Asian stock markets rallied Thursday, led by a 12 percent jump in South Korea, after the U.S. Federal Reserve slashed interest rates to help revive the world's largest economy and opened new credit lines with central banks.
Every major index advanced, with Japan's Nikkei 225 stock average gaining 10 percent percent to 9,029.76 as exporters like Toyota and Sony got a boost from the yen continuing to retreat from a 13-year high against the dollar last week.
Hong Kong's Hang Seng Index shot up 9.3 percent to 13,882.60, and South Korea's key stock index soared a record 12 percent to 1,084.72. Benchmarks in Australia, Singapore, Taiwan and the Philippines added 4 percent or more. Russia's two main indices were also up sharply.
Wall Street futures suggested U.S. markets were poised to open higher. Dow Jones industrial average futures were up nearly 4 percent at 9,200.
The Federal Reserve's overnight move to cut its key interest rate by half a percentage point was widely expected but still provided a reason to sustain the regional rise that began Tuesday following days of punishing declines.
Hong Kong's de facto central bank followed by cutting its key lending by the same amount as the Fed and Taiwan reduced its key interest rate by a quarter point. In Japan, speculation mounted that the central bank would cut its key rate, already at a low 0.5 percent, at a meeting Friday.
Before the Fed acted, China also lowered its rates by just over a quarter point. The Shanghai Composite index was up 2.9 percent.
Markets also took heart from an announcement that the Fed would temporarily supply new lines of credit worth up to $30 billion to the central banks of South Korea, Brazil, Mexico and Singapore to help relieve the global credit crisis.
"This does help investor confidence," said Lorraine Tan, director at Standard & Poor's equity research in Singapore. "Globally, governments are just doing what they can to make sure the economy doesn't seem even worse ... Plus I think investors are waking up to the fact that valuations are ridiculously low."
The $30 billion facility is the latest in a series of swap arrangements where the Fed provides dollars for reserves of the other nations' currencies.
The Fed said the new credit lines were designed "to help improve liquidity conditions in global financial markets" by increasing the global availability of U.S. dollars. The move appeared to help loosen lending among the region's banks. Hong Kong's interbank offered rate, also known as Hibor, for three-month loans slid to 3.39 percent from 3.54 percent.
Oil prices continued to strengthen. Light, sweet crude for December delivery climbed another $2.22 to $69.72 a barrel in Asian trade on the New York Mercantile Exchange. The contract rose $4.77 to settle at $67.50 overnight.
In currencies, the dollar rose to 98.78 yen from 97.59 late New York Wednesday and up sharply from 91 yen last Friday.
Investors in Asia shrug off Wall Street's mixed finish. The Dow Jones industrial average closed down 74.16, or 0.82 percent, at 8,990.96. The S&P 500 index fell 10.42, or 1.11 percent, to 930.09, but the Nasdaq closed higher.
Japan's Sony Corp. rose 11.6 percent, even after the company reported late Wednesday that its net profit for the July-September quarter plunged 72 percent. Toyota Motor Corp. jumped 11.4 percent.
South Korea's battered financials powered higher after the Fed's moves. KB Financial Group Inc., the holding company for top South Korean lender Kookmin Bank, soared 9.4 percent.
In Australia, resource giant BHP Billiton Ltd. gained 8.8 percent on the back of rising commodities prices. Chinese upstream oil producer CNOOC Ltd. rocketed 17.7 percent.
Markets in India were closed for a public holiday.
