Can the Strategic Petroleum Reserve lower gas prices?

Mar 11th 2026

The Strategic Petroleum Reserve is the United States emergency crude stash in Gulf Coast salt caverns; tapping it can shave cents off pump prices but provides only a temporary cushion against broader supply shocks.

  • The SPR stores crude in 60 salt caverns at four Gulf Coast sites with a 714 million barrel capacity and currently holds about 415 million barrels.
  • Emergency SPR releases occurred in 1991, 2005, 2011, and 2022.
  • Analyses of the 2022 release estimate it lowered pump prices by roughly 13 to 33 cents per gallon.
  • The U.S. consumes about 20 million barrels of oil per day, so a 200 million barrel release equals roughly 10 days of supply.
  • SPR releases can ease prices and calm markets short term but cannot offset prolonged global supply disruptions.
  • Other countries and G7 members hold over 1.2 billion barrels in emergency stocks and could coordinate releases, but that option was not used in a recent meeting.
