BEIJING-- Asian stock markets fell further Monday after the omicron variant of the coronavirus was found in more countries and governments imposed travel controls.

Tokyo, Shanghai, Hong Kong and Sydney declined, though losses were much smaller than Friday’s sharp decline after reports said the variant first spotted in South Africa appeared to be spreading around the globe.

On Friday, Wall Street’s benchmark S&P 500 index fell 2.3 percent for its biggest daily loss since February. Investors sold banks, energy and airline stocks and shifted money into bonds and other safe haven assets.

“Financial market volatility will likely persist through this week,” said Venkateswaran Lavanya of Mizuho Bank in a report.

The Shanghai Composite Index lost less than 0.1 percent to 3,561.94 and the Nikkei 225 in Tokyo shed less than 0.1 percent to 28,746.49. The Hang Seng in Hong Kong sank 0.8 percent to 23,876.74.

The Kospi in Seoul declined 0.5 percent to 2,922.25 and Sydney’s S&P-ASX 200 retreated 0.3 percent to 7,259.20. New Zealand and Southeast Asian markets also were lower.

It is unclear whether the omicron variant is more dangerous than earlier versions, though the World Health Organization called it “highly transmissible.”

Governments have imposed new travel controls, fueling investor fears about possible setbacks in containing the pandemic that has killed more than 5 million people since the first cases in late 2019.

Japanese Prime Minister Fumio Kishida on Monday announced the government will halt as of Nov. 30 its recent change to its border control policies that had allowed foreign business travelers and trainees to enter the country after a long, pandemic-related hiatus.

The new variant has been found in Hong Kong, Belgium and Tel Aviv and South African cities including Johannesburg. The European Union, the United States and Britain imposed curbs on travel from Africa. Israel banned entry by foreigners.

Also Monday, Japan’s government reported retail sales rose 1.1 percent in October over the previous month. Vehicle sales fell 6.7 percent.

On Friday, the S&P 500 index dropped 106.84 points to 4,594.62. The Dow Jones Industrial Average lost 905.04 points, or 2.5 percent, to 34,899.34 after falling more than 1,000 at one point. The Nasdaq Composite lost 2.2 percent, to 15,491.66.

Exxon fell 3.5 percent while Chevron shed 2.3 percent. JPMorgan Chase dropped 3 percent.

United Airlines gave up 9.6 percent and American Airlines declined 8.8 percent.

Vaccine makers benefited. Pfizer shares rose more than 6 percent while Moderna shares jumped more than 20 percent.

Investors shifted money into bonds and companies that benefited from previous rounds of anti-disease controls. Online meetings service company Zoom Communications rose nearly 6 percent.

The omicron variant might complicate planning by central banks that are deciding when and how to withdraw stimulus that is boosting stock prices.

Investors were rattled last week when notes from the Federal Reserve’s October meeting showed officials said they were ready to consider raising interest rates sooner than planned in response to higher inflation. The Fed previously said its first rate hike might not come until late 2022.

In energy markets, benchmark U.S. crude surged $3.70 to $71.85 per barrel in electronic trading on the New York Mercantile Exchange, rebounding from Friday’s $10.24 plunge. Brent crude jumped $3.38 to $74.97 per barrel in London.

The dollar rose to 113.68 Japanese yen from Friday’s 113.19 yen. The euro rose to $1.1280 from $1.1319.
