SKN | U.S. Mortgage Rates Hit 13-Month High as Higher Borrowing Costs Squeeze Homebuyer Purchasing Power

The average 30-year fixed mortgage rate rose to 6.71%, its highest level since July 2025, increasing the cost of financing for homebuyers. The 15-year mortgage rate also climbed to 6.04%, further raising borrowing costs for buyers and homeowners considering refinancing. Higher rates are reducing purchasing power and encouraging some prospective buyers to delay transactions, adding to already sluggish U.S. home sales.

U.S. mortgage rates are moving higher again, putting additional pressure on a housing market already struggling with weak transaction activity. The increase is significant because borrowing costs directly affect how much buyers can finance and how much of their income must be allocated to housing.

The Public Assumption

The common assumption is that a mortgage rate around 6% to 7% is simply a temporary obstacle that buyers can overcome by adjusting their budgets. But even relatively small changes in rates can materially alter monthly payments, particularly for households financing large balances.

According to Freddie Mac, the average 30-year fixed mortgage rate increased to 6.71% from 6.66% the previous week. The rate was 6.50% a year earlier and has now reached its highest point since July 31, 2025, when the average was 6.72%.

The increase also affects existing homeowners considering refinancing. The average 15-year fixed rate rose to 6.04% from 5.98%, compared with 5.60% one year ago.

The Economic Breakdown

Mortgage affordability is determined by more than the listed price of a home. The financing rate determines how much of that price a household can realistically support through monthly payments.

When rates rise, buyers who maintain the same monthly housing budget generally have to reduce the amount they are willing or able to borrow. Alternatively, they must increase their down payment, accept a higher monthly payment or search for less expensive properties.

That creates a direct connection between interest rates and transaction volume. If prospective buyers believe financing costs are unfavorable, some may delay purchasing rather than accept reduced purchasing power. The result can be fewer completed sales even when homes remain available on the market.

The Hidden Picture

The mortgage rate itself is only one component of the cost of owning a home. Buyers must also account for property taxes, insurance, maintenance and, where applicable, homeowners association fees. Higher financing costs can therefore compound other ownership expenses rather than operate independently.

Mortgage rates are also not determined solely by the Federal Reserve’s policy rate. Inflation, expectations for monetary policy and bond-market views of the economy all influence borrowing costs. The 10-year Treasury yield is particularly important because mortgage rates generally move in relation to it and is used by lenders as a pricing reference.

This means that even if expectations for future Federal Reserve policy change, mortgage rates can remain elevated if bond investors continue demanding higher yields.

Closing

With the 30-year mortgage rate back above 6.7%, the critical housing question is no longer simply whether buyers want homes, but how much purchasing power remains after the cost of financing is calculated.
