WASHINGTON — The average interest rate on the most popular U.S. home loan jumped to its highest level in nearly three years last week, adding fresh pressure on prospective buyers already struggling with expensive homes and a sharp rise in borrowing costs.
The average rate on a 30-year fixed-rate mortgage climbed 19 basis points to 7.49% in the week ended October 2, according to data released Wednesday by the Mortgage Bankers Association. The rate was last higher in November 2023 and has risen rapidly as a selloff in U.S. government bonds pushes longer-term borrowing costs upward.
Mortgage rates have increased by about 1.4 percentage points since late February, broadly tracking a sharp rise in the benchmark 10-year U.S. Treasury yield. The 10-year yield climbed above 5.3% earlier this week, reaching its highest level in about 24 years as investors responded to persistent inflation concerns, higher energy prices and stronger-than-expected economic growth.
The jump in borrowing costs is increasingly weighing on mortgage demand. Total mortgage applications fell 4.2% from the previous week, extending a decline that has pushed overall application volumes to their lowest level since February 2025. Application activity is now nearly 50% below January levels.
Refinancing has been particularly vulnerable because millions of American homeowners already hold mortgages carrying substantially lower rates. With new borrowing approaching 7.5%, relatively few homeowners have a financial incentive to replace existing mortgages, while prospective buyers are also stepping away from the market as monthly payments become increasingly difficult to absorb.
Higher mortgage rates can significantly alter the amount a household can afford even when the price of the property remains unchanged. On a $400,000, 30-year mortgage, for example, principal and interest at 7.49% would amount to roughly $2,793 a month, compared with about $2,398 at 6%. That represents a difference of almost $400 every month, before property taxes, homeowners insurance and other housing expenses are included.
The renewed pressure on housing comes as inflation remains above the Federal Reserve's target. The inflation measure closely watched by the central bank was running at 3.4% in August, compared with the Fed's 2% goal, complicating expectations for how quickly policymakers will be able to bring borrowing costs down.
The Federal Reserve raised its benchmark interest rate in September for the first time since 2023 as officials sought to prevent inflation from becoming entrenched again. Policymakers have indicated another increase could be appropriate before the end of the year, although financial markets currently see a substantially smaller chance of another move at the Fed's meeting later this month.
Oil prices have added another layer of uncertainty. Brent crude moved back above $100 a barrel on Wednesday as Middle East supply concerns persisted, increasing fears that higher energy costs could feed through to transportation, manufacturing and consumer prices and make the inflation outlook more difficult for the Fed.
Pressure is also intensifying across the Treasury market. The yield on the 30-year U.S. government bond briefly reached about 5.70% on Wednesday, another 24-year high, as investors demanded greater compensation for holding long-term government debt amid concerns over inflation and federal borrowing.
Those market movements matter directly to housing because mortgage rates tend to move closely with longer-term Treasury yields rather than simply following the Federal Reserve's overnight policy rate. When investors demand higher returns on government bonds, mortgage-backed securities generally must offer more attractive yields as well, eventually raising the interest rates lenders charge homebuyers.
The result is a difficult combination for the U.S. housing market. Potential buyers face mortgage rates above 7%, while many existing homeowners remain reluctant to sell because doing so could mean giving up mortgages obtained several years ago at dramatically lower rates and replacing them with much more expensive financing.
That so-called mortgage lock-in effect can restrict the number of existing homes coming onto the market even as high interest rates weaken buyer demand. It helps explain why elevated mortgage rates do not necessarily translate quickly into sufficiently lower home prices to restore affordability.
Homebuilders face a similar challenge. Higher financing costs have weakened demand for new single-family homes and contributed to an accumulation of unsold properties in parts of the country, forcing some builders to rely more heavily on incentives, including mortgage-rate buydowns, to attract buyers.
The housing slowdown is becoming increasingly important for the broader U.S. economy because residential real estate affects construction, banking, consumer spending and household wealth. A prolonged period of mortgage rates near current levels could further suppress transactions and construction activity even if the wider economy remains relatively resilient.
For borrowers, the direction of the Treasury market may now be as important as the next Federal Reserve decision. A sustained decline in longer-term yields could eventually pull mortgage rates lower and release some pent-up housing demand, while another surge in inflation or oil prices could keep financing costs elevated.
For now, the latest data show little relief. A 7.49% mortgage rate, falling application volumes and Treasury yields near multi-decade highs are reinforcing an affordability squeeze that has made financing a home substantially more expensive than it was only several months ago.
The central question for the housing market is therefore shifting from whether mortgage rates will return above 7% to how long they remain there. The answer could determine whether buyers continue postponing purchases, sellers remain locked into older mortgages and the U.S. housing market enters an even longer period of subdued activity.
