The average long-term U.S. mortgage rate declined for the fourth week in a row, a sign of relative stability that could potentially open the door for some prospective homebuyers to get back in the market.

Mortgage buyer Freddie Mac reported Thursday that the average on the benchmark 30-year rate fell to 6.09% from 6.13% last week. That’s the lowest level since September. The average rate a year ago was 3.55%.

The average long-term rate reached a two-decade high of 7.08% in late October and early November as the Federal Reserve continued to raise its key lending rate in a bid to cool the economy and tame inflation.

At its first meeting of 2023 Wednesday, the Federal Reserve raised its benchmark lending rate 0.25 percentage points, its eighth increase in less than a year. That pushed the central bank’s key rate to a range of 4.5% to 4.75%, its highest level in 15 years.

While acknowledging that some measures of inflation have eased, Fed Chair Jerome Powell appeared to suggest Wednesday that he foresees two additional quarter-point rate hikes this year.

Though those rate hikes do impact borrowing rates across the board for businesses and families, rates on 30-year mortgages usually track the moves in the 10-year Treasury yield, which lenders use as a guide to pricing loans. Investors’ expectations for future inflation, global demand for U.S. Treasurys and what the Federal Reserve does with interest rates can also influence the cost of borrowing for a home.

The big rise in mortgage rates during the past year has throttled the housing market, with sales of existing homes falling for 11 straight months to the lowest level in more than a decade. Higher rates can add hundreds of a dollars a month in costs for homebuyers, on top of already high home prices.

The National Association of Realtors reported earlier this month that existing U.S. home sales totaled 5.03 million last year, a 17.8% decline from 2021. That is the weakest year for home sales since 2014 and the biggest annual decline since 2008, during the housing crisis of the late 2000s.

Though home prices have retreated as demand has declined, they are still more than 10% higher than a year ago.

The rate for a 15-year mortgage, popular with those refinancing their homes, fell this week to 5.14% from 5.17% last week. It was 2.77% one year ago.
