Petrobras Announces 14% Decrease in Natural Gas Prices for Distributors Starting in August. Decrease Reflects Drop in Brent and Appreciation of the Real.
Petrobras announced that starting August 1, 2025, the selling prices of natural gas molecules to distributors will be reduced by an average of 14%, according to existing contracts with state concessionaires. This measure, which applies nationwide, follows the quarterly variation linked to the price of Brent oil and the exchange rate of the dollar, two of the main factors that make up the adjustment formula for contracts established with the company.
The price drop occurs after an 11% decrease in Brent and a 3.2% appreciation of the real against the dollar during the reference period.
According to Petrobras, this move reinforces the pricing mechanisms adopted and can represent relief in costs for consumers — although the final impact depends on factors such as transportation, taxes, and distribution margins.

Cumulative Reduction Exceeds 30% Since 2022
Petrobras reported that, with this new decrease in August, the value of the natural gas molecule has accumulated a reduction of 32% since December 2022.
If the performance incentives and demand incentives — implemented by the company in 2024 — are fully applied by the distributors, the cumulative cut may reach over 33%, amplifying the positive effects for the market and end consumers.
Factors Influencing Natural Gas Prices
Despite the decrease announced by Petrobras, the final value of natural gas reaching homes, businesses, and industries does not depend solely on the molecule sold by the company.
Other elements contribute to the price composition, such as transportation to the distributors, the supply portfolio of each company, commercial margins, and state and federal taxes.
Furthermore, in the case of Compressed Natural Gas (CNG), there is also a price variation at the resale stations, which operate with their own margins and commercial strategies.
Petrobras Reinforces Commitment to Transparency
In an official statement, the company reinforced its commitment to transparency in gas pricing and emphasized that quarterly adjustments allow prices to reflect conditions in the international market and the national economy.
The adoption of performance bonuses and demand incentive mechanisms also demonstrates Petrobras’ concern to maintain the competitiveness of natural gas in the country.
