Despite The Decrease In The Price Of Oil, The Price Of Gasoline In Brazil Will Increase In 2026 Due To The Adjustment Of ICMS And The Growth Of The Profit Margins Of Distributors And Gas Stations.
Even in a scenario of cheaper oil and stable dollar, Brazilians will face new increases in the price of gasoline starting in 2026, as reported by Fipe Carros on Wednesday, 09/17. The increase is not related to production costs, but rather to two combined factors: the tax collection policy of the states and the increase in profit margins of distributors and gas stations.
State Taxes Pressuring Fuels
The decision to raise the ICMS was formalized by the National Council of Tax Policy (Confaz) and published in the Official Union Gazette in September. Starting in January 2026, the charge on gasoline and ethanol will increase from R$ 1.47 to R$ 1.57 per liter. Meanwhile, diesel will rise from R$ 1.12 to R$ 1.17, while cooking gas will increase from R$ 1.39 to R$ 1.47 per kilo.
States like São Paulo, Minas Gerais, and Rio de Janeiro, which cope with high debt levels, view ICMS as a crucial tool to keep revenues up to date and ensure access to credit lines. Since the tax is easy to collect and affects the entire population, it has become a pillar of the state fiscal policy.

Petrobras evaluates suspension of sales to distributors and considers canceling the cooking gas auction following guidelines from the Federal Government.

Lula reveals a masterstroke by Petrobras to undo a deal made by Bolsonaro, which involves the return of an important refinery that currently produces less than half of what was expected and makes Brazil dependent on international diesel.

A study confirms that the natural gas sector will reduce greenhouse gas emissions in Brazil by 0.5% and accelerate the energy transition by 2026.

Petrobras implements a severe adjustment and confirms a 55% increase in the price of aviation kerosene with a proposal for installment payments for the companies.
In addition to taxes, consumers face another obstacle: the increase in profit margins of distributors and gas stations. The Fuel Price Bulletin No. 28, published by Ineep, shows that, between January and August 2025, the gross margin on gasoline increased from 15.5% to 20.9%. This occurred even with the drop in refinery prices, which decreased from R$ 2.30 to R$ 1.80 per liter.
According to specialists, the difference has not been passed on to the final consumer. Thus, the drop in the cost of gasoline, instead of easing the burden on the population, has turned into additional profit for the distribution sector.
Impact On Diesel And Cooking Gas
The pattern of increase is not limited to gasoline. Diesel, an essential fuel for transporting goods and passengers, also shows growing margins: it rose from R$ 0.89 to R$ 0.91 per liter. In the case of cooking gas, used by millions of Brazilian families, nearly half of the price of the cylinder corresponds to the profit of distributors.
For economist Igor Lucena, the scenario reveals a political choice. “Oil has dropped, the dollar has stabilized, and still, fuels will rise. This is not tax policy; it is revenue policy,” he stated.
Analysts also warn that the situation could worsen if international conflicts drive up oil prices. Small adjustments in the global market, combined with the increase in ICMS and the inflated margins of distributors, have the potential to further pressure the price of gasoline and other fuels in 2026.
Deixe-me ver se entendi direito. Se as coisas estão bem, vamos aumentar os impostos para “melhorar”. Se as coisas estão mal, vamos aumentar impostos para zerar a dívida.
