US 30-year mortgage rates rise to 7.28%, reaching highest level since November 2023

Benchmark rates reach three-year highs

The average rate on a 30-year fixed-rate mortgage in the United States rose to 7.28% in the week ending October 1, 2026, up from 7.03% the prior week, according to Freddie Mac. The 0.25 percentage point increase was the largest weekly jump since October 2022 and marked the sixth consecutive week of increases. The rate reached its highest level since November 22, 2023, when it stood at 7.29%, compared to 6.34% twelve months ago. The 30-year average had previously dropped to 5.98% in late February 2026, its lowest point since late 2022. Borrowing costs on 15-year fixed loans also climbed, averaging 6.60% compared with 6.42% the previous week and 5.55% a year earlier.

Treasury yields and inflation pressures

The upward movement in mortgage costs accompanied an intensifying sell-off across the US government bond market. Lenders price long-term fixed loans against the 10-year US Treasury yield, which reached 5.27% during midday trading on Thursday, matching levels from 2007. The yield stood at 3.97% in late February 2026, prior to military strikes launched by the United States and Israel against Iran on February 28. US Treasuries recorded their worst monthly performance in four years during September 2026. Bond investors have factored in the possibility of prolonged Federal Reserve interest rate pressure as Middle East commodity disruptions and expanding spending on artificial intelligence sustain inflation ahead of US midterm elections.

Financial pressure on buyers and builders

Higher borrowing costs have compounded affordability challenges in a market already constrained by elevated property prices, according to the Case-Shiller home price index. The rate increase of more than one percentage point since late February adds approximately $276 each month to payments on a $400,000 home loan. Construction companies have experienced weakening demand and high building costs since June 2026. In third-quarter financial results, listed builder KB Home reported a 20% year-on-year drop in revenue and a 19% decrease in homes delivered, while Lennar Corporation, the second-largest US builder by volume, also logged lower revenue.

KB Home executive chair Jeffrey Mezger described the effect on buyer activity:

Higher mortgage interest rates have further pressured affordability and, together with geopolitical uncertainty and broader economic headwinds, have caused many prospective buyers to be more cautious on purchasing a home.

Growth in adjustable-rate financing

To lower initial monthly outlays, more buyers have sought adjustable-rate mortgages (ARMs). Data from the Mortgage Bankers Association showed ARM applications rising to 10.3% of total loan requests, reaching their highest share in one year. ARMs generally offer introductory interest rates up to one full percentage point below standard fixed-rate loans for an initial term of five, seven, or ten years. Once that period concludes, loan payments reset on an annual basis to reflect prevailing market benchmarks.

Mortgage Bankers Association deputy chief economist Joel Kan explained the shifting borrower strategy:

They are looking for more ways to get into that home.

Borrowers utilizing ARMs take on the financial risk that borrowing costs could remain elevated or climb further by the time their initial fixed window closes.
