The third quarter is about to end and most GSE watchers can agree on one thing: Fannie Mae and Freddie Mac should turn in stellar earnings for the period. According to preliminary estimates from Inside The GSEs, all lenders could wind up funding $570 billion in 3Q, compared to $510 billion and $380 billion in 2Q and 1Q, respectively. The higher production figures should translate into a jump in guaranty fee income, which will feed the coffers of the GSEs. The “wild card” in their performance will be the yield on the 10-year Treasury, which was slated to close 3Q16 at 1.57 percent, 9 basis points higher than June 30.
