Argentina's Energy Secretariat authorized increases of up to 2.07 percent in minimum purchase prices for biofuels, with ethanol up 2 percent and biodiesel up 2.07 percent, via resolutions 306/2026 and 307/2026. The government also froze fixed fuel taxes for November under decree 1305/2026.
Small administered biofuel price increases add little to fuel prices and have minimal impact on feedstock demand, so the effect on soybean oil or corn ethanol prices is limited.
After 196 past neutral policy events, Soybean Oil moved a median +0.1% over 5 sessions (52% higher; middle half -1.6% to +2.0%), and -0.5% over 20.
After 439 past neutral policy events, Corn moved a median +0.1% over 5 sessions (51% higher; middle half -1.3% to +1.2%), and +1.1% over 20.
