The federal government has expanded diesel subsidies and extended fuel price containment measures until July 31. The main change is a subsidy of R$ 1.12 per liter of diesel oil for national refineries and importers, which according to G1 takes effect this Monday (1st). The benefit replaces two subsidy programs ending on May 31: one of R$ 0.32 per liter since March and another from April with values of R$ 0.80 and R$ 1.20 per liter.

"Uma delas é uma subvenção de R$ 1,12 por litro de óleo diesel às refinarias nacionais e aos importadores do combustível, que entra em vigor nesta segunda-feira (01)."

IstoÉ

"As novas regras entram em vigor nesta segunda-feira, 1º de setembro, e atingem diesel, gás de cozinha, biodiesel e querosene de aviação."

The government also doubled resources for cooking gas (LPG) subsidies, from R$ 330 million to R$ 660 million, maintaining a benefit equivalent to R$ 11 per 13-kilo cylinder until July. Federal tax exemptions on aviation kerosene and biodiesel were extended until July 31. Planning Minister Bruno Moretti estimated the total cost of measures at R$ 30.5 billion, but stated there would be no impact on public accounts due to compensation from other revenues. ?

"§ 4º A subvenção econômica de que trata o caput terá vigência por dois meses, contada da data de edição do ato de que trata o § 2º, podendo ser prorrogada por ato do Poder Executivo federal."

Planalto

"Diante da demora na tramitação da matéria, o governo editou, em 13 de maio, uma medida provisória autorizando a concessão de subvenções econômicas a produtores e importadores de combustíveis em valor equivalente aos benefícios tributários que deixariam de vigorar."

The measures respond to delays in Congress processing a complementary bill that would authorize using extraordinary oil revenues to compensate for fuel tax reductions. The MP functions as a kind of 'cashback' — producers and importers resume normal PIS and Cofins collection, but receive subsidies equivalent to tax amounts.

"De acordo com o ministro do Planejamento, Bruno Moretti, o conjunto das medidas terá custo estimado de R$ 30,5 bilhões. Apesar disso, o governo afirma que não haverá impacto nas contas públicas, sob o argumento de que a compensação virá de outras receitas, como tributos incidentes sobre o diesel e royalties pagos pela exploração de petróleo."

3. What we don't know yet (3)
  • What is the exact effective date of the subsidies — June 1st or September 1st?

    Why it's still unknown: The Finance Ministry act that would define values and start the two-month period was not found in the DOU until May 31, and there is direct contradiction between G1/NSC Total (June 1st) and IstoÉ Dinheiro (September 1st).

  • What specific constitutional test does MP 1.358/2026 need to pass for direct subsidies to private companies?

    Why it's still unknown: No outlet analyzed the constitutional basis for federal authority to grant economic subsidies to the private sector or STF precedents on this type of intervention.

  • Are there ADIs or formal legal challenges already filed against MP 1.358/2026?

    Why it's still unknown: No source reported specific judicial contestation, although this type of executive act is traditionally challenged in the STF.
