It's easy to lose sight of the current sell-off in this morning's shuffle. There's been a lot of back and forth. Unfortunately, the highs of the day coincide with lender rate sheet print times and MBS have lost just over a quarter of a point since then. Lenders who priced near those highs could be considering negative reprices.
MBS are down 3 ticks (.09) on the day and 10yr yields are up 1.6bps at 4.271.
