China’s property market is in freefall. What does this mean for the world economy? | Keyu Jin

The sector is dangerously overheated - but unlike the 2008 financial crisis, the global ripple effect is likely to be limited

The property sector in the Chinese economy has always been something of a puzzle. At its peak, it accounted for a quarter of the nation's economic output, broadly measured. And it sees people in Beijing and Shanghai paying house prices similar to those in San Francisco and New York, despite having just a quarter the income of American buyers.

Now many believe that we are about to see a violent contraction of the property market in China. The government wants to intervene to curb speculation, and rein in what it calls the three high" problem: high prices, high debt and high financialisation. The approach has been nothing short of dramatic. Financing for property developers has tanked. Earlier this year, property sales declined by as much as 20-30%, in-progress developments are not being completed and people have taken to the streets, banding together to stop mortgage payments on such projects in protest.
