LONDON, Sept 16 (Reuters) - Oil fell 3 percent on Tuesday on rising concern that turmoil in global financial markets will further undermine fuel demand and send investors into safer havens. Reports that U.S. oil infrastructure had escaped major damage from Hurricane Ike also weighed on markets, which fell more than $5 on Monday after Lehman Brothers <LEH.N> sought bankruptcy protection. [
]U.S. crude <CLc1> for October traded down $2.66 to $93.05 a barrel by 1501 GMT, off a seven-month low of $90.55 a barrel earlier in the session.
November Brent crude <LCOc1> fell $2.97 to $91.27 a barrel.
"If the economic turmoil continues, demand will continue to drop," said Jonathan Kornafel, Asia Director at U.S.-based options trader Hudson Capital Energy. "It's a bit of panic in the markets."
Slowing demand in the United States and other top consumer nations has sent crude prices tumbling from record highs over $147 a barrel in July.
"We have gotten into what appears to be the final stages of liquidations by long investors that thought they were buying for an up move that was going to last for a number of years," Peter Beutel, president of Cameron Hanover in New Canaan, Connecticut.
Monday marked the worst day on Wall Street since markets reopened after the Sept. 11 attacks, with investors fleeing to safer havens such as gold after the news on Lehman and the sale of Merrill Lynch <MER.N>.
Growing problems at insurer American International Group <AIG.N> added to fears about the financial sector's stability and the outlook for the global economy.
"If AIG tanks, that will be the big one. AIG has more to do with the oil price right now than the Saudis do," said Larry Grace, an analyst at Kim Eng Securities in Hong Kong.
European shares fell on Tuesday amid concerns over AIG, driving up the yen and government bonds.
Federal Reserve policy-makers are expected to stop short of lowering U.S. interest rates at a meeting on Tuesday but could signal readiness to cut them quickly if needed to protect the economy from one of the most serious financial crises in decades. [
]IKE REBOUND
Further pressure on prices came on expectations a large part of U.S. energy production shut by Hurricane Ike would restart within a week as reports showed the storm caused only minor damage to oil platforms and refineries. [
]Fuel supply disruptions are still possible in the meantime, as the shutdowns cut already threadbare gasoline inventories to their lowest levels on record, sending pump prices spiking.
The oil price fell despite renewed concern about supply in Nigeria, where militants attacked a Royal Dutch Shell <RDSa.L> oil pipeline and Chevron-operated <CVX.N> oilfield, militants and security sources said on Tuesday.
