"The government has decided to increase the price of unleaded gasoline, which is primarily used by luxury vehicles," Mohsen Hajimirzaei, chief of staff to President Masoud Pezeshkian, said on Monday night.
Hajimirzaei added that the decision was delayed to address concerns about its impact on those whose livelihoods depend on unleaded fuel, in a likely reference to taxi drivers.
"To eliminate worries over the price hike’s effect on vulnerable groups, the decision took considerable time."
Price increases tend to make other fuel types more costly, economic analysts speaking to Iranian state TV and Persian-language outlets abroad said, adding that they also generally drive up the cost of goods and services.
Previously, President Pezeshkian had proposed reducing the gasoline quota for low-income households while capping allocations for wealthier families.
Typically, fuel price increases are accompanied by a quota system for subsidized gasoline, where consumption beyond that quota is charged at higher rates.
