Saudi Arabia says it is extending oil production cuts through September in a move that could potentially increase gas prices in the U.S.

The kingdom will extend the “voluntary cut” of 1 million barrels a day, totaling approximately 9 million barrels per day for the month of September, according to a statement from the Ministry of Energy carried on the state-run Saudi Press Agency.

An anonymous official was quoted as saying that the cut “can be extended or deepened” if the need arises and is aimed at “supporting the stability and balance of oil markets.”
