Shares of Brazilian state-controlled oil company Petrobras traded lower on Friday, March 13, 2026, after the firm announced it would raise diesel prices for domestic distributors effective the following day. The move increases the average price for diesel A, sold to distributors, by 0.38 real per liter to 3.65 reais per liter. For consumers at service stations, where diesel is blended with biodiesel, the effective increase translates to 0.32 real per liter.
The price adjustment comes amidst significant government intervention in Brazil's energy markets. In a bid to shield households, truckers, and farmers from the impact of soaring global oil prices—driven in part by geopolitical tensions in the Middle East—the administration of President Luiz Inacio Lula da Silva eliminated federal diesel taxes. Concurrently, it imposed a new 12% tax on crude oil exports, a measure that directly curtails the windfall profits typically enjoyed by exporters like Petrobras when international prices surge.
Diesel is a particularly sensitive fuel in Brazil, which imports approximately 30% of its supply. The Finance Ministry acknowledged the inflationary pressure, raising its 2026 inflation projection to 3.7% from 3.6%, citing an expected 10.8% rise in average oil prices. In U.S. trading, Petrobras American Depositary Receipts (ADRs) were down $0.25 to $18.72 as of 1533 UTC, underperforming global peers like Exxon Mobil and Shell, which advanced.
Petrobras stated its board has approved joining a government-led voluntary diesel subsidy program, pending the finalization of guidelines from Brazil's National Agency of Petroleum, Natural Gas and Biofuels (ANP). The company said the subsidy aligns with its commercial policy, which aims to protect customers from full exposure to short-term volatility in international crude prices and exchange rate fluctuations.
Company executives are navigating a complex landscape. While Chief Logistics Officer Claudio Schlosser noted "better margins" on exports this week, CEO Magda Chambriard emphasized that sudden price shifts would not be passed on to Brazilian consumers. CFO Fernando Melgarejo added that there is no room for extraordinary dividends "at this time," signaling a cautious capital allocation approach.
This caution follows a period of robust financial performance. Last week, Petrobras reported a fourth-quarter net profit of 15.6 billion reais, bolstered by record exports of 1.2 million barrels per day—a 41.7% surge in international sales. The board also proposed an 8.1 billion real interest-on-equity payout, a shareholder distribution mechanism common in Brazil.
The government's fiscal reliance on Petrobras remains substantial. The company disclosed it paid 277.6 billion reais in taxes and other contributions to state coffers in 2025, representing roughly 7% of Brazil's total tax haul, underscoring its role as a key fiscal engine.
Market analysts point to a potentially challenging road ahead. While investment bank Goldman Sachs predicted Brent crude could surpass $100 per barrel this month, it also forecast a retreat to the low $70s later in the year if Middle East tensions ease. Such a scenario could leave Petrobras managing domestic price caps without the earnings boost of sustained high oil prices, squeezing its financial flexibility.
Energy consultant David Hewitt of Hewitt Energy Perspectives noted that oil equities often decouple from the underlying commodity as prices approach $100 per barrel, a dynamic he observed was playing out in current trading. The interplay between government policy, global crude markets, and domestic price controls continues to define the investment narrative for Petrobras.
