MBS are now down just over 5/8ths of a point on the day. 5 ticks (.16) of that has been seen since 9:30am, which is an early part of the window for lender rate sheet print times.
Most every lender has baked in plenty of weakness to this morning's rate sheets, so the bar for negative reprices is probably a bit higher than normal (i.e. negative reprices aren't necessarily highly likely at the moment, but we're heading in that direction).
