North Sea crude, a reference in Europe, concluded the session on the International Exchange Futures at 1.09 dollars above the 81.43 at which it closed transactions on Friday.
The rise in Brent was attributed to relative optimism among investors regarding the state of crude supply, after a report from the Organization of the Petroleum Exporting Countries (OPEC) indicated that the daily production of its 13 members was in October 27, 9 million barrels, 0.3 percent more than in September.
Angola, Iran and Nigeria were those that increased their production the most, without violating the limits defined in the agreements reached with OPEC allies, namely the Russian Federation, said OPEC in its monthly report.
Outside these agreements is Iran, which, like Venezuela and Libya, is exempt from fulfilling its commitment to reduce its production, which has grown to levels not seen for years.
