1) Stock Market Record And The Impact Of Interest Rates: Why This Matters For Energy And Oil
The week was marked by an important movement in the stock market. The Ibovespa closed at 142,640.14 points, signaling a rebound after weeks of volatility. The ETF UVP11 also advanced, closing at 102.9, up 0.43%.
This performance is directly linked to expectations of interest rate cuts in Brazil and the United States. Lower financing costs impact the entire production chain, but sectors like energy and oil are even more benefited. Indebted companies that need to raise funds for expansion or refining tend to strengthen in cycles like this.
For the investor: Interest rate cuts are not only good news for the stock market, but also for strategic companies tied to oil and fuels that operate with tight margins and high capital volumes.

2) Supreme Court, Trial And Amnesty: Politics Pressures Brazil’s Risk
While the markets breathed a sigh of relief with falling interest rates, Brasília brought another factor of uncertainty. The Supreme Court started the trial of former President Jair Bolsonaro and seven others, accused of crimes ranging from armed criminal organization to attempted coup d’état. The process, led by the Supreme’s first chamber, generated criticism from the defense regarding impartiality, as three of the five ministers were questioned for alleged impediments.
At the same time, the topic of amnesty advanced in Congress. Two distinct projects from Davi Alcolumbre and Hugo Mota seek to pardon defendants involved in the events of January 8. In some formats, the measure could even make Bolsonaro eligible in 2026, which divides even the government’s base.
This institutional clash is not just political. It directly affects the business environment, as it increases the perception of risk. Investors demand a higher premium to invest in Brazil when they see legal instability, which can increase the cost of infrastructure, energy, and oil projects.
Why does this affect your wallet? Because institutional risk enters the price. When investors see prolonged uncertainty, they demand a higher premium to finance companies, making projects, including those in oil and energy, more expensive. Additionally, clashes between branches of government and external noise (such as mentions of the Magnitsky Act and potential sanctions) raise volatility in the currency, a sensitive component in the price formation of fuels and in dollarized CAPEX.
3) Banks, Credit And Oil Companies In Adaptation
In the financial sector, relevant movements caught attention. Banco do Brasil had its price target reduced by Itaú to R$ 23, reflecting risks in agricultural credit. Meanwhile, BRB experienced a rollercoaster week: after falling following the Central Bank’s rejection of the purchase of another bank, it closed up 11.71%, quoted at R$ 10.
These adjustments are important because credit is the basis for expanding the oil sector. Logistic bases, pipelines, and fleets depend on accessible financing. If banks freeze or increase the cost of resources, companies in the sector need to reassess their plans.
Raízen, for example, rose more than 3% during the week following news of unfair competition affecting its operations. The company is also in the process of financial restructuring, selling assets and strengthening capital to reduce debt. It is a reflection of how fuel-related companies need to balance their operations amid volatility.
4) Foreign Trade: US Recovers, China Advances
In foreign trade, the signals are mixed. Brazilian exports to the United States fell 18% in August, according to statements highlighted in Congress. Small and medium-sized enterprises are the most affected by this decline. The federal government has announced R$ 10 billion in credit via BNDES under the “Sovereign Brazil” program to mitigate this.
Meanwhile, China is increasing its presence in Brazil. The country is now the third-largest destination for Chinese capital, with over R$ 2 billion annually in investments, spread across more than 40 projects. Chinese involvement covers strategic sectors such as energy, oil, technology, and increasingly, electric vehicles. BYD, for example, has already surpassed traditional brands like Nissan, Renault, and Honda in 2025 sales in Brazil.
This advancement shows the competition between powers for space in Brazil. For the oil sector, it means that external investments will continue to dictate the pace of energy infrastructure, even in a scenario of transitioning to new matrices.
5) Inflation, Social Program And Fiscal Risk
In the macroeconomic field, the IPCA completed the 14th consecutive week of declining expectations for 2025. The cooling of the economy in services, trade, and industry reinforces the room for interest rate cuts.
On the other hand, fiscal measures raise doubts. The Gas Program, planned for 2026, anticipates the distribution of gas canisters to 50 million people, with an estimated cost of R$ 5 billion. Although it is a relevant social action, analysts are concerned about the impact on an already pressured budget.
When the government overspends, the perception of fiscal risk rises. This pressures the exchange rate and ultimately reduces room for more aggressive interest rate cuts, again affecting the environment for investments in oil and energy.
6) Geopolitics And Oil: Global Tension On The Radar
In the international scenario, conflicts continue to dictate market moods. The war in Ukraine persists, with China, Russia, and India strengthening ties against the United States. North Korean leader Kim Jong-un has declared support for Russia, increasing pressure on the global chessboard.
In South America, the US has intensified its clampdown on Nicolás Maduro’s government, sending more than 10 fighter jets to the region. The possibility of an escalation is concerning, as any instability in producing countries or in the surrounding areas of Latin America has the potential to affect oil barrel prices.
7) What To Do Now (Without Magic Formulas)
- A rising stock market trend with falling interest rates favors energy and infrastructure.
- Political risk (Supreme Court agenda and amnesty) calls for cash, governance, and well-designed currency exposure.
- In the oil segment, prioritize companies with decreasing leverage, predictable contracts, and operational efficiency.
The movements of the week make it clear that Brazil is at the center of political, fiscal, and geopolitical disputes.
And, mainly: in a world of wars and uncertainties, what should be the role of oil in our energy future strategy?
