For the world of mortgage finance, that is the paramount question. It is essential to the success of any efforts at reviving the secondary mortgage market on a sustainable basis with and without a federal government role. Restored trust is essential in the near and mid-term to restarting the private-label mortgage-backed securities market, which collapsed in August 2007. In the fourth quarter of 2008, the government share of mortgage originations -- FHA, Department of Veterans Affairs and the government sponsored enterprises -- stood at 92%, according to Inside Mortgage Finance. Some observers believe that the securitization market, like bank lending, is not going to revive and prosper until banks and other institutions and firms that hold those assets can dispose of them at true market prices. Mortgage lenders that operate under the private securitization model for originating new loans would have to sell them into the secondary market for a loss.
