NEW YORK, April 12 (Reuters) - Crude fell sharply on Tuesday as Goldman Sachs warned again of a price reversal, while the International Energy Agency and OPEC said expensive oil could erode demand.
Oil extended its retreat from 32-month peaks reached on Monday and U.S. crude looked set to post the biggest two-day percentage loss since May 2010, when the Greek and wider euro zone debt crises pressured commodities.
Saudi Arabia, pointing to lackluster demand, reversed a recent output hike that had been expected to make up for production shut down by Libya's conflict, also weighing on crude prices.
OPEC kept its 2011 oil demand forecast steady, but said the group saw a risk that higher oil prices could dent demand for transport fuel. [
]A slightly higher demand growth forecast for 2011 came from the U.S. Energy Information Administration, although the agency lowered its forecast of 2012 demand growth. [
]Brent crude for May <LCOc1> fell $3.10 to $120.88 a barrel by 12:47 p.m. EDT (1647 GMT).
U.S. crude <CLc1> lost $3.85 to $106.07.
Investors that bought into the oil market in the past few months could now be making a move to exit, according to Brendan Brown, head of economic research at Mitsubishi UFJ Securities.
"I think we are going to see some sort of a rotation, with some investors deciding to get out and take some profit," Brown told Reuters.
That seemed to be Goldman Sachs' <GS.N> message for the second straight day.
Goldman expects Brent to fall toward $105 in coming months, it said in a note emailed to clients on Tuesday. A day earlier, the bank recommended closing its 'CCCP Basket' trade, which includes a 40 percent weighting in U.S. crude futures. [

]DEMAND CONCERNS
Sources told Reuters that Saudi Arabia, holder of the most spare production capacity in the Organization of the Petroleum Exporting Countries, had trimmed production by around 500,000 barrels per day to around 8.5 million bpd due to slow demand. [
]Saudi Arabia's production cut comes amid increasing concerns about lofty oil prices.
High prices are beginning to dent growth in oil demand, Western consuming nations' energy policy adviser the IEA said on Tuesday. [
]The IEA said few expect OPEC to agree formally to raise output and that could mean prices will correct and fall back because of a global economic slowdown. [
]"Fear of demand destruction is killing this market. There is a feeling that the recent rally lifted oil prices to unsustainable levels," said Phil Flynn, analyst at PFGBest Research in Chicago.
Japanese demand remains in question as economic damage from last month's earthquake and tsunami is likely to be worse than first thought, the country's economics minister warned. [
]SUPPLY THREATS
Uncertainty remained over Libya's conflict and the Middle East, where protests and opposition to current regimes continued.
France and Britain urged NATO to do more to stop Muammar Gaddafi's forces from bombarding civilians as clashes continued in Libya. [
