US 30-year mortgage rates hit highest level since June 2025

The average interest rate on 30-year fixed-rate mortgages in the United States climbed to its highest level since June 2025 last week, as rising oil prices and renewed inflation concerns pushed borrowing costs higher.

According to the Mortgage Bankers Association (MBA), the average rate increased by six basis points to 6.85% during the week ending September 4, 2026. The rise adds further pressure to prospective homebuyers already facing elevated housing and financing costs.

Mortgage rates are closely linked to movements in US Treasury yields. Those yields have increased in recent weeks amid concerns over the country’s growing public debt, which surpassed $40 trillion in August, as well as competition for capital from companies investing heavily in infrastructure related to artificial intelligence.

Inflation has also become a growing concern as the conflict between the United States and Iran threatens to push energy prices higher. Consumer price pressures have remained above the Federal Reserve’s 2% target for more than five years, complicating decisions over the future direction of monetary policy.

Higher mortgage rates have already weakened demand for refinancing. MBA data showed that refinancing applications fell 6.2% from the previous week, while total mortgage applications, including home purchases and refinancing, declined by 2.7%.

Borrowers are facing little immediate relief, with the yield on the benchmark 10-year US Treasury note approaching 4.8% on Tuesday, its highest level since October 2023. Because mortgage rates tend to move in response to longer-term Treasury yields, sustained increases could keep housing finance costs elevated.

Markets are closely watching inflation data due later this week for indications about the Federal Reserve’s next policy decision. Producer price data are scheduled for Thursday, followed by the consumer price index on Friday. The figures could significantly influence expectations ahead of the Federal Reserve’s September 15-16 meeting.

At present, financial markets are increasingly pricing in the possibility of an interest-rate increase rather than a decision to leave borrowing costs unchanged. However, a weaker-than-expected inflation reading could quickly alter those expectations.

The outlook also puts the Federal Reserve under political pressure, as President Donald Trump has repeatedly called for lower interest rates. For now, however, policymakers face the challenge of balancing economic growth and housing affordability against persistent inflation risks and higher energy costs.
