OPEC oil output decreased in August, as reported by a Reuters survey, primarily due to disruptions in Saudi exports stemming from the conflict in Iran and U.S. sanctions affecting Iran's shipments. The survey indicated that the crude output from the 11-member Organization of the Petroleum Exporting Countries declined by 640,000 barrels per day from the previous month, reaching 19.71 million barrels per day. Although seven members of the broader OPEC+ group, including Russia, had agreed to boost production in August, the ongoing Middle East conflict made this target unattainable. The survey's findings are based on flow data from financial group LSEG, information from tracking companies like Kpler, and insights from sources within oil companies, OPEC, and consulting firms.
