RIO DE JANEIRO, March 4, 2026, 10:58 (BRT)
- Petrobras plans to monitor oil prices through the next week, holding off on any decision about gasoline and diesel adjustments in Brazil for now.
- Oil prices jumped as traders worried about possible supply snarls near the Strait of Hormuz, pushing fuel costs—and inflation—back to the forefront.
- If the price shock drags on, import economics take a hit—potentially muddling Brazil’s anticipated rate-cut trajectory.
Petrobras isn’t ready to move on gasoline or diesel prices in Brazil just yet. Chief Executive Magda Chambriard said the company wants to see more decisive trends in the oil market before making any adjustments, after Iran’s conflict pushed crude higher. “Petrobras historically does not pass through sudden oil prices volatility,” Chambriard told Reuters.

Timing is key in Brazil, where fuel costs feed directly into inflation and rate forecasts. Treasury Secretary Rogerio Ceron warned this week: a prolonged oil shock might force the country to wrap up its expected rate-cut cycle sooner, despite policymakers indicating plans to kick off easing at the March 17-18 meeting.
Crude prices kept swinging. Brent jumped 4.7% to settle at $81.40 a barrel on Tuesday, marking its highest close since January 2025, Reuters said, as Middle East tensions escalated and maritime threats increased. “The market is thinking there might be a quicker resolution than previously feared,” Price Futures Group senior analyst Phil Flynn told Reuters.

Petrobras imports crude to blend with its own output, but those barrels come with a price tag—one that’s tangled up in domestic politics and inflation concerns. Executives have flagged other logistics options if bringing in Persian Gulf supply turns pricier or more complicated.
Here, “pass-through” means Petrobras bumps up domestic fuel prices fast when international crude and freight costs climb. The company has maintained that cushioning short-term volatility gives households and businesses a break. Still, when its prices drift too far below global benchmarks, fuel importers start to feel the squeeze.
Petrobras’s shift on gasoline prices spills over into Brazil’s biofuels sector, giving the country’s millions of flex-fuel motorists the option to pivot between gasoline and hydrous ethanol. As oil markets reel once again, ethanol “could play a role in addressing that challenge,” said Edmundo Barbosa, president of the Paraiba state ethanol association Sindalcool. Argus Media
With the Strait of Hormuz risk still clouding supply routes, banks are adjusting their oil price outlooks. Goldman Sachs bumped its Q2 2026 Brent projection up by $10, landing at $76 per barrel. UBS, meanwhile, has Brent averaging $71 in the first quarter—suggesting prices could approach $80 in March. J.P. Morgan didn’t mince words, flagging the potential for multi-million barrel-per-day supply losses if the strait remains closed.
The flip side isn’t complicated. Should crude remain elevated—or jump even higher—Petrobras is left with tough options: raise prices, swallow the extra costs, or create market distortions that could deter imports. Each move carries a consequence, whether it’s squeezing margins, pushing up inflation, or messing with the fuel supply balance.
Brazil’s downstream sector has its own tangle of rivalry. Raízen and Vibra Energia, for example, run their distribution and refining businesses in a landscape dominated by Petrobras, which continues to anchor wholesale supply prices. Swings in pricing can quickly decide which players take on imports—or get stuck carrying inventory.
Petrobras hasn’t committed to a timeline on pricing yet. All eyes are split—oil and shipping moves near Hormuz on one side, Brazil’s central bank decision coming up mid-March on the other.
