Sept. 23 (Bloomberg) -- U.S. Gulf Coast gasoline weakened relative to futures as regional refineries running more crude for the season than any other year on record boost supplies in the region.
Reformulated, 84-octane gasoline, or RBOB, on the Gulf Coast slid 1.25 cents to a discount of 15.75 cents a gallon versus New York Mercantile Exchange futures at 3:54 p.m., according to data compiled by Bloomberg.
Gulf Coast refiners processed 8.47 million barrels of crude in the week ended Sept. 6, the most for this time of year in Energy Information Administration data back to 1993 and 19 percent above the average of the past five years.
Inventories are at a five-year seasonal high on the Gulf Coast, the region known as PADD 3. Stockpiles of gasoline in the area narrowly declined to 77.7 million in the week ended Sept. 13 after rising by more than 2 million barrels the week before, Energy Information Administration data showed.
