The Federal Finance Housing Agency needs to be vigilant in its continued oversight in its management of Fannie Mae and Freddie Mac, according a report from the Office of the Inspector General. Because the FHFA’s actions aren’t subject to judicial review, the OIG said its oversight of the FHFA conservatorship actions and processes “is critical to safeguard taxpayer dollars and ensure that the FHFA is fulfilling its statutory duties.” In the new white paper, the OIG said Congress vested the FHFA with “sweeping powers” as conservator to potentially control every decision the enterprises make.In 2014 alone, the FHFA flexed its muscle to take more than 750 conservatorship “actions” against Fannie and Freddie.
