U.S. 30-Year Mortgage Rate Rises to 6.66%, Highest in One Year

U.S. mortgage rates have surged to their highest level in nearly a year, as ongoing geopolitical tensions with Iran fuel inflation worries and the Federal Reserve (Fed) holds rates steady while signaling a potential rate hike, putting pressure on the housing market.

Freddie Mac reported on Thursday (the 30th) that the average rate on a 30-year fixed mortgage rose from 6.58% the previous week to 6.66%, marking the highest level since July 31, 2025.

This current rate level represents a significant rebound from the sub-6% low reached at the end of February, with rising energy prices due to Middle East conflicts cited as a key driver.

The Fed announced on Wednesday it would keep its benchmark interest rate unchanged, but three officials voted in favor of a rate hike. As a result, the yield on the 30-year U.S. Treasury bond rose to its highest level in nearly 19 years, while the 10-year Treasury yield hovered near a one-year high.

In terms of market impact, Redfin data shows that pending home sales in the U.S. over the four weeks through July 26 dropped to their lowest level since early April. At the same time, the divergence between luxury home and entry-level home sales has become increasingly pronounced, highlighting deeper economic inequality in the U.S. housing market.

The rise in mortgage rates is closely tied to the recent increase in U.S. Treasury yields, with geopolitical uncertainty serving as a key driving force.

"Peace talks with Iran showed promise in early July, but they have now collapsed," said Anthony Smith, senior economist at Realtor.com. "Markets are reacting again to uncertainty, and the inflationary pressure from rising oil prices due to the conflict is also a factor."

Smith believes the Fed officials' next move is more likely to be a rate hike rather than a cut, making any near-term relief in mortgage rates highly unlikely.
