In brief
The government chose to hold pump prices with public money: R$ 7 billion a month between tax relief and subsidy, funded by the expected windfall from the very oil that is expensive.
Petrobras used the fiscal cover to restore prices without consumers noticing.

Lula signed on September 9 a decree cutting PIS/Pasep and Cofins rates on gasoline by R$ 0.63 a litre, taking the federal burden to R$ 0.16 a litre, and zeroing contributions on hydrous ethanol, worth R$ 0.19 a litre, replacing the R$ 0.44 subsidy of provisional measure 1,358, which lapsed, per the Finance Ministry, Agência Brasil, InfoMoney and Exame.

Provisional measure 1,389/2026, published in the Official Gazette on September 9, opens R$ 6.605 billion in extraordinary credit, of which R$ 5.607 billion for the road-diesel subsidy, at an adjustable initial R$ 1 a litre, and R$ 998 million for other derivatives, managed by the Energy Ministry through ANP, per g1, Agência Senado and Agência Brasil.

Planning Minister Bruno Moretti estimated the impact at R$ 7 billion a month, R$ 2 billion on gasoline and ethanol and R$ 5 billion on diesel, and Finance executive secretary Rogério Ceron said he expects over R$ 10 billion in extraordinary oil revenue, per Agência Brasil and Money Times.

Petrobras said on the evening of September 9 it is dropping the R$ 0.44 a litre discount and raising gasoline by R$ 0.19 a litre from September 10, to R$ 3.24 on average to distributors, with the consumer effect offset by the tax cut, per Exame, Money Times and InfoMoney; Poder360 describes the increase as R$ 0.63, adding the end of the discount to the adjustment.
