I knew that there was craziness in the housing market in the States and parts of Asia, but didn't realize that the craziness is global!

The global housing boom | In come the waves | Economist.com: "NEVER before have real house prices risen so fast, for so long, in so many countries. Property markets have been frothing from America, Britain and Australia to France, Spain and China. Rising property prices helped to prop up the world economy after the stockmarket bubble burst in 2000. What if the housing boom now turns to bust?

According to estimates by The Economist, the total value of residential property in developed economies rose by more than $30 trillion over the past five years, to over $70 trillion, an increase equivalent to 100% of those countries' combined GDPs. Not only does this dwarf any previous house-price boom, it is larger than the global stockmarket bubble in the late 1990s (an increase over five years of 80% of GDP) or America's stockmarket bubble in the late 1920s (55% of GDP). In other words, it looks like the biggest bubble in history."

The global boom in house prices has been driven by two common factors: historically low interest rates have encouraged home buyers to borrow more money; and households have lost faith in equities after stockmarkets plunged, making property look attractive. Will prices now fall, or simply flatten off? And in either case, what will be the consequences for economies around the globe? The likely answers to all these questions are not comforting....

While America's housing market is still red hot, others—in Britain, Australia and the Netherlands—have already cooled (see chart 2). What lessons might they offer the United States?

The first is that, contrary to conventional wisdom, it does not require a trigger, such as a big rise in interest rates or unemployment, for house prices to decline....

Another worrying lesson from abroad for America is that even a mere levelling-off of house prices can trigger a sharp slowdown in consumer spending...

The housing market has played such a big role in propping up America's economy that a sharp slowdown in house prices is likely to have severe consequences. Over the past four years, consumer spending and residential construction have together accounted for 90% of the total growth in GDP. And over two-fifths of all private-sector jobs created since 2001 have been in housing-related sectors, such as construction, real estate and mortgage broking...

Japan provides a nasty warning of what can happen when boom turns to bust. Japanese property prices have dropped for 14 years in a row, by 40% from their peak in 1991. Yet the rise in prices in Japan during the decade before 1991 was less than the increase over the past ten years in most of the countries that have experienced housing booms (see chart 3). And it is surely no coincidence that Japan and Germany, the two countries where house prices have fallen for most of the past decade, have had the weakest growth in consumer spending of all developed economies over that period. Americans who believe that house prices can only go up and pose no risk to their economy would be well advised to look overseas.
