"Arguably, the Japanese recession is pulling everything down, crude included. But the oil market has another and bigger problem: that the OPEC meeting will come and go without any change in production," said Andrew Lipow, president of Lipow Oil Associates in Houston.

Venezuela's Foreign Minister Rafael Ramirez said the OPEC will increase coordination in the face of the fall in oil prices, the South American government said in a statement on Monday, without elaborating.
"We will be united in terms of putting forth a common policy," said Ramirez, who until September was both oil minister and head of state oil company PDVSA.
Ramirez has been on a global tour of OPEC and non-OPEC nations to shore up support for an output cut.
Also on Monday, top Russian oil producer Rosneft announced its chief executive, Igor Sechin, will fly to Vienna on Nov. 25, just two days before the OPEC meeting to debate the plunge in oil prices.
The surprise announcement from the state-backed firm raised speculation that Sechin, a close ally of President Vladimir Putin, will discuss coordinating with OPEC.
Brent prices have fallen about 30 percent from a June high above $115 on oversupply concerns. On Friday, the market jumped almost $2 a barrel for its biggest gain in three weeks as support emerged after prices hit four-year lows under $80.
