The Federal Reserve raised its benchmark interest rate on September 16 for the first time in more than three years, and the US housing market has absorbed the decision as one more reason to stand still. Existing home sales remain below a 4.0 million annual rate, contract signings have fallen to a record low, and builder confidence sits at its weakest level since 2012. The result is a market defined less by falling prices than by missing transactions.
A policy reversal, delivered unanimously
The Federal Open Market Committee voted 12 to 0 to raise the target range for the federal funds rate by a quarter percentage point to 3.75% to 4.00%. It was the first increase since July 2023, and it reversed the direction of policy after three rate cuts in the final months of 2025 brought the range down from 4.25% to 4.50%. The committee then held rates steady at five consecutive meetings from January through July 2026 before moving higher in September.
In the Summary of Economic Projections released with the decision, a large majority of officials indicated they expected at least one additional increase before the end of 2026 if inflation does not cool. Chair Kevin Warsh framed the move as a response to price data. “The plain fact is that inflation is too high, and has been for too long,” Warsh said at the post meeting press conference. Analysts at J.P. Morgan Wealth Management called the unanimous vote the committee’s most unified commitment to price stability since Warsh took over as chair, and forecast one further quarter point increase by year end.
Mortgage rates moved before the ink dried
Housing feels Fed policy through the bond market, and the transmission was fast. The average 30-year fixed mortgage rate reached 7.03% in the week ending September 24, the highest level of the year, according to Freddie Mac data reported by Realtor.com. The California Association of Realtors reported that the 30-year fixed rate averaged 6.86% across September as a whole, up from 6.67% in August and 6.35% a year earlier.
At those levels, the arithmetic of a purchase changes materially. Economists note that higher rates price out a measurable share of marginal buyers, while owners holding loans written at far lower rates have a financial incentive to stay put. That combination, often called the lock-in effect, suppresses both demand and supply at the same time.
Sales volumes show a market on pause
The National Association of Realtors reported that existing home sales rose 1.5% in September to a seasonally adjusted annual rate of 3.99 million, a figure that was still 2.2% below a year earlier. NAR’s chief economist noted that August and September were the two slowest months of the year for sales, and that further increases in mortgage rates would leave fewer buyers able to qualify. The forward looking data were weaker: the pending home sales index, which tracks contract signings, fell 7.3% in September to 66.0, the lowest reading since the series began in 2001 and 11.3% below a year earlier.
Inventory explains why prices have not followed volumes down. Unsold inventory stood at 1.60 million homes in September, up 4.6% from a year earlier, equal to 4.8 months of supply. The median existing home price was $417,500, up 1.3% from a year earlier, and the median time on market lengthened to 33 days from 31. Analysts describe the pattern as a freeze rather than a correction: few sellers are under pressure to accept lower prices, and few buyers can transact at the prices sellers will accept.
Builders are discounting into the slowdown
New construction shows the strain more directly. The NAHB/Wells Fargo Housing Market Index fell three points in October to 29, its lowest reading since June 2012, with buyer traffic the weakest component. Forty-three percent of builders reported cutting prices, with the average reduction holding at 6%, and 65% offered sales incentives, the 19th consecutive month in which at least 60% did so. NAHB Chairman Bill Owens cited construction loan costs, materials and diesel prices among the pressures on builders. “Demand persists, but higher mortgage rates, elevated construction costs and weaker consumer confidence are keeping more buyers on the sidelines,” said NAHB Chief Economist Robert Dietz.
The Census Bureau reported that housing starts fell 5.2% in September to a 1.221 million annual rate, 7.4% below a year earlier, while single-family permits declined 4.0% to 845,000, the lowest since March 2023. Builders describe a strategy of discounting current projects rather than starting new ones, a posture economists expect to keep single-family construction subdued into 2027.
The data the Fed is weighing
The September increase rested on inflation data that have refused to settle at the central bank’s 2% target. The Bureau of Labor Statistics reported that the consumer price index rose 3.7% in the twelve months through September, up from 3.4% in August, with gasoline prices climbing 9.1% in the month and the energy index up 20.4% over the year. Core inflation, excluding food and energy, was 2.6% over the year. Shelter costs rose 0.4% in September and 3.2% over the year.
The labor market, by contrast, is cooling. Nonfarm payrolls rose by 29,000 in September, the unemployment rate ticked up to 4.2%, and revisions reduced the previously reported July and August figures by a combined 60,000, with July revised to a loss of 10,000 jobs. Payrolls have grown by an average of 45,000 a month over the past year, and wage growth slowed to 3.0% year over year. Household sentiment has weakened alongside the data. The Conference Board’s Consumer Confidence Index fell 6.7 points in September to 81.9, its lowest level since 2014, while the Expectations Index dropped to 63.6, a level the Conference Board associates with recession risk. Consumers’ average twelve month inflation expectations rose to 6.1%, and 68.4% of respondents expected interest rates to be higher a year from now.
Price data for housing itself tell a two speed story. The S&P Cotality Case-Shiller US National Home Price Index rose 1.93% in the year through July, with the 20-City Composite up 2.47%. Because consumer prices rose faster, national home values fell in inflation adjusted terms for a 14th consecutive month, according to S&P Dow Jones Indices.
What comes next
The committee meets again on October 27 and 28, and the September jobs report shifted market expectations toward a hold at that meeting, even as the September projections pointed to one more increase this year. For housing, analysts say the binding variable is not the policy rate itself but long term yields and the mortgage rates built on them. Until borrowing costs move materially lower, the consensus among housing economists is that the market’s adjustment will continue to arrive through volume rather than price.
FAQ
Why did the Fed raise rates in September 2026? The committee cited inflation that remains above its 2% target. Consumer prices rose 3.7% in the year through September, driven largely by energy, and officials signaled they want a faster return to target.
How does a Fed increase affect mortgage rates? Fixed mortgage rates follow long term Treasury yields more than the federal funds rate directly, but the September increase lifted yields and pushed the average 30-year fixed rate to 7.03% by late September, its highest level of the year.
Are home prices falling? Not nationally on the latest measures. The median existing home price rose 1.3% year over year in September and the Case-Shiller national index rose 1.93% in the year through July, though prices fell after adjusting for inflation.
