Petrobras reduces the price of diesel A by 0.3515 reais from June 1st to neutralize re-encumbrance

Petrobras announced a reduction in the sales prices of diesel oil A. The measure will come into force from June 1st, impacting the value of the fuel at distributors. The discount will be R$0.3515 per liter, aiming to neutralize the re-encumbrance of PIS and Cofins, which will also come into effect on the same date, as communicated by the state-owned company.

The initiative is in line with the economic subsidy established by the federal government. The company detailed that the action is in compliance with Medida Provisória No. 1,358, of May 13, 2026. Além In addition, the reduction follows Decreto No. 12,984 and Portaria MF No. 1,584, of May 29, 2026, with the value set by Ministério of Fazenda.

Impacto direct on diesel A prices

Petrobras will adjust the average selling price of diesel oil A for distributors. The value will increase from R$3.65 to R$3.30 per liter from the beginning of June. Esta change represents a significant change for the transport sector and for end consumers of fuel in the country.

The current pricing of diesel by Petrobras already shows considerable variation compared to previous periods. The new price of R$3.30 per liter is 37.4% lower than that practiced on December 31, 2022. Esta comparison considers the inflation accumulated in the period, indicating a trajectory of more affordable prices for the fuel.

The neutralization of PIS and Cofins re-encumbrance is a central point of the measure. Para the end consumer, the discount granted by the economic subsidy will have the effect of offsetting the increase in taxes. Desta way, the impact of the reencumbrance, which also comes into force on June 1st, should not be felt directly on the final amount paid at the fuel pumps.

Detalhes of economic subsidy and its regulation

The economic subsidy that supports the reduction in diesel prices was established through a set of normative acts by the federal government. The initiative seeks to offer financial support to stabilize the cost of fuel and guarantee supply on the national market.

The legal basis for the reduction was established by Medida Provisória nº 1,358/2026. Esta MP, dated May 13, 2026, outlined the guidelines for awarding the grant. Outras regulations complement this measure, ensuring its effective application.

The legal acts that support Petrobras’s action include:
• Medida Provisória nº 1,358, of May 13, 2026, which establishes the economic subsidy.
• Decreto nº 12,984, which details aspects of the implementation.
• Portaria MF nº 1,584, of May 29, 2026, of Ministério of Fazenda, which sets the equivalent value of the discount.

The combination of these legal instruments allows Petrobras to implement a reduction of R$0.3515 per liter of diesel A. Este specific value corresponds to the amount determined by government authorities to subsidize part of the fuel cost, mitigating the effects of the re-encumbrance.

Nova government subsidy for diesel

The federal government authorized a new economic subsidy for diesel oil for road use. Esta additional measure was established by Medida Provisória nº 1,363/2026, published on May 30th. The objective is to ensure price and supply stability, guaranteeing the continuous supply of diesel throughout the country.

The new subsidy provides for a value of R$1.12 per liter. Este financial support extends until December, seeking to contain the impacts of fluctuations in the international oil market. Conflicts in Oriente Médio have caused input prices to rise, creating challenges for internal fuel pricing.

Petrobras is in the process of evaluating the terms of this Medida Provisória nº 1,363/2026. The company reviews the details of the new grant to determine how it will be applied to its operations. Qualquer Petrobras’s future decision on this topic will be disclosed in a transparent and timely manner to the national market, maintaining clarity for all economic agents.
