What was said

… diesel to the United States, and is also getting G seven nations to release emergency fuel reserves to the U.S., even though many of those nations are themselves facing extremely bad scenarios of scarcity of fuel. So what this means, number one, is that the war on Iran is in fact having a catastrophic effect on U.S. Domestic diesel supplies. Why is that? Why is that?

What we found

Supports. Reuters (Oct 20, 2026) reports that diesel prices hit record highs because of disruptions from the Iran war and Ukrainian attacks on Russian refineries.[1]

Supports. BBC Verify finds that while both the Ukraine and Iran conflicts reduced global diesel exports, the fall in Gulf supplies due to the war with Iran has been greater.[2]

Supports. Estimates compiled by Bloomberg and checked with traders put Middle East diesel losses at about 770,000 barrels a day from March to August, more than double the roughly 350,000 barrels a day lost from Russia, and describe Iran-related disruption as the larger driver.[3]

Supports. The EIA attributes the soaring US fuel prices since late February to global supply shortages caused by the US-Iran war, alongside Ukraine's drone campaign against Russian refineries.[4]

Supports. DW experts call the war in Iran and the disruption of Strait of Hormuz shipping the main reason for high diesel prices.[5]

Context. Trump has blamed Ukraine's attacks on Russian refineries for the diesel price spike, a view the BBC and Bloomberg-based analysis weigh against the evidence on the Iran war's larger share.[2][3]

Context. The Conversation argues the Iran war pushed an existing crisis to a new level, with pre-existing US refinery capacity losses and Russia's war in Ukraine as longstanding contributing factors.[6]
