HONG KONG/SINGAPORE, Sept 10 (Reuters) - Asian stocks fell about 1 percent and U.S. Treasuries dipped on Wednesday on fears about Lehman Brothers' ability to raise capital, demonstrating Washington's bailout of Fannie Mae and Freddie Mac this week had not fixed the credit crisis.
Oil prices rose toward $104 a barrel, reversing earlier losses, after OPEC agreed to return to its 2007 production target, an effective cut in output. But crude remains close to $100, below which Goldman Sachs said earlier this week could signal a global recession.
A retreat in oil prices from a record high in July has supported the U.S. dollar, which hit an 13-month high against the euro <EUR=> on Tuesday.
While the U.S. government bailout of its top mortgage finance companies on Sunday removed a big risk of a system-wide failure, problems at other financial institutions were painful reminders of how severely an avalanche of bad loans has threatened almost every major economy.
Shares of firms such as Macquarie Group Ltd <MQG.AX>, Australia's largest investment bank, and Mizuho Financial Group <8411.T>, Japan's second-largest lender, sank after Lehman stock <LEH.N> plunged 45 percent overnight on fears it would not be able to raise the funds it needs to survive.
Lehman reports its quarterly results ahead of the U.S. stock market open.
"Today's fall is a Lehman shock," said Yoku Ihara, manager of the investment information department at Retela Crea Securities. "We thought the market would rebound after the Freddie and Fannie news, but Lehman rekindled worries."
The Wall Street Journal reported Lehman was in talks with investment firm Blackrock Inc <BLK.N> to sell a package of British residential real estate assets and was looking at spinning off some commercial property assets. [

Japanese bonds initially gained, but the September 10-year JGB futures soon was trading nearly flat at 136.94 <2JGBv1>.
The euro was also listless ahead of the Lehman results, trading nearly steady at $1.4130 <EUR=>, nearly 20 cents lower than where it was in mid-July when crude prices peaked.
The dollar gained ground against the yen, rising 0.3 percent to 107.25 yen <JPY=>, largely as dealers covered their short-term bets on the Japanese currency.
DOLLAR BEARS
A combination of falling commodity prices, a desire to avoid risk taking and signs of economic gloom spreading to Europe and Japan have all pushed the dollar higher for the last two months.
However, some fund managers are holding fast to their long-term negative view on the U.S. currency. Even the excitement over the Fannie and Freddie bailout seemed to have all but evaporated.
"The bail-out honeymoon already appears to be over. Risk aversion was back with a vengeance...," Rabobank said in a note to clients.
V. Anantha Nageswaran, a strategist with Julius Baer, said the bailout and the rally it spurred in risk assets were like "comic interludes" in a long-drawn deleveraging process.
"A new risk cropped up and they addressed that new risk. That doesn't mean the underlying risk went away, which is that the shrinking of household and financial sector balance sheets is a multi-year process," Nageswaran said.
While gauges of investors' distaste for risk taking have fallen from mid-July highs, they have risen steadily so far in September. The so-called TED spread of 3-month borrowing rates among large banks over the 3-month U.S. Treasury bill yield widened to the most since July 23 on Wednesday.
The October U.S. light crude future was up around $1 to $104.20 a barrel <CLc1>, after earlier tumbling to near $102.
OPEC formally agreed to return to its 2007 production target of 28.8 million barrels per day.
The oil cartel had been widely expected to maintain current production targets at its meeting in Vienna, although some ministers had advocated tighter compliance with formal limits by members who were overproducing their targets.
