Home prices in the 20 biggest U.S. cities rose 1.3 percent in May from a month earlier, as showed by the Standard & Poor's/Case- Shiller home price index. But this increase was mainly fueled by the residual impact from the homebuyers' tax credit, which affects purchases that close through the end of June.
The collapse of the U.S. housing market triggered the worst financial crisis since the 1930s. While other sectors, including manufacture, service and financial industry, have shown gradual improvements since recovery began in the second half of last year, housing market seems to be stubbornly sluggish and continues to drag down the fragile economic recovery.
The International Monetary Fund recently warned that even though the agency does not see the possibility of a return of economic recession, there is the real risk of a "double dip" in the housing market.
