CMC chief markets analyst Michael Hewson told the news agency: "Expectations around today’s OPEC meeting are quite low, with some speculation about the potential for some form of quota or freeze, but the likelihood is that nothing will change."
OPEC’s overall production has remained largely flat this year despite an increase in production by its Middle Eastern producers.
