Iran-U.S. ceasefire sparked a bond rally — 30yr closed at 6.60%, down 7 bps on the day.

The afternoon changed everything. Iran and the United States reached a ceasefire agreement — Trump cancelled planned air strikes at roughly 1:30 PM Eastern and announced that both sides had approved final deal details, with a signing time and location to be announced. Markets reacted immediately: stocks surged, oil dropped, and bond yields fell sharply.

By the close, UMBS 5.0 had rallied to 98.19 — up 65 basis points from Wednesday's close. The 10-year Treasury finished at 4.457%, down nearly 10 basis points on the day. Almost every lender made a mid-day positive reprice. The 30-year conventional rate closed at 6.60%, down 7 basis points from this morning's open and at its best level since last Thursday.

What it means for borrowers: today's move is significant enough to matter. If you were quoted a rate this morning and haven't locked, call your lender — afternoon reprices were broadly favorable. The ceasefire news introduces a new variable: if the deal holds and oil prices stay lower, energy-driven inflation pressure eases, which is structurally positive for rates. If the deal unravels, bonds give back today's gains quickly. The rate environment remains volatile and geopolitically driven. Lock with intent, not with hope.
