The government’s inflation gauge and the country’s most closely watched home-price index moved in opposite directions again in June, and the gap between them has now persisted for more than a year. S&P Dow Jones Indices reported on August 25 that its national home price index rose 1.5 percent from a year earlier in June, an improvement from May’s 1.2 percent pace but still well short of the 3.5 percent inflation rate recorded the same month. For anyone counting on home equity as the biggest asset in a household’s net worth, that gap means the typical house is still worth less in real purchasing power than it was a year ago, even as the sale price written on paper keeps climbing.
What the August 25 Case-Shiller Release Shows
The S&P Cotality Case-Shiller U.S. National Home Price Index, which tracks repeat sales of single-family homes across the country, posted its thirteenth straight month of decline in real, inflation-adjusted terms in June. Rebecca Kaufman, Associate Director of Commodities at S&P Dow Jones Indices, described June’s numbers as a partial reprieve rather than a reversal: inflation cooled to 3.5 percent while the national index’s annual gain ticked up from May, narrowing the real-terms erosion slightly without ending it. The broader composites moved similarly: the 20-City Composite rose 2.1 percent year over year, up from 1.6 percent in May, and the 10-City Composite rose 2.9 percent, up from 2.4 percent.

The Nearly Nine-Point Gap Between the Best and Worst Metros
National averages hide how differently this is playing out city to city. Chicago posted the strongest annual gain among the 20 tracked cities for the fourth straight month, up 6.9 percent in June, followed by New York at 4.8 percent and Cleveland at 4.1 percent. At the other end, Seattle posted the weakest reading at a 2.0 percent annual decline, with Las Vegas down 1.9 percent and Denver down 1.2 percent. That’s nearly a nine-percentage-point spread between the strongest and weakest major markets in a single month, and it lines up with a pattern S&P’s own analysts describe as a years-long divide: Northeast and Midwest markets regaining strength while several Western and Sunbelt markets soften.
Month over month, the pattern held too: on a non-seasonally adjusted basis, both the National Index and the 20-City Composite gained 0.4 percent from May to June, a normal seasonal bump since June sits near the peak of the traditional homebuying season. After seasonal adjustment strips that summer effect out, the National Index gained just 0.1 percent for the month and the 20-City Composite gained 0.3 percent, a reminder that even the modest annual gains reported this month are smaller once the usual summer sales rush is accounted for.
Why “Rising” Prices Still Add Up to Losing Ground
A home price index measuring a 1.5 percent nominal gain sounds like appreciation, and technically it is. The real-terms comparison is what changes the picture: when the cost of everything else a household buys is climbing 3.5 percent a year and the value of a home is climbing only 1.5 percent, the home is quietly losing purchasing power relative to the rest of the economy even as its sale price rises. That’s been true for thirteen consecutive months now, according to the index. Financing costs are a big part of why buyers aren’t bidding prices up faster: 30-year mortgage rates were holding near 6.5 percent in June, which S&P’s Kaufman pointed to directly as a reason current homeowners are staying put rather than giving up mortgages they locked in at lower rates in prior years, thinning out the supply of homes actually changing hands. Freddie Mac’s own weekly rate survey confirms the range, with the 30-year fixed rate holding between roughly 6.48 percent and 6.52 percent across June, essentially flat for the month. That stability cuts both ways for households: it means financing costs aren’t adding fresh pressure on top of already-slow price growth, but it also means the relief homeowners locked out of the market are waiting for hasn’t arrived yet either.
What It Means for Owners, Buyers and Household Net Worth
For a household that already owns a home, the practical effect shows up on paper rather than in a monthly bill: the index that measures the single-family housing market covering all nine census divisions now sits 9.3 percent above its 2022 peak and 15 percent above its 2023 trough nationally, according to S&P’s own index data, so most owners still show a gain since the last downturn even while losing ground to inflation month over month. For a prospective buyer, the mortgage-rate story matters more directly than the price index itself: a home costing 1.5 percent more than a year ago, financed at a rate holding near 6.5 percent, is a materially different monthly payment than the same home purchased when rates were lower, regardless of what the index headline says. And for anyone selling in one of the softer metros, Seattle, Las Vegas or Denver among them, a falling year-over-year number means listing into a market where the comparable sale six or twelve months ago may simply no longer be achievable.
