Home prices rise most since 2006, pace cools: S&P/Case-Shiller

U.S. single-family home prices rose in May, though the pace of gains cooled compared to the month before, a closely watched survey showed on Tuesday.

The S&P/Case Shiller composite index of 20 metropolitan areas gained 1 percent on a seasonally adjusted basis, shy of economists' forecast for a 1.5 percent increase. That marked a slower pace from April's 1.7 percent rise.

On a non-adjusted basis, prices rose 2.4 percent.

Case-Shiller Index shows best gains in 7 years Robert Shiller, co-founder of the Case-Shiller Index, breaks down the latest numbers on housing and which cities are "bubbling up."

Compared to last May, prices also fell short of expectations, rising 12.2 percent from a year earlier. Still, it was the biggest annual gain since March 2006, matching a record set in April.

The report was unlikely to alter economists' views that the housing sector continues to recover, making it a bright spot for the economy.

"The cities that bubbled in the past are bubbling again," Robert Shiller, economist and co-founder of the S&P/Case-Shiller Home Price Index, told "Squawk on the Street" Tuesday.

"To me, it seems to be at least partly psychological. They've seen it before and they're ready for it again … It seems like California has historically been the most bubbly state in the country and it continues."

Shiller said that the new factor emerging in the numbers is the effect of institutional investors on home prices. "They've learned about momentum and they're saying 'hey, this is it.' The housing market is showing a lot of upward momentum. And you know, I think they're probably right, at least for the short term."

"For a flipper who can get out in about a year, it seems to be a fairly safe bet," he added.

All 20 cities rose on a yearly basis, led by a 24.5 percent surge in San Francisco.

New home sales surge to five-year high despite higher rates

Sales of new U.S. single-family homes vaulted to a five-year high in June, showing little signs of slowing in the face of higher mortgage rates.

The Commerce Department said on Wednesday sales increased 8.3 percent to a seasonally adjusted annual rate of 497,000 units, the highest level since May 2008.

Sales increased 1.3 percent in May.

Economists polled by Reuters had expected new home sales to rise to a 482,000-unit rate last month.

Compared with June last year, sales were up 38.1 percent, the largest increase since January 1992.

The third straight month of gains in new home sales, which are measured when contracts are signed, suggested the housing market was gaining more muscle and should allay concerns that higher mortgage rates could slow down momentum.

Mortgage rates have spiked in anticipation of the U.S. Federal Reserve starting to taper its generous monetary stimulus later this year. Rates still remain low and Fed Chairman Ben Bernanke last week expressed optimism the housing market recovery would continue.

Last month, the inventory of new homes on the market increased 1.3 percent to 161,000, the highest since August 2011, as builders continue to ramp up production to meet the growing demand.

Still, supply remains tight, putting upward pressure on prices. The median new home price increased 7.4 percent from a year ago.

At June's sales pace it would take 3.9 months to clear the houses on the market, down from 4.2 months in May. A supply of 6.0 months is normally considered as a healthy balance between supply and demand.

Sales last month rose in three regions, but fell in the Midwest.
