Year-over-Year

The S&P/Case-Shiller U.S. National Home Price Index, covering all nine U.S. census divisions, recorded a slightly higher year-over-year gain with a 4.5% annual increase in June 2015 versus a 4.4% increase in May 2015. The 10-City Composite had marginally lower year-over-year gains, with an increase of 4.6% year-over-year. The 20-City Composite year-over-year pace was virtually unchanged from last month, rising 5.0% year-over-year.

Denver, San Francisco, and Dallas reported the highest year-over-year gains among the 20 cities with price increases of 10.2%, 9.5%, and 8.2%, respectively. Eleven cities reported greater price increases in the year ending June 2015 over the year ending May 2015.  Denver is the only city with a double digit increase, and Phoenix and Detroit had the longest streaks of year-over-year increases. Phoenix reported a 4.1% in June 2015, the seventh consecutive year-over-year increase. Detroit recorded 5.7% in June 2015, the sixth consecutive year-over-year increase.

Month-over-Month

Before seasonal adjustment, the National index and 20-City Composite both reported gains of 1.0% month-over-month in June. The 10-City Composite posted a gain of 0.9% month-over-month. After seasonal adjustment, the National index posted a gain of 0.1% while the 10-City and 20-City Composites were both down 0.1% month-over-month. All 20 cities reported increases in June before seasonal adjustment; after seasonal adjustment, nine were down, nine were up, and two were unchanged.

Analysis

"Nationally, home prices continue to rise at a 4-5% annual rate, two to three times the rate of inflation," says David M. Blitzer, Managing Director and Chairman of the Index Committee at S&P Dow Jones Indices. "While prices in San Francisco and Denver are rising far faster than those in Washington DC, New York, or Cleveland, the city-to-city price patterns are little changed in the last year. Washington saw the smallest year-over-year gains in five of the last six months; San Francisco and Denver ranked either first or second of all cities in the last five months. The price gains have been consistent as the unemployment rate declined with steady inflation and an unchanged Fed policy.

"The missing piece in the housing picture has been housing starts and sales. These have changed for the better in the last few months. Sales of existing homes reached 5.6 million at annual rates in July, the strongest figure since 2007. Housing starts topped 1.2 million units at annual rates with almost two-thirds of the total in single family homes. Sales of new homes are also trending higher. These data point to a stronger housing sector to support the economy. Two possible clouds on the horizon are a possible Fed rate increase and volatility in the stock market.  A one quarter-point increase in the Fed funds rate won't derail housing. However, if the Fed were to quickly follow that initial move with one or two more rate increases, housing and home prices might suffer. A stock market correction is unlikely to do much damage to the housing market; a full blown bear market dropping more than 20% would present some difficulties for housing and for other economic sectors."

Table 2 below shows a summary of the monthly changes using the seasonally adjusted and non-seasonally adjusted (NSA) data. Since its launch in early 2006, the S&P/Case-Shiller Home Price Indices have published, and the markets have followed and reported on, the non-seasonally adjusted data set used in the headline indices. For analytical purposes, S&P Dow Jones Indices publishes a seasonally adjusted data set covered in the headline indices, as well as for the 17 of 20 markets with tiered price indices and the five condo markets that are tracked.
