The average long-term U.S. mortgage rate experienced its second consecutive weekly increase, climbing back to levels last observed four weeks ago. The benchmark 30-year fixed-rate mortgage reached 6.37% this week, up from 6.3% a week prior, reflecting ongoing bond market volatility and growing inflation concerns fueled by surging oil prices amid the war with Iran, according to mortgage buyer Freddie Mac.
Mortgage Rates Rebound Amid Market Volatility
This recent uptick marks a significant shift, as the average 30-year fixed rate had previously slipped just under 6% in late February for the first time since late 2022, a threshold it has not fallen below since. While the current rate of 6.37% remains below the 6.76% average recorded one year ago, the consistent rise over the past two weeks signals renewed pressure on borrowing costs.
Borrowing costs for 15-year fixed-rate mortgages, often favored by homeowners refinancing their home loans, also moved higher this week. The average rate for these loans rose to 5.72% from 5.64% last week. A year ago, it was at 5.89%, Freddie Mac reported on Thursday, May 7, 2026.
Inflationary Pressures and Bond Market Dynamics
The upward trajectory in mortgage rates is directly influenced by a confluence of economic factors. These include the Federal Reserve’s interest rate policy decisions and, critically, bond market investors’ expectations regarding the broader economy and inflation. The trajectory of the average 30-year home loan rate closely mirrors that of U.S. 10-year Treasury bond yields, which lenders utilize as a primary guide for pricing home loans.
In midday trading Thursday, the 10-year Treasury yield stood at 4.37% on the bond market. This represents a notable increase from late February, when the yield was just 3.97%, prior to the outbreak of the war with Iran. The surging oil prices, a direct consequence of the conflict, are intensifying inflation worries, which in turn contribute to the bond market volatility observed this week.
Impact on Housing Market and Homebuyers
The rising cost of borrowing carries substantial implications for the U.S. housing market, particularly for prospective homebuyers. An increase in mortgage rates can add hundreds of dollars to monthly housing costs, thereby limiting the purchasing power and affordability for many individuals. This financial squeeze has already contributed to a lackluster start to the spring homebuying season, traditionally the busiest period for the housing market.
Sales of previously occupied U.S. homes have been down from a year earlier throughout the first three months of the current year. This extends a nationwide housing slump that originated in 2022, a period when mortgage rates first began their ascent from the historic lows observed during the pandemic era. The ongoing rate volatility, coupled with other economic fallout stemming from the Middle East conflict, continues to weigh on market activity.
