Many once-hot housing markets around the world are now cooling off, as they start feeling the effects of the U.S.'s financial  and real estate woes.

From the NYT:

The collapse of the housing bubble in the United States is mutating into a global phenomenon, with real estate prices swooning from the Irish countryside and the Spanish coast to Baltic seaports and even parts of northern India.

This synchronized global slowdown, which has become increasingly stark in recent months, is hobbling economic growth worldwide, affecting not just homes but jobs as well.

In Ireland, Spain, Britain and elsewhere, housing markets that soared over the last decade are falling back to earth. Property analysts predict that some countries, like this one, will face an even more wrenching adjustment than that of the United States, including the possibility that the downturn could become a wholesale collapse.

To some extent, the world’s problems are a result of American contagion. As home financing and credit tightens in response to the crisis that began in the subprime mortgage market, analysts worry that other countries could suffer the mortgage defaults and foreclosures that have afflicted California, Florida and other states.

Citing the reverberations of the American housing bust and credit squeeze, the International Monetary Fund last Wednesday cut its forecast for global economic growth this year and warned that the malaise could extend into 2009.

“The problems in the U.S. are being transmitted to Europe,” said Michael Ball, professor of urban and property economics at the University of Reading in Britain, who studies housing prices. “What’s happening now is an awful lot more grief than we expected.” ...

This is not the first housing downturn to cross borders, but its reverberations have been amplified by the integration of financial markets. When faulty American mortgages end up on the books of European banks, the problems of the United States aggravate the world’s problems.

Consider Britain, which had one of Europe’s most robust housing markets, with less of an oversupply than in Ireland or Spain. Then last summer came the subprime crisis across the Atlantic.

Within two months, mortgage approvals dropped 31 percent, compared with the previous year. And by March, average housing prices had fallen 2.5 percent, the largest monthly decline since 1992.

“The boom in house prices was actually much bigger here than in the U.S.,” said Kelvin Davidson, an economist at Capital Economics in London. “If anything, people should be more worried than in the U.S.”

Britain has one of the most developed home-financing industries, not far behind that of the United States. The amount of outstanding mortgage debt, as a share of total economic output, is higher there than in the United States, according to a study by the International Monetary Fund.

“The U.K. followed the U.S. into never-never land, pushing mortgages out the door, believing that prices would go up forever,” said Allan Saunderson, the managing editor of Property Finance Europe, a newsletter for investors.

Still, the problems in Britain pale next to those of Spain and Ireland. Residential investment accounts for 12 percent of the Irish economy and 9 percent of the Spanish economy, compared with 5 percent in Britain and 4 percent in the United States, according to the I.M.F.

The glut of housing has brought new construction to a standstill, driving up unemployment and dimming the prospects for two of Europe’s stellar performers over the last decade.

“We’re waking up from the property dream and finding ourselves in a situation where prices are falling in Spain for the first time,” said Fernando Encinar, a founder of Idealista.com, a real estate Web site.
