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

Chicago Board of Trade soybean oil futures fell more than 7% over the three trading sessions through Aug. 24 as uncertainty surrounding US biofuel policy reduced some of the demand premium that had been supporting vegetable oil prices.

CBOT December soybean oil futures declined from 71.32 cents/lb on Aug. 20 to 66.26 cents/lb on Aug. 24, a drop of 5.06 cents/lb, or 7.1%.

The decline accelerated after the US Environmental Protection Agency said it plans to extend the Sept. 1 deadline for refiners to demonstrate compliance with their 2025 Renewable Fuel Standard obligations. EPA has not announced a new deadline, although market sources said a 30-90 day extension was under consideration.

The agency also intends to decide outstanding small-refinery exemption petitions by the end of August. Market participants estimate the exemptions could make 1.2 billion-1.8 billion RINs available for compliance, increasing expectations for greater availability of biofuel credits.

The developments triggered a sharp decline in Renewable Identification Number values, including biomass-based diesel credits, which fell to around $1.92 Aug. 24, their weakest level since late April.

For soybean oil, weaker biofuel credits raised concerns that the economic incentive supporting biodiesel and renewable diesel feedstock demand could soften. US biofuel demand has become an increasingly important component of soybean oil pricing, leaving CBOT futures particularly sensitive to changes in RFS policy and RIN values.

South American basis cushions CBOT decline

The sharp futures correction was not fully reflected in Argentine and Brazilian physical soybean oil prices, as export basis levels strengthened substantially.

CBOT October soybean oil futures fell 3.2% to 67.26 cents/lb Aug. 24, while Platts, part of S&P Global Energy, assessed Argentine soybean oil FOB Up River for October loading at $1,191.82/mt, down 66 cents/mt from Aug. 21.

The Argentine October basis strengthened 220 points to minus 1,320 points against CBOT October futures, offsetting almost the entire futures decline.

Brazilian soybean oil FOB Paranaguá for October loading was assessed at $1,196.23/mt, down $5.07/mt, while the basis strengthened 200 points to minus 1,300 points.

The price action widened the divergence between the US futures and South American physical soybean oil markets. While CBOT December soybean oil lost 7.1% in three sessions, sharply stronger FOB differentials insulated Argentine and Brazilian outright values from most of the decline.

Market participants said the contrasting moves highlighted the different forces affecting the markets: US soybean oil futures were repricing uncertainty surrounding biofuel demand, while South American physical values remained supported by export demand and regional commercial activity.
