The average 30-year fixed mortgage rate rose to its highest level in more than a year for the week ending Sept. 2, reaching 6.71 percent according to Freddie Mac, the highest since the week ending July 30, 2025.
The rate had dipped below 6 percent in late February before rising as the U.S.-Iran conflict escalated. Rates tend to track the yield on 10-year Treasury bonds, which rises when investors demand more return on safe assets during uncertain periods.
Sam Khater, Freddie Mac’s chief economist, said in a Sept. 3 statement that mortgage demand for purchasing homes has remained relatively stable despite the elevated environment. He said prospective buyers appear to be adapting to evolving market conditions.
Applications rose by 0.8 percent for the week ending Aug. 28 compared to the prior week, the Mortgage Bankers Association said in a Sept. 2 statement.
The inflation connection
The 12-month inflation reading for July was 3.4 percent, down from 4.2 percent in May but still significantly above February’s 2.4 percent, according to Bureau of Labor Statistics data.
Elevated inflation gives the Federal Reserve reason to maintain or raise its benchmark interest rate, which puts upward pressure on home borrowing costs. The path of inflation through the summer has been partly downward, which would normally support stability, but the movement from 2.4 percent in February to 3.4 percent in July reflects a reacceleration that has complicated the Fed’s calculus.
What elevated mortgage rates mean for buyers
At 6.71 percent, the 30-year fixed makes monthly payments on a median-priced home significantly more expensive than they were below 6 percent earlier in the year. For a $400,000 loan, the difference between 5.9 percent and 6.71 percent amounts to roughly $200 per month, or about $72,000 over the life of the loan.
Buyers who locked in rates below 6 percent in late February and early March are in a different position than those entering now. The gap between what existing homeowners pay and what new buyers face has reinforced the lock-in effect, in which homeowners are reluctant to sell and give up their existing terms, reducing inventory and keeping the market for mortgage-backed homes tighter than the headline numbers suggest.
The outlook
Freddie Mac’s Khater describing demand as relatively stable is a more positive read than the environment alone would suggest. If buyers are adapting rather than leaving the market, the adjustment is happening through changes in budget, location preference and property type rather than through outright withdrawal.
Whether it will fall from 6.71 percent depends primarily on what the Federal Reserve does with its benchmark and how financial markets read the trajectory of inflation and the Iran conflict.
