Ethanol futures were on track to finish the week up 1.2%, while soybean oil finished 2.1% lower amid a correcting crude oil market.
The Nymex November ethanol futures contract settled 0.84% higher on Thursday at $2.09 per gallon on Thursday.
The Chicago Board of Trade October soybean oil futures contract settled 1.43% lower at 67.70 cents per pound on Friday and the CBOT November soybean futures contract closed 0.08% lower on Wednesday at $13.19 per bushel.
As a derivative of soybean feedstock, soybean oil's market is tied to the broader soybean complex.
Rhett Montgomery, DTN analyst, said weekend profit-taking gripped row crop futures on Friday, with the soybean complex leading the way lower.
"Soybean oil prices dropped for a third straight session as well, reaching three-week lows on the December contract and pressured primarily by outside energy weakness, particularly in diesel futures," Montgomery said.
On Friday, the Commitments of Traders Report showed that for the week ending Sept. 15, 2026, money managers remained net long the ethanol futures and options markets by 7,325 contracts.
The COT Report showed that money managers are net long the soybean oil market by 110,894 contracts, after adding 9,000 long contracts from the previous week.
