Iran's September 2026 petrol change raised the price for consumption beyond 110 litres a month to 100,000 rials per litre. Reuters reported government spokesperson Fatemeh Mohajerani's announcement on September 6, ahead of the Tuesday start. She said the first 60 litres remained at 15,000 rials each and the next 50 at 30,000.
That structure changes the cost of additional driving sharply at the threshold. Using those published rates, 110 litres costs 2.4 million rials: 900,000 for the first block and 1.5 million for the second. Another 10 litres adds one million rials, taking a 120-litre bill to 3.4 million. This is a calculation of the stated schedule, not a claim about every driver's actual purchases.
Associated Press reporting from Tehran confirmed that the increase took effect early Tuesday, September 8. AP also reported the distribution company's chief saying August consumption reached 145 million litres daily against domestic production capacity of 122 million. The difference is 23 million litres a day, illustrating the supply pressure behind the policy.
The earlier adjustment had used a different threshold. Reuters' December 13, 2025 report described 60 litres at 15,000 rials and another 100 at 30,000, with purchases beyond 160 litres priced at 50,000. It quoted the spokesperson linking that measure to controlling consumption and smuggling. Thus the two dated accounts describe changes in both the expensive tier's price and the quantity available in lower tiers.
The historical comparison matters for interpreting a headline about doubling prices. The December excess-use rate was half September's, but a monthly bill also depends on how many litres fall into each block. The lower-rate allowance reported in September was 50 litres smaller than in December. Price and allowance are separate elements of the subsidy design; looking only at the highest pump rate misses that distinction.
