Ministry of Finance maintains diesel subsidy at R$ 2.12 per liter

The Ministry of Finance published an ordinance this Friday (25) maintaining the diesel subsidy at R$2.12 per liter of fuel.

The measure was necessary, explained the ministry, "given the persistence of volatility in international oil and fuel prices". This volatility is due to the war in Iran, which impacts the global distribution of oil, from which diesel is derived.

The price of a barrel of oil has remained around the US$100 level in recent weeks.

The Treasury ordinance is necessary because the initial subsidy was based on MP (Provisional Measure) 1363, of May 30 of this year. It set the subsidy at R$1.12 per liter of diesel and will become effective this Saturday (26).

Before that, on September 11, 2026, the federal government issued another MP, number 1391, authorizing the Ministry of Finance to define the value of the subsidy.

Based on this second measure, the government created an additional subsidy of R$1 per liter, which added to the first MP brought the subsidy to R$2.12.

With the expiration of the first MP, this Friday's ordinance replaces its effect, maintaining the subsidy at the level it already is, R$ 2.12.

"The change, therefore, does not imply an increase in the subsidy, but guarantees the maintenance of the total amount currently charged, avoiding its reduction with the end of the validity of MP nº 1,363/2026", explained, in a note, the Treasury.
