The US Strategic Petroleum Reserve, the world's largest crude oil storage facility with capacity for 714 million barrels, was established following OAPEC's 1973 oil embargo to protect against supply disruptions and price shocks. Created using underground salt dome storage, the SPR has become a key energy policy tool, though it has operational limits on how much oil can be safely withdrawn.
The Strait of Hormuz has become the world's most critical crisis in 2026, with a seven-month conflict trapping over 600 ships in the Persian Gulf, driving oil prices above $100 per barrel, and expanding to threaten the Malacca Strait and East Asian shipping lanes. Diplomatic solutions have failed, 50,000+ US troops remain deployed indefinitely, and a parallel 'dark fleet' of 150+ tankers operates covertly, causing unreported casualties and environmental damage.
