 LONDON, Oct 13 (Reuters) - Oil rose more than $3 a barrel on
Monday, after governments around the world acted to boost
confidence in the global financial system, prompting a rally in
European and Asian stock markets and a rebound in commodities.
                                
 But investment bank Goldman Sachs said the financial crisis
had already done more damage than it expected to commodity
demand and warned that a slide to $50 a barrel for oil could be
possible. [ID:nSP377875]
                                
 U.S crude <CLc1> for November delivery was up $3.48 at
$81.18 a barrel by 1019 GMT.
                                
 Prices had plunged on Friday to their lowest since Sept. 10,
2007. London Brent crude <LCOc1> was up $3.23 at $77.32 a
barrel.
                                
 "The announcements from over the weekend would have some
positive effects on the markets, even though it's still in very
early days at this stage to say if they would put an end to the
financial crisis," said David Moore, a commodities analyst at
the Commonwealth Bank of Australia.
                                
 Goldman Sachs, once a longstanding commodity bull, turned a
near-term bear on Monday after conceding that global financial
turmoil would take a far bigger toll on demand. It warned that
$50 oil was possible if the crisis deepened.
                                
 "We have underestimated the depth and duration of the global
financial crisis and its implications on economic growth and
commodity demand," its commodity markets research team said.
                                
 The bank cut its year-end U.S. crude oil target to $70 a
barrel, down from a previous forecast of $115 a barrel, and
slashed its average 2009 forecast by a third to $86 a barrel.
                                
 A fall in demand in the United States and other developed
economies has helped drive oil down nearly 50 percent from its
July peak of above $147 a barrel.
                                
 A boom in consumption from emerging markets such as China
had contributed to a six-year rally in commodity prices.
                                
 Oil's fall has caused some members of the Organization of
the Petroleum Exporting Countries to call for a cut in
production levels. The producer group has agreed to hold an
emergency meeting in Vienna on Nov. 18 to discuss the impact of
the global financial crisis on the oil market.
                                
 Iran is set to push for a cut in oil output at the meeting,
its oil minister said in comments published on Sunday, adding
investment conditions in the oil industry would be severely hit
unless OPEC acted decisively to arrest the current fall in oil
prices. [ID:nLC694953]
                                
 Saudi Arabia, the world's biggest exporter and OPEC's most
influential member, has cut November supplies to one major
European refiner, according to a trade source. But the kingdom
told major Asian refiners that it would maintain crude oil
shipments unchanged. [ID:nSP349848]
