MBS & US Treasury Markets
12/27 5:59:00PM EST : Delayed Data

MBS are now down 2 ticks (.06) on the day and just barely an eighth of a point from the AM highs.  Some later-pricing lenders released rates during those highs, so if they're feeling jumpy, they could technically justify a negative reprice.

That's not especially likely, but possible.  With that in mind, if you weren't planning on locking today, there's no burning reason to do so.  And if you were planning on locking, there's no reason to wait.
