NEW YORK, Sept 17 (Reuters) - Oil prices shot up $6 on Wednesday, the largest one-day percentage gain in three months, as a U.S. government report showed nationwide energy inventories fell in the aftermath of the Gulf Coast hurricanes and the greenback slid against the euro.
The gains followed the steepest two-day sell-off in the oil market in four years which came as mounting economic turmoil in the United States sent investors fleeing to safer havens like bonds and gold.
"Crude oil prices have rebounded, having fallen sharply to near $90. At that level, I think the bear market near-term correction has run its course. Prices are also up on low petroleum inventories and on the prospect that they may even go lower in coming weeks," said Tom Knight, a trader at Truman Arnold in Texarkana, Texas.
U.S. crude oil prices <CLc1> settled at $97.16 a barrel, up $6.01, while London Brent crude oil <LCOc1> settled at $94.84 a barrel, up $5.62.
The gains came after the U.S. Energy Information Administration reported a larger-than-expected decline in domestic crude oil inventories of 6.3 million barrels as hurricanes Gustav and Ike slashed production and imports. [
]The EIA report also showed U.S. gasoline inventories fell last week to their lowest level on record as refinery production took a hit from the storms.
Oil companies were working to restore operations in the Gulf of Mexico and along the Gulf Coast after the latest hurricane, Ike, slammed into Texas last Saturday and shut down a quarter of the nation's energy output.
As of Wednesday morning, more than 97 percent of the Gulf of Mexico's oil production was still shut and a dozen refineries along the coast, representing a fifth of U.S. fuel production, remained off line. [
]Oil received additional support when the euro rose to a session high against the dollar after breaking a key technical level, forcing investors who had bet against the single zone currency to buy euros to prevent further losses. [
]Traders were keeping a close eye on financial markets, however, as U.S. stocks slid due to a spike in interbank lending rates and on concerns the U.S. government rescue of insurer American International Group <AIG.N> would not stem the turmoil that has rocked markets this week. [
]"We expect markets to remain volatile for at least the next few days until people start to refocus on oil market fundamentals," said Helen Henton, head of commodities for Standard Charter in London.
Oil prices are down more than third since peaks above $147 a barrel in mid-July as high energy costs and economic woes cut deeply into fuel demand.
Fresh attacks on Nigerian oil installations also provided some support to the market Wednesday. [
