PERTH, Nov 3 (Reuters) - Oil rose above $68 a barrel on Monday, reversing earlier losses of over $1, as Asian stock markets climbed on signs of improvement in credit markets, buoying investor confidence.
Analysts said traders would now be looking for signs that OPEC kingpin Saudi Arabia was cutting back its crude production in line with the cartel's agreement last month to reduce output by 1.5 million barrels per day (bpd).
U.S. crude <CLc1> rose 44 cents to $68.25 a barrel by 0139 GMT, after falling as much as $1.13. London Brent crude <LCOc1> was down 43 cents at $65.75.
"We're now seeing a more positive tide in stock markets, which is a good indication for crude oil markets and that's helping to stop the downward momentum in oil prices," said Toby Hassall, chief analyst at Commodities Warrants Australia.
"But the dominating theme continues to be a weak demand outlook, and despite the short term price gains, we're not likely to see any real improvement to outlook in the near term."
Asian stocks rose on Monday, after Wall Street ended a turbulent October on a solid note.
Singapore's Straits Times Index <.FTSTI> rose over 4 percent in early trade, Australia's S&P/ASX 200 Index was up 2.6 percent, while South Korea's shares were steady after paring earlier gains up to 4 percent.
U.S. oil fell more than 32 percent in October, the steepest monthly decline ever as global demand slows.
In three months, oil has wiped out gains that took more than a year to build, down more than half since they struck a record $147.27 a barrel in July as a raft of poor economic data added pressure from weak demand reports in the U.S. and other key consumer nations.
OPEC members have no choice but to implement agreed output cuts and inform customers of the reductions if they want a stable oil price between $70-$90 a barrel, OPEC President Chakib Khelil said on Sunday.
Khelil said Saudi Arabia was the key to the success of the reductions, and if the world's biggest oil exporter took its time over the operation the oil price could be affected. [
]Other OPEC members have begun to notify customers that they would reduce their crude oil sales in line with an OPEC decision to cut output.
Iran's oil minister said on Saturday it had informed customer France's Total <TOTF.PA> of an oil sales cut [
], while Kuwait has notified term customers in Asia it would reduce their crude oil supplies by 5 percent from November. [ ]Earlier last week, Nigeria and the United Arab Emirates told customers they would receive less oil, but top exporter Saudi Arabia has yet to inform customers of any fresh curbs.
Oil's sharp downturn has spurred some OPEC members to call for additional supply reductions to arrest a continued slide in oil prices.
Iran's Oil Minister Gholamhossein Nozari said on Saturday that OPEC will cut output further, if needed, to achieve stability in the oil market [
], adding to comments by Venezuelan oil minister last week that OPEC should cut oil output by another 1 million bpd by December and should set a minimum price target of $70 or $80 a barrel.Crude oil speculators on the New York Mercantile Exchange shifted to net short positions in the week Oct. 28, the U.S. Commodity Futures Trading Commissions reported on Friday.
