TOKYO — Asian stocks were mixed Wednesday and Shanghai's index fell despite Beijing's decision to cut a key interest rate to help stabilize gyrating financial markets and counter short liquidity.
The benchmark Shanghai Composite Index fell late in the day after spending most of the afternoon in positive territory. It closed down 1.3 percent at 2,927.29 on heavy selling of steelmakers and other heavy industrials.
Most other Asian markets initially wavered but had appeared to regain buying momentum by early afternoon. Japan's main Nikkei 225 stock index advanced 3.2 percent to 18,376.83, and South Korea's Kospi gained 2.6 percent to 1,894.09.
But Hong Kong's Hang Seng index fell 0.5 percent to 21,305.17, and mainland China's smaller Shenzhen Composite Index lost 3.1 percent.
Elsewhere in Asia, Australian shares gained 0.7 percent to 5,172.80, helped by buying of resource-related shares. Shares also rose in Taiwan but fell in New Zealand and most Southeast Asian markets.
Many in Asia went to bed Tuesday smiling over China's decision to slash its key interest rate, only to awaken to yet another decline overnight on Wall Street, Nicholas Teo, an analyst at CMC Markets, said in a commentary.
"All of a sudden, China and the performance of the Chinese markets have now taken the lead in determining daily direction for trading in stocks worldwide," he said. Meanwhile, investors unable to meet margin calls are being forced to sell, regardless of the Chinese central bank's decision.
"With confidence in the markets completely shattered, the likelihood of buyers meeting these intermittent bouts of forced selling may just be few and far in-between," he said.
Markets have been zigzagging for weeks on deepening unease over the ramifications of slowing growth in China, the world's second-largest economy and the driver of much of the global growth of the past decade.
The apparent inability of Chinese regulators to stabilize the markets, has spooked investors already fretting over when the U.S. Federal Reserve will raise interest rates.
Asia got a slow start following a last-minute sell-off that dragged the Dow Jones industrial average down 204.91 points, or 1.3 percent, on Tuesday to 15,666.44. That extended Wall Street's losing streak to six days, the longest such stretch in more than three years.
The Dow had surged more than 400 points after China cut its interest rates for the fifth time in nine months in a renewed effort to shore up growth. The central bank also increased the amount of money available for lending by reducing the reserves banks are required to hold.
The People's Bank of China acted after the Shanghai stock index slumped 7.6 percent on Tuesday, on top of an 8.5 percent loss on Monday.
In other trading, U.S. crude oil rose 1 cent to $39.32 a barrel in electronic trading on the New York Mercantile Exchange. It rose $1.07, or 2.8 percent, to $39.31 on Tuesday. Brent crude oil, which is used to price international trading, gained 6 cents a barrel, to $43.15.
The dollar rose to 119.35 yen versus 118.66 yen late Wednesday. The euro slipped to $1.1509 from $1.1524.
