A prolonged conservatorship coupled with a change in leadership at the Federal Housing Finance Agency could shift priorities for Fannie Mae and Freddie Mac, according to the Government Accountability Office. The GAO said a potential priority change for Fannie Mae or Freddie Mac would only send mixed messages, creating uncertainties for market participants and hindering the development of the broader secondary mortgage market. In its 2017 biennial report released this month, the GAO discussed actions that need to be taken in order to resolve the federal role in housing finance. The need for leadership commitment by Congress and the administration to reform the system was one of the primary themes.
