Ethanol margins in the Corn Belt fell to negative $3.92 a gallon, the lowest since at least 2010, according to Refinitiv data. Natural gas prices hit multi-year highs during the cold snap, prompting some producers to cut ethanol output and sell their gas for a profit.
Lower ethanol output reduces corn grind and DDGS production, which is bearish for corn and DDGS prices. Higher natural gas costs raise processing expenses and support natural gas prices.
After 357 past bearish weather events, Corn moved a median -0.3% over 5 sessions (44% higher; middle half -2.2% to +1.3%), and -0.5% over 20.
