The ten-year Treasury broke down to 4.61% this morning, a nine basis point improvement from where we sat Tuesday and the best level since the Strait of Hormuz closed. The 30-year fixed followed it lower to 6.60%, down four basis points. But the rest of the sheet did not cooperate: the 15-year rose two basis points to 6.09% and the 5/1 ARM added six to 6.79%, which now prices a full 19 basis points above the 30-year fixed. That inversion widened again for the third consecutive session and it is the single most important pricing fact on your desk this morning. Every ARM quote you gave a client before Friday is stale, and the product you would have reached for six weeks ago to buy a borrower into a lower payment is now the most expensive fixed-period option you can offer.
The move in the long end is entirely a geopolitical trade. Treasury Secretary Scott Bessent told CNBC Tuesday that an agreement allowing commercial shipping back through the Strait of Hormuz could be finalized this week, and U.S. Central Command declared the southern route free and open. Crude tumbled almost 6% in Tuesday's session and yields fell hard alongside it. The 30-year bond is back to 5.16% and the two-year sits at 4.21%, which leaves the curve steeper and tells you the market is pricing an inflation relief story, not a growth scare. That distinction matters. The Fed held at 3.50% to 3.75% on July 29 on a 9-to-3 vote where all three dissenters wanted a hike, and those dissents were about energy pass-through into core services. If the Hormuz deal actually lands, the hawkish bloc loses its best argument and the September 15-16 meeting reopens.
Practically, this is a two-track morning. On agency purchase business, the 30-year at 6.60% is roughly 24 basis points better than the June high and worth about $95 a month on a $500,000 loan, which is enough to move a pre-approval up a tier for buyers who were sitting right at the DTI line. On refi, do not get excited yet. MBA data showed applications down 6.4% for the week ending July 24 with refis alone off 10%, and the pool of borrowers above 7% is still thin. The better use of a rally like this is repricing your live pipeline before it fades. Geopolitical rate improvements have a short half life, and this one is riding on a deal that has not been signed.
