The U.S. Strategic Petroleum Reserve stores oil for national security to ensure a reliable supply during emergencies or disruptions.

The U.S. Strategic Petroleum Reserve (SPR) is a government-owned stockpile of crude oil stored in underground salt caverns along the Gulf Coast. Its primary purpose is to ensure national energy security by providing a backup supply of oil in the event of emergencies such as natural disasters, geopolitical conflicts, or significant disruptions to global oil markets. The reserve helps mitigate the impact of supply shortages and stabilizes oil prices. While the SPR is not intended for regular use, it can be tapped into when necessary to prevent severe economic or energy disruptions in the U.S.
