The International Monetary Fund proposed that Fannie Mae and Freddie Mac merge into a single enterprise. The IMF discussed ideas that it said could help stabilize the mortgage finance system in a working paper published late last month. The global Washington, DC-based organization said the GSEs should combine forces “as quickly as possible.” And, “Until this happens they should be forbidden to compete for business on the basis of price.” “The GSE regulator should be tasked with monitoring the enterprises to ensure consistency on this basis,” said the author of the paper, Richard Koss. He believes that the housing finance system is unnecessarily complicated, with Fannie and Freddie having selling guides of 1,408 and 2,303 pages, respectively.
