Reduction announced by the state company takes effect on June 1, 2026, changes prices for distributors and occurs simultaneously with the resumption of federal taxes on fuels, moving the transport and logistics sector throughout the country.
Petrobras announced a new reduction in the price of diesel oil sold to distributors. The measure began to take effect this Monday, June 1, 2026, and represents a cut of R$ 0.35 per liter in the price of diesel A sold by the state company. The information was released by Petrobras itself in a note sent to the press on Sunday, May 31.
The decision comes at an important time for the fuel market. Additionally, it arrives simultaneously with the resumption of federal tax collection on diesel, a fact that could create pressure on prices for consumers and transport companies.
With the change, Petrobras’s average selling price to distributors went from R$ 3.65 to R$ 3.30 per liter. In this way, the state company seeks to reduce part of the impacts caused by the tax re-oneration that came into effect at the same time.

Cut in diesel occurs along with the resumption of federal taxes
The announcement by Petrobras comes amid a new stage of the federal government’s fuel policy. In this sense, the reduction of R$ 0.35 per liter has the potential to offset part of the additional costs generated by the return of PIS and Cofins charges.
According to the state company, for the end consumer, the discount is equivalent to the value of the economic subsidy granted by the federal government. Therefore, the measure tends to neutralize the effects of the tax re-oneration scheduled for the beginning of June.
Furthermore, the movement was accompanied by a new action by the government. On May 30, 2026, the Union published Provisional Measure No. 1,363/2026, authorizing a new economic subsidy for producers and importers of road-use diesel oil.
The initiative establishes a benefit of R$ 1.12 per liter. According to the official text, the objective is to contribute to price stability and ensure the supply of fuel throughout the national territory.
New subsidy seeks to ensure supply and stability in the market
The new policy announced by the government aims to reduce fluctuations in the fuel market. Additionally, it seeks to offer greater predictability for sectors highly dependent on diesel, such as freight transport, agribusiness, and logistics.
Diesel remains one of the most important fuels in the Brazilian economy. Therefore, any change in its price usually has repercussions in different productive segments.
Meanwhile, producers, importers, and distributors are monitoring the impacts of Provisional Measure No. 1,363/2026. The sector’s expectation is to understand how the benefit could influence operational costs in the coming months.
Moreover, experts note that measures aimed at diesel have an indirect effect on merchandise prices, as road transport accounts for a large part of cargo movement in Brazil.
Petrobras is still assessing the impacts of the government’s measure
Despite the announced reduction, Petrobras reported that it is still evaluating the terms of the new economic subsidy authorized by the federal government.
According to a statement from the company, any decision related to the topic will be disclosed to the market in due course. Thus, investors, distributors, and consumers should follow the next positions of the state company.
Meanwhile, the reduction of R$ 0.35 per liter is already part of the company’s commercial policy starting June 1, 2026. Consequently, the market begins the week monitoring the measure’s effects on the supply chain and on the prices charged at fuel stations.
According to information released by VEJA magazine and Petrobras on June 1, 2026, the reduction in diesel prices occurs alongside the implementation of a new federal economic subsidy aimed at road fuel, expanding the debate on logistical costs and supply in the country.
Do you believe that the reduction announced by Petrobras will fully reach the final consumer at the stations, or will part of the discount be lost along the way? Share your opinion in the comments.
