June 2 (Reuters) - Grades broadly fell on Monday, dealers said, as traders braced for a jump in global crude supplies.
The world’s largest group of oil producers, OPEC+, stuck to its guns on Saturday with another big increase of 411,000 barrels per day for July as it looks to wrestle back market share and punish over-producers.
Meanwhile, Canadian oil producer Cenovus Energy CVE.TO declared force majeure on its supply of Christina Lake Dil-bit heavy crude due to wildfires in the oil-producing province of Alberta, two trading sources said.
The wildfires have affected more than 344,000 bpd of oil sands production, or about 7% of the country's overall crude oil output, according to Reuters calculations.
On the demand side, U.S. oil refiners are expected to have about 263,000 barrels per day of capacity offline in the week ending June 6, increasing available refining capacity by 2,000 bpd, research company IIR Energy said on Monday.
