Ethanol declined the most in three weeks as corn fell on signs that demand for the grain may ease.
The biofuel dropped 1.4 percent. Corn futures decreased for the first time in three days on speculation that near-record supplies of ethanol will reduce purchases of the biggest U.S. crop, the primary ingredient in U.S. production of the alternative fuel.
Denatured ethanol for March delivery declined 3.1 cents to $2.184 a gallon on the Chicago Board of Trade. Corn for May delivery fell 1.8 percent to $6.335 a bushel.
Stockpiles in the U.S. rose for a ninth straight week to an all-time high of 21.5 million barrels in the week ended Feb. 10, the Energy Department said. Daily output is down 3.6 percent from the record set in December.
In cash market trading, ethanol was unchanged in the Gulf Coast at $2.225 a gallon and in New York at $2.24, according to data compiled by Bloomberg. Ethanol in Chicago was unchanged at $2.175 a gallon and on the West Coast the additive was steady at $2.295.
The biofuel is blended with gasoline to augment supply and meet federal mandates. There are 209 ethanol distilleries in the U.S., with the capacity to produce 14.8 billion gallons annually, according to the Renewable Fuels Association, a Washington-based trade group.
