* Deleveraging helps US dollar, hurts stocks and commodities
* Lehman's losses keep focus on unstable financial sector
* MSCI Asia-ex Japan index at lowest since October 2006

HONG KONG, Sept 11 (Reuters) - The U.S. dollar rose to a one-year high against the euro on Thursday, pushed up by overnight losses in crude oil and as heightened market volatility convinced U.S. investors to bring overseas money back home.
Asian stocks fell broadly, with Tokyo's Nikkei share average <
> retreating 1.3 percent to a six-month low and the MSCI Asia Pacific ex-Japan index <.MIAPJ0000PUS> down 1.1 percent to its lowest since October 2006.Bank stocks suffered bigger losses after U.S. investment bank Lehman Brothers <LEH.N> posted a record quarterly loss of $3.9 billion. The dismal results from Lehman, which is trying to shed assets to stay alive, sent a message to investors that the year-long global credit crisis will likely claim more victims before ending. [
]Indications of increased volatility in stock and bond markets as well as economic deterioration in just about every part of the world has led investors to cut back on overseas risk in their portfolios, supporting the dollar.
"The market's direction points toward dollar buying," said Hideaki Inoue, chief manager of forex trading at Mitsubishi UFJ Trust Bank in Tokyo.
"What we are witnessing now is position adjustments that are part of a bigger picture, one in which investors are pulling back money from risk assets," Inoue said.
The euro briefly fell below $1.3950 <EUR=> to the lowest since September 2007, with investors focused for now on rapidly slowing economic growth outside of the United States.
However, the dollar fell against the yen, down 0.3 percent to 107.47 yen <JPY=>. Against the yen, the euro tumbled 0.5 percent to 149.90 yen <EURJPY=>.
The dollar for the most part has been rallying since crude oil prices peaked at $147.27 a barrel in mid July and then fell sharply.
The U.S. currency received an added boost by the U.S. government's takeover of Fannie Mae <FNM.N> and Freddie Mac <FRE.N> at the weekend, which helped calm some fears of further widespread bond market losses.
Still, worries about troubles at other financial institutions continued to dog bank stocks. Shares of Mitsubishi UFJ Financial Group <8306.T> fell 4 percent and Industrial and Commercial Bank of China <1398.HK>, the biggest-earning bank globally, was off 1 percent.
In Australia, the benchmark S&P/ASX 200 <
> index fell 1.3 percent, led by shares of some of the country's top banks, such as National Australia Bank <NAB.AX> and Commonwealth Bank of Australia <CBA.AX>.Hong Kong's Hang Seng index <
> declined 0.8 percent, down for a third day and heading toward a one-year low touched on Friday.The regional weakness put the MSCI all-country world index <.MIWD00000PUS> on course for the ninth down day of the last 10. The index hit a two-year low on Wednesday.
The October U.S. light crude contract <CLc1> edged up 78 cents to $103.36 <CLc1> after hitting a five-month low on Wednesday as the dollar rallied. Crude would need to trade above $109 a barrel to break a steep downward trend in prices that has held since July 14. [
]The widespread liquidation of commodity-related trades also hit the gold market as risk taking took a back seat to the need for stability.
Gold <XAU=> briefly dropped to the lowest since October 2007 in the spot market of $748.60 an ounce after the dollar rallied to a 1-year high against the euro, but bounced to $754.10 an ounce.
"Investor interest has diminished because of the movement of the U.S. dollar and the oil price," said David Moore, analyst at Commonwealth Bank of Australia in Sydney.
The reduction in risk taking in just about every asset class has been swift and definite and has been pushing up the cost of insurance against credit defaults.
"We have entered a new phase of the credit cycle marked by accelerated deleveraging. Herd recycling of risk through commodities, currencies, rates, and equities is sponsoring hyper volatility," said Brett Williams, credit analyst with BNP Paribas in Hong Kong.
