Bonds hit their highs just after 10am this morning and have been selling slowly since then. The last few minutes bring 5.0 UMBS down 5 ticks (.16) versus those highs. The catch is that "just after 10am" is on the later side of the normal morning price window for lenders.
Bottom line: lenders who printed their first rate sheet well after 10am could technically justify a small reprice. Lenders who priced at 10am (or earlier) still haven't seen meaningful deterioration from their rate sheet print times.
