The US is finally close to taming inflation, with consumer prices falling sharply this year. China is experiencing the opposite problem: People and businesses are not spending, pushing the economy to the verge of a pernicious condition called deflation.

Consumer prices in China, after barely rising for the past several months, fell in July for the first time in more than two years, the country’s National Bureau of Statistics announced on Wednesday. For 10 straight months, the wholesale prices generally paid by businesses to factories and other producers have been down from a year earlier. Real estate prices are tumbling.

Those patterns have amplified concerns about deflation, a potentially crippling pattern of broadly falling prices that tend to also depress the net worth of households — as it did in Japan for years — and make it very hard for borrowers to repay their loans.

Deflation is particularly serious in a country with very high debt, like China.

The Chinese government has pressured economists inside the country not to mention the possibility of deflation, while publicly denying that deflation poses any risk.

“Generally speaking, there is no deflation in Chinese society and there won’t be in the future,” Fu Linghui, a National Bureau of Statistics official, declared at a news briefing on July 17.

It has been nearly eight months since China’s top leader, Xi Jinping, relaxed stringent anti-pandemic measures that had paralysed many parts of the economy. After exhibiting bursts of energy early this year, the Chinese economy, the world’s second largest, has started to slow. Economic policymakers are under increasing pressure to step in to help revive growth, something they have signalled a readiness to do but have not yet carried out in a meaningful way.

“The Chinese economy is squarely facing the spectre of deflation, increasing the urgency of government measures to stimulate the economy and, perhaps more importantly, steps to rebuild household and business confidence,” said Eswar Prasad, an economics professor at Cornell University and former China division chief at the International Monetary Fund.

The prospect of sustained deflation only adds to China’s difficult problems when geopolitical tensions are driving the US and other key economic partners like Germany to seek alternatives to China as a primary source of manufactured goods.

A weak appetite for Chinese goods from domestic and foreign buyers alike, demonstrated by a steep slide in exports this summer, represents a challenge for China, said Wang Dan, the chief economist at Hang Seng Bank China. Low exports are “driven by both slowing demand from the developed world and an effort to diversify supply away from China”, she said.

Consumer prices were down 0.3 per cent in July from a year earlier. They were pulled down by declining food prices — particularly for pork, a staple of the Chinese diet — and falling car prices, the result of a price war and heavy discounting in the auto industry.

Some measures of consumer prices, such those as for clothing, shoes and particularly health care, still showed small increases.

But producer prices declined 4.4 per cent last month from July 2022, as weak demand has forced factories and other businesses to cut prices.

Perhaps most worryingly, particularly in a country where three-fifths of household assets are tied up in real estate, housing prices are falling. According to the Beike Research Institute, a Tianjin firm, prices of existing homes in 100 cities across China have fallen an average of 14 per cent from their peak in August 2021. Rents have fallen 5 per cent.
