WASHINGTON — Signaling continued momentum, an index of home prices for 20 U.S. cities posted the largest year-over-year growth in more than six years, according to data released Tuesday.
The S&P/Case-Shiller 20-city composite index rose 0.3 percent in February, before seasonal adjustment, and was up 9.3 percent from the same period in the prior year, the largest annual growth since May 2006.
February's monthly growth was the largest since August. After seasonal adjustments, prices rose 1.2 percent in February. All 20 cities saw year-over-year gains in February, with accelerating growth in 16 cities.
Areas that were particularly hard hit by the housing market's meltdown are seeing large gains. Phoenix, Ariz., for example, posted the largest year-over-year price growth at 23 percent, while New York had the lowest at 1.9 percent.
Two cities saw record year-over-year price growth. In Atlanta, annual prices were up 16.5 percent, the highest rate since 1992. In Dallas, annual prices were up 7.1 percent, with these data going back to 2001.
After the data's release, Dean Baker, co-director of the Center for Economic and Policy Research, warned about local market bubbles.
"Many of the areas most affected by the housing bubble and subsequent crash are seeing extraordinary price increases," Baker wrote in a research note. "The end of this round of speculation is not likely to be much prettier for the areas affected than the end of the last round."
With ongoing low interest rates, increasing demand and constrained inventory have been supporting prices. The Federal Reserve is expected to keep its interest rate target at near-zero levels when it decides on rates on Wednesday.
Buyers' expectations are also playing a role, according to economists at IHS Global Insight. "Some want-to-be home buyers are entering the market now instead of later because they are afraid that prices will shoot up if they wait. Their expectations, which become self-fulfilling, are magnifying price increases," according to an IHS Global Insight note.
But despite recent gains, the 20-city composite index indicates that prices remain about 29 percent below a 2006 peak.
While there have been recent signs of a pause in the housing market's recovery, data show that residential investment continued to contribute to economic growth in the first quarter, a trend that economists expect to continue this year.
"Despite some recent mixed economic reports for March, housing continues to be one of the brighter spots in the economy," said David Blitzer, chairman of the index committee at S&P Dow Jones Indices.
