About 30 industry trade groups recently called for Congress to refrain from using GSE guaranty fees as a source of funding for highway programs or any other purposes beyond supporting Fannie Mae and Freddie Mac. The letter, addressed to House Speaker John Boehner, R-OH, as well as leaders Nancy Pelosi, D-CA, Mitch McConnell, R-KY, and Harry Reid, D-NV, aims to prevent the government from tapping g-fees to pay for pet projects. G-fees, used by Fannie and Freddie to protect against losses from loans that default, are a “critical risk management tool,” according to the trade groups who say that increasing g-fees for other purposes imposes an unjustified burden on the housing finance system.
