On Friday, the 10-year yield closed at 4.596%, the high end of HousingWire's 2026 forecast range. Mortgage rates followed, hitting yearly highs after a bond market rout tied to the escalating Iran conflict. Yet the weekly pending home sales data printed 78,006—up from 73,523 a year ago. Purchase applications rose 7% year-over-year and 4% week-over-week.
The numbers defy the conventional playbook. Historically, mortgage rates above 6.64% and especially above 7% have crushed demand. The current average rate sits at 6.65%, just above that threshold. But the data shows buyers are still showing up, at least for now.
The explanation lies in mortgage spreads. At 1.92%, spreads remain well inside the worst levels of 2023, when they hit 2.50% or higher. If spreads had matched 2023's worst, mortgage rates would be 7.84% today, not 6.65%. The spread compression has effectively shielded the market from the full impact of the 10-year yield surge.
That cushion is fragile. Spreads have already tightened from 1.96% the prior week, but they remain above the historical range of 1.60% to 1.80%. Any widening from here would push rates above 7%, a level that has historically triggered demand destruction.
The Iran conflict is the wildcard. HousingWire's forecast assumed the 10-year yield would stay between 3.80% and 4.60%. It is now at the ceiling. The market is pricing a rate hike in 2027, a dramatic shift from the rate-cut expectations that dominated early 2026.
Oil reserves are the ticking clock. By the second week of June, U.S. strategic reserves will be in a bad place if no deal is reached. That timeline coincides with the seasonal peak in pending sales, making year-over-year comparisons critical. Easy comps have flattered recent data, but that tailwind fades as summer progresses.
Purchase applications are a forward-looking indicator, leading closings by 30 to 90 days. The 7% year-over-year gain is encouraging, but the survey was taken when rates were lower. The real test comes in the next two to four weeks, as the rate spike works through the pipeline.
HousingWire's data shows that mortgage rates under 6.25% have been the sweet spot for sustained demand. The current rate of 6.65% is 40 basis points above that threshold. The market is operating on borrowed time—and borrowed spread compression.
The broader implication is clear: the housing market is in a fragile equilibrium, propped up by favorable spreads and easy year-over-year comparisons. Both supports are eroding. If the Iran conflict pushes the 10-year yield above 4.60% and spreads widen, mortgage rates will breach 7%. At that level, demand has historically collapsed.
The summer months will be decisive. The data from June through September will reveal whether the current demand is a genuine shift in buyer behavior or a temporary artifact of low rates and easy comps. Lenders and investors should watch the weekly pending sales and purchase application data with a forensic eye.
The 10-year yield closed at 4.596% on Friday. That is the high end of the forecast. The next move depends on Tehran, not the Fed. And the housing market is betting that spreads hold.
