The Federal Housing Finance Agency should enhance its supervision of Fannie Mae, Freddie Mac and the 12 Federal Home Loan Banks by taking better advantage of the FHFAs call report system, a recent audit has concluded. The FHFAs Office of Inspector General report noted last week that despite requiring the GSEs to enter data into the CRS, the Finance Agency has not optimized its use of the system to enhance oversight. Two FHFA supervisory divisions rarely use CRS in their analysis and oversight of the enterprises, explained the OIG audit. Instead, they receive routine submissions of loan-level data and standard management reports containing relevant metrics and data.
