Underwrite to higher-for-longer: yields jump as Iran risk returns

Geopolitics keeps adding upside risk to yields, a reminder to stop penciling 2026 rate cuts into the pro forma.

The yield that prices most real estate debt just climbed to a seven-week high, and the trigger was not the Federal Reserve but the Middle East, a reminder to developers that the case for cheaper capital in 2026 keeps slipping and belongs nowhere in a pro forma.

Why it matters

Every deal underwrites off the 10-year Treasury, and it is moving the wrong way for reasons no rate cut can quickly reverse. When yields jump on an oil spike and renewed war risk rather than on domestic data, it signals that the path to lower borrowing costs is exposed to shocks a developer cannot model or hedge. The practical takeaway is to underwrite to higher-for-longer: assume today’s debt cost holds, stress the exit cap rate upward, and treat any rate relief as upside rather than a base case. Deals that only pencil on a 2026 refinancing at lower rates are the ones most likely to join the distressed pipeline.

The numbers

The benchmark 10-year Treasury yield rose to about 4.59%, a seven-week high, after President Trump signaled the Iran ceasefire had effectively ended and oil prices surged. The 30-year fixed mortgage has hovered near 6.5%, and demand is holding despite the pressure: Mortgage Bankers Association data for the week ending July 3 showed purchase applications down 1% for the week but still up 5% year over year, with refinance activity up 8% from a year earlier even as it slipped week to week. Rates are elevated, in other words, but housing demand has not broken.

What’s next

Watch the 10-year, not the headlines, as the cleaner read on where construction and permanent debt price from here. Persistent geopolitical risk premium argues for building rate-shock cushions into every capital stack. Track the wider capital picture at the national market hub.
