LONDON, May 27 (Reuters) - Oil prices rose to a six-month high above $63 a barrel on Wednesday after Saudi Arabia, OPEC's biggest member, said the global economy had strengthened enough to cope with oil at $75-$80 a barrel.
Ahead of a meeting of the Organization of Petroleum Exporting Countries in Vienna Thursday, Saudi Oil Minister Ali al-Naimi said oil prices would continue to rise, recovering from lows near $32 at the turn of the year.
"The price rise is a function of optimism, better things are coming in the future," Naimi told reporters in Vienna.
The minister said OPEC did not need to change its output policy, which has already seen the group agree to remove 4.2 million barrels per day of oil from the market in a bid to shore up prices battered by recession.
U.S. crude oil for July delivery <CLc1> rose to touch $63.45 a barrel, the highest level since mid-November, before easing back to trade up 16 cents at $62.61 a barrel by 1445 GMT. London Brent crude <LCOc1> rose 32 cents to $61.56 a barrel.
Bolstering the market, U.S. housing data showed the pace of sales of existing homes in the United States rose 2.9 percent in April, supporting views that the three-year housing recession was near a bottom.
But weakness in the U.S. stock market tempered oil's strength. Wall Street shares declined amid gloom around General Motors as it inched closer to bankruptcy, and strength in the U.S. dollar against the euro, dealers said.
"We're not really seeing a strong recovery yet, but I think OPEC are implying they don't see oil demand falling any further," VTB Capital analyst Andrey Kryuchenkov said.
"Everyone talks about green shoots but we're not completely out of the woods -- to see a real price rally we'll need to see a larger pick-up in demand."
Global oil demand is seen falling this year at the fastest rate since 1981, with the International Energy Agency, adviser to 28 industrialised nations, predicting a decline of 2.56 million barrels per day.
Crude inventories have risen to around 62 days of forward cover, but expectations of a slight drawdown in U.S. crude inventories are supporting prices, analysts said.
A preliminary Reuters poll ahead of U.S. weekly inventory data showed an average forecast of a 1.1 million drawdown in crude stocks and a 1.8 million decline in gasoline stocks last week.
Data from the American Petroleum Institute has been delayed by one day until Wednesday while U.S. Energy Information Administration oil inventory data will be released Thursday due to the U.S. Memorial Day holiday at the start of this week.
Prices also shot above the key technical level of the 200-day moving average for the first time in more than eight months, adding to some analysts' convictions that oil has found a new price floor at $60 and may rise toward $65.
