US Mortgage Rate Tops 7% as Treasury Yields Climb

Key Facts

The average US 30-year fixed mortgage rate rose to 7.03% on September 24, 2026, from 6.95% a week earlier, Freddie Mac reported. That puts the benchmark above 7% as homebuyers face a higher cost of financing a purchase. Its last weekly reading above that threshold was 7.04% on January 16, 2025. For a borrower locking a rate now, the same loan principal would require a larger monthly payment if the loan term and other terms were unchanged. The move therefore bears directly on a household’s purchase budget, because the interest cost is built into each payment over the life of a fixed-rate loan.

The increase extended to 15-year fixed mortgages, whose average rate reached 6.42% from 6.26% the previous week, according to Freddie Mac. A year earlier, the 30-year average was 6.30% and the 15-year average was 5.49%. Freddie Mac compiles its weekly averages from mortgage applications submitted through lenders across the country, making the figures a measure of prevailing borrowing costs rather than a quote available to every buyer. An individual offer also reflects the borrower’s credit profile, down payment and loan terms. The annual comparison shows that financing pressure extends beyond one week’s increase, even though offers can differ among lenders.

In the bond market, the US 10-year Treasury yield rose from 4.94% on September 17 to 5.11% on September 23, Treasury data show. That is a gain of 17 basis points over the period. Investors use longer-term Treasury yields as a reference when pricing mortgage-backed securities, which in turn influence lenders’ funding costs. When investors demand a higher return on those securities, it becomes harder for lenders to offer new mortgages at lower rates. The relationship is not a fixed conversion: the extra yield investors require for mortgage risk and liquidity can also widen or narrow.

Energy adds another channel through its potential effect on inflation expectations. The US Energy Information Administration put the global average oil price at $91 a barrel in August 2026, up $7 from July. The agency linked elevated prices to falling global inventories and continuing constraints on oil exports from the Middle East. Sustained energy costs can feed into transport and production costs, shaping the inflation outlook that bond investors incorporate into yields. The path from oil to a home-loan quote therefore runs through expectations, bond prices and lender funding, rather than through a fixed surcharge tied directly to each barrel.

Monetary policy enters the pricing chain by a different route. On September 16, 2026, the Federal Reserve raised its target interest-rate range by 25 basis points to 3.75%–4% and said inflation remained elevated relative to its 2% goal. Its decisions, and investors’ expectations of later decisions, affect yields on longer-dated bonds. A 30-year fixed mortgage does not automatically move by the same amount as the federal funds rate. The bond market’s response to the outlook for inflation and growth is therefore more useful for understanding the rate a prospective borrower is offered.

The financing increase arrives in a housing market that had already lost some momentum. Existing-home sales fell 2% in August from the previous month to a seasonally adjusted annual rate of 3.98 million, the National Association of Realtors reported. The median sale price was $429,100, up 1.6% from a year earlier. The home price helps determine how much a buyer needs to borrow, while the interest rate determines the cost of carrying that debt. When both rise, a buyer may need to target a cheaper property, make a larger down payment or accept a higher monthly bill, depending on income and savings.

Signed contracts and inventory provide a more detailed view than August closings alone. Pending home sales rose 0.3% from the previous month but remained 4.7% below their year-earlier level, according to the same trade group. The stock of existing homes for sale stood at 1.62 million, equivalent to 4.9 months of supply at the reported sales pace. Greater supply can give buyers more room to negotiate a purchase price, but it does not automatically lower the cost of financing the transaction. Pending contracts generally precede completed sales, so any sustained rate change would take time to appear in closing figures.

For a buyer considering when to lock a loan, the 7.03% average signals a higher borrowing cost than a week earlier, while the relevant decision still turns on the actual quote, loan size and down payment. For an owner considering refinancing, the gap between an existing loan rate and a new offer after fees matters more than a round-number threshold in the national average. Housing participants will watch whether Treasury yields stabilize or keep rising, because persistently higher yields could continue to pressure lender offers. Freddie Mac publishes its average weekly, providing a near-term check on the borrowing-cost trend. The Energy Information Administration’s next update, scheduled for October 6, 2026, will also refresh the oil outlook that feeds into inflation expectations.
