Demand for ethanol in Brazil is expected to remain strong in 2025, as increasing corn ethanol output and less-than-expected crop damage from fires in 2024 should allow retail prices for the biofuel to remain competitive with gasoline.
Production of corn-based ethanol in Brazil's center-south rose to 5.25bn l (100,200 b/d) in January-November, a 30pc increase from the same period in 2023, according to regional industry association Unica. The volume accounts for 17pc of the 31.17bn l of ethanol produced in the region during the period.
Greater supply of corn-based ethanol should add downward pressure to prices, making ethanol more attractive at retail pumps. The country has 41 corn ethanol plants in operation, according to a survey by agronomist and researcher Rafael Vieira, with more under construction.
Dryer weather and wildfires that hit sugarcane fields in 2024 do not appear to be as devastating as initially expected, so biofuel production from sugarcane could be higher than initially expected.
Recent data support this outlook. Sugarcane crushing in the center-south surpassed 600mn metric tonnes (t) in April-November, on the high end of the 585mn-605mm t analysts estimated for the full 2023-24 cycle because of the fires and drought.
Crushed volumes in the next harvest will depend heavily on the weather in December-January. Rains in this period are crucial for the development of sugarcane plants, as they are in their early growing stages. The more it rains in these two months, the higher the volume processed in 2025-26 should be.
Sugar production
Rains should also influence sugarcane quality, which affects the production mix, one of the vectors that can sway ethanol prices.
The drought made sugarcane less fit for sugar production in 2024. But if the next two months are more humid, producers will be able to achieve a more sugary mix as desired, which tends to boost biofuel prices.
Investments in crystallization capacity in recent years are expected to finally translate into greater sugar production in 2025. This is what producers want, as the sweetener currently trades at a premium to ethanol.
This trend is supported by India's growing appetite for Brazilian sugar. The Asian country will increase its ethanol blending mandate in 2025, a change that will shift the sugarcane processing profile of the country and create room for Brazilian sugar to fill the resulting supply gap.
Hedgepoint Global Markets analyst Livea Coda expects the sugar mix at 51.9c in 2025-26, with room for a revision if summer rains are confirmed. Hedgepoint projects sugarcane crushing at 600mn t in the next harvest, with the possibility of reaching 620mn t if rains "excel". Based on weather forecasts, she expects sugarcane quality to improve. Coda considers it unlikely that ethanol production will pay more than sugar in Brazil, considering that slower growth in the Brazilian economy next year should keep motor fuel demand below 2024 volumes.
Analyst Arnaldo Correa, founder of Archer Consulting, predicts the sugar mix at 51.5pc in the next cycle. He expects strong crushing after an increase in sugarcane cultivation area this year, but Correa is not yet ready to make a volume prediction.
In his analysis, US president-elect Donald Trump's protectionist policies are also a point of concern for 2025, Correa said. At the start of Trump's second four-year term, the US is expected to impose higher tariffs on products from China, a move that could lead the Asian giant to replace US grains with Brazilian grains. That could lead to higher corn ethanol prices in Brazil, Correa said.
