For many lenders, it's too late in the day for a reprice. Most others still haven't seen enough weakness for a reprice. For the 1-3 lenders not covered by the disclaimers above, Fannie 3.5 MBS are back down to their previous 102-14 lows--this time with 10yr yields breaking to session highs.
Things get less dramatic when we add numbers into the conversation. 10's are up less than 1bp, in light volume.
If you weren't planning on locking today, there's little reason to do so now. If you were planning on locking, or for some strange reason waiting to see if there would be any positive reprices, now's as good a time as any.
