The Department of Energy of the United States said it plans to sell five million barrels of oil from its strategic reserves.
Government officials said the sale is a trial that has been planned for months.
The decision comes at a time when global energy markets closely watch the developments of the conflict between Ukraine and Russia.
On the territory of Ukraine pass pipelines carrying Russian gas to the European Union.
However, the White House said the two events are not connected.
The decision lowered by 2% the price of crude oil on the New York Stock Exchange.
