Bonds have been selling fairly steadily since 10am with 10yr yields now down less than half a bp at 4.176 and MBS up only 1 tick (.03) on the day. 5.0 MBS coupons are down an eighth of a point from the AM highs seen just after 10am. Lenders who published rate sheets around the time could technically justify a negative reprice, but risks would be higher if MBS turn negative on the day.
