HONG KONG, Feb 29 (Reuters) - The dollar dropped to a 3-year low against the yen on Friday amid renewed worries about the U.S. economy, rattling stock markets, bolstering bonds and helping drive up prices of safe-haven gold and oil to all-time highs.
Weak U.S. economic data and a warning from Federal Reserve Chairman Ben Bernanke that some small U.S. banks could fail raised expectations for more interest rate cuts in the world's leading economy.
The dollar <JPY=> tumbled to 104.65 yen, its lowest since May 2005, after a slide in the U.S. currency towards the key 105 yen level triggered a wave of stop-loss orders.
Gold <XAU=> surged to a new high of $973.10 an ounce, up more than 16 percent this year, and crude oil <CLc1> hit $103 a barrel for the first time in history, fuelled by the weak dollar and a fire at a big European gas terminal. [
]By 0230 GMT, spot gold stood at $969.40 an ounce and oil was quoted at $102.60 a barrel.
MSCI's index of Asian stocks outside Japan <.MIAPJ0000PUS> was down 1.5 percent by 0220 GMT, while Japan's benchmark Nikkei average <
> and the broader TOPIX < > were off 2.5 percent as investors digested Bernanke's ugly prognosis."This will have an impact in terms of credit worries but, even more, it reflects growing concern about the worsening U.S. economy," said Yutaka Miura, senior technical analyst at Shinko Securities. "But for Tokyo, the real worry is the yen's rise against the dollar, which is going to make things really tough."
The sour mood in the stock market was a sweetener for Japanese government debt as investors sought shelter from the U.S. storm.
"Bernanke's remarks were something a central banker should never say," said a bond strategist at a U.S. brokerage. "It shocked us and certainly worsened credit jitters in the market."
March 10-year Japanese government bond futures <2JGBv1> rose as high as 138.42, their highest since Jan. 24, while the benchmark 10-year yield <JP10YTN=JBTC>, which touched a 2-month peak of 1.500 percent earlier this week, tumbled to a 5-week low of 1.365 percent.
STOCKS SHOCKED
Among the hardest-hit stocks were tech firms and insurers, troubled by a lower-than-expected profit at computer maker Dell Inc <DELL.O> [
] and a large quarterly loss at American International Group Inc <AIG.N>, the world's largest insurer, on write-downs of derivatives related to bad mortgage investments. [ ]The continuing commodities rally cheered some firms in the sector, such as Korea Zinc <010130.KS>, which was one of the top gainers in Seoul <.PG.KS>, rising 7.7 percent after London zinc futures <MZN3> jumped 5 percent on Thursday.
Overall, the main South Korean index <
> was down 1.4 percent. Hong Kong's Hang Seng index < > fell 1.8 percent, with global lender HSBC Holdings <0005.HK> leading the blue chips lower with a 2 percent slide.The commodities boom was not enough to stop the mining-heavy Australian index <
> losing 2.3 percent as fear of higher interest rates to tame inflation continued to trouble banks.And although it reported a 58 percent jump in profits, Air New Zealand Ltd <AIR.NZ> fell 6.8 percent as rising fuel prices and currency difficulties pummelled airline shares.
