The Federal Housing Finance Agency’s official watchdog is advising the regulator to apply greater scrutiny to Fannie Mae as it works on a “promising initiative” to shift poor performing GSE loans to more capable financial institutions. This week’s report by the FHFA’s Office of Inspector General found little fault with a controversial transaction last summer between Fannie and Bank of America under the GSE’s High Touch Servicing Program. However, the OIG concluded that there was room for improvement in the FHFA’s and Fannie’s supervision of the program.
