Brazil’s biodiesel producers are facing increasing margin pressure as high soybean oil costs, excess inventories and constrained demand weigh on contract negotiations for November and December 2026.
According to Platts, part of S&P Global Energy, logistics differentials negotiated between biodiesel producers and fuel distributors fell by more than R$30 per cubic metre compared with the September–October period. The decline pushed all regional indexes into negative territory, despite expectations that seasonal feedstock supply conditions would support higher contract fees.
Platts surveyed 54 companies between 23 and 30 October to calculate the volume-weighted average differentials, commonly known as fees, for biodiesel term contracts across Brazil’s main regions.
The largest reductions were recorded in Mato Grosso. The Sorriso–Nova Mutum microregion saw its fee decline by R$70/m³, while Cuiabá–Rondonópolis registered a reduction of R$35/m³. In Rio Grande do Sul, the differential fell by R$9/m³.
At the beginning of negotiations, producers had sought increases of approximately R$300/m³ compared with the previous two-month period to recover margins affected by higher feedstock costs.
Excess inventories and diesel supply constraints weigh on negotiations
The seasonal tightening of soybean oil availability during the inter-harvest period usually provides support to biodiesel contract fees towards the end of the year. However, this year’s market conditions have limited that support.
Distributors entered negotiations with outstanding biodiesel volumes from previous contracts, giving buyers greater leverage over prices. Constraints on diesel availability, including Petrobras quotas and uncertainty surrounding imported diesel demand, also affected purchasing activity.
Some producers initially resisted lowering their offers and accepted reduced sales volumes rather than commit to additional soybean oil purchases at elevated prices. Others eventually reduced their prices to remain competitive and meet contracting targets established by Brazil’s National Agency of Petroleum, Natural Gas and Biofuels (ANP).
Currency depreciation adds to feedstock costs
The depreciation of the Brazilian real against the US dollar has added another challenge for biodiesel manufacturers by increasing domestic feedstock costs.
Brazilian biodiesel contract pricing incorporates Chicago Board of Trade (CBOT) soybean oil futures, the vegetable oil price basis at the port of Paranaguá and the real–US dollar exchange rate. Changes in these benchmarks therefore influence the cost structure and negotiated margins of producers.
Following the currency movement, some manufacturers attempted to raise their spot biodiesel offers. However, subdued market activity meant that many of these offers did not translate into completed transactions. Spot trading remained limited, with producers expecting liquidity to remain subdued until exchange-rate conditions stabilise.
Market pressure expected to continue into early 2027
Market participants expect challenging conditions to persist into early 2027, when biodiesel demand typically weakens seasonally.
Some processors are already limiting contracted sales to volumes supported by soybean oil feedstock they have previously purchased and allocated to production. This approach is intended to avoid further exposure to high raw material prices.
The combination of elevated feedstock costs, accumulated inventories and weaker seasonal demand could continue to constrain producers’ margins in the coming months.
Bioenergy Business Analysis
Brazil’s latest biodiesel contract negotiations highlight the pressure that feedstock costs and fuel-distribution conditions can place on producer profitability, even when seasonal supply patterns would normally support prices.
The decline in logistics differentials is particularly significant because these fees contribute to the margins producers receive under term contracts. Their movement into negative territory across regional indexes indicates that producers faced weaker negotiating conditions during the November–December contracting round.
The situation also illustrates the exposure of Brazil’s soybean-oil-based biodiesel industry to currency fluctuations. Since the pricing formula incorporates international soybean oil benchmarks, port price differentials and the exchange rate, movements in the real can affect domestic production economics.
