West Texas Intermediate dropped a second day as Libya’s oil production rebounded and the threat of military strikes against Syria receded, damping concern that Middle East supplies may be disrupted.

Futures fell as much as 1 percent and are headed for a second weekly decline. Libyan output yesterday was more than five times higher than earlier this month, according to its oil ministry. Syria will provide information about its chemical weapons and open facilities to inspectors, President Bashar al-Assad said Sept. 18 in an interview with Fox News.

Libyan oil output is set to increase to 800,000 barrels a day, Ibrahim Al Awami, director of measurement at the oil ministry, said by phone from Tripoli yesterday. Supply fell to as low as 150,000 barrels earlier this month, compared with a 2013 high of 1.4 million in April, the International Energy Agency said in a Sept. 12 report.

Oil prices will drop further next week after a U.S.-Russian accord reduced the risk of an American attack on Syria.
