Home Price Gains Slow in July

With today's release of the July S&P/Case-Shiller Home Price Index, we learned that seasonally adjusted home prices for the benchmark 20-city index were up 0.10% 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 0.10% from the previous month. The nonseasonally adjusted index was up 5.9% year-over-year.

Investing.com had forecast a 0.1% MoM seasonally adjusted increase and 6.2% YoY nonseasonally adjusted for the 20-city series.

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

“Rising homes prices are beginning to catch up with housing,” says David M. Blitzer, Managing Director and Chairman of the Index Committee at S&P Dow Jones Indices. “Year-over-year gains and monthly seasonally adjusted increases both slowed in July for the S&P Corelogic Case-Shiller National Index and the 10 and 20-City Composite indices. The slowing is widespread: 15 of 20 cities saw smaller monthly increases in July 2018 than in July 2017. Sales of existing single family homes have dropped each month for the last six months and are now at the level of July 2016. Housing starts rose in August due to strong gains in multifamily construction. The index of housing affordability has worsened substantially since the start of the year.

“Since home prices bottomed in 2012, 12 of the 20 cities tracked by the S&P Corelogic Case-Shiller indices have reached new highs before adjusting for inflation. The eight that remain underwater include the four cities which led the home price boom: Las Vegas, Miami, Phoenix and Tampa. All are enjoying rising prices, especially Las Vegas which currently has the largest year-over-year increases of all 20 cities. The other cities where prices are still not over their earlier peaks are Washington DC, Chicago, New York and Atlanta. [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.
