* Euro zone leaders agree to bank support measures

PERTH, Oct 13 (Reuters) - Oil jumped more than $3 on Monday, recouping part of Friday's 10 percent dive as European leaders took bolder steps to pull the banking sector out of crisis.
Countries from Europe to Australia rushed out plans on Sunday to shore up their banks, trying to stem a crash in markets, while investment bank Goldman Sachs said the financial crisis had already done more damage than it expected to commodity demand, forcing it to dramatically cut price targets.
U.S crude <CLc1> for November delivery rose $2.68 to $80.38 a barrel by 0300 GMT, earlier climbing above $81 a barrel in a bounce-back from Friday's nearly $9 plunge to its lowest level since Sept. 10, 2007.
London Brent crude <LCOc1> rose $2.18 to $76.27 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.
In Europe, government leaders agreed on commitments to provide capital for banks caught short of funds because of frozen money markets and to insure or buy into new debt issues, the latest in a series of bold measures. [

]The news lifted U.S. stock futures on Sunday evening after they had plunged more than 18 percent last week in their worst-ever weekly fall as panicked investors dumped stocks on fears the economy was headed irreversibly into recession.
Slumping demand in the United States and other developed economies have sent oil prices off their July peak of above $147 a barrel, reached after surging consumption in emerging markets such as China sent commodities on a six-year rally.
GOLDMAN TURNS NEAR-TERM BEAR
Goldman Sachs, once one of the foremost bulls on commodities, turned a near-term bear on Monday after conceding that global financial turmoil would take a far bigger toll on demand, warning 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.
The price fall has caused some OPEC members to call for a cut in production levels, and the cartel 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 an OPEC emergency meeting in November, 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. [
