"Treasury yields ticked down 3 basis points after weak manufacturing data. In response, the 30-year mortgage rate dropped 2 basis points to 3.93%,” said Sean Becketti, chief economist with Freddie Mac.

“After the survey closed, Yellen implied that the economy is ready for a rate hike in December. However, all eyes remain on this Friday's jobs report, the last significant release prior to the FOMC's meeting,” he added.
