In a way, today was the best sort of losing day for bond markets.  If you factor out last Friday, today was the best trading day for bond markets in more than 8 months, and even then, it wasn't too terribly far off Friday's levels. 

Fannie 3.0 MBS fell a quarter point and 10yr yields rose 2.7bps to 1.95%.  Most lenders did NOT hit rate sheets for a full quarter point in price, but that depends on their approach to pricing on Friday as well as the time of morning that they got sheets out today. 

All that said, I'd suspect there's a bit more latent weakness that has yet to make its way onto rate sheets if MBS were to hold perfectly steady right here.  Reason being, most lenders priced into falling prices this morning and never saw enough weakness to reprice, despite MBS falling another 2-4 ticks from rate sheet print times.
