(Adds European outlook, updates prices)
By Tom Miles
HONG KONG, Feb 13 (Reuters) - Asian equity markets wavered on Wednesday after an early surge, fuelled by billionaire investor Warren Buffett's offer to take on $800 billion of U.S. municipal bond risk, petered out and U.S. economic worries resurfaced.
Buffett's plan eased fears for the health of the insurance sector and lifted Asian equities in early trade, although they later slipped back. [
]European stocks are set to open about 1 percent lower, with earnings from bid target Rio Tinto <RIO.L>, steel major Arcelor Mittal <MTP.PA> and oil group Total <TOTF.PA> to chew over.
Japan's Nikkei average <

Major banks such as Mitsubishi UFJ Financial Group <8306.T> fell, offsetting gains in exporters such as Canon Inc <7751.T>.MSCI's index of Asian stocks outside Japan <.MIAPJ0000PUS> was down 0.2 percent by 0655 GMT, while Shanghai stocks <

BANKS BATTERED
Banks also battered Australia's S&P/ASX 200 index <

"We're seeing markets responding to what the Reserve Bank is saying and the need to slow activity. That has implications for the credit cycle," said Karara Capital investment manager Rohan Walsh.

U.S. Treasuries [
] barely moved in Asia, keeping the yield on two-year bonds near a four-year low. With markets sensitive to any sign of a slowdown in the U.S. economy, traders set their sights on U.S. retail sales data due at 1330 GMT."The market is expecting a weak reading, it's just a matter of how much weakness is already factored in," said a dealer at a Japanese trust bank.
"If a disappointing number does not trigger selling in stocks, we would see some downward pressure on Treasuries."
Also due is a reading on the U.S. trade deficit, which is projected to narrow moderately to $61.5 billion in December, from $63.12 billion in November.
The data will set the scene for testimony on Thursday from U.S. Federal Reserve Chairman Ben Bernanke, following a quarterly survey from the Philadelphia Federal Reserve on Tuesday, which said the economy would struggle to grow in the first quarter of this year. [

"Basically, the market's worries have been just temporarily lifted," said Takashi Ushio, head of the investment strategy division at Marusan Securities in Tokyo. "This doesn't address the root cause of the crisis. The only thing that will really solve the situation is measures like a fund injection."
Buffet's move also sapped enthusiasm for safe-haven assets such as gold <XAU=>, which slipped back towards $900 an ounce. The metal was also tarnished by a top industry official in India saying high prices were killing off demand. [
]Treasury dealers said Buffett's plan, which would cover bonds at the quality end of the market, may do little to mitigate the risks of further fallout from the subprime crisis.
