HONG KONG, March 12 (Reuters) - Asian shares roared back to life on Wednesday, sparking a 3 percent rally in Japan's Nikkei, after the U.S. Federal Reserve and other central banks teamed up to inject liquidity into strained credit markets.
The U.S. dollar steadied after it rallied on Tuesday from record lows against the euro and near 8-year lows against the Japanese yen.
Oil prices were steady in Asia, having backed off a record high near $110 a barrel the previous day as the dollar rallied, while gold prices continued a retreat from a record high seen last week.
Asian bonds suffered as a rally on Wall Street emboldened investors to turn away from the safe-haven of debt to look again at the riskier-asset class of shares, though the rally in equity markets was accompanied by cautionary notes from analysts.
"The Fed's move will help ease tight credit conditions at financial institutions, but it is not something that solves the real problems," said Yutaka Miura, senior technical analyst at Shinhko Securities in Japan.
Asian stocks have fallen hard this year and the dollar has hit record lows against major currencies on fears the United States is slipping into recession and the global credit crisis could deepen.
The MSCI index of Asian stocks outside Japan <.MIAPJ0000PUS> rose close to 3 percent, bouncing back after hitting a seven-week low on Tuesday.
Japan's Nikkei average <

The rise in Asian stocks came after major central banks, led by the Federal Reserve, teamed up to get hundreds of billions of dollars in fresh funds into cash-starved credit markets. [
]The moves will allow financial firms to use securities backed by mortgages as collateral for central bank loans.
"The Fed's new mortgage put has, like the proverbial butterfly flapping its wings, triggered a strong wind overnight where we see even turkeys flying," wrote Brett Williams, a BNP Paribas credit analyst to clients.
"Appetite for risk roared back from another creative liquidity scheme by the U.S. central bank."
BOJ UNCERTAINTY
The coordinated moves by global central banks did not include the Bank of Japan, which is in the midst of finding a successor to governor Toshihiko Fukui, who retires next week.
Japan's upper house of parliament voted down on Wednesday the government's nominee for that post, Toshiro Muto. [
]The ailing U.S. dollar was steady after sharp gains on Tuesday following the central bank news.
It fell back 0.3 percent to 103.10 yen <JPY=> in Asian trade on Wednesday, but that was well above an 8-year low of 101.40 yen struck on Friday.
The euro barely budged from late U.S. trade at $1.5340 <EUR=>.
Tuesday's surge in the dollar contributed to a decline in oil prices after they hit a record $109.72 a barrel earlier that day.
U.S. crude futures <CLc1> fell in early dealings on Wednesday before swinging to stand up 15 cents at $108.90.
Metals prices were steady following the previous session's falls, with gold <XAU=> trading around $974.40 an ounce, up slightly from around $971.40 in late trade in New York on Tuesday. Gold had hit a record $991.90 on March 6.
