The U.S.’ monthly petroleum exports exceeded imports for the first time on record during the month of September, the country’s Energy Information Administration (EIA) said in a statement on Thursday.

In September 2019, the U.S. exported 89,000 barrels per day (bpd) more petroleum, which includes crude oil and petroleum products, than it imported. This marked the first month on record that petroleum exports came higher than imports since monthly records began in 1973.

By comparison, the U.S. was importing 10 million bpd more petroleum than it was exporting in 2009, according to the EIA.
