Petrobras increased gasoline prices by R$0.48 per litre effective Friday, May 29 [1].

This adjustment marks the first formal price hike since July 2024 [3]. The move is significant because it tests the Brazilian government's ability to shield consumers from inflation through subsidies while maintaining the competitiveness of ethanol, a primary alternative fuel in the country.

While the base increase is R$0.48 per litre [1], a federal subsidy offsets the majority of that cost. The net increase for consumers at the pump is R$0.04 per litre [2]. This intervention follows efforts by the administration to stabilize fuel costs across the nation.

Jean Paul Prates, CEO of Petrobras, said the company had to be cautious due to competition with ethanol. The company's pricing strategy often balances international oil market trends against the domestic price of sugarcane-based fuel [7].

Government officials have sought to minimize the impact on the public. A spokesperson for the Presidency of the Republic said the government intends to prevent gasoline prices from rising for the final consumer [8]. Reports indicate the administration is preparing a provisional measure to further curb price hikes [10].

Market analysts have noted price volatility even before this formal announcement. An analyst from the ANP said gasoline prices had already risen at some pumps despite the lack of a formal Petrobras adjustment [9]. For context, the average price of gasoline for the week ending Feb. 28 was R$6.28 per litre [5], showing a weekly variation of -0.32% [6].

Petrobras is now implementing this new pricing structure nationwide to align its revenue with operational costs while adhering to the government's broader economic goals.

The net increase for consumers at the pump is R$0.04 per litre.

The minimal net increase reflects a tension between Petrobras' need to maintain commercial viability and the Brazilian government's political priority to control inflation. By using subsidies to absorb nearly 92% of the price hike, the state is effectively decoupling pump prices from the company's internal pricing shifts to avoid public discontent and protect the ethanol market's stability.
