Ethanol futures fell the most in seven weeks in Chicago as production costs eased with lower corn prices because rain may ease a drought in the U.S.
Rain may fall in parts of Iowa and Illinois this week and next, and the Midwest might get showers in the next 11 to 15 days, reducing severe moisture deficits from the worst drought since 1988, said Commodity Weather Group LLC in Bethesda, Maryland.
Denatured ethanol for August delivery fell 5.5 cents, or 2.1 percent, to settle at $2.596 a gallon at 2:15 p.m. on the Chicago Board of Trade, the biggest decline since June 1.
Corn for December delivery fell 7.25 cents, or 0.9 percent, to $7.7825 a bushel in Chicago. One bushel makes at least 2.75 gallons of ethanol.
