How Petrobras (PETR4) Handled the Jet Fuel Price Increase
Petrobras announced an 11.8% increase in the average selling price of aviation kerosene (jet fuel) for distributors, effective October 1, 2026. The price adjustment reflects the recent surge in international Brent crude quotations.
According to information released by the company, the decision to adjust fuel prices was driven directly by rising oil and petroleum product prices in international markets throughout September. This pass-through dynamic is part of the company's commercial strategy, aligning refined products with global costs to prevent severe pricing lags that could compromise its financial and operational health.
Aviation kerosene is one of the most sensitive inputs for the transportation sector, and adjustments of this magnitude typically squeeze the operating margins of airlines flying in the country. For investors, however, the move signals that Petrobras management remains attentive to external market swings, passing on crude oil volatility when necessary. The company explained that the increase reflects global market behavior, which faced heavy upward pressure over recent weeks due to supply bottlenecks and escalating geopolitical tensions.
Why Did Oil Prices Spike Globally?
The oil price surge was driven by escalating tensions in the Middle East and strategic decisions by major global players, such as the United States and China. On Thursday, October 1, the December Brent crude futures contract closed at $102.31 per barrel, posting a sharp gain of 4.37% (or an increase of $4.28). Meanwhile, West Texas Intermediate (WTI) crude in the U.S. settled at $92.87 per barrel, up 2.71% (or $2.45).
The primary catalyst for this jump, as reported by The Wall Street Journal, was news that the United States was dispatching a third aircraft carrier and up to 10,000 additional troops to the Middle East. This military deployment comes during a period of extreme political sensitivity, with U.S. President Donald Trump weighing the resumption of strikes against Iran following the midterm elections. In remarks to the press at the White House ahead of a campaign trip, Trump stated that Iran must sign a fair deal, or else it "will cease to exist."
Beyond the U.S. geopolitical factor, the fuel market faced a severe supply squeeze on the Asian side. As reported by Reuters, Chinese refineries suspended petroleum product exports. This combination of military threats in a key producing region and fuel retention by the world's second-largest economy sparked immediate fears of a global shortage, pushing Brent prices past the $102-per-barrel mark.
What This Means for PETR4 Investors
International oil volatility and domestic price adjustments directly affect the attractiveness of PETR4 shares on the B3. On one hand, Petrobras's ability to adjust jet fuel by 11.8% demonstrates a commitment to passing on costs, which protects cash flow and dividend distributions to shareholders. During periods of rising oil prices, integrated oil companies typically benefit from higher reserve valuations and crude export revenues.
On the other hand, heavy volatility in crude prices—swinging rapidly between peaks of $102.31 and profit-taking phases—adds volatility to the stock on the Brazilian exchange. On Friday morning, October 2, Brent futures contracts fell about 3%, with the barrel trading at $99.87. This profit-taking reflects global investor caution ahead of key macroeconomic data releases. For investors holding PETR4 in their portfolios, these daily swings require patience, as the stock tends to track the mood of foreign exchanges and geopolitical headlines closely.
Watch for Geopolitical Risk: Brent crude volatility directly impacts oil stocks on the B3 and fuel price decisions. While Petrobras can pass along part of the increases, instability in the Middle East can trigger sharp short-term swings.
What to Watch in Global Markets in the Coming Days
Investor focus is now split between developments in the Middle East and the release of the U.S. September employment report (payroll). Wall Street consensus projects the creation of 84,000 jobs and the U.S. unemployment rate holding at 4.1%. These numbers are crucial because they serve as a compass for the Federal Reserve's next steps in monetary policy.
Currently, fed funds futures pricing points to a 72% probability that the Federal Reserve will keep interest rates unchanged at its October meeting. Higher U.S. interest rates tend to strengthen the dollar and make commodities more expensive for buyers using other currencies, which can act as a natural brake on further oil price rallies. Therefore, Petrobras investors should monitor not only the state-owned company's pricing decisions but also global geopolitical temperatures and the employment data driving the dollar and global interest rates.
The Rico aos Poucos Verdict
The 11.8% jet fuel price adjustment shows that Petrobras (PETR4) continues passing along international market pressures to protect its operating margins. However, extreme volatility in Brent crude—which spiked to $102.31 amid geopolitical tensions before pulling back to $99.87 on profit-taking—calls for caution. Our stance on the stock remains neutral for now, with a recommendation to monitor Middle Eastern developments and U.S. macroeconomic data closely.
