TOKYO, Sept 10 (Reuters) - The yen hovered near a 13-month high against the euro on Wednesday and kept a firm tone against many currencies on risk aversion, as concerns over the health of Lehman Brothers <LEH.N> renewed doubts about the U.S. financial sector.
The yen received a broad lift in early Asian trade after shares in U.S. investment bank Lehman Brothers posted their biggest one-day decline on record on Tuesday, causing investors to dump risky carry trades funded by the low-yielding yen.
While short-term players sold the yen to book profits in early trade, concerns over the bank's ability to raise capital provided support.
The euro rose 0.3 percent from late New York trade to 151.76 yen <EURJPY=R>. Moves were volatile with the single currency jumping as high as 151.93 on trading platform EBS from an earlier trough of 150.51 yen, a new 13-month low.
Lehman, the fourth-largest Wall Street investment bank, will unveil strategic initiatives and announce third-quarter results later in the day, a week earlier than initially scheduled. [

Oil prices jumped on Wednesday, reversing early losses after OPEC unexpectedly agreed to effectively cut production despite market expectations that current production targets would be maintained.[
]The decision dented the the dollar against the euro and the Australian dollar, but the impact was limited as concerns about a global economic slowdown kept a lid on European and commodities-related currencies, traders said.
"The euro and the Australian dollar are likely to continue recent broad slides with investors rushing to liquidate positions and repatriate to the dollar, amid a souring global growth outlook," said Shuichi Kanehira, a senior trader at Mizuho Corporate Bank.
The dollar rose 0.4 percent to 107.20 yen <JPY=>, getting a lift from the euro's rebound versus the yen.
Against the dollar, the euro was up 0.1 percent at $1.4153 <EUR=>, staying above an 11-month low of $1.4046 hit the previous day.
The dollar index <.DXY>, which measures the greenback's value against six major currencies, dipped 0.2 percent to 79.267, below a one-year peak of 79.844 hit on Monday, according to Reuters data.
The Australian dollar rose 0.7 percent to $0.8068 <AUD=D4>, recovering from an earlier low below $0.80, its lowest level since August 2007, lifted by rebounding oil and gold prices.
Against the yen, the Aussie jumped 1.1 percent to 86.48 yen <AUDJPY=R>.
On Tuesday, oil prices fell to a five-month low below $102 a barrel, about 30 percent below the all-time high of $147.27 hit in July. (Additional reporting by Shinichi Saoshiro; Editing by Chris Gallagher)
