Strategic Petroleum Reserve (SPR)
The world's largest government-owned emergency petroleum stockpile, stored in salt caverns along the U.S. Gulf Coast. Current capacity: ~714 million barrels; current inventory: ~370-400 million barrels.
Why It Matters
The SPR is America's insurance policy against oil supply disruptions. Its largest-ever release (180 million barrels in 2022) helped moderate gasoline prices after Russia's invasion of Ukraine.
