A government in an election year trying to avoid the political damage that inflation inflicts
Diante de um choque geopolítico que fechou o Estreito de Ormuz e dobrou o preço do petróleo bruto em questão de semanas, o governo Lula recorreu a um decreto de emergência para conter o avanço dos preços dos combustíveis, subsidiando a gasolina em até R$0,89 por litro. A medida, anunciada em 13 de maio de 2026, suspende na prática tributos federais embutidos em cada litro vendido, transferindo esse custo ao Estado em vez de ao consumidor. É um gesto que revela a tensão permanente entre a lógica do mercado global e a responsabilidade política doméstica — especialmente em ano eleitoral.
- O fechamento do Estreito de Ormuz disparou o Brent de US$60 para mais de US$100 por barril, ameaçando transformar os postos de gasolina brasileiros em termômetros visíveis de uma crise distante.
- A Petrobras já havia avisado que reajustes nas refinarias eram iminentes, e o projeto de lei alternativo (PLP 114) que permitiria cortes tributários compensados por receitas do petróleo estava travado na Câmara.
- Sem saída legislativa imediata, o governo editou uma medida provisória que entra em vigor de imediato, mas precisa de aprovação do Congresso em 120 dias para não caducar.
- O subsídio ao diesel, suspenso desde março, aguarda o vencimento da medida anterior antes de ser ativado — sinalizando que o governo planeja uma cobertura mais ampla dos combustíveis.
- O Brasil se vê diante de uma escolha clássica: absorver o custo fiscal do choque externo ou repassá-lo ao cidadão e enfrentar o desgaste político que a inflação nos combustíveis historicamente provoca.
Na quarta-feira, 13 de maio de 2026, o governo Lula anunciou uma medida provisória para subsidiar a gasolina em até R$0,89 por litro — valor equivalente à soma dos tributos federais PIS, Cofins e Cide embutidos em cada litro vendido. O subsídio será pago diretamente a produtores e importadores pela Agência Nacional do Petróleo, com os valores específicos a serem publicados pelo Ministério da Fazenda nos próximos dias.
A origem da crise está a milhares de quilômetros do Brasil. Um conflito no Oriente Médio, iniciado em 28 de fevereiro, levou ao fechamento do Estreito de Ormuz — por onde passa um quinto de todo o petróleo negociado no mundo. O resultado foi uma disparada do Brent de US$60 para mais de US$100 por barril em poucas semanas, pressionando refinarias e postos de combustível brasileiros.
A Petrobras já havia sinalizado reajustes iminentes. Sua presidente, Magda Chambriard, alertou publicamente na véspera do anúncio que os preços nas refinarias subiriam em breve. O governo tentava uma solução legislativa — o PLP 114, que permitiria reduzir tributos federais sobre combustíveis usando receitas excedentes do petróleo —, mas o projeto, enviado à Câmara em abril sob regime de urgência, estava parado.
Diante do impasse, o Executivo optou pela medida provisória: mais rápida, mas condicionada à aprovação do Congresso em até 120 dias. Para o diesel, o governo aguarda o vencimento do subsídio anterior, de março, antes de acionar o novo mecanismo. A escolha revela um governo que, em ano eleitoral, prefere arcar com o custo fiscal a deixar que o preço nos postos se torne símbolo de descaso com o bolso do cidadão.
On Wednesday, May 13th, the Lula administration moved to shield Brazilians from surging fuel costs by issuing an emergency decree that would subsidize gasoline by up to R$0.89 per liter. The measure, announced jointly by the Ministries of Mines and Energy and Finance, targets the federal taxes embedded in every liter sold—PIS, Cofins, and Cide combined—effectively capping what consumers pay at the pump.
The subsidy will flow directly to gasoline producers and importers through the National Petroleum Agency, with the Finance Ministry to publish specific subsidy values in coming days. The decree also applies to diesel, though the government is holding that expansion in reserve, waiting for an earlier diesel subsidy from March to expire before activating the new one. The measure takes effect immediately upon publication but carries a hard deadline: Congress must approve it within 120 days, or it loses force.
This is a government in an election year trying to avoid the political damage that inflation inflicts. Fuel prices have become a flashpoint because of geopolitical upheaval. On February 28th, conflict in the Middle East destabilized global oil markets. The closure of the Strait of Hormuz—a chokepoint through which one-fifth of the world's oil passes—sent Brent crude rocketing from $60 to above $100 per barrel. That shock rippled directly into Brazilian refineries and gas stations.
Petrobras, the state oil company, had already signaled the pain coming. On Tuesday, May 12th, company president Magda Chambriard told the public that fuel prices at Petrobras refineries would rise soon. The company was waiting for Congress to bless a different approach: a complementary bill that would let the government trim federal fuel taxes and offset the lost revenue by tapping surplus earnings from oil exports. That bill, PLP 114, landed at the Chamber of Deputies on April 23rd under an expedited track, but it has stalled.
Faced with legislative gridlock and market pressure, the government pivoted to the emergency decree—a faster tool that bypasses the usual legislative process but requires retroactive approval. The math is straightforward: gasoline carries R$0.89 in federal tax per liter. Diesel had R$0.35 in combined PIS and Cofins taxes suspended back in March. Now the government is saying it will absorb some or all of those levies, keeping prices lower than they would otherwise be.
The stakes are real. A Middle East conflict that began less than three months ago has already doubled the price of crude oil globally. Brazil, which imports refined fuel and is vulnerable to these swings, faces a choice between absorbing the cost through subsidies or passing it to consumers and risking the political backlash that comes with visible price spikes in an election year. The Lula government has chosen the subsidy route—at least for now, and at least until Congress decides whether to make it permanent.

La Conversación del Hearth Otra perspectiva de la historia
Why does the government need an emergency decree instead of just passing a normal law?
Because normal laws take time, and fuel prices move fast. The decree works immediately. Congress has 120 days to approve it, but by then the market has already adjusted. It's a way to act now and ask permission later.
Who actually pays for this subsidy?
Technically, the government does—which means taxpayers. The money comes from the federal budget, though the government is hoping to offset some of it with extra revenue from oil exports. But that's the bill they're still trying to pass.
Why does the Strait of Hormuz matter so much?
Because one-fifth of the world's oil flows through it. When it closes, even for a few days, the price of every barrel everywhere goes up. Brazil doesn't produce enough refined fuel for itself, so it imports. Higher global prices mean higher prices here.
Is this subsidy permanent?
No. It's temporary—120 days maximum unless Congress approves it. And even then, the government is planning to phase it out for diesel once the old March subsidy expires. It's a bridge, not a solution.
What happens if Congress doesn't approve it?
The decree stops working after 120 days. Prices would likely jump. That's why the government is pushing hard for the complementary bill—to have a legal framework in place before the emergency measure expires.
