NEW YORK, Oct. 28, 2025 /PRNewswire/ -- S&P Dow Jones Indices (S&P DJI) today released the August 2025 results for the S&P Cotality Case-Shiller Indices.

ANALYSIS

"August's data shows U.S. home prices continuing to slow, with the National Index up just 1.5% year-over-year," said Nicholas Godec, CFA, CAIA, CIPM, Head of Fixed Income Tradables & Commodities at S&P Dow Jones Indices. "This marks the weakest annual gain in over two years and falls well below the 3% inflation rate. For the fourth straight month, home values have lost ground to inflation, meaning homeowners are seeing their real wealth decline even as nominal prices inch higher.

"The National Index rose 1.5% over the past year, with most of that gain coming in the recent six months (up 1.5%) while the prior six months were essentially flat. The 20-City Composite gained 1.6% annually and the 10-City rose 2.1%, both continuing their deceleration from earlier in the year..

"New York again led all metros with a 6.1% annual gain, followed by Chicago at 5.9% and Cleveland at 4.7%. These Midwest and Northeast markets, which saw modest gains during the pandemic, continue to outperform. At the other end, Tampa fell 3.3% year over year, Phoenix dropped 1.7%, and Miami declined 1.7%. Several Western markets also posted losses: San Francisco fell 1.5%, Denver dropped 0.7%, and San Diego declined 0.7%. Seattle turned slightly negative at -0.1%.3"Monthly data for August was weak across the board. Nineteen of 20 cities saw price declines before seasonal adjustment, with only Chicago posting a gain. The National Index fell 0.3% for the month, while both the 10-City and 20-City Composites dropped 0.6%. After seasonal adjustment, all three indices remained negative, suggesting weakness beyond normal seasonal patterns. Phoenix fell 0.9% in August alone, while Los Angeles, Portland, and Denver each dropped between 0.7% and 1.0%.

"Mortgage rates remaining above 6.5% continue to weigh on buyer demand, even during what should be the busy summer season. The combination of high financing costs and prices that remain near record highs has limited transaction activity. Markets that experienced the sharpest pandemic-era gains are now seeing the largest corrections, while more affordable metros with stable local economies are holding up better. Looking ahead, the housing market appears to be finding a new equilibrium after the pandemic boom," Godec concluded. "With price growth running at half the rate of inflation and several major markets in decline, the rapid appreciation of recent years has clearly ended. This adjustment may ultimately lead to a more sustainable market, but for now, homeowners are watching their real equity erode while buyers face the dual challenge of elevated prices and high borrowing costs."

The S&P Cotality Case-Shiller Indices are published on the last Tuesday of each month at 9:00 am ET. They are constructed to accurately track the price path of typical single-family homes located in each metropolitan area provided. Each index combines matched price pairs for thousands of individual houses from the available universe of arms-length sales data. The S&P Cotality Case-Shiller U.S. National Home Price Index tracks the value of single-family housing within the United States. The index is a composite of single-family home price indices for the nine U.S. Census divisions and is calculated quarterly. The S&P Cotality Case-Shiller 10-City Composite Home Price Index is a value-weighted average of the 10 original metro area indices. The S&P Cotality Case-Shiller 20-City Composite Home Price Index is a value-weighted average of the 20 metro area indices. The indices have a base value of 100 in January 2000; thus, for example, a current index value of 150 translates to a 50% appreciation rate since January 2000 for a typical home located within the subject market.
