China shares plunged Tuesday, with investors rushing to sell late in the session, while other Asian markets succumbed to tumbling oil prices.

The Shanghai Composite Index, China's main benchmark, finished down 6.4% at 2749.79--its lowest close since Dec. 1, 2014.

It also marked the index's largest one-day percentage loss since the Chinese government got rid of a "circuit breaker" mechanism on Jan. 8. The system, put into place at the beginning of the year, was blamed for sparking sudden selling instead of achieving the original goal of curtailing volatility.

The Shanghai index is now down 47% from its June peak.

China's Nasdaq-style ChiNext benchmark plunged 7.8%, while the Shenzhen Composite Index closed down 7.1%.

"Pessimism became contagious on the market," said Zhang Xin, an analyst at Guotai Junan Securities. Some investors, he added, had expected the government to support the market once Shanghai reached around 2850. Instead, state-backed funds known as the "National Team"--which have at key pressure points bought shares to prop up the market--were absent on Tuesday, analysts said.

In Hong Kong, the energy sector plunged 5.7%, dragging down the Hang Seng Index by 2.5%. The Hang Seng China Enterprises Index of Chinese firms trading in Hong Kong dropped 3.4% at 7895.16. That benchmark hit a closing low of 7835 last Thursday, and currently trades at its lowest levels since 2009.

The Nikkei Stock Average closed down 2.4%, with Tokyo-listed oil developer Inpex Corp. down 4.3%,

South Korea's Kospi was down 1.2%. Markets in Australia and India are closed for holidays.

The same concerns that have haunted stocks this year remain: Oil prices are trading near multiyear lows, and investors are worried about a slowing China and plans by the U.S. Federal Reserve to raise interest rates. But increasingly, the oil market is driving the action.

"The volatility [in oil] is not helping restore confidence back in the market," said Robert Levine, head of Asian sales and trading at brokerage CLSA. "It's not easy to put on new bets."

Brent crude oil, which widened its losses through the Asia trading day, was last down 2.6% at $29.72 a barrel. It has now fallen more than 20% this year.

But oil's losses haven't helped airlines, which usually benefit from lower costs on oil. China South Airlines Co. Ltd. and Japan Airlines Co. Ltd. slipped a fraction on Tuesday, leaving them down 22% and 2% respectively year-to-date.

Worries about slower global growth are overshadowing the benefits of lower oil, explained Mr. Levine.

No stock exchange in Asia suffered the losses of China, where the CSI 300, a benchmark of blue chip stocks was down 6%. That would have been enough to trigger the old circuit breaker, which kicked in with a 15-minute trading halt if the benchmark fell by 5%, followed by a trading stop for the day if the decline widened to 7%.

"The stress evident today was in the works for a while," given investor worries about capital outflows from China, said Bill Bowler, sales trader at Forsyth Barr Asia Ltd.

Net capital outflows from China have climbed to $550 billion since mid-2015, according to an estimate Tuesday by Goldman Sachs.

Margin loans fell for the 17th straight session to 977.5 billion yuan ($148.5 billion) as of Jan 25, according to Wind Info. These loans, which spurred the market's climb earlier in the year and also exasperated its decline starting in June, peaked at a record 2.27 trillion yuan last year.

Mr. Bowler added that investors are coming to the realization that the government is more reluctant to step in to stop a market plunge. Earlier this week, minutes from the latest meeting by China's central bank showed officials focusing their conversation on maintaining the currency's stability.

"It seemed to imply where the stock market sits on the totem pole," Mr. Bowler said.

Shanghai's fall Tuesday also came as the Chinese yuan was at its weakest level against the U.S. dollar since Jan. 14 in the offshore market, where the currency trades freely. The currency reached 6.62 to one greenback just before the close of Shanghai markets at 3 p.m. local time.

Still, the offshore yuan was roughly unchanged from its levels Monday, and traders said its relative stability in recent sessions has helped bring calm to the domestic stock market.
