The Strategic Petroleum Reserve, the largest government stockpile in the world, was set up after the Arab oil embargo in the 1970s and has been tapped in response to Operation Desert Storm in 1991, Hurricane Katrina in 2005, and Libyan supply disruptions in 2011.

The proposed drawdown would be in addition to about 260 million barrels of congressionally mandated sales through fiscal year 2027 intended to raise money for government programs.

Trump in 2017 called for selling off half the stockpile — which currently totals 635 million barrels — to help cut the budget deficit.
