Housing prices in biggest bubble in history

The Economist

The worldwide rise in house prices is the biggest bubble in history. Prepare for the economic pain when it pops.

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 most compelling evidence that home prices are over-valued in many countries is the diverging relationship between house prices and rents. Calculations by The Economist show that house prices have hit record levels in relation to rents in America, Britain, Australia, New Zealand, France, Spain, the Netherlands, Ireland and Belgium. This suggests that homes are even more over-valued than at previous peaks, from which prices typically fell in real terms. House prices are also at record levels in relation to incomes in these nine countries.

America's housing market heated up later than those in other countries, such as Britain and Australia, but it is now looking more and more similar. Even the Federal Reserve is at last starting to fret about what is happening. Prices are being driven by speculative demand. A study by the National Association of Realtors (NAR) found that 23% of all American houses bought in 2004 were for investment, not owner-occupation. Another 13% were bought as second homes. Investors are prepared to buy houses they will rent out at a loss, just because they think prices will keep rising—the very definition of a financial bubble.
