MBS & US Treasury Markets
6/4 3:31:58AM EST : Delayed Data

MBS are now down 3 ticks (.09) on the day.  These are the lowest levels and more than an eighth of a point below most lenders' rate sheet print times.  As such, negative reprices are increasingly possible. 

10yr yields are up 2.4bps at 4.47 -- the highs of the day, but just barely.
