US Mortgage Rates Hit Highest Level in Nearly Three Years

US mortgage rates jumped last week to their highest level in nearly three years, adding pressure on buyers and homeowners just weeks before the midterm elections. The Mortgage Bankers Association said the average 30-year fixed-rate mortgage rose 19 basis points to 7.49 percent in the week ended October 2, the highest since November 2023, according to Reuters reporting published October 7.

The increase marks another step in a rapid climb for borrowing costs. Reuters reported that home borrowing rates are up about 1.4 percentage points since joint US and Israeli strikes against Iran began in late February, tracking a similar rise in Treasury yields as oil prices and inflation concerns have pushed bond markets higher.

US mortgage rates follow Treasury yields higher

Mortgage pricing in the United States is closely tied to the yield on the 10-year Treasury note, which lenders and investors use as a benchmark for long-term loans. Reuters reported that the 10-year yield topped 5.3 percent this week and earlier hit a 24-year high, driven by worries about inflation from soaring oil prices and by data showing stronger US economic growth.

When Treasury yields rise, mortgage rates usually follow, though the gap between the two can widen or narrow depending on investor demand for mortgage-backed securities. For borrowers, the practical effect is immediate: a higher rate raises the monthly payment on the same loan amount and can reduce the price range a buyer can afford.

• Average 30-year fixed rate: 7.49 percent, up 19 basis points in one week
• Last time higher: November 2023, according to the Mortgage Bankers Association
• Mortgage applications: down 4.2 percent from the prior week
• Overall application volume: lowest since February 2025, down nearly 50 percent since January

Applications fall as buyers step back

The higher rates are cooling demand. The Mortgage Bankers Association said mortgage loan applications fell 4.2 percent last week, with refinancing applications dropping sharply, according to Reuters. Overall volumes are the lowest since February 2025 and have fallen nearly 50 percent since January, the association reported.

HousingWire’s coverage of the prior week’s survey found a similar pattern, with total applications down 6 percent in the week ended September 25 and both purchase and refinance indexes declining. Joel Kan, the MBA’s vice president and deputy chief economist, said in that survey summary that rising rates pushed borrowers to the sidelines and left application activity at its slowest weekly pace since 2025.

Refinancing is especially sensitive to rate moves. Homeowners who locked in much lower rates earlier in the decade have little financial reason to refinance into loans above 7 percent, while buyers facing both high prices and high rates often delay purchases or look for smaller homes.

Adjustable-rate loans gain share

One sign of borrowers hunting for relief is the growing share of adjustable-rate mortgages. HousingWire reported that ARMs accounted for 10.3 percent of application activity in late September, the highest share since October 2025, with ARM rates roughly 80 basis points below comparable fixed rates. That trade-off can lower an initial payment, but it also exposes borrowers to the risk that payments rise later if rates stay high.

The Federal Reserve and inflation backdrop

The mortgage market is also being shaped by expectations for Federal Reserve policy. Reuters reported that inflation registered 3.4 percent in August on the measure the Fed targets at 2 percent, and that Fed policymakers have signaled they expect to follow September’s interest-rate increase with another hike by year-end. Markets, however, are currently betting the central bank will not move at its late-October meeting, according to the same reporting.

On Thursday, Federal Reserve Governor Christopher Waller hinted at a possible pause at the upcoming meeting while saying more hikes may still be needed to bring inflation back to target, according to market coverage by Investopedia and the Economic Times. For mortgage borrowers, even a pause may not bring quick relief if Treasury yields remain elevated on oil and inflation worries.

Why it matters beyond housing

Housing costs are a central part of the cost-of-living debate heading into the November 3 elections. Reuters cited a Reuters/Ipsos poll completed this week in which the cost of living ranked as the top issue on Americans’ minds. Mortgage rates are one of the most visible ways that tighter financial conditions reach household budgets, affecting buyers, sellers, builders and local economies tied to home sales.

For now, the direction depends on forces outside the housing market itself: oil prices, inflation data, Treasury yields and the Fed’s next decisions. Radiosea will track the Mortgage Bankers Association’s weekly survey for signs of whether demand stabilizes or borrowing costs climb further.
