Platts transitions Brazil biodiesel contract fee indexes to volume-weighted average, Sept. 1

Platts, part of S&P Global Energy, has transitioned the calculation methodology for its Brazil biodiesel term contract fee indexes from a simple average to a volume-weighted average, effective Sept. 1, 2026.

The transition reflects feedback received from market participants and evolving trade flows in the Brazilian biodiesel term contract market. Platts understands that this segment accounts for about 90% of total transacted volumes, with the spot market accounting for the remainder. Using a volume-weighted averaging methodology improves transparency and more accurately captures trading levels within each two-month period, consistent with market participants' views.

Under this methodology change, region-specific term contract fees and corresponding volumes negotiated by market participants for each two-month period are used to calculate a bi-monthly volume-weighted average fee for each specified region. Platts will continue reviewing submitted information and may contact submitters to clarify any potentially anomalous data. Platts may also exclude data from the assessment calculation if it determines that the data is not representative of market value.

Assessments will continue to be published on the first business day of each two-month period (January, March, May, July, September and November). The cutoff for data submission remains at 13:00 Sao Paulo time on the last working day of the preceding two-month period.

The change affects the following assessments:

In addition to publishing two-month contract fees, Platts calculates and publishes daily ex-works (EXW) contract price assessments, along with related weekly and monthly averages, derived from the contract fees described above. In addition to the fees, these calculations incorporate Chicago Board of Trade soybean oil futures, the Platts Paranaguá vegetable oil differential, and adjustments for biodiesel density and the Brazilian real-US dollar exchange rate.

Under this methodology transition, the calculated contract price assessments below will also incorporate the updated volume-weighted fee rather than the simple average fee:

Brazil biodiesel term contract prices and fees are published in Energy Core, Biofuelscan and Biomass-based Diesel reports and appear on fixed pages PBF 0005 and PBF 0010.

The update of these symbols follows a proposal on June 22 and a decision note on July 20 ,
