In July 2026, Brazil's ethanol market is being reshaped by a sharp change in production economics rather than fuel demand alone. Falling international sugar prices have encouraged mills to allocate more sugarcane towards ethanol, resulting in one of the largest production increases in the country's history. At the same time, lower ethanol prices are making the biofuel increasingly competitive with gasoline, supporting consumption even as supply continues to surge. The result is a market where production decisions, rather than seasonal demand patterns, are becoming the dominant driver of prices.
Leticia Correa, StoneX Brazil Market Intelligence Analyst, follows Brazil's sugar and ethanol markets through the country's production cycle and changing fuel economics. Her analysis combines crop fundamentals, biofuel policy and pricing dynamics to explain how shifts in mill economics are redefining Brazil's ethanol market during the 2026/27 season.
Key Themes from the Discussion
Lower global sugar prices have lifted Brazil's ethanol production mix from 49% to approximately 58%.
Record ethanol supply is expected to increase production by around 12% during the 2026/27 season.
Growing fuel demand and possible policy changes support consumption but are unlikely to fully offset the record supply increase.
Brazil Sugar Economics Shift Ethanol Production Higher
Brazil's ethanol market is becoming increasingly driven by relative commodity prices rather than traditional harvest cycles. Correa explains that "the 2026/27 crop started with mills favoring ethanol over sugar" because of "a lower price of sugar in the international market". As a result, mills have significantly increased the share of sugarcane directed towards ethanol production, creating a substantial expansion in available supply. This production response demonstrates how quickly Brazil's integrated sugar and ethanol industry can adjust output when market incentives change, reinforcing the country's flexibility as the world's largest sugar producer and a leading biofuel supplier.
Record Ethanol Supply Limits Price Recovery
Brazil's record ethanol output is expected to keep prices under pressure despite improving consumption. Correa notes that ethanol production is projected to grow by around 12% this season, adding that "prices have dropped a lot, about 23% since April", reflecting "the significant supply shock". Stronger competitiveness against gasoline and potential regulatory support are expected to stimulate demand but not fully absorb the additional production. Unless supply growth slows materially, ethanol prices are likely to remain below previous seasonal norms throughout much of the remainder of 2026.
Frequently Asked Questions
Why are Brazilian mills producing more ethanol than sugar?
Lower international sugar prices have made ethanol more attractive economically, encouraging mills to increase the proportion of sugarcane allocated to ethanol production.
Why have ethanol prices fallen in Brazil?
Record production has created a significant supply shock. Although demand is improving because ethanol is cheaper than gasoline, supply growth remains large enough to keep prices under pressure.
Could government policy increase ethanol demand?
Yes. The proposed increase in Brazil's mandatory gasoline blend and the possible removal of fuel tax relief could both improve ethanol competitiveness and support additional consumption.
