Rates and bond yields have been climbing steadily in recent weeks – and with the Iran war showing no sign of ending, they could be about to jump even higher
The question hanging over the United States mortgage market this week is stark: with bond yields surging and war roiling oil markets, are 30‑year fixed rates about to test 7% again?
In recent weeks, benchmark mortgage rates have climbed back into the mid‑6% range.
The Mortgage Bankers Association reported the average contract rate for 30‑year fixed mortgages at about 6.43% last week, up from 6.30% and the highest since October 2025, as application volumes dropped by 10.5%.
“The threat of higher‑for‑longer oil prices continued to keep Treasury yields elevated, and mortgage rates finished last week higher,” said Joel Kan, MBA’s vice president and deputy chief economist.
Freddie Mac’s latest survey put the average 30‑year fixed at 6.38%, up from 6.22% a week earlier and just under 6% at the start of the month.

Bond market braces for prolonged conflict
The 10‑year Treasury yield, the key reference for mortgage pricing, moved from just below 4% on the eve of the Iran war to nearly 4.4% this week.
In one recent bout of volatility, it jumped nine basis points in a single session to about 4.05%.
“As far as its impact on the market, what people don’t realize is war is inflationary,” broker Shadi Nurani told Mortgage Professional America.
“You have spikes in oil prices… the likelihood of the Fed needing to print money goes through the roof.”
Federal Reserve officials, facing another energy‑driven inflation shock, sounded more hawkish.
“I could see circumstances where we would need to raise rates if it was going a different way, and inflation was getting out of control,” said Chicago Fed president Austan Goolsbee.
The Organization for Economic Cooperation and Development raised its 2026 US inflation forecast to around 4.2%, well above both its prior projection and the Fed’s 2.7% estimate, fanning talk of a possible stagflationary mix of weaker growth and sticky prices.
Markets weigh 7% risk against buyer fatigue
Against that backdrop, traders were pricing in a meaningful chance that longer‑term yields could push higher if diplomacy faltered.
President Donald Trump repeatedly said talks with Iran on ending the war were going “very well,” even as Iranian officials publicly denied negotiations were taking place and vowed to continue fighting. That disconnect left markets bracing for more headline‑driven swings.
For originators and brokers, the key question is not whether rates might briefly print a 7‑handle, but how borrowers would react if they did.
When mortgage rates previously approached that threshold, “seeing a mortgage rate close to the 7% mark might be initially dispiriting,” loan officer Jay Lessard told MPA, but buyers who could handle the payment often decided “it may be in their interest to move ahead” rather than wait.
What higher‑for‑longer could mean for housing
Freddie Mac’s chief economist Sam Khater warned earlier that even modest shifts in yields could quickly feed through to housing costs. The 30‑year mortgage rates were already averaging about 6.22% before the latest spike, with the odds of any Fed rate cuts this year fading as gas prices surged.
For now, industry veterans viewed 7% not as a certainty, but as a live risk.
If the 10‑year Treasury pushed decisively above recent highs and energy prices stayed elevated, the spread that lenders demanded could bring headline rates back to levels last seen in 2023.
If diplomacy gained traction or inflation data surprised lower, that pressure could ease.
