Mortgage rates today September 25: 30-year rises above 7.4%, 15-year climbs to 6.647% - here’s what borrowers need to know and why mortgage rates are going higher

Mortgage rates today September 25: Mortgage rates moved higher today, with the average rate on a 30-year purchase mortgage rising to 7.477%, up from 7.317% a day earlier, as per Zillow data.

The latest increase comes as Treasury yields remain elevated and investors continue to react to expectations surrounding the Federal Reserve's interest-rate policy. So that means, for homeowners looking to refinance, rates are also higher. The average 30-year refinance rate is 7.588% and the 15-year refinance rate is 6.648%.

Why Are Mortgage Rates Going Up

Mortgage rates tend to follow the yield on 10-year US Treasury notes. According to US News, those yields recently climbed to their highest level since 2007 as markets prepared for the Federal Reserve's September meeting and priced in a rate hike.

The Fed does not directly set mortgage rates. Its monetary policy, however, can influence the direction of borrowing costs.

Treasury yields can also move before the Fed actually changes rates because investors respond to expectations about what the central bank might do next.

That was evident on September 23, when 10-year Treasury yields jumped after Federal Reserve Board member Michael S. Barr spoke at a housing policy summit in Chicago. Barr said more rate hikes were likely to be needed to bring inflation down to the Fed's target in a timely manner.

At the same time, Barr noted that monetary policy could eventually help ease some of the pressure on mortgage rates. He pointed out that mortgage rates are generally lower when inflation is lower.

Oil Prices and Inflation Are Also Playing a Role

The latest mortgage-rate moves are also tied to broader inflation concerns.

As per the US News, mortgage rates have risen since the beginning of the US war in Iran in late February. When the conflict has shown signs of intensifying, mortgage rates and 10-year Treasury yields have tended to move higher. When the conflict has appeared closer to a resolution, both have declined.

Oil prices are an important part of that relationship. Higher energy costs can raise the cost of manufacturing and transportation, putting additional pressure on inflation. Higher inflation can then contribute to higher interest rates.

The August consumer price index report showed inflation running at an annual rate of 3.4%. US News attributed much of the elevated reading to higher energy costs as the war in Iran pushed up oil prices.

Mortgage Rates Could Stay Above 6%

For borrowers hoping for a quick return to much lower mortgage rates, the outlook remains challenging.

US News reported that most experts expect mortgage rates to remain relatively elevated over the next few years, with 30-year fixed rates staying above 6%.

There is always a possibility that an unexpected change in the US economy could send rates lower. However, US News noted that rates falling below 3% or even 4% is unlikely in the foreseeable future.

In the longer term, bringing inflation under control could help reduce pressure on mortgage rates. But that is a process measured in months rather than days.

Mortgage Rates Remain Well Above 2021 Levels

Today's rates are far removed from the historically low levels seen earlier in the decade.

As per Freddie Mac data cited by US News, the 30-year fixed mortgage rate dropped to a record low of 2.65% in January 2021. Rates later climbed to nearly 8% in October 2023 before settling around 7%.

Freddie Mac has tracked weekly mortgage rates since 1971, with the median mortgage rate over that period standing at 7.23%.

The current 30-year purchase rate of 7.477% is therefore above that long-term median, although it remains well below the record high of 18.63% recorded in 1981.
