NYMEX floor trading resumes on Tuesday.

Saudi Arabian Oil Minister Ali al-Naimi said Opec would "probably stay the course" as he forecast a pick-up in demand and prices eventually rising towards $75 a barrel.

"I think that everybody is in agreement," Khelil told Reuters at the G8 energy summit in Rome.
