Governo estende isenção fiscal para querosene de aviação e biodiesel

Aviation kerosene now accounts for 45 percent of airline operating costs
After Petrobras's April price increase, the fuel became the single largest expense for Brazilian airlines.

When Petrobras raised fuel prices by half in April, Brazil's government faced a familiar dilemma: let market forces reshape the cost of movement, or intervene to protect the arteries of commerce. By extending tax exemptions on aviation kerosene and biodiesel indefinitely, Brasília has chosen, at least for now, to hold the line — absorbing 30.5 billion reais in foregone revenue to keep planes flying and trucks rolling without passing the shock to ordinary Brazilians. It is a wager that stability today is worth the fiscal uncertainty of tomorrow.

  • Petrobras's 50% fuel price hike in April struck aviation and transport like a sudden storm, with kerosene alone now consuming 45% of airline operating costs.
  • Airlines and cargo carriers faced an impossible choice: absorb losses that would eventually hollow them out, or raise prices and push the pain onto passengers and consumers.
  • The government moved quickly, assembling a nine-measure relief package worth R$30.5 billion in tax concessions to prevent a cascade of price increases across the economy.
  • Two of those measures — exemptions on aviation kerosene and biodiesel — have now been extended indefinitely, signaling that the state sees these fuels as too strategically vital to leave unprotected.
  • The relief buys breathing room, but the deeper tension endures: Petrobras controls the refinery gate price, and tax exemptions can soften but not dissolve the underlying pressure of global crude markets.

In April, Petrobras announced a 50 percent increase in fuel prices, sending shockwaves through Brazil's transportation sector. The government responded within weeks with a nine-measure relief package — and in late May extended two of those measures indefinitely: tax exemptions for aviation kerosene and biodiesel.

The stakes are not abstract. Aviation kerosene now accounts for 45 percent of what airlines spend to keep their planes airborne. Brazil's airline association had watched the Petrobras announcement with alarm, knowing that without relief, carriers would face a stark choice between raising ticket prices or absorbing losses they could not sustain. Biodiesel carries a different but equally broad weight: blended into diesel sold at pumps nationwide, it flows through every truck, bus, and delivery van in the country. When its cost rises, the price of nearly everything transported rises with it.

The April package carried a public cost of 30.5 billion reais in foregone tax revenue — the price of holding inflation at bay in a fuel-dependent economy. The indefinite extension of kerosene and biodiesel exemptions reflects a deliberate judgment that these inputs are too strategically important to be left entirely to market forces.

Yet the relief has limits. Petrobras sets prices at the refinery gate, and tax exemptions can cushion but not override the economics of crude oil markets. The government has purchased time and stability for the sector, but the fundamental question lingers: how long can the state absorb these costs, and what happens to fares, freight, and grocery bills when it can no longer do so?

In April, Petrobras announced a 50 percent increase in fuel prices, a move that sent shockwaves through Brazil's transportation sector. Within weeks, the government responded with a nine-measure relief package designed to cushion the blow—and on this day in late May, it extended two of those measures indefinitely: tax exemptions for aviation kerosene and biodiesel.

The decision reflects how deeply fuel costs have burrowed into the operating structure of Brazilian commerce. Aviation kerosene alone now accounts for 45 percent of what airlines spend to keep their planes in the air. That's not a minor line item. It's the difference between a sustainable business and one forced to pass costs directly to passengers. The Associação Brasileira das Empresas Aéreas, the country's airline industry association, had watched the Petrobras announcement with alarm, knowing exactly what would follow: pressure to raise ticket prices or absorb losses that would eventually force their hand anyway.

Biodiesel carries its own weight in the economy. Mixed into the diesel sold at pumps across the country, it touches nearly every movement of goods and people. A truck hauling cargo across state lines, a bus carrying commuters to work, a delivery van making its rounds—all of them run on fuel that contains biodiesel. When the cost of that blend rises, the effect ripples outward, raising the price of everything transported, which is to say, almost everything.

The government's April package came with a price tag of 30.5 billion reais in foregone tax revenue. That's the public cost of trying to hold the line against inflation in fuel. The exemptions for kerosene and biodiesel represent a deliberate choice: these two inputs are too strategically important to let market forces alone determine their price. Airlines cannot simply absorb a 45 percent cost shock. Transport companies cannot absorb it either. And if they pass it along, consumers feel it in ticket prices and grocery bills.

What remains unclear is whether exemptions alone will be enough. Petrobras sets the price at the refinery gate. Tax relief can soften the impact, but it cannot override the underlying economics of crude oil markets and the company's own financial pressures. The government has bought time and breathing room for the sector, but the fundamental tension remains: how long can the state subsidize fuel costs before the fiscal burden becomes unsustainable, and what happens when it does?

Why did the government choose to extend these two exemptions specifically, rather than letting them expire?

Model

Because they touch everything. Aviation kerosene is now nearly half of what it costs an airline to operate. Biodiesel is in every liter of diesel sold in the country. If you let those prices spike, you're not just affecting one industry—you're affecting ticket prices, food costs, shipping. The government decided the fiscal cost of the exemption was smaller than the political and economic cost of not doing it.

Inventor

But doesn't that just delay the real problem? Petrobras still raised prices 50 percent.

Model

Exactly. The exemption is a buffer, not a solution. It keeps airlines from immediately raising fares and keeps transport costs from jumping overnight. But yes, it's temporary relief. The underlying issue—what Petrobras charges at the refinery—that hasn't changed.

Inventor

How much is this costing the government?

Model

The whole April package was 30.5 billion reais. We don't know the exact breakdown for just these two exemptions, but it's substantial enough that the government felt it needed to announce it as a major intervention.

Inventor

Will consumers notice this?

Model

They might not notice the exemption itself, but they'll notice if it works—if their plane tickets don't jump 20 percent and their groceries don't get more expensive. If it doesn't work, they'll notice that too.

Inventor

What happens if Petrobras raises prices again?

Model

Then the government faces a choice: extend more relief, which costs more money, or let the exemptions absorb the hit and hope it's enough. Either way, you're managing a problem, not solving it.
