Markets have been further tightened by USA sanctions against oil exports from OPEC members Iran and Venezuela. A recent EIA forecast also showed that the United States would become a net exporter of crude oil and petroleum products on a monthly basis in 2019 and on an annual basis in 2020.
"While oil demand is expected to grow at a moderate pace in 2019, it is still well below the strong growth expected in the non-OPEC supply forecast for this year", OPEC said in the report.
For 2020, the government said it expected USA crude oil demand to rise by 220,000 bpd to 21.03 million bpd, unchanged from previous forecasts. Crude oil imports to the United States fell last week by 523,000 bpd to 6.4 million bpd.More news: Watch The Trailer For 'The Disappearance of Madeleine McCann'
