MBS are still up 2 ticks on the day, but down exactly an eighth of a point from pre-Fed highs (but only half of that weakness has happened since the Fed announcement).
10yr yields are up 0.6bps at 4.391--the highs of the day.
The jumpiest of the jumpy lenders could be seeing the bleeding edge of negative reprice risk here, but it's not yet fully justified by price movement.
