Brazil's long-standing ethanol program is proving to be a crucial buffer against rising global oil prices, particularly as the conflict involving Iran, the United States, and Israel enters its fifth week. Nations like India and Mexico are now examining Brazil's energy security model as a potential blueprint.
The South American giant is partially shielded from international oil market volatility by its decades-old, cost-effective, and environmentally friendly ethanol initiative. Millions of Brazilian motorists have the option to fuel their vehicles with 100% sugarcane-derived ethanol or a gasoline blend containing 30% biofuel.
Brazil's extensive fleet of flex-fuel vehicles, capable of running on any combination of ethanol and gasoline, is unparalleled globally. The program Proálcool (Programa Nacional do Álcool), initiated in 1975, has successfully evolved to reduce the country's reliance on foreign oil.
While consumers worldwide grapple with significant price hikes, gasoline prices in Brazil saw a modest 5% increase in March, starkly contrasting the 30% surge observed in the United States. Analysts attribute this stability to Brazil's mature domestic biofuel industry, which enables the nation to absorb geopolitical shocks with minimal risk of fuel shortages.
Evandro Gussi, president of the Brazilian Sugarcane Industry Association (UNICA), emphasized that Brazil is "much better prepared than most countries" due to this viable alternative. The upcoming sugarcane harvest, set to commence in early April, is projected to yield a record 30 billion liters of ethanol, a 4 billion liter increase from the previous year. Gussi noted that this additional volume alone is equivalent to Brazil's total gasoline imports for the entirety of last year.
Despite being a significant crude oil producer and exporter, Brazil remains dependent on imports for refined fuels, sourcing from countries including the United States, Saudi Arabia, Russia, and neighboring Guyana. Nevertheless, ethanol has become integral to daily transportation, with 37.1 billion liters sold in 2025, according to the state-owned Energy Research Company (EPE). Its widespread availability provides Brazilians with both psychological and economic reassurance.
Research and Development
The success of Brazil's biofuel economy is deeply rooted in São Paulo, the country's industrial and agricultural heartland. Production methods encompass both high-tech, export-oriented 'megafarms' and smaller, family-run operations. State-funded research, exemplified by the Unicamp Ethanol Scientific Development Center in Campinas, also plays a pivotal role in advancing Brazilian biofuel technology. Luis Cortez, the center's coordinator, underscored the unique advantages of Brazil's program, asserting that investment in research ultimately translates into tangible benefits at the fuel pumps.
Diesel Sector Challenges
While the potential closure of the Strait of Hormuz has not significantly impacted Brazil's gasoline market, the nation faces considerable challenges with escalating diesel prices. Diesel is predominantly produced from imported crude oil and incorporates a smaller proportion of biofuels. Brazilian biodiesel, primarily derived from soybeans, constitutes only 14% of the diesel blend. This percentage is not expected to reach 30% until 2030, implying an immediate impact from the ongoing conflict.
Brazilian diesel prices climbed over 20% in March, prompting President Luiz Inácio Lula da Silva to propose import subsidies until May. Government estimates suggest Brazil needs to import between 20% and 30% of its monthly diesel requirements, with the majority originating from Russia. Brazilian authorities reported nearly 17 billion liters of diesel imported last year. For President Lula, who is seeking re-election in October, stabilizing diesel prices is paramount to avert trucker strikes and mitigate food inflation.
Rabobank calculations indicate that increasing the anhydrous ethanol blend in gasoline from the current 30% to 32%, a measure advocated by some segments of the sugar-energy sector, could displace 1.2 billion liters of gasoline over a 12-month period. This would effectively substitute 34% of fossil fuel imports, considering Brazil imported 3.5 billion liters of gasoline A last year. However, such a modification is contingent upon technical tests, which the Ministry of Mines and Energy (MME) is currently facilitating. Industry leaders anticipate that an increased blend would only be feasible next year.
Should an increased ethanol blend be implemented sooner, it would also permit a rise in hydrous ethanol prices (which compete with gasoline at the pumps) relative to fossil fuels. Hydrous ethanol prices are typically discounted against gasoline due to its lower energy yield, generally hovering around 70% — a level that fluctuates with biofuel supply. Rabobank estimates that an increase in the anhydrous ethanol blend to 32% would reduce the hydrous ethanol price discount by 2%.
Presently, gasoline maintains a 30% anhydrous ethanol content, and its average pump price in Brazil rose 6% in March amidst speculation surrounding the Middle East conflict's repercussions. This occurred despite Petrobras not increasing the price of gasoline A sold at its refineries. The state-owned company accounts for 80% of the country's gasoline A supply capacity.
Recent Investments in Biofuels
On March 25, Grupo Potencial, a conglomerate with interests in energy, fuels, and agribusiness, announced a significant investment of BRL 6 billion ($1.2 billion USD) by 2030. Carlos Eduardo Hammerschmidt, the company's Vice-President for Commercial, Institutional Relations, and New Investments, stated that the objective is to further develop their integrated supply chain model and expand operations within a rapidly growing market. The group is already a prominent player, holding the title of Latin America's largest single-plant biodiesel producer, with an annual capacity nearing 1 billion liters. Approximately 15% of all soybeans cultivated in Paraná are processed, directly or indirectly, by the company. In 2025, Grupo Potencial's revenue increased by 15% to BRL 12 billion ($2.4 billion USD), with new investments projected to boost revenue to BRL 20 billion ($4 billion USD) within four years.
In another development, RRP Energia, a subsidiary of Grupo Piccini, secured BRL 1 billion ($200 million USD) in financing from BNDES (National Bank for Economic and Social Development) for the construction of a corn ethanol plant in Tapurah, Mato Grosso. The new facility will have the capacity to produce up to 459 million liters of hydrous ethanol or 452 million liters of anhydrous ethanol annually. Additionally, it will process over 1 million tons of corn each year, yielding valuable by-products such as animal feed ingredients and corn oil. The BNDES credit covers more than 60% of the project's total investment, structured as a long-term loan with the bank serving as the primary financier. The funding originates from the Climate Fund and the BNDES Finem line, qualifying the project due to its association with renewable fuel production and its potential to substitute fossil fuel sources.
