U.S. ethanol production climbed to a four-week-high in early October, although gasoline demand and ethanol exports weakened. That’s according to data from the Energy Information Administration analyzed by the Renewable Fuels Association. For the week ending October 9, ethanol production rose 1.1 percent to an average of 1.07 million barrels per day, equivalent to 44.73 million gallons daily. Output was 0.8 percent below the same week last year but remained 1.2 percent above the five-year average. Ethanol inventories increased 0.8 percent to 23.9 million barrels, nearly six percent higher than a year ago. Meanwhile, gasoline supplied to the U.S. market fell 4.1 percent to 8.41 million barrels per day, its lowest weekly level since late February. Ethanol exports also dropped 27.1 percent to a six-week low. Refinery and blender use of ethanol edged up slightly, but remained below year-ago levels.
