MBS & US Treasury Markets
9/22 2:19:55PM EST : Delayed Data

MBS are now down an eighth of a point from AM highs (but just barely weaker on the day). Jumpier lenders could already be considering negative reprices. Upward pressure in oil prices only explains some of the weakness (oil is still lower day-over-day). 

02:09 PM

MBS back into positive territory after earlier losses on reports of Trump meeting with Iranian delegation. Oil and yields dropped together. 10yr now unchanged at 4.953 and MBS up 2 ticks (.06).
