Modestly stronger overnight with some additional gains after early peace talk headlines. MBS up an eighth and 10yr down 2.2bps at 4.547
MBS now up only 1 tick (.03) and down 7 ticks (.22) from the AM highs. 10yr up 0.4bps at 4.572 after briefly trading below 4.53.
5.0 MBS coupons are down 7 ticks (.22) from 9:30am levels. Lenders who priced before 10am are seeing at least an eighth of a point of that weakness. Negative reprices are relatively rare in these scenarios, but they do happen on occasion.
The losses correspond with push-back on this morning's war-related headlines. In not so many words, the push-back says that diplomatic visits to Tehran are either not real or simply not a sign of an imminent deal.
