S&P/Case-Shiller US Home Price Indices: Data for July shows record declines and a continuation in the trend of double digit falls across many cities in the prices of existing single family homes across the United States. Annual falls in Las Vegas, Phoenix, Miami and Los Angeles at -29.9%, -29.3%, -28.2% and 26.2%.

The chart above depicts the annual returns of the 10-City Composite and the 20-City Composite Home Price Indices. The indices reached new record annual declines of 17.5% and 16.3%, respectively. The 10-City level marked its 10th consecutive monthly report of a record decline, beginning with data reported for October 2007. As depicted on the chart above, during the 1990-92 cycle the record low was -6.3%.

While the annual returns of the two indices continue to reach record lows, the pace of the decline has slowed, particularly over the last three months. For the three months of May thru July, home prices cumulatively fell about 2.2%; whereas for the three months of February thru April, and November 2007 thru January, the cumulative rates of decline were closer to 6.0-6.5%.

“There are signs of a slow down in the rate of decline across the metro areas, but no evidence of a bottom,” says David M. Blitzer, Chairman of the Index Committee at Standard & Poor's. “Little positive news can be found when cities like Las Vegas and Phoenix report annual declines as large as -29.9% and -29.3%, respectively, and all 20 cities are still in negative territory on a year-over-year basis. The Sunbelt continues to be the story, with the seven cities that basically represent that area reporting annual declines roughly between 20 and 30%. While some cities did show some marginal improvement over last month's data, there is still very little evidence of any particular region experiencing an absolute turnaround.”

While there are differences across regions, at the national level the housing market peaked around June/July of 2006. As of July 2008, two years later, the 10-City Composite has fallen by a total of 21.1% and the 20-City Composite is down 19.5%.

Las Vegas remains the weakest market, reporting an annual decline of 29.9%, followed by Phoenix, Miami and Los Angeles at -29.3%, -28.2% and 26.2%, respectively. Atlanta, Dallas, Minneapolis and Tampa showed improvements in their annual and monthly returns, but all four are still too close to their recent lows to determine if the markets have stabilized. While their annual returns are negative, Atlanta, Boston, Dallas, Denver and Minneapolis all reported positive returns for the three months or more.
