SINGAPORE (Reuters) - Crude oil futures lost more ground on Monday as the market was weighed down by U.S. output climbing to a record-high and expectations that OPEC members will raise supplies.
Global benchmark Brent was down 34 cents, or 0.4 percent, at $76.45 a barrel by 0531 GMT, falling for a second session.
U.S. West Texas Intermediate (WTI) crude futures dipped 3 cents to $65.78 a barrel. Last week, the market lost around 3 percent, adding to a near 5-percent decline from a week before.
"Crude oil remained under pressure as the market remained focused on the discussion between OPEC members about whether they should increase production later this year," ANZ said in a note.
"In the U.S., the data also presented a gloomy picture. Crude oil production rose to another record, while drilling activity picked up again."
