Newsflash: The GSEs have been under Executive Branch Regulation since at least 1992.
Until Paulson put them in conservatorship, the GSEs were regulated by HUD and OFHEO - both part of the Executive Branch.
From OFHEOs FAQ:
How is oversight of Fannie Mae and Freddie Mac divided between OFHEO and HUD?
The Federal Housing Enterprises Financial Safety and Soundness Act of 1992 created a regulatory oversight structure for the housing government-sponsored enterprises of Fannie Mae and Freddie Mac. The regulatory oversight was divided to address two functions – their financial safety and soundness and their affordable housing mission. The financial safety and soundness regulation is vested in the Office of Federal Housing Enterprise Oversight (OFHEO). OFHEO implements, monitors and enforces capital standards for Freddie Mac and Fannie Mae.
Effective January 1, 2005, HUD established new and increasing affordable housing goal levels for the GSEs for the years 2005 through 2008. These goals require that a certain percentage of the mortgages purchased by Fannie Mae and Freddie Mac support financing for housing low – and moderate – income families.
