OPEC’s crude oil production climbed last month as group leader Saudi Arabia bolstered production amid rising regional tensions, a Bloomberg survey showed.

Output from the Organization of the Petroleum Exporting Countries increased by 640,000 barrels a day, the biggest hike since June, with the Saudis accounting for about half of the addition, according to the survey. The 12 members collectively pumped 29.52 million barrels a day.
