The monthly rollover took place overnight for FNMA and FHLMC 30-yr securities. The current coupon switched from the March to the April contract. If you are tracking daily MBS price movements, April MBS prices reflected a drop of about -7/32 from March. This change is priced in over the course of the month, so the impact on mortgage rates on the day of the rollover is generally no greater than on any other day of the month.
