S&P: US Home Price Decline Accelerates Tuesday September 25, 10:25 am ET By Vinnee Tong, AP Business Writer U.S. Homes Post Steepest Price Drop in 16 Years NEW YORK (AP) -- The decline in U.S. home prices accelerated nationwide in July, posting the steepest drop in 16 years, according to the S&P/Case-Shiller home price index released Tuesday. Home prices have fallen by more every month since the beginning of the year. An index of 10 U.S. cities fell 4.5 percent in July from a year ago. That was the biggest drop since July 1991. S&P Index Committee Chairman David Blitzer said the severe declines may be done by the end of the year. "Maybe the first stage is steep declines, and we're just about done with those," he said. "The second stage is not much gain, not much loss. "The rest of the economy has to catch up to home prices." Yale economist Robert Shiller, who helped create the indices, said in a statement, "The further deceleration in prices is still apparent across the majority of regions." Shiller is also MacroMarkets LLC's chief economist and perhaps is best known for predicting the dot-com bust. A broader index of 20 cities fell 3.9 percent in July over last year, with 15 of 20 cities reporting that prices fell. The five cities where prices are still rising -- Atlanta, Charlotte, N.C., Dallas, Portland and Seattle -- have reported growth is slowing in the past year. Atlanta and Dallas are close to moving into negative territory, S&P said. Shiller, an economist at Yale University, told lawmakers in written comments last week that the loss of a boom mentality among consumers poses a "significant risk" of a recession within the next year. His comments came a day after home buyers and other borrowers got some welcome news when the Federal Reserve cut a key interest rate by half a point to 4.75 percent. It was the Fed's first cut in four years. The housing slowdown and decline in credit availability have triggered worries that the economy could go into a recession, spurring the Fed to act. Economists differ on whether the Fed will again cut rates (and kill the dollar) during two meetings before year's end.
