During the week ending on June 20, U.S. ethanol output fell for a second straight week while inventories rose, according to data from the Energy Information Administration. Production declined to an average of 1.081 million barrels a day, which is down from the 1.109 million barrels during the prior week and the lowest total since the seven days ending on May 23. The Midwest, which produces the most ethanol in the country, produced an average of 1.023 million barrels per day, down from 1.052 million barrels during the previous week, the lowest total in just over a month. Gulf Coast production dropped to 26,000 barrels a day from 27,000 the prior week, the agency said. That was the entirety of the losses as East Coast and Rocky Mountain production held steady from the prior week. The West Coast saw the only increase, rising from 8,000 to 10,000 barrels a day.
