CBOT soybean oil falls 7% as US biofuel policy uncertainty weighs on demand outlook

The Chicago Board of Trade's soybean oil futures experienced a significant drop, falling more than 7% across three trading days leading up to August 24. This decline, amounting to 5.06 cents per pound, or 7.1%, was primarily attributed to uncertainty surrounding US biofuel policies. The Environmental Protection Agency (EPA) announced an extension to the Sept.

1 deadline for refiners to demonstrate compliance with the 2025 Renewable Fuel Standard obligations, though no new deadline has been set. The EPA also intends to decide on outstanding small-refinery exemption petitions by the end of August, which could potentially make 1.2 billion-1.8 billion Renewable Identification Numbers (RINs) available for compliance.

This development led to a sharp decrease in RIN values, further contributing to the decline in soybean oil prices. The weakening biofuel credits raised concerns about the economic incentives supporting demand for biodiesel and renewable diesel feedstocks. While US biofuel demand has become a crucial factor in soybean oil pricing, the CBOT soybean oil futures were particularly sensitive to changes in Renewable Fuel Standard (RFS) policy and RIN values.

However, the sharp futures correction did not fully reflect in Argentine and Brazilian physical soybean oil prices, as export basis levels significantly strengthened. The CBOT October soybean oil futures fell 3.2% to 67.26 cents per pound on August 24, while Argentine soybean oil FOB Up River for October loading dropped 66 cents per metric ton, and the Argentine October basis strengthened by 220 points to -1,320 points against CBOT October futures.

Similarly, Brazilian soybean oil FOB Paranaguá for October loading decreased by $5.07 per metric ton, and the basis strengthened by 200 points to -1,300 points. This price action widened the divergence between US futures and South American physical soybean oil markets, highlighting the different forces impacting the markets: US soybean oil futures were adjusting to uncertainty surrounding biofuel demand, while South American physical values remained supported by export demand and regional commercial activity.
