The average 30-year fixed mortgage rate climbed for a third straight week to 6.76%, its highest level in more than 14 months, as the U.S. war with Iran drives oil prices higher and fuels fresh inflation concerns that are punishing borrowers and freezing an already stagnant housing market.
Freddie Mac's weekly survey, released Thursday, showed the benchmark rate ticking up from 6.71% the prior week. The last time the 30-year rate sat this high was June 26, 2025, when it touched 6.77%. A year ago, the same rate stood at 6.35%, meaning a borrower shopping today faces significantly steeper monthly payments than one who locked in last summer.
The 15-year fixed rate followed the same trajectory, rising to 6.09% from 6.04% a week earlier. A year ago, that rate was 5.5%.
Behind the surge sits a bond market rattled by war, debt, and a Federal Reserve that shows no sign of easing up. The 10-year Treasury yield, the benchmark that most directly influences mortgage pricing, hit 4.92% at midday Thursday, up sharply from 4.77% the week before. In late February, before the U.S. war with Iran began, that yield sat at just 3.97%. Treasury yields have now reached levels not seen since late 2023.
Federal Reserve Chairman Kevin Warsh added to borrowers' anxiety late last month at the Fed's annual economic symposium in Jackson Hole, Wyoming. Warsh said inflation had not shown sufficient improvement and that the central bank might have "more work to do", a clear signal he is weighing a rate increase at the Fed's next meeting, scheduled for September 15, 16.
Wall Street is taking the hint. CME Group data showed traders pricing in roughly a 70% probability of a rate hike at that September meeting, up from 61% just the day before. The Fed does not set mortgage rates directly, but its decisions ripple through the bond market and shape the borrowing costs that millions of Americans pay.
The Fed originally raised its key interest rate to combat the super-high inflation that followed the COVID-19 pandemic. That campaign helped cool prices but crushed the housing market. Now, with war-driven oil prices stoking new inflation worries, the central bank appears ready to tighten further, even as homebuyers and homeowners already struggle under the weight of elevated rates.
The U.S. Treasury Department stepped into the bond market last month as long-term yields surged, driven in part by growing concerns about the federal government's ballooning debt. The specific nature of that intervention was not detailed, but the result speaks for itself: yields kept rising anyway.
That combination, a foreign war pushing energy costs higher, a central bank leaning toward tighter policy, and a government whose own borrowing is spooking investors, has created a vise grip on mortgage rates. Each factor alone would pressure borrowing costs upward. Together, they have pushed rates to a level that adds hundreds of dollars per month to a typical home loan payment compared to where rates sat before the conflict began.
The damage to the housing market is visible and measurable. U.S. home sales have been largely stagnant, stuck near a 30-year low. Sales slowed again last month. Prospective buyers are delaying purchases, priced out by rates that have erased much of the purchasing power they had even a year ago.
The slump stretches back to 2022, when mortgage rates began climbing from their pandemic-era lows. What was supposed to be a temporary adjustment has turned into a four-year grind. Home sales flatlined last year at their weakest annual pace in three decades, and 2026 has brought no relief.
Higher rates do not just sideline buyers. They trap existing homeowners in place, unwilling to sell and trade a low-rate mortgage for a new loan near 7%. That dynamic chokes supply, distorts home prices, and leaves the market frozen in a way that hurts nearly everyone except those who locked in cheap financing years ago.
The downstream consequences reach beyond individual borrowers. Rising costs and stalled sales have contributed to mounting foreclosure pressure on homeowners squeezed by rates, taxes, and insurance. And the affordability crisis has left millions of younger adults unable to form independent households at all.
With borrowing costs pushing toward 7% and the Fed openly weighing another hike, the near-term outlook offers little comfort. The 10-year Treasury yield has nearly doubled the gap between its pre-war level and today's mark, and nothing in the current policy landscape suggests that gap will close soon.
When war abroad, debt at home, and a hawkish Fed all pull in the same direction, ordinary Americans trying to buy a house are the ones left holding the bill.
