Some oil price forecasts are being cut for 2017 Traders said Brent was being weighed by fresh production records from the Organization of the Petroleum Exporting Countries (OPEC), which pumped out a record 33.6 million barrels of crude oil per day in September PRODN-TOTAL .
"Record supply from OPEC year-to-date, weaker global GDP estimates, and still elevated inventories cause us to lower and flatten our oil price outlook," Bernstein Energy said in a note to clients on Monday.
"We reduce our Brent forecast to $60 per barrel in 2017 ($70 per barrel before) and $70 per barrel in 2018 ($80 per barrel before)," it added.
Despite Monday's falls, analysts said that traders were cautious about driving the market much further down, largely because of a plan by OPEC to cut output in an initiative to rein in a global production overhang, which currently sees around half a million barrels of crude pumped every day in excess of demand.
OPEC is scheduled to meet on November 30 to discuss a production cut. The producer cartel hopes non-OPEC members, particularly Russia, will join a potential cut.
"With (non-OPEC member) Russia expressing an interest to join the agreement, investors are reluctant to get too bearish," ANZ bank said on Monday.
