US Housing & Mortgage Markets

The bond market sold off hard last Friday on no progress in the Iran conflict, pushing the 10-year yield to 4.596% and mortgage rates to 2026 highs — and the question now isn't whether rates are elevated, but how long buyers will hold on before demand breaks.

RATES AT THE EDGE OF THE DANGER ZONE

Mohtashami's 2026 forecast penciled in a mortgage rate ceiling of 6.75% and a 10-year ceiling of 4.60% — and last week's close landed almost exactly on both limits simultaneously. What's kept rates from breaching 6.75% outright: better-than-expected mortgage spreads absorbing some of the Treasury pressure. That's the silver lining, and it may not last.

The threshold to watch is 6.64%. Mohtashami's historical read is clear: once rates clear that level and push toward 7%, housing demand has reliably softened over the past several years. We're not there yet, but we're close enough that the spread compression doing the work right now matters enormously.

The macro driver is geopolitical, not Fed-driven. The Iran conflict has closed the Strait of Hormuz long enough to start thinning petroleum product inventories — motor oil, jet fuel, naphtha — and bond markets are pricing the prolonged disruption. Mohtashami flags June through September as the critical window: oil reserves are dwindling, and if no deal materializes by early June, the pressure on yields intensifies. The bond market has already begun pricing a rate hike in 2027, a remarkable shift in expectations.

DEMAND: RESILIENT, BUT ON WATCH

Despite the rate spike, the near-term demand picture hasn't cracked. Weekly pending home sales remain positive year-over-year, and mortgage purchase applications were up both week-over-week and year-over-year for the latest reading. Buyers haven't flinched — yet.

The operative word is "for now." Mohtashami's framing is explicit: this positive trend holds only as long as rates stay below the historical demand-destruction threshold. The data is still green, but it's green with a flashing caution light.

POLICY SIDEBAR: SUPPLY-SIDE LESSONS FROM TOKYO

Potter's reading list (filed between bouts of illness) surfaces a useful supply-side data point from analyst Alex Armlovich: Tokyo's relative housing affordability isn't a story of cheap land — a one-acre central Tokyo lot would cost over $100 million — it's a story of cheap structures enabled by permissive zoning. The takeaway Armlovich draws: cities can build toward affordability without destroying land values. Potter also flags movement on a Senate housing bill, with the House now formulating a response, though details remain thin. His forthcoming piece on the build-to-rent industry may offer more direct US market signal next week.

CLOSING SYNTHESIS

This week's signal is fundamentally about geopolitical risk bleeding into rate risk bleeding into demand risk — a chain reaction that hasn't fully played out yet. The Iran conflict is now the single most important variable for US mortgage rates, overriding any Fed policy signal in the near term. Demand is holding, purchase applications are positive, and spreads are helping — but the runway between "elevated" and "demand-killing" has narrowed to a very thin margin. Mohtashami's June watch period is the next real test.

TL;DR - Rates at yearly highs: The 10-year yield closed at 4.596% — the top of Mohtashami's 2026 forecast — with mortgage rates approaching but not yet breaching the 6.75% ceiling, held back by favorable spreads. - Demand still positive, but near a threshold: Purchase applications and pending sales are up YoY, though Mohtashami's data shows demand historically softens once rates clear 6.64%–7%. - Iran is the macro wildcard: The conflict is driving bond-market stress; Mohtashami flags June–September as the high-risk window if oil reserves continue falling without a deal. - Supply-side policy in motion: A Senate housing bill is advancing to the House, and Tokyo's build-more model offers a reminder that abundant supply can coexist with high land values.
