MBS have fallen fairly gently to the lows of the day with 5.5 coupons now down 6 ticks (.19).  That said, lenders are seeing a maximum of an eighth of a point of weakness from intraday highs, which is usually not quite enough for the average lender to consider a negative reprice.  

Only the jumpiest lenders would be considering it at this point.

10yr yields are not yet at their highs of the day, currently up 4.8bps at 4.231.  

The weakness follows Fed Chair Powell's interview at the Economic Club of Washington, specifically after a comment about avoiding sending any signals on any particular meeting's rate cut odds.
