US Oil Reserves Hit 45-Year Low as Iran War Escalates

The Federal government of the United States is facing a critical decline in crude oil reserves, with the Strategic Petroleum Reserve reaching its lowest level since 1983. Data from Barchart indicates only slightly more than 15% of the supply remains. This depletion follows a series of military exchanges and the collapse of a tentative ceasefire between the United States and Iran, leading to a second closure of the Strait of Hormuz.

The 2026 Iran war initially erased 15 million barrels per day from global circulation after Iran blockaded the strait and attacked 30 Middle Eastern refineries. To prevent a global recession, the International Energy Agency coordinated a record release of 400 million barrels from strategic reserves. While the United States, Venezuela, and Norway increased production, and China stabilized markets by drawing down its 1.9 billion-barrel stockpile, supply remains strained.

Additional pressures have emerged as the Houthis announced a maritime blockade on Saudi Arabia, threatening oil flows through the Bab Al Mandeb strait. Despite a global demand decrease of 4 million barrels per day due to refinery damage and China's shift toward electric vehicles, U.S. gas prices have returned to $4 per gallon. Officials warn that literal fuel shortages could occur within weeks. China is now expected to resume oil imports after previously reducing them following U.S. attacks on Iran in February.
