Fannie Mae and Freddie Mac will drop the 25 basis point adverse-market fee that had been applied to all mortgages since 2008 as part of the Federal Housing Finance Agency’s three-pronged adjustment in the guaranty fee the GSEs charge lenders. The FHFA announced changes to GSE g-fees that will amount to an average increase of approximately 11 bps, to be implemented in March and April. Analysts at Barclays Capital said the effective g-fee on 30-year fixed-rate mortgages will be about 62 bps.
