China’s southern megacities of Guangzhou and Shenzhen are the latest centers to impose new measures to cool their overheated real estate markets, including higher mortgage down payments and home purchase restrictions.
A property boom has given a welcome boost to China’s economy this year, fueling demand for everything from construction materials to furniture, but a growing buying frenzy is adding to worries about ever-rising debt and risks to the banking system.
The new measures are the latest steps to tighten credit flowing into the property sector as the government tries to balance the need to prevent bubbles while stimulating economic growth.
Prices for new homes in the booming tech centre of Shenzhen rose 36.8% from a year ago in August, while Guangzhou’s new home prices rose 21.1% over that period, National Bureau of Statistics (NBS) data showed.
Other cities including Chengdu, Jinan, Wuhan and Zhengzhou have already announced new restrictions on property purchases as the government tries to dampen prices stoked by property speculators in second- and third-tier cities across the country.
The average new home price in 70 major cities climbed an annual 9.2% in August, up from 7.9% in July, according to the National Bureau of Statistics.
Nomura analysts said the new measures were expected to help cool frothy prices in the biggest cities and should prevent the market frenzy from spilling over into smaller cities.
“We also believe it unlikely that the latest tightening measures will cause the bubble to burst, sparking a collapse of home prices. We envision a more likely scenario to be a mild retreat or prolonged flattening of home prices in tier-1 cities,” they said in a note on Tuesday.
First-time home buyers in Shenzhen will face minimum down payments of 30%, but deposits for others will be raised to no less than 50%, state news agency Xinhua quoted a government document as saying.
Down payments for second-home buyers in China’s southern Guangdong province near Hong Kong will be increased to no less than 70%, Xinhua said without giving further details.
