to the Mortgage Bankers Association.The fix, the MBA suggests, calls for the Federal Housing Finance Agency to require the two GSEs to accept loans with deeper levels of credit enhancement in exchange for reductions in guaranty fees and other loan-level charges.By requiring the GSEs to offer programs such as up-front risk sharing between lenders and the GSEs, the FHFA would be taking a big step in the right direction, said MBA President and CEO David Stevens. Ultimately, this would put private capital, not taxpayers, in the first loss position and would allow lenders of all sizes to compete, driving down costs for borrowers.
