Iran is facing a severe gasoline and diesel squeeze after the United States reimposed a naval blockade of Iranian ports on July 14, 2026, disrupting refined-fuel imports and effectively halting crude exports. Tehran has imposed purchase limits of roughly 20 liters per vehicle, while long lines and station closures have spread. Iran produces estimates ranging from 121 million to 130 million liters of gasoline daily against consumption of about 135 million liters, leaving a reported shortfall of 14 million to 15 million liters that imports previously covered. Earlier U.S. and Israeli strikes damaged refining and storage infrastructure, including 52 fuel-storage tanks across Tehran and Alborz provinces, with losses estimated at around $1 billion. Gasoline reserves of approximately 1.56 billion liters and diesel reserves of 1.28 billion liters would last about 12 days under normal consumption, while current depletion estimates range from 22 to 33 days depending on consumption and infrastructure conditions. The blockade has also stranded Iranian tankers and disrupted ship-to-ship transfers used to move crude to Chinese refineries, increasing pressure on supplies and social stability.
