The average long-term U.S. mortgage rate fell to its lowest level in three-and-a-half years this week, as bond yields rose after oil prices rose due to the war with Iran.
The benchmark 30-year fixed-rate mortgage rate ticked to 6% last week from 5.98%, mortgage broker Freddie Mac said Thursday. A year ago, the rate averaged 6.63%.
The modest increase ends a three-week slide in the average price, which has reached about 6% this year. Last week’s average rate marked the first time it fell below 6% going back to September 2022.
Meanwhile, borrowing costs for 15-year fixed-rate mortgages, which are popular with homeowners refinancing their home loans, fell this week. This average rate fell to 5.43% from 5.44% last week. A year ago, it was at 5.79%, Freddie Mac said.
Mortgage rates are affected by many factors, from the Federal Reserve’s interest rate policy decisions to bond market investors’ expectations for the economy and inflation. They typically track the 10-year Treasury yield, which lenders use as a guide for pricing home loans.
The 10-year Treasury yield was at 4.14% Thursday afternoon, up from about 4% a week ago.
Treasury yields have risen recently as rising oil prices put more upward pressure on inflation, which could keep the Federal Reserve from cutting interest rates.
The central bank does not set mortgage rates, but decisions to raise or lower short-term rates are closely watched by bond investors and can ultimately affect the 10-year Treasury yield, which affects mortgage rates.
“For prices to continue their descent into 2026, we will need clear signals in the coming months that this conflict is not raising prices for consumers at home,” said Joel Brunner, senior economist at Realtor.com. “Given the big jump in oil prices this week and the freight costs that go with it, this positive news on inflation may be difficult.”
Mortgage rates have been low for months, helping lead to a rally in home sales in the final four months of 2025, although the housing market will not recover enough from its slump until 2022, when mortgage rates begin to rise from pandemic-era lows.
US pre-occupied home sales remained at a 30-year low last year. And this year’s buyer-friendly mortgage rates weren’t enough to boost home sales last month.
A sharp rise in home prices, especially in the early years of this decade, and a prolonged national housing shortage exacerbated by years of below-average home construction have driven many interested homeowners out of the market.
