Iran’s strategic gasoline reserves have dropped to approximately 1.56 billion liters, with diesel reserves sitting at around 1.28 billion liters. Under normal consumption patterns, that’s enough to keep the country running for about 12 days. Under current conditions, estimates put the window at somewhere between 22 and 33 days before the tanks hit empty.
The math behind the crisis is brutally simple. Iran’s refineries can produce roughly 130 million liters of gasoline per day. The country burns through about 135 million liters daily. That 14 to 15 million liter daily deficit compounds every single day, steadily draining reserves that were never designed to be a permanent backstop.
How a blockade broke the supply chain
The US naval blockade on Iranian fuel imports, in place since roughly mid-July 2026, eliminated the safety valve that had historically filled the gap between domestic production and demand. Without those shipments arriving, the country is running on what it can produce domestically, and that isn’t enough.
War-related damage has made the production side even worse. Reports indicate 52 fuel storage tanks were destroyed across Tehran and Alborz provinces, with infrastructure losses estimated at around $1 billion. Refineries operating at reduced capacity due to conflict damage means the 130 million liter daily output figure may itself be optimistic on some days.
Panic at the pump
The visible consequences are already playing out on Tehran’s streets. Long queues have formed at petrol stations across the capital, with reports of stations limiting purchases to roughly 20 liters per vehicle. Some stations have closed entirely.
The government has responded by implementing daily fixed allocations to petrol stations, essentially rationing supply at the distribution level. It’s a familiar playbook for Iran, which imposed fuel rationing in 2019 when sudden subsidy cuts triggered nationwide protests that left hundreds dead.
Panic buying is accelerating the timeline. If panic buying subsides and consumption normalizes, reserves could stretch toward the 33-day mark. If hoarding intensifies and refinery damage worsens, 22 days becomes the more likely scenario.
Iran’s heavily subsidized fuel prices, which keep gasoline artificially cheap for consumers, are part of what drives the staggeringly high demand. Raising prices would reduce consumption but carries enormous political risk, as the 2019 experience demonstrated.
The broader energy picture
Government officials have publicly warned that strategic reserves cannot indefinitely sustain current shortfalls. The social stability dimension may ultimately matter more than the commodity price impact. Iran’s government has historically treated fuel subsidies as a core element of its social contract with citizens, and when that contract frays, as it did in 2019, the consequences can be swift and severe.
