Stocks in mainland China plummeted more than 7% on Monday as they returned to trade following an extended holiday amid an ongoing coronavirus outbreak.
The Shanghai composite fell 7.72% to close at about 2,746.61 while the Shenzhen component dropped 8.45% to end its trading day about 9,779.67. The Shenzhen composite also declined 8.414% to close at around 1,609.00. The indexes all fell around 9% in early trade during the session.
The moves on the mainland came following an extended holiday amid an ongoing virus outbreak that has taken more than 300 lives in the country so far.
The People's Bank of China announced Sunday that it will inject 1.2 trillion yuan (approx. $173 billion) worth of liquidity into the markets via open market reverse repo operations. The Chinese central bank said the overall liquidity in the system would be 900 billion yuan (approx. $130 billion) more as compared to the same period last year.
"While this will be the largest single-day addition since 2004, it implies a mere net injection of RMB150bn as commercial banks are scheduled to repay RMB1.05tn of funds on Monday," strategists at Singapore's DBS Group Research wrote in a note. "The authority may need to inject more cash in the rest of the week via reverse repo and/or medium-term lending facility to soothe market nerves."
"(The Chinese government) may have another kind of rate cut … or RRR cut. But honestly speaking … it can only (help) a little bit at this moment," Dickie Wong, executive director at Kingston Securities, told CNBC's "Street Signs" on Monday.
Comparing it to the situation two months ago when concerns largely centered around trade frictions between Beijing and Washington, Wong said Chinese officials and the government had "more tools" then to tackle problems.
At the moment, however, he said: "The first priority amongst all priorities would definitely (be) to solve this virus outbreak."
Overall, the MSCI Asia ex-Japan index was 0.81% lower.
A private survey of China's manufacturing activity also came in on Monday, showing it expanded in January, with the Markit/Caixin manufacturing Purchasing Managers' Index (PMI) for January at 51.1. That was below expectations of 51.3 by economists in a Reuters poll. The PMI figure for December was 51.5. PMI readings above 50 indicate expansion, while those below that level signal contraction.
On Friday, China's National Bureau of Statistics said the country's official manufacturing PMI came in at 50.0 for the month of January — an indication of stalled activity. The bureau said that the impact of the ongoing coronavirus outbreak was not fully reflected in the survey, which was conducted before Jan. 20.
Investors have been closely tracking the coronavirus outbreak in recent days. Stocks on Wall Street plunged on Friday amid concerns over the virus' potential economic impact, with the Dow Jones Industrial Average's gains for January being wiped out as it plummeted about 600 points.
The U.S. dollar index, which tracks the greenback against a basket of its peers, was at 97.486 after declining from levels above 97.8 last week.
