Chinese markets fell on Wednesday as global investors continue to deal with the aftermath of Federal Reserve chair Jerome Powell’s hawkish speech at Jackson Hole last week, and the alarming spread of Covid in China.
Investor mood was also hit by new official data from China that showed factory activity continued to contract in the world’s second largest economy following strict Covid lockdowns and a record heat wave.
Mainland China’s benchmark Shanghai Composite Index dropped 0.8% to close at its lowest level in four weeks. So far this year, the index has tumbled nearly 12%.
The tech-heavy Shenzhen Component Index also fell 1.3% to its worst level in more than two months.
Chinese electric car and battery maker BYD
(BYDDF) plunged 8% in Hong Kong, after Warren Buffett’s Berkshire Hathaway
(BRKA) said in a filing that it had sold around 1.33 million Hong Kong-listed shares of BYD
(BYDDF) for 370 million Hong Kong dollars ($47 million).
After the sale, Berkshire’s stake in BYD has dropped to 19.92% from 20.04%. The news followed weeks of speculations that Buffett might give up on the biggest home-grown EV maker in China, which is nipping at Tesla’s heels.
The losses in Chinese stocks came as the country battles an intensive wave of Covid outbreaks. All mainland Chinese provinces have identified locally transmitted Covid-19 cases in the past 10 days, according to CNN’s calculations based on data from the National Health Commission.
The fast spread of cases has sparked worries about more lockdowns. Earlier this year, China placed Shanghai and other key cities under strict lockdowns for months, hammering consumer activity and disrupting global supply chains.
Earlier this week, authorities in Shenzhen, the country’s technology hub, shut down the world’s largest electronics market of Huaqiangbei and suspended public transport nearby in response to a small number of Covid cases.
“The implementation of virus restrictions in several parts of [China’s] biggest cities continues to highlight its struggle in containing spreads,” said Yeap Jun Rong, a market strategist at IG Group, adding that Beijing’s tough stance on zero-Covid means the country’s growth prospect could remain subdued.
Also upsetting investors is news that China’s massive manufacturing industry continued to shrink in August amid the country’s worst heat wave in six decades.
A government survey released on Monday showed that the manufacturing Purchasing Managers’ Index rose to 49.4 in August from 49 in July, but remained in contraction territory. The 50-point mark separates contraction from growth.
“Economic activities stayed weak in August, partly due to power shortage caused by heat waves,” said Zhiwei Zhang, president and chief economist at Pinpoint Asset Management, in a note on Wednesday.
A record heat wave and drought have swept across southern China in the past month, causing power outages in industrial heartlands and disrupting factory operations for several international businesses, such as Tesla
(TSLA) and Toyota.
The power crisis has eased this week, with energy supply to industrial users being restored in Sichuan and Chongqing. But the main constraint for the economy — the zero-Covid policy — has not been removed, analysts warned.
“The disruption from the power shortages is now receding,” but the Covid situation is “worsening again,” wrote Julian Evans-Pritchard, senior China economist for Capital Economics, in a report on Wednesday.
“For now, the resulting disruption appears modest but the threat of damaging lockdowns is growing,” he said.
