The International Energy Agency (IEA) believes the U.S. is on track to become a sustained net oil exporter in either late 2020 or early 2021, after briefly achieving this "major milestone" earlier in the year.
In September, the U.S. exported 89,000 barrels per day (b/d) more petroleum (crude oil and other petroleum products) than it imported, according to official data published earlier this month.
"On a historic note, in September, the United States momentarily became a net oil exporter… This is a major milestone on its path to becoming a sustained net exporter, which is likely to be late in 2020 or early in 2021," the IEA said in its closely-watched report published on Friday.
"However, this does not mean that energy independence has been achieved: The United States remains a major crude oil importer."
