Oil prices eased on Friday, heading for a third consecutive monthly decline, as a stronger US dollar and weak China data capped gains while rising supply from major producers globally offset the impact of Western sanctions on Russian exports.
Brent crude futures slipped 12 cents, or 0.18%, to $64.88 a barrel by 0744 GMT, while US West Texas Intermediate crude was at $60.36 a barrel, down 21 cents, or 0.35%.
"A stronger USD weighed on investor appetite across the commodities complex," ANZ analysts said in a client note.
The greenback was boosted after US Federal Reserve Chair Jerome Powell said on Wednesday an interest rate cut in December was not guaranteed, Reuters said.
Oil also slipped after an official survey showed China's factory activity shrank for a seventh month in October.
Both Brent and WTI are set to fall about 3% in October as rising supply is set to exceed demand growth this year, with the Organization of the Petroleum Exporting Countries and major non-OPEC producers ramping up output to gain market share.
More supply will also cushion the impact of Western sanctions disrupting Russian oil exports to its top buyers China and India.
OPEC+ is leaning towards a modest output boost in December, people familiar with the talks said ahead of the group's meeting on Sunday.
The eight OPEC+ members have boosted output targets by more than 2.7 million barrels per day - or about 2.5% of global supply - through a series of monthly increases.
Meanwhile, crude exports from top exporter Saudi Arabia hit a six-month high of 6.407 million bpd in August, data from the Joint Organizations Data Initiative showed on Wednesday, and are set to climb further.
A US Energy Information Administration report also showed record production of 13.6 million bpd last week.
US President Donald Trump said on Thursday that China has agreed to begin the process of purchasing US energy, adding that a very large-scale transaction may take place involving the purchase of oil and gas from Alaska.
However, analysts remained skeptical as to whether the US-China trade deal will boost Chinese demand for US energy.
"Alaska produces only 3% of total US crude oil output (not significant), and we think Chinese purchases of Alaskan LNG likely would be market driven," Barclays analyst Michael McLean said in a note.
