Overseas demand strains U.S. fuel reserves amid Iran conflict

Record overseas demand for U.S. diesel, propane, gasoline and jet fuel has drained commercial fuel reserves from the Gulf Coast to the East Coast as the escalating U.S.-Iran conflict tightens global energy markets. According to the Energy Information Administration’s latest data released July 8, 2026, propane exports hit record highs, while diesel, gasoline and jet fuel shipments surged, pushing U.S. inventories to multiyear seasonal lows. The export surge coincides with Russia’s diesel export ban and renewed U.S. airstrikes on Iran, which have sent oil and fuel prices soaring. Diesel futures in New York jumped as much as 14% in a single session—the largest intraday gain since the conflict began. U.S. diesel exports, primarily bound for South America with Brazil as the top recipient, also reached Europe, accounting for about 14% of total shipments. Meanwhile, propane cargoes were largely Asia-bound, targeting China and Japan, though final destinations may shift as vessels remain in transit. On the domestic front, U.S. diesel and gasoline stockpiles have fallen to their lowest seasonal levels in years, raising concerns about the country’s ability to sustain its role as a global fuel supplier. Gasoline inventories have not been this low at this time of year since 2012. Analysts warn that with Russian diesel off the global market and U.S. strikes on Iran continuing, demand for American fuel is unlikely to ease, further straining already depleted reserves.
