Many lenders aren't even out with rate sheets yet, so naturally, this alert won't apply to them.  Other lenders put out rates right as MBS were making their highs of the morning--or close to it.  Lenders in that category could already be considering negative reprices as Fannie 3.0s and 3.5s are both down at least 5/32nds since then.

10yr yields are also up to their session highs as a fairly large wave of corporate debt issuance is hitting the newswires.  (More on how corporate issuance affects rates HERE).
