Petrobras Scraps Gasoline Price Hike Hours After Announcing It
Brazil · Energy
Key Facts
—The U-turn. Petrobras announced a gasoline price increase for distributors on the night of Wednesday, September 9, and cancelled it hours later, in a correction issued shortly after midnight.
—The numbers. The first notice pointed to an average distributor price of R$3.24 per liter (about US$0.63); the corrected one sets it at R$3.05 (about US$0.59) — a net reduction of R$0.19 (about US$0.04) once a new federal tax cut is applied.
—The trigger. A R$0.44-per-liter (about US$0.09) federal subsidy under provisional measure MP 1.358/2026 expired on Wednesday, the same day the government signed a decree cutting federal fuel taxes for 30 days.
—The explanation. Petrobras said only that the change “will correspond to the suspension of the discount”; market coverage by InfoMoney noted the reversal came without further explanation.
—The context. The episode lands 24 days before the October 4 election, with the federal government — Petrobras’s controlling shareholder — campaigning partly on cheaper fuel.
Petrobras announced a gasoline price increase for distributors on Wednesday night and cancelled it before dawn, a whiplash episode with no coherent public explanation that lands in the middle of Brazil’s election campaign, with the government as the company’s controlling shareholder.
What Petrobras Announced — and Withdrew Overnight
The sequence began on the evening of Wednesday, September 9. In a notice to the market, Petrobras said it would stop applying a discount of R$0.44 per liter (about US$0.09) on gasoline A — the pure gasoline sold to distributors — and flagged an adjustment of R$0.19 per liter (about US$0.04). The arithmetic pointed to an average sale price to distributors of R$3.24 per liter (about US$0.63), effective Thursday.
Hours later, shortly after midnight, the company issued a correction. “Contrary to what was previously announced, the change in Petrobras gasoline prices at points of sale will correspond only to the suspension of the discount,” the new note said, according to O Globo. “For distributors, the effect will be a reduction of R$0.19 (about US$0.04) in the perceived price with taxes.”
The net result: the average distributor price stands at R$3.05 per liter (about US$0.59), not the R$3.24 per liter (about US$0.63) first flagged. Reuters headlined the episode “Petrobras walks back gasoline price hike”; O Globo called it a cancellation of the adjustment “hours after announcing it.” InfoMoney’s market desk noted the company reversed the decision “without providing further explanations.” (Exchange rates throughout this article use roughly 5.15 reais to the US dollar, the level quoted on September 10.)
The Tax Decree Behind the Confusion
The backdrop is a rapid reshuffling of Brazil’s fuel-tax architecture. Since mid-year, pump prices had been cushioned by an “economic subsidy” of R$0.44 per liter (about US$0.09) created by provisional measure MP 1.358/2026, which expired on Wednesday.
To replace it, President Lula signed a decree on September 9 cutting the federal PIS/Pasep and Cofins taxes on gasoline by R$0.63 per liter (about US$0.12), leaving a residual federal load of R$0.16 per liter (about US$0.03), and zeroing the same taxes on hydrous ethanol, a cut of R$0.19 per liter (about US$0.04). The Finance Ministry says the measure runs from September 10 to October 9 and “replaces and expands” the expired subsidy. A related budget measure frees up R$6.6 billion (about US$1.3 billion, per Reuters) for fuel subsidies.
Petrobras’s first notice on Wednesday night appeared to account for the expiring subsidy but not the new tax cut. The corrected version netted the two out — converting what read as an increase into a small reduction. Whether the initial notice was a drafting error or a decision reversed under political pressure, the company has not said.

Why the Episode Matters Politically
Fuel prices are among the most politically sensitive numbers in Brazil, and never more so than now: the first round of the presidential election is on October 4, and polls show a statistical tie between Lula and Senator Flávio Bolsonaro. The federal government is Petrobras’s controlling shareholder, and the 30-day tax cut covers the entire remainder of the first-round campaign.
The whiplash also revives an old tension. Petrobras formally sets prices by import-parity principles, but major adjustments during election periods have repeatedly collided with the political calendar — most famously in the run-up to the 2022 vote. A announced-then-cancelled increase, whatever its cause, feeds the opposition’s argument that fuel policy is being managed for the campaign rather than for market logic.
For now, the government’s preferred narrative is the decree itself: lower federal taxes on gasoline and ethanol through October 9, financed by a subsidy package worth about US$1.3 billion, at a moment when Brent crude has traded near US$100 a barrel amid the Middle East war premium.
What Drivers Will Actually Pay
For consumers, the relevant figure is not Petrobras’s refinery-gate price but the pump price, which also includes distribution margins, state ICMS tax and mandatory ethanol blending. The company’s correction says the net effect for distributors is a reduction of R$0.19 per liter (about US$0.04) in the perceived price including taxes.
Whether the full cut reaches the pump will be visible in the weekly fuel surveys of regulator ANP over the coming days. Distributors and gas stations are not obliged to pass on the entire reduction, though the government has publicly framed the decree as money that must reach consumers.
For foreign readers trying to make sense of the episode, the essentials are these: a subsidy expired, a tax cut replaced it, Brazil’s state-controlled oil company miscommunicated the net effect for a few overnight hours, and the correction happened to land in the final stretch of a dead-heat election.
Frequently Asked Questions
Did Petrobras raise gasoline prices or cut them?
Neither, in the end. Petrobras announced an increase for distributors late on September 9, then cancelled it after midnight. With the new federal tax cut applied, the perceived price for distributors falls by R$0.19 per liter (about US$0.04), to an average of R$3.05 (about US$0.59).
Why did Petrobras cancel the increase?
The company said only that the price change “will correspond to the suspension of the discount,” correcting its earlier notice. It has not explained why the increase was announced in the first place; market coverage described the reversal as coming without further explanation.
What did the government’s fuel decree do?
Signed on September 9, it cuts federal PIS/Cofins taxes on gasoline by R$0.63 per liter (about US$0.12) and zeroes them on ethanol between September 10 and October 9, replacing an expired R$0.44-per-liter (about US$0.09) subsidy. Reuters put the related subsidy package at about US$1.3 billion.
