S&P/Case-Shiller Home Price Index: "Gains Continue To Weaken"

With today's release of the March S&P/Case-Shiller Home Price Index, we learned that seasonally adjusted home prices for the benchmark 20-city index were up 0.09% 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 0.09% from the previous month. The nonseasonally adjusted index was up 2.7% year-over-year.

Investing.com had forecast a 0.2% MoM seasonally adjusted increase and 3.1% YoY nonseasonally adjusted for the 20-city series.

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

“Home price gains continue to slow,” says David M. Blitzer, Managing Director and Chairman of the Index Committee at S&P Dow Jones Indices. “The patterns seen in the last year or more continue: year-over-year price gains in most cities are consistently shrinking. Double-digit annual gains have vanished. The largest annual gain was 8.2% in Las Vegas; one year ago, Seattle had a 13% gain. In this report, Seattle prices are up only 1.6%. The 20-City Composite dropped from 6.7% to 2.7% annual gains over the last year as well. The shift to smaller price increases is broad-based and not limited to one or two cities where large price increases collapsed. Other housing statistics tell a similar story. Existing single family home sales are flat. Since 2017, peak sales were in February 2018 at 5.1 million at annual rates; the weakest were 4.36 million in January 2019. The range was 650,000."

“Given the broader economic picture, housing should be doing better. Mortgage rates are at 4% for a 30-year fixed rate loan, unemployment is close to a 50-year low, low inflation and moderate increases in real incomes would be expected to support a strong housing market. Measures of household debt service do not reveal any problems and consumer sentiment surveys are upbeat. The difficulty facing housing may be too-high price increases. At the currently lower pace of home price increases, prices
are rising almost twice as fast as inflation: in the last 12 months, the S&P Corelogic Case-Shiller National Index is up 3.7%, double the 1.9% inflation rate. Measured in real, inflation-adjusted terms, home prices today are rising at a 1.8% annual rate. This compares to a 1.2% real annual price increases in housing since 1975.” [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.
