The average U.S. 30-year fixed mortgage rate climbed to 7.40% this week, reaching its highest level since November 2023 as rising Treasury yields feed directly into household borrowing costs.
Freddie Mac said Thursday that the benchmark rate increased from 7.28% the previous week.
The increase reflects the broader repricing in long-term U.S. interest rates as investors contend with higher energy prices, persistent inflation and uncertainty over the Federal Reserve’s next moves.
The housing consequences operate in both directions.
Higher rates make monthly payments more expensive for prospective buyers, reducing affordability and suppressing demand.
At the same time, homeowners who already hold mortgages below 5% have a strong financial incentive not to sell and replace those loans with financing above 7%.
That lock-in effect restricts the supply of homes available for sale, particularly in the starter-home segment.
The result is a housing market where weaker demand does not necessarily translate into sharply lower prices because supply remains constrained.
The increase also illustrates how movements in Treasury markets reach the real economy.
Mortgage rates generally track longer-term government yields rather than the Federal Reserve’s overnight policy rate directly. That means households can face tighter financial conditions even when the Fed itself does not raise rates at a particular meeting.
For buyers, the next major variable is therefore not simply the October Fed decision but whether long-term Treasury yields stabilize.
If they remain near multi-decade highs, housing affordability is likely to remain under pressure even without another immediate increase in the federal-funds rate.
