Most lenders are not yet out with rate sheets, but for those with the ability to lock yesterday's rates, this is a heads-up that MBS just moved into negative territory (down about 5 ticks or 0.16 from this morning's first liquid highs). 10yr yields are now up 1.6bps at 4.34 after being as low as 4.30+ a few hours ago.
The move apparently follows this newswire:
NO IRAN-U.S. TALKS TO TAKE PLACE DURING FM ABBAS ARAGHCHI’S VISIT TO PAKISTAN, ONLY BILATERAL ENGAGEMENT
A short while before that, Araghchi's diplomacy tour was seen as a potential indication of negotiations.
