MBS are now unchanged on the day, down nearly a quarter point from opening levels and just over an eighth of a point from some lenders' rate sheet print times.  As such, those lenders could be considering negative reprices.  That said, most lenders are looking at the next delivery month for MBS where there's only a 3 tick gap (0.09) versus rate sheet print times.  

10yr yields are still down 2.2bps on the day, but also near their highs, currently at 4.462.
