Spot diesel fuel in New York Harbor strengthened relative to futures after a government report showed regional stockpiles fell to the lowest seasonal level in more than two decades while demand climbed nationwide.
Ultra-low-sulfur diesel gained 0.08 cent to 0.08 cent a gallon above futures on the New York Mercantile Exchange at 3:35 p.m., according to data compiled by Bloomberg.
Stockpiles of diesel in the Central Atlantic region known as PADD 1B, including New York Harbor, slipped 1.9 million barrels to 18.8 million barrels in the week ended Nov. 1, the lowest level for the time of year in government data going back to 1990, according to Energy Information Administration data.
Nationwide demand rose 8.6 percent to 4.51 million barrels a day, the highest since February 2008, according to the data. November marks the start of the U.S. heating season.
Refiners including Phillips 66 and PBF Energy Inc. carried out seasonal maintenance on the U.S. East Coast and Colonial Pipeline Co. allocated shipments on lines serving New Jersey, signaling strong demand.

The same spread for Gulf Coast refiners, based on West Texas Intermediate oil in Cushing, Oklahoma, fell 88 cents to $8.55 a barrel. Conventional, 85-octane gasoline, or CBOB, in the region slumped 1.5 cents to 25.5 cents a gallon, the lowest since July 23.
