S&P/Case-Shiller Home Price Index: "Annual Home Price Gains Dip To 3.4%"

With today's release of the May S&P/Case-Shiller Home Price Index, we learned that seasonally adjusted home prices for the benchmark 20-city index were up 0.14% month over month. The seasonally adjusted national index year-over-year change has hovered between 4.2% and 6.7% for the last two-plus years. Today's S&P/Case-Shiller National Home Price Index (nominal) reached another new high.

The adjacent column chart illustrates the month-over-month change in the seasonally adjusted 20-city index, which tends to be the most closely watched of the Case-Shiller series. It was up 0.14% from the previous month. The nonseasonally adjusted index was up 2.4% year-over-year.

Investing.com had forecast a 0.1% MoM seasonally adjusted increase and 2.4% YoY nonseasonally adjusted for the 20-city series.

Here is an excerpt from the analysis in today's Standard & Poor's press release.

“Nationally, year-over-year home price gains were lower in May than in April, but not dramatically so and a broad-based moderation continued,” says Philip Murphy, Managing Director and Global Head of Index Governance at S&P Dow Jones Indices. Among 20 major U.S. city home price indices, the average YOY gain has been declining for the past year or so and now stands at the moderate nominal YOY rate of 3.1%.

“Though home price gains seem generally sustainable for the time being, there are significant variations between YOY rates of change in individual cities. Seattle’s home price index is now 1.2% lower than it was in May 2018, the first negative YOY change recorded in a major city in a number of years. On the other hand, Las Vegas and Phoenix, while cooler than they were during 2018, remain quite strong at 6.4% and 5.7% YOY gains, respectively. Whether negative YOY rates of change spread to other cities remains to be seen; for now, there is still substantial diversity in local trends. Nationally, increasing housing supply points to somewhat weakened demand, but the fact that seven cities experienced stronger YOY price gains in May than they did in April suggests an underlying resiliency that may mitigate the risk of overshooting to the downside at the national level.” [Link to source]

The chart below is an overlay of the Case-Shiller 10- and 20-City Composite Indexes along with the national index since 1987, the first year that the 10-City Composite was tracked. Note that the 20-City, which is probably the most closely watched of the three, dates from 2000. We've used the seasonally adjusted data for this illustration.

For a long-term perspective on home prices, here is a look at the seasonally and inflation-adjusted Case-Shiller price index from 1953, the first year that monthly data is available. Because the CPI owners' equivalent rent of residences didn't start until 1983, we've used the broader seasonally adjusted Consumer Price Index.

To get an even better idea of the trend in housing prices over long time periods, we compare the change in the seasonally-adjusted Case-Shiller Home Price Index and the Consumer Price Index since 1953.
