Mortgages are experiencing some localized weakness thanks to a modest pick up in originator selling (5.0s) and servicer duration dumping. 

The FNCL 4.5 is -0-17 at 101-26. The secondary market current coupon is +10.6bps at 4.163%. Yield spreads are at their widest levels of the day by my static scorecard and lenders are preparing for REPRICES FOR THE WORSE.
