Investors erased $393 billion from China’s benchmark stock index sold the yuan and dumped commodities as fears about the spreading coronavirus and its economic impact drove selling on the first day of trade in China since the Lunar New Year.
A nearly eight per cent plunge on the Shanghai composite index was its biggest daily fall in more than four years.
The Chinese yuan blew past the seven-per-dollar mark and Shanghai-traded commodities from palm oil to copper hit their maximum down limits.
The wipe-out came even as the central bank made its biggest cash injection to the financial system since 2004 and despite apparent regulatory moves to curb selling.
The total number of deaths in China from the coronavirus rose to 361 by Sunday, compared with 17 on Jan. 23, when Chinese markets last traded.
“You wanted to know what a real decoupling from China might look like, or what a ‘What if everyone just stayed at home and didn’t buy anything?’ economic thought-experiment looks like? Well here you are, folks,’’ Rabobank strategist, Michael Every, said in an afternoon note.
The yuan began onshore trade, at its weakest this year, and was down 1.2 per cent by the afternoon, sliding past the symbolic seven-per-dollar level to close at 7.0257.
Shanghai-traded oil, iron ore, copper and soft commodities contracts all posted sharp drops, catching up with sliding global prices.
The new virus has created alarm because it is spreading quickly, much about it is unknown, and authorities’ drastic response is likely to drag on economic growth.
“This will last for some time,’’ said Iris Pang, Greater China economist at ING.
“It’s uncertain whether factory workers or how many of them, will return,’’ she said.
“We haven’t yet seen corporate earnings since the (spread of the) coronavirus.
“Restaurants and retailers may have very little sales.’’
More than 2,500 stocks fell by the daily limit of 10 per cent.
The Shanghai Composite closed down 7.7 per cent at 2,746.6, its lowest since August and a modest recovery from early trade when it was down nearly nine per cent.
Copper sank to its lowest in more than three years, falling by its daily limit of seven per cent, while aluminium, zinc and lead shed more than four per cent and soybeans dropped two per cent.
Bond prices surged, with March futures contracts for 10-year bonds jumping 1.4 per cent.
The People’s Bank of China (PBOC) said the plunge of the stock had irrational or even panic elements, triggered by herd behaviour, in a newspaper commentary published after markets closed.
The sell-off cast a pall over Asia, though losses were contained because a slide had been expected.
Hong Kong’s Hang Seng, which shed almost 10 per cent in two weeks, closed 0.2 per cent firmer.
Amid the sell-down, the PBOC had injected 1.2 trillion yuan ($173.81 billion) into money markets through reverse bond repurchase agreements, the largest such move since 2004, according to DBS analysts.
It also unexpectedly cut the interest rate on those short-term funding facilities by 10 basis points.
The chance of a benchmark lending rate cut on Feb. 20, the date of its next monthly fixing, has significantly increased, central bank adviser, Ma Jun, said.
China’s securities regulator moved to limit short selling and urged mutual fund managers not to sell shares unless they face investor redemptions, sources told Reuters.
“It is a clear message that they want to take growth-supportive measures and keep the market reassured,’’ Mayank Mishra, a macro strategist at Standard Chartered Bank in Singapore, said of the PBOC move.
“They are managing the situation well.
“The timing of the repo rate cut came a little quicker than some people were expecting, but they wanted to send a clear message.’’
Beijing has also said it would help firms that produce vital goods resume work as soon as possible, state broadcaster CCTV said.
Cities like Wuhan, where the virus originated, remain in virtual lockdown and China faces mounting international isolation.
Analysts are beginning to suspect the impact will be greater than the hit from the Severe Acute Respiratory Syndrome (SARS) outbreak in 2002-2003.
That pounded growth across Asia, especially in Hong Kong, and sent the Hang Seng index down by 18 per cent over four months.
Though it quickly rebounded then, China’s share of the global economy has grown fourfold since and, with so many unknowns, few are willing to call a bottom just yet.
“At this point, we don’t see this as a buying opportunity,’’ said Invesco’s David Chao, a global market strategist for Asia ex-Japan.
“We are in the midst of the escalation period.’’
